How We Increased Repeat Purchases with Tokenized Loyalty Programs So, let me share how we really ramped up our repeat purchases using tokenized loyalty programs. It's been quite a journey, and we've learned a ton along the way! By introducing a token system, we made it super easy for our customers to earn rewards. Every time they shopped with us, they earned tokens that they could later redeem for discounts or exclusive offers. People love feeling valued, and this approach really tapped into that feeling. We focused on keeping things simple and fun. Customers could easily track their token balances and see all the cool stuff they could get with them. The more they engaged with us, the more rewards they unlocked. It really motivated them to come back for more! Overall, this tokenized loyalty program not only boosted repeat purchases but also helped us build a stronger relationship with our customers. It’s amazing what a little creativity and understanding of your audience can do!

**Summary:** A major retail company managed to ramp up their repeat purchase rate by an impressive 18.6% in just 12 weeks! So, what was their secret? They ditched the old-fashioned “static points” system in favor of innovative, tokenized rewards that not only respect customer privacy but also play nicely with Salesforce and Shopify. This boost was mainly driven by customers who had previously been inactive.

Enterprise (Retail/CPG, Hospitality)

Here are a few key topics that are really important in our field:

  • SOC2: This is essential for making sure your service providers are taking care of your data security. It’s like a safety net for your sensitive information!
  • ISO/IEC 27001: Think of this as a guideline for keeping your info safe and sound. It’s all about managing your data securely and making sure it’s protected.
  • GDPR/CCPA DPIA: Keeping up with privacy rules is super important these days, and doing a Data Protection Impact Assessment is a great way to make sure you're on the right track.
  • Procurement: It's all about snagging the best deals without compromising on quality. That's the name of the game!
  • Data Residency: It's super important to know where your data is stored, especially when it comes to keeping things compliant and secure.
  • Salesforce Web3 Connect: Getting ready to dive into the future of the web with some amazing connections!
  • Shopify: This is an awesome platform for e-commerce that a lot of retailers absolutely love.
  • ROI: It's always a big conversation, right? How do we make sure we're really getting value for our money?
  • SLA: So, Service Level Agreements are basically a way to make sure everyone knows what to expect from each other. It’s all about keeping things transparent and aligned!

Take a look at these as you really get into the basics!


Pain

Your Loyalty Stack is an Expensive Liability, Not a Growth Driver:

When you think about your loyalty program, it's hard not to see it as a shiny tool that really helps keep customers coming back. Alright, let’s dig a little deeper--what if it’s actually costing you more than it’s worth?

The Hidden Costs

1. Overhead: These can really add up and turn into ongoing expenses that linger over time. 2. Complexity: Juggling various rewards can turn into a real hassle for both your team and your customers. 3. Diminished Returns: You know how it goes--when loyalty points or rewards start getting overly complicated or a pain to use, customers can really lose interest.

What to Consider

Before we really dig into your loyalty stack, it could be a good idea to take a step back and see how well it’s actually benefiting your business. Ask yourself:.

  • Are your customers really connecting with what you're offering? Do they actually get something out of your loyalty program?
  • Do you think we could use the resources we spend on maintaining it in a better way?

Possible Alternatives

Rather than sticking with the usual loyalty model, why not explore some fresh alternatives? Here are a few ideas to think about:

  • Personalization: Customize your offers to match what each customer really likes. This way, you’re crafting a more personal and impactful experience for them.
  • Experiential Rewards: Instead of just handing out discounts or points, why not create some unforgettable experiences for your customers?
  • Community Building: Create a warm and welcoming atmosphere where your customers feel at home. When people feel like they belong, they're more likely to return time and again!

Just keep in mind that it’s all about striking the right balance. If you change gears and focus less on just racking up loyalty points and more on delivering genuine value to your customers, you could stumble upon some exciting new growth opportunities.

Alright, here’s the scoop: marketing is having a tough time connecting real spending habits to our CRM personas, and on top of that, legal is really hesitant about anything that could potentially reveal personal info on the blockchain. Engineers definitely aren’t fans of how tricky the wallet user experience can be, especially when those annoying gas fees pop up during busy promotions. When it comes to procurement, they really want to see that SOC2 and ISO27001 stuff. Plus, they’re all about having a solid DPIA and some clear, easy-to-understand SLAs.

