The Specific Technical Headaches Killing ROI

So, your L1-first proof of concept definitely showed promise, but it seems like every time you try to increase the transactions per second (TPS), your cloud bill on the Ethereum mainnet ends up going through the roof. You know, sometimes even the easiest changes can end up costing a lot more than you'd think. And let's not even get started on those batching windows--they're pretty delicate! CFOs are really just noticing the ups and downs of those fees, instead of focusing on the real value behind it all. Absolutely, L2s definitely provide some breathing room, but if your setup is still sending data as calldata, you're really missing the boat on the blob fee market. Take a look at this: l2fees.info.

• It seems like your Solidity codebase is hanging on to some old habits, like it's from a time before Dencun even rolled around. It looks like you're missing out on using MCOPY for those big memory moves, and you might not be using transient storage to keep your inter-frame state safe from reentrancy issues. Also, those assumptions about deploying or upgrading during the SELFDESTRUCT era? Honestly, that's pretty old school. Check out all the details right here: (eips.ethereum.org). You won’t want to miss it!

Let's be real--when it comes to identity and signing in, it's pretty chaotic out there. Honestly, mobile passkeys (P-256) and enterprise SSO really aren’t doing the trick for energy-efficient on-chain authentication processes. Account abstraction (AA) kind of comes off as an afterthought rather than something that's been thoughtfully designed from scratch. Procurement is definitely raising some eyebrows and calling this an “unfamiliar risk.” "Want to dive deeper? Check it out here: (eips.ethereum.org)."

"Private compliance" feels more like a concept you’d see on a presentation slide rather than an actual, well-established system. So, it turns out that KYC (Know Your Customer) and AML (Anti-Money Laundering) checks are accidentally spilling personal info into the operations process. Plus, verifiers are really in the market for solid proof, instead of just relying on the usual documents. It seems like your teams are having to redo the same checks for every different jurisdiction, which can be super frustrating. Dive deeper here: (docs.privado.id).

Oh, and we can't overlook the security sign-off process--man, it's such a drag and takes forever! So, the auditors are looking for some pretty specific stuff like artifacted tests, those static analysis baselines, and results from property-based fuzz testing. Meanwhile, the engineering teams are just sending over screenshots. It's quite the mismatch, isn't it? On top of that, gathering SOC 2 evidence can be quite a hassle. It’s definitely a tedious manual process that takes a lot of time and effort. Check this out: (github.com).

The Enterprise Risk You Can Quantify

• Missed deadlines: Ignoring Dencun primitives can really set you back--you're looking at spending 5 to 10 times more just to achieve the same throughput. This can squeeze your feature budgets and leave you struggling to meet your quarterly goals. These days, blob-backed L2 batches have really become the standard. You know, those old beliefs we had back in the calldata days just don’t cut it anymore when it comes to RFP cost models. (blog.ethereum.org).
• Compliance drag: You know, procurement can really hit a wall if they don’t have SOC 2-aligned runbooks in place. We’re talking about essentials like change control, deployment approvals, SIEM hooks, and the necessary evidence. It’s like trying to navigate a maze without a map! Also, if you haven’t figured out a way to minimize data collection--like using zkKYC, passkeys, or single sign-on--you might be in for some pretty long delays. We're talking about waiting through several quarters and dealing with a pile-up of questionnaires. (aicpa-cima.com).
• Architectural lock-in: If you’re hanging onto those ancient SELFDESTRUCT-era “metamorphic contracts,” you might want to brace yourself because they’re going to face some challenges with the new EIP-6780 semantics. Addressing these problems at the last minute can really throw a wrench in your CI/CD processes, audits, and vendor SOWs. It’s like a domino effect, and suddenly everything starts to feel a bit chaotic. (eips.ethereum.org).
• ZK cost cliff: So, when it comes to verifying those raw, per-user proofs on-chain, you could be looking at over 200k gas to get it done. That's quite a hefty price tag! Now, if you think about that happening a million times each month, your so-called “privacy feature” might start feeling like a major expense instead. We’ve got aggregation in the works, but it's not fully up and running just yet. (hackmd.io).

7Block’s Down-to-Earth Approach to Boosting ROI

At 7Block, we like to start things off by zeroing in on real, measurable savings instead of just churning out new features for the sake of it. We’re all about making things easier! We’ve lined up our code paths with some cool new protocol features, combined Zero-Knowledge (ZK) tech with aggregation economics, and wrapped it all up nicely. This means that getting what you need for your business is a total snap!