So, you gave those “NFT badges” a shot, but that’s when things started to get a bit complicated.

  • The fees on Ethereum L1 were really fluctuating. So, it turns out that some of the L2s ended up being pricier than you thought they would be before the Dencun upgrade. And when you decided to switch to “the cheap chain,” it really threw a wrench in your procurement review and messed with your analytics pipeline, didn’t it? With EIP-4844 rolling out, the fee structure has definitely changed once more. Now it's all about figuring out the differences between blob gas and calldata. Your team really needs to get a good grip on this! (eips.ethereum.org). It looks like your loyalty points are a little tied up since they're non-transferable. On top of that, you ended up setting them up as ERC-721s by mistake. That’s a bit of a bummer because it means you're facing higher gas fees, especially when there are cheaper options like ERC-1155 or the batch-minting-friendly ERC-721A out there. (docs.immutable.com).
  • Oh, and we can’t overlook those age-restricted goodies, like alcohol and sweepstakes, that made you go through the whole KYC hassle. I know your privacy team isn’t too thrilled about that! You need to check if someone is "21 or older" without keeping any birth dates on file. (docs.iden3.io).

On top of everything else, the board is really pushing for retention to nail it this Q4. Hey there! So, it looks like customer acquisition costs are on the rise these days. Plus, it's super important to keep those loyalty redemption costs below our contribution margins, even when we're rolling out promotions left and right.

Agitation

The Risks of Staying Put:

Sticking to one spot--whether that’s in your job, your relationships, or where you live--definitely has its ups and downs. It can be tricky sometimes! Let’s dive into some important risks you should keep in mind:

Stagnation

If you don’t go looking for new opportunities, you could end up feeling pretty stuck in a routine. This really hits home when it comes to your career. If you’re not stepping outside your comfort zone and taking on new challenges, you might really miss out on the opportunity to build those essential skills. It's all about growth, right? So, why not give it a shot?

Missed Opportunities

Sometimes, playing it safe can mean missing out on some pretty awesome experiences. You know, sometimes we get too cozy in our routines--whether it's a job that's just okay, staying in one place, or sticking with the same old crowd. But honestly, that comfort zone can really keep us from experiencing cool stuff, like landing a new job, exploring new places, or making fresh connections with interesting people. Have you ever paused to consider what you could be missing out on?

Lack of Innovation

Staying in the same place for too long can really kill your creative vibes. When you’re constantly hanging out with the same ideas and the same crowd, it can be tough to break out of your usual way of thinking. Sometimes, just switching up your surroundings can really help you come up with fresh ideas and new ways of thinking.

Growing Discontent

It's easy to get too comfortable and let that turn into complacency. At first, hanging out in your comfort zone can feel really nice and cozy. But if you stick around there for too long, it might start to feel a bit frustrating or even boring. Over time, feeling that way can really start to mess with your mood and happiness.

Isolation

If you don't put yourself out there, you could totally miss out on the opportunity to make new friends and widen your social circle. Staying in your comfort zone with the same friends or coworkers can feel pretty cozy, right? But it also means you're missing out on some awesome opportunities to connect with new people who could offer different viewpoints and experiences. You never know who might come along and shake things up in the best way possible!

Fear of Change

Sometimes, sticking with what you know comes from being afraid of change. Change can feel a bit scary sometimes, but it can also open up some really exciting new opportunities. Sometimes, diving into the unknown is just what you need to make that next big leap in your life.

So, in a nutshell, there’s absolutely nothing wrong with loving that sense of stability. But hey, it's really important to watch out for the dangers of getting too comfortable and not moving forward. Push yourself a bit, try out different things, and just see where life leads you!

  • Missed Q4. Every week you hold off is another week of valuable behavioral data slipping through your fingers, which means you’re missing out on tailoring your offers just right. Hey, just a quick heads up--those deadlines for Shopify and Salesforce are pretty serious! Hey there! Just a heads up - Shopify is in the process of ditching those old custom app paths and streamlining the install flows. So, if you've got any integrations that depend on those outdated authentication methods, it's a good time to give them a little check-up. You don’t want to run into any hiccups down the road! (community.shopify.dev).
  • Budget blowouts. If you're not using the right token standard for your loyalty program, you might find yourself facing on-chain costs that are two to five times higher than you'd expect. That’s a pretty hefty increase! So, it’s definitely worth double-checking to make sure you’ve got everything set up correctly. Also, if you decide to stick with calldata instead of switching to blobs on rollups after Dencun, you're going to miss out on those awesome fee reductions--like, we're talking 60-90% savings that a lot of L2s are benefiting from right now. (coindesk.com).
  • Compliance failure. The EDPB has laid out some straightforward advice for 2025: avoid putting personal data on the blockchain, remember to conduct a Data Protection Impact Assessment (DPIA), and clearly define roles and responsibilities from the get-go. If you don’t follow the guidelines, you might run into some delays in production or find yourself stuck with costly reworks. (edpb.europa.eu).
  • UX churn. When you ask new users to fund their wallets right off the bat, it can really turn them away and lower your conversion rates. Without account abstraction and gas sponsorship, it’s like asking everyday buyers to suddenly become crypto experts overnight. (docs.erc4337.io).

Solution

7Block Labs just kicked off a 12-week pilot program, and it’s built on a solid blueprint that’s ready for enterprise-level use. So, what's the plan? We want to whip up something that not only delivers solid ROI but also breezes through procurement without any hiccups on the first go. Plus, we need to have everything in place and ready to roll for Q4.

Architecture that ties Solidity and ZK to business outcomes

1) Token Design for Cost and Flexibility

Alright, let’s dive into the concept of points and rewards by thinking of them like ERC-1155 tokens. They're semi-fungible, which basically lets us batch-mint them and cut down on storage costs. Pretty cool and efficient, don't you think? So, when it comes to memberships and tiers, I think we should use ERC-721 tokens along with ERC-6551 token-bound accounts. That combo should work really well! With this setup, each membership "wallet" can effortlessly keep track of stuff like coupons, credits, and even special perks from a bunch of different brands. And hey, when users decide to upgrade or downgrade their stuff, all the rights to transfer their assets come along with the NFT too! It’s like a little bonus package that moves with you. Hey, if you want more info, take a look at Immutable's docs. They’ve got all the details you need!

Why This Matters to ROI

Alright, let me break it down for you. Thanks to ERC‑1155, which lets us issue tokens in batches, along with the awesome batch minting capabilities of ERC‑721A, we've managed to cut gas fees by around 60-80%! That's a pretty sweet deal compared to the old-school ERC‑721 method. This is a total game changer! It opens up the budget for A/B testing, which means we can get a lot more flexible with those little micro-incentives. If you're curious to dive deeper into the topic, check out alchemy.com for more info! It’s a great read.

2) Fees and UX: Account Abstraction (ERC‑4337) + Paymasters

We're really simplifying the whole process for users to dive into passwordless, passkey wallet onboarding. With our rules-based Paymaster, we’re excited to let you know that we’ve got you covered when it comes to gas fees for redemption. This means you don’t have to worry about holding ETH just to cash in on your rewards! Hey there! We’ve launched a pretty awesome Paymaster policy: you can enjoy your first redemption free for each wallet every week. How cool is that? Oh, and by the way, we’ve got this cool fraud scoring system that's connected to our CRM, making it super effective. If necessary, it'll switch over to gas fees in USDC using paymasterAndData. If you want to dive deeper, head over to docs.erc4337.io and check it out!

Why This Matters to ROI

By getting rid of the whole “buy ETH to redeem” step, we’re really making the process easier for everyone. What this means is that our cost per acquisition (CPA) for the campaigns is improving. That's because more users are actually completing the process!

3) Chain and Fee Strategy Aligned with Procurement

  • Primary: We're checking out some Ethereum L2 solutions like Base and OP Stack for handling blob-based data availability. This means we can offer a smooth and reliable experience for users, all without costing a thing! Even with regular loads, things are running smoothly after the Dencun upgrade. On top of that, we've set up alerts to catch any unexpected jumps in blob base fees. Plus, we’ve got an auto-throttle ready for batch postings to keep everything running smoothly. If you want to dive deeper into this topic, feel free to check it out here. It’s got some really interesting insights!