1) Platform fit: L2 and DA selection driven by blob math, SLAs, and identity support

• If you're trying to save some cash on batch data expenses, consider checking out blob-backed L2s. So, EIP-4844 has been live on the mainnet since March 13, 2024! Just a quick heads-up: those blobs? They get pruned after roughly 18 days. It's really important to keep the blob fee market in mind when designing, rather than just zeroing in on calldata. It definitely makes sense to adjust your transaction mix according to the latest L2 fee tables--like when you're sending and swapping on those big rollups. Take a look at this: blog.ethereum.org. You won’t want to miss it!

If you’re in a situation where you need passkeys, the OP Stack chains are definitely the way to go! The P256VERIFY (RIP‑7212) located at 0x0100 allows you to easily handle native secp256r1 verification. What it means is that you can easily incorporate WebAuthn into your on-chain processes using Account Abstraction (AA). If you want to dive deeper into the details, check it out here: specs.optimism.io.

If you're working with bridges or handling staking data, make sure to check out EIP‑4788's Beacon Roots contract. It can really come in handy! This super handy ring buffer, which holds 8,191 roots, is great for providing trust-minimized consensus proofs in the EVM. This is a fantastic way to avoid relying on outside oracles, which helps keep your staking, bridging, and restaking setups running without a hitch. Want to get the inside info? Check it out here: (eips.ethereum.org).

2) Gas-first Solidity: Compile- and Opcode-Level Savings You Can Bank

• Give a modern version of solc a go! It comes with via-IR and optimized runs that you can tweak to fit your specific needs. If you're looking for something reliable and substantial, the IR/Yul pipeline is definitely the way to go. We set specific versions for each environment to keep things consistent, and we ensure that every optimizer run in CI is reliable and predictable. Check out more here.

Hey, don't overlook MCOPY when you're handling bulk memory tasks, especially if you're working with things like parsers or Merkle proofs. It's a real game changer! Usually, the cost breaks down to around 15 plus 3 times the length divided by 32 in gas fees. Don't forget about any additional expansion costs, but generally, this method tends to be more cost-effective than coding your own loops. If you want to dive deeper into the details, just check this link out here. It's a great resource!

Let’s move away from those old habits of writing first and then refunding! Instead, why not switch to using transient storage like TSTORE and TLOAD? They’re great for keeping your reentrancy guards in check, managing transaction allowances, and making sure everything flows smoothly within the frame. Give it a try! This way, you can dodge those pesky costs that come with constant SSTORE overhead and the annoying refund limits. If you want to dive deeper into it, you can check it out here.

• Hey, let’s try to steer clear of using SELFDESTRUCT for upgrades now that Dencun has put some limits on it, only allowing it for “create-and-destroy-in-same-tx.” "Instead, try using minimal proxies and controlled upgrade beacons instead." Just be sure to back up your assumptions with some good testing. It's really important! If you want to dive deeper into the topic, you can check out more details here.

3) Account Abstraction that Procurement Understands

• Begin using ERC-4337 smart accounts along with paymasters. And if necessary, throw in some signature aggregation (ERC-7766) to ease the validation process for users. Hey, just a heads-up! The EntryPoint has been live since March 1, 2023, which means account abstraction has officially moved past the "experimental" phase. It's now fully operational and ready to go at scale! Hey, if you’re curious, take a look at it over on ethereum.org. It’s worth a peek!

To make things super easy for users in companies, you should mix Single Sign-On (SSO) and SAML at the web level with some passkey support for account management--using P-256 on OP chains, of course. Oh, and why not add some optional spending controls with session keys for an extra layer of security? It’ll really streamline the experience! This creates a "passwordless" experience, so you won't have to worry about using a custodial wallet. If you're looking for more info, just check out specs.optimism.io. It's all there!

4) ZK You Can Afford: Aggregate or Skip It

Hey there! So, rather than going through and checking a million Groth16 proofs one at a time, why not keep it straightforward? If you just run one on-chain Groth16 verification, it’ll only set you back about 207,700 plus an extra 7,160 for each public input you have. Easy peasy! I get it--when gas prices are even just a little high, those costs can add up quickly. It makes a lot more sense to gather all the proofs off-chain first and then just settle one big super-proof on-chain. So, usually, you’re looking at a base cost of about 380,000 gas, and then you’ll need to budget an extra 16,000 gas for every inclusion check you do. So, by doing it this way, instead of each proof racking up over 200k in gas fees, you can actually bring it down to just a few tens of thousands altogether. Pretty neat, right? If you want to dive deeper into the details, just click here. Happy exploring!