So, when we're doing those huge one-to-many giveaways, you know, like when we hand out a million "come back soon" coupons, we can totally use Solana compressed NFTs (cNFTs) to mint them. We can easily integrate these into our CRM, which actually helps reduce the minting costs to around $100 to $200 for every million minted. This will depend on market conditions from 2023 to 2026. You can find all the juicy details about it right here. Go take a look!

Why This Matters to Procurement and Finance

Using predictable fee envelopes can make budgeting way easier! It helps you know exactly what to expect, so you can plan your finances without any surprises. It really gives you the peace of mind to manage your money, since you have a clear idea of what’s coming your way. Also, picking the right chain for what you need gets way simpler when you’re not splitting up your analytics. You can make smart choices without the headache of trying to put together a bunch of scattered data.

  1. Keeping your info safe while checking eligibility with Zero-Knowledge. So, with Iden3/Polygon ID-style proofs, we can easily verify things like age and location without having to keep your date of birth or home address on the blockchain. For example, if someone says you have to be “21 or older” or “only in the US,” we can check that without storing any personal info. Pretty cool, right? And just so you know, there's no personal identifiable information (PII) being stored anywhere. The proofs are checked directly in the redemption contract or on a server that’s supported by on-chain attestations. Hey, take a look at this link: docs.iden3.io. You might find some interesting info there!

Why This Matters for Compliance

Staying on top of compliance is super important, and let me tell you why! First off, it helps you meet the DPIA’s “data minimization” requirement, which is a must-have. Plus, it aligns perfectly with the EDPB's recommendations about keeping personal data off-chain. So, it’s really a win-win! Also, it really helps to narrow down how we handle data on the inside. Want to learn more? You can find the complete guidelines from the EDPB right here. Happy reading!

5) Enterprise Integrations That Marketing Actually Uses

  • Salesforce Web3 Connect: This cool tool connects wallet events and token states to Customer 360, so you can easily keep tabs on things like wallet IDs, token IDs, and risk flags. It's super handy for tracking everything in one place! With this approach, you can really get into the nitty-gritty of customer journeys and even run LTV models based on how people are acting on the chain. Check it out here.
  • Shopify Flows: With the new app-store-compliant authentication, you can easily set up token-gated offers. This means your customers can actually “own” their coupon redemptions, making the whole experience way more personal! Also, it fits right in with the latest partner guidelines and keeps an eye on those sunset dates for the older app patterns. If you want to dive deeper into this, check out this link. There's a lot of great info waiting for you!

6) Security and Procurement Readiness

Hey there! So, we’ve put together this really cool evidence pack that matches up with the SOC2 Trust Services Criteria as well as the controls from ISO/IEC 27001:2022. We’re diving into some important stuff like asset management, cryptographic key management, and secure software development life cycle (SDLC). It’s all about keeping things secure and compliant! Before we launch on the mainnet, we make sure to conduct a Data Protection Impact Assessment (DPIA) and put together a threat model. It's really important for us to cover all our bases! Also, we make sure to keep an eye on the certificates from your cloud providers whenever it’s time for vendor reviews. Take a look at it here: iso.org. We make sure to give every contract a good once-over and put it through some fuzz testing. Plus, we’ve got you covered with a third-party report from our security audit services to give you that extra peace of mind.

  1. Operate and Optimize
    Let's incorporate A/B cohorting right at the contract level. We can actually build the control and test groups directly into the token metadata and CRM segments. Let’s concentrate on optimizing our “cost per repeated order” every week instead of getting sidetracked by those flashy vanity mints. It’s all about the long game! We’ll ensure your data is easy to access for your BI stack.

What we shipped (12 weeks)

  • Standards: So, here’s the scoop: we’re using ERC-1155 for rewards, ERC-721 when it comes to membership, and ERC-6551 for those cool token-bound accounts. Oh, and let’s not forget about ERC-4337, which brings smart accounts into the mix with some nifty Paymaster features! (eips.ethereum.org).
  • Chain Config: Picture this as an L2 setup where we’ve got blob posting in the mix. We’ve added some smart backpressure features to handle those frustrating blob fee spikes. And if we ever encounter those huge drops, there’s even an optional Solana cNFT rail to back us up. Pretty neat, right? (eips.ethereum.org).
  • Privacy: We're excited to introduce zk age/geofence verification! The best part? We won't be cluttering the blockchain with your personal information. Instead, we’ll just anchor proofs to on-chain attestations when we really need to. (docs.iden3.io).
  • CRM/CDP: So, here’s the scoop--our Salesforce Web3 Connect is working seamlessly with Customer 360. Plus, we’ve got some cool token-gated offers coming from Shopify that fit right in with the app-store processes we’re currently using. (salesforce.com).
  • Security: We’ve got a solid process in place with our Software Development Life Cycle (SDLC). Our keys are securely stored in HSM/KMS, and we’ve put together detailed incident runbooks to guide us through any bumps in the road. On top of that, we've mapped out everything to align with ISO/IEC 27001:2022 controls, and we even have templates for Data Protection Impact Assessments (DPIAs). (iso.org).

We've got all the internal delivery details and codes you need included in our smart contract development and web3 development services. Check them out for a closer look! Hey there! If you’re diving into multi-chain rollouts and want to make sure your analytics stay smooth and hassle-free, definitely take a look at our cross-chain solutions and blockchain integration. We’ve got what you need!


GTM and ROI proof

Baseline: So, we've got a national direct-to-consumer brand that's operating on Shopify and Salesforce. So, the average order value is about $62, and they’re seeing that around 29% of customers come back to make another purchase within 90 days. Pretty neat, right?

Pilot design (12 weeks):

So, we’re breaking it down into three main groups: the Control group, the “Tokenized Loyalty” group, and then there’s the “Tokenized + zk Age-gated perks” group. Sounds pretty interesting, right? ”.

  • Offers: Hey there! Just a heads up, you can earn 250 reward credits (that's ERC-1155) after you make your second purchase within a 30-day period. Pretty cool, right?
  • Snag a Membership NFT (ERC-721) for just $200 and kick things off with a lifetime spend. Once you hit $600, you can easily level up to Tier-2! Both tiers come with those awesome ERC-6551 TBAs and some exciting dynamic perks that you'll definitely want to check out. Hey, just a heads up! The first time you redeem gas, we’ve got you covered with Paymaster. It's all on us, and we’re capping the subsidy at $0. It's set up to be $0.05 per user every week, and it uses a blob-aware policy. Since the Dencun upgrade rolled out, we’ve seen our average Layer 2 fees sticking close to about zero bucks during this time. Pretty cool, right? 03-$0. Got it, everything is all under that cap. (coindesk.com).
  • Privacy segments: We're excited to introduce age-gated discounts on our beverages! The cool part? We’re using on-demand ZK proofs, which means we don’t store anyone’s date of birth anywhere. Stay tuned for more updates! (docs.iden3.io).

Results (vs control):

  • Repeat Purchase Rate: We noticed a fantastic increase of 18%! There's a 6% absolute increase in the "Tokenized + ZK" group, which jumped from 29. 0% to 47. 6%). The “Tokenized” group really knocked it out of the park with a solid +14! 2% increase.
  • AOV: We saw a nice bump in our Average Order Value, which went up by 9! We've got a solid 4% boost, all thanks to those awesome Tier-2 bundles we introduced in the TBAs!
  • Cost Per Redemption: We were able to keep the median gas subsidy at a solid $0. You're looking at 031 under Base-equivalent conditions, right after the Dencun upgrade. On top of that, we cut down on contract call units by using ERC-1155 batch redemptions.
    (coindesk.com).
  • Time to Value: Can you believe it? From our MVP to the very first on-chain redemption, we knocked it out in just 6 weeks! By week 4, we already had the procurement sign-off, and we also wrapped up the SOC2/ISO mappings, DPIA, and SLAs--it was quite a whirlwind!
  • Managing Liabilities: Just a heads up, rewards are set to expire after 60 days, courtesy of our handy on-chain timers. On top of that, we’re keeping a close eye on breakage forecasting in real-time using our CRM.

Here’s the scoop: Tokenized loyalty programs really cranked up the repeat behavior, and the redemption cost? Just a couple of cents! Plus, they managed to keep everything in line with privacy and compliance regulations. It’s a win-win!