When you're diving into KYC and AML stuff, it's a good idea to use verifiable credentials paired with zk attestations, like the Privado ID, which is also referred to as Polygon ID. The best part? The verifier just looks at the proof and never actually gets to see any of your personal info. Pretty cool, right? Not only does this breeze through privacy reviews, but it also helps eliminate those annoying repeated vendor checks. If you want to dive deeper, just check this out here.

5) Compliance by Design: SOC 2-Ready Pipelines

First things first, take some time to map out your CI artifacts. Think about things like static analysis, fuzz testing, coverage reports, gas snapshots, and deployment diffs. You'll want to line these up with the evidence requirements for SOC 2. This will help ensure you're on track and have everything in place! When it comes to security, that's definitely non-negotiable! But if it makes sense for your project, don't forget to think about how available the information needs to be and the importance of keeping it confidential too. Hey, just a quick reminder to set up the automation for exporting this evidence into your GRC. It’ll save you a lot of time! If you want to dive deeper into it, you can check out more details here. Happy automating!

• Alright, let’s go ahead and get your security tools all lined up and standardized. When you're reviewing pull requests, try using Slither to dive into those static findings. It really helps you catch any issues. And for property fuzzing in your CI, you can't go wrong with Echidna. It’s great because it can generate JSON outputs, which are super handy as proof of your testing results. Make sure you don't miss out on those Foundry gas snapshots! They’re super important for keeping an eye on regressions and making sure everything stays on track. You can check out Slither right here.

6) Observability and SLAs

Hey, don’t forget to grab those metrics from the node and AA bundler! You’ll want stuff like latency, bundle success rates, blob inclusion, and reasons for any reverts. Make sure to send it all directly to your SIEM. It'll help keep everything in check! If you keep tabs on contract-level telemetry, you can spot those blob market spikes and potential paymaster balance issues before they turn into a real hassle for users.

Claims Processing DApp: L1→L2 with Blob-Native Batching

• After: So, we used to post batches as calldata on L1, and honestly, it was a real pain. Those fluctuating fees were a nightmare, and our budget felt like it was spiraling out of control every week.
• After: We've moved our settlement over to an OP Stack L2. This way, we can use those EIP‑4844 blobs, which get cleared out after around 18 days. Oh, and guess what? We completely overhauled our batch encoder to make it way better at packing those 128-KB blobs. It’s pretty cool how much more efficiently it works now! We replaced the in-contract copy loops with MCOPY to take care of pre-hash staging. Plus, we're now utilizing transient storage for those single transaction approvals. So, what's the result? We've noticed a big drop in the costs per batch for DA, and those annoying outliers during fee spikes are happening a lot less often now. Right now, our operator spending is pretty consistent and easily passes the CFO's reviews. (ethereum.org).
• Measurement: So, if we check out the latest L2 fee tables, we're seeing them sitting around $0. 05-$0. If you're sending or swapping stuff, it usually costs around $20, depending on the blockchain you're using. By moving a flow of 5 million transactions per month from posting to calldata to using blobs instead, you can really cut down those data availability costs by a significant amount. Sure thing! Just keep in mind that your exact rate can fluctuate depending on the blob market conditions. But no worries--we’ll monitor it closely and adjust as needed to protect your interests. (l2fees.info).

Passwordless Enterprise Portal with Private Eligibility Checks

• After: We used to depend on OAuth and then go through KYC documents manually, which honestly just made things super busy for our helpdesk team. On top of that, we also had to deal with some privacy worries from our InfoSec team.
• After: So, we’ve made the switch to WebAuthn passkeys (P‑256) which now verify on an OP chain using the P256 precompile. So, here’s the deal: our AA paymaster takes care of the fees for first-party users. We figure out who’s eligible based on a few factors, such as age, where you live, and your accreditation. To do this, we use Privado ID zk credentials. Pretty straightforward, right? The coolest thing? You won't have to worry about any personally identifiable information (PII) slipping into your backend or being stored on the chain. Verifiers simply look at the proofs--easy peasy! So, what's the end result? A way better experience for users and a solid legal footing. (specs.optimism.io).