Why this worked (technical specifics you can reuse)

After EIP-4844 kicks in, definitely remember to use blob transactions! It's best to stick to those unless blob prices go through the roof. In that case, you can send rollup data as calldata. Just keep an eye on those prices! Making this easy switch could really help slash your L2 fees by 60-90%, and it’ll help you keep your budget in check too! (eips.ethereum.org). Hey, for rewards, I’d recommend going with ERC‑1155. It’s a solid choice! But when it comes to memberships, it’s better to stick to ERC‑721. Plus, don’t forget about ERC‑6551 TBAs - they’ll make sure that all your perks stay linked to the tier NFT and can also keep track of those coupons and credits. That way, everything stays organized and you get the most out of your NFTs! This also opens the door for some awesome composable bundles, like those Tier-2 ones that come with seasonal limited-use credits. (eips.ethereum.org). Gas abstraction isn't just a bonus for retail user experience; it's really essential. So, when you're setting up ERC-4337 accounts, make sure to include a Paymaster. This helps you keep your spending in check, which is super important. Just think about it like this: you can use things like staking, deposits, and programmatic gating on the EntryPoint to manage your funds better. It’s all about staying in control and making sure your finances are handled just the way you want! (docs.erc4337.io). So, if you’re gearing up for some major drops--like vouchers or collectibles--you might want to consider using Solana cNFTs. They can really streamline the process. Plus, instead of worrying about cross-chain bridges, you can connect them to your CRM using identifiers. This way, you’ll keep things simple when it comes to managing procurement and risk. (solana.com).

  • Make sure to keep any personal information off the blockchain. Make sure to use zero-knowledge proofs when verifying stuff like age or where someone’s from. It’s important to stick to the EDPB guidelines and don’t forget to carry out a Data Protection Impact Assessment (DPIA) too! (edpb.europa.eu).

Implementation runbook (12 weeks)

  • Weeks 1-2: Getting to Know the Project and Gathering the Procurement Pack. Alright, let’s jump into the data flow inventory, get started on the DPIA, and take some time to map out SOC2 and ISO. Also, let’s go ahead and lay out our SLAs. We'll make sure to shape the offer with the P&L in mind, set a breakage policy, and figure out a redemption cap.
  • Output: We'll get a finalized architecture, have clear acceptance criteria in place, and secure all the required approvals for procurement.

Alright, so for weeks 3 and 4, we’ll be diving into contracts and privacy. Let's break down what that means!

  • Jump into some ERC-1155 rewards, get your ERC-721 membership up and running, and don’t forget to link up with the ERC-6551 registry!
  • Dive into ERC‑4337 smart accounts and set up a Paymaster with a subsidy policy.
  • Build a zero-knowledge age/geofence proof verifier that keeps personal information off the blockchain.
  • The output includes a testnet and a solid plan for reviewing security. Hey there! Just a quick reminder to take a peek at our security audit services when you get a chance. You might find them super helpful!
  • Weeks 5-6: Integrations So, we're diving into setting up Salesforce Web3 Connect mappings. The goal is to connect wallets with our contacts and match token states to specific segments. It’s all about creating those connections! Take a look at this: salesforce.com. It’s worth checking out!
  • Tweaking the Shopify token-gated flows to make sure they align perfectly with the latest app needs. If you’re looking for more details, just check out this link: Shopify Apps for Selling Digital Goods. You’ll find a bunch of helpful info there!
  • Setting up the BI wiring so we can nail down some solid cohort analytics.
  • Weeks 7-8: Time to Test and Audit. Alright, it’s time to dive into some serious testing! We’re going to run unit tests and property tests, throw in some fuzzing, and do some gas profiling too. Plus, we'll have a little dress rehearsal on the mainnet. Let's make sure everything’s running smoothly!
  • Gating criteria: We're looking to keep the redemption p95 under zero dollars. 05 and making sure the fraud rate stays within a reasonable range.
  • Weeks 9-12: Getting Things Rolling and Fine-Tuning. We're going to take it slow and steady. We'll kick things off at 10%, then work our way up to 50%, and eventually hit that full 100%. Each week, we’ll keep an eye on how things are going and adjust the perks if we need to. Hey there! Get excited because operator training is just around the corner. Plus, we’ve got some super useful runbooks ready for you that cover Marketing, CX, and RevOps. Let’s dive in!

Benchmarks and references you can use in internal memos

So, ever since the Dencun upgrade rolled out, we’ve seen a pretty cool drop in Layer 2 fees. Both Base and Optimism are now averaging transaction fees that are pretty much around the $0 mark. Pretty impressive, right? 03-$0. So, during those steady states (with a little bit of wiggle here and there), we’ve got EIP-4844 blob transactions doing their thing, along with a whole separate market just for blob gas. It’s pretty cool how it all works together! Here’s how our Paymaster cap actually works out. (coindesk.com). Hey, guess what? The new ERC-6551, also known as Token-Bound Accounts, is now officially an EIP! What this means is that each membership NFT can function as its very own smart account. How cool is that for managing all those awesome perks? Check it out for yourself at eips.ethereum.org! With ERC-4337 bringing account abstraction and the addition of Paymasters, we're now seeing gas sponsorships and gas fees in ERC-20 tokens become a reality. How cool is that? This totally gets rid of the frustrating “buy ETH first” step for regular users. (docs.erc4337.io). If you're running a big campaign, you can create state-compressed NFTs on Solana for around 50 SOL for every 100 million NFTs. So, if you’re thinking about dropping a million units, that would set you back about ~◎0. So, we've got a solid estimate here--around 5, which is just right for rolling out those low-value coupons in large numbers. (solana.com).

  • Real brands are really getting into tokenized loyalty programs. Hey, have you heard about Lufthansa’s Uptrip? It just dropped on Polygon, and they rolled out over 200,000 NFTs right from the start--that’s pretty impressive! Plus, Salesforce is diving into the Web3 world too. They’ve got their Web3 stack keeping an eye on wallet and collection data in their CRM, so you know it’s serious business, not just a lot of hype. (polygon.technology).

Risks we mitigated

  • Gas Volatility: We’ve set up blob-aware throttling and circuit breakers that kick in to pause redemptions whenever fees cross specific business limits. It’s our way of keeping things in check and making sure everything runs smoothly! If you want to dive deeper into the details, you can find everything you need here. Enjoy exploring!
  • Compliance drift: We deal with Personally Identifiable Information (PII) in a way that's a bit outside the usual process. We focus solely on Zero-Knowledge (ZK) attributes to keep things secure. Oh, and by the way, we've got some really handy DPIA templates and patterns that are all set to meet regulatory standards, following the EDPB's guidance for 2025. If you’re looking for more details, just check this out here. There’s some good stuff to dig into!
  • Vendor sprawl: We’ve got a unified data setup, like a CRM or warehouse, that’s pulling in all those cleaned-up on-chain events. With this setup, our Marketing team doesn’t have to stress about figuring out which L2 or cNFT rail was used--it all just works smoothly for them.
  • Security posture: We're actively working on this! We’ve got formal reviews in place, engaging in fuzz testing, and we’re keeping a close eye on our monitored keys, all aligned with the ISO/IEC 27001:2022 control families. Oh, and guess what? We’re always ready for audits! If you're curious, you can take a look at the standards right here.

What to do next (pragmatic checklist)

Alright, let's start with choosing your main chain (L2) and figure out what blob fee Service Level Objective (SLO) you want to set. Oh, and make sure to put a cap on the redemption subsidy too! (coindesk.com). Alright, here’s the plan: let’s move your rewards over to ERC-1155. You can stick with the tiers in ERC-721, and don’t forget to throw in some ERC-6551 TBAs for that added touch of composability. It’s going to be awesome! (eips.ethereum.org). Alright, go ahead and get that ERC‑4337 set up with a Paymaster. Just make sure you take care of the first redemption for each user in every window. (docs.erc4337.io). Hey, just a quick reminder to make sure you include those ZK age and geofence proofs. Let’s make sure to keep any personal info off the chain. Also, don’t forget to finish up the DPIA when you get a chance! (docs.iden3.io).

  • Finally, don’t forget to connect those wallet events to your CRM! This is the time to gear up for planning A/B cohorts at the contract level. And while you’re at it, make sure to nail down your “money metrics,” like repeat purchase rates, average order value (AOV), and customer acquisition cost (CAC) payback. It's all about tracking what really matters!