ZK Settlement at Scale with Aggregation

• After: Each user proof had to be verified on the blockchain, and it was pretty pricey--like, around 200k to 300k gas each time! What this really meant was that as more and more users jumped on board, the operating costs could start to get pretty out of hand. (hackmd.io).
• After: So, guess what? We can now group thousands of Groth16 proofs into one big mega-proof, which means we only have to pay around 380k gas just one time. Pretty cool, right? So, whenever we need to tap into the app logic, it only costs us about 16k gas for each inclusion read. Not too shabby, right? For businesses that have to manage a ton of users, this change can really flip a "feature" into a major "cost center." ” (docs.electron.dev).

Emerging best practices you should adopt now

Whenever it’s possible, try to replace calldata posting with blob-native pipelines. Just a heads-up: when you're designing, keep in mind that blobs can sometimes end up being too saturated or not saturated enough. It’s a good idea to have a backup plan in your back pocket, just in case things don’t go as expected! Just a quick reminder to keep an eye on the blob fee distribution in your monitoring tools. It's important to stay on top of that! If you want to dive deeper into this topic, take a look at this link. You’ll find plenty of useful info there!

• It's time to let go of SELFDESTRUCT. If your plan for rolling out updates or changes involves deleting code in later transactions, it’s a good idea to start using proxy patterns immediately. Be sure to include this in your upgrade runbooks to keep everything consistent. If you're curious to dive deeper, you can check it out here. Happy reading!
• Consider MCOPY your best buddy for handling buffer operations, as well as managing trees or receipts. It's a solid choice! Hey, just a heads up--when Dencun drops, it’s time to clear out those old loop utilities. You’ll no longer need them! If you want to dive deeper into the details, check it out here.

Consider AA more like a key part of the platform instead of just an add-on. Let's stick with ERC-4337 wallets, bundlers, and paymasters. And wherever we can with the wallets, let’s also work on adding in some signature aggregation. If you want to explore this topic further, feel free to check it out here. There's a lot of interesting info waiting for you!

Right from the get-go, set up a zk credential lane to keep things compliant. Just a heads up: verifiers really care more about the actual proof rather than just paperwork. This will help you create a really engaging privacy story that’s easy for procurement to get behind. Check it out here.

GTM Metrics -- How This Appears in Your Board Deck

• Transaction Economics: If you switch to blob-backed rollups and throw in some simple gas engineering, you could see your data availability costs drop by around 10 times compared to those old-school calldata-era rollups. That’s a pretty sweet upgrade! Check out the latest fee tables, and you’ll see that sending and swapping on mature Layer 2s is now just a few cents! It’s pretty cool how things have changed. Alright, so when you're thinking about your operating environment, this is what you should keep in mind for your planning and pricing.
  (blog.ethereum.org).
• ZK Verification Spend: So, here's the deal: when we combine proofs, we can really cut down on those on-chain verification costs. Instead of shelling out around 200k-300k gas for each proof, we can bring it down to about 380k gas for an entire batch. That breaks down to roughly 16k gas per proof when you spread it out. Pretty neat, right? When you scale things up, you can often see improvements of more than 10 times! (hackmd.io).
• Procurement Velocity: When you've got SOC 2-ready evidence on hand--like static analysis diffs, fuzz reports, gas snapshots, and controlled release approvals--it can seriously speed up your security questionnaire process. Plus, it helps you dodge those frustrating “pen-test first” delays! (github.com).
• Product Conversion: Thanks to passkeys and AA paymasters, we’ve finally said goodbye to that annoying "buy ETH first" step. It’s so much easier now! On top of that, OP Stack P256VERIFY is a game changer for native mobile secure enclaves. It really lets users enjoy an enterprise-level experience without worrying about those pesky custodial risks. (specs.optimism.io).

How 7Block Labs Executes (And Where We Own the Outcome)

Strategy and Architecture

Let’s get started with a platform selection workshop--you know, something like L2, DA, or a bridge. During this session, we’ll really dig into blob fee modeling and make sure we’re on the same page about those SLA constraints. Sounds good, right? Next on our agenda, we're diving into the compliance posture mapping for SOC 2. We'll be figuring out who the control owners are, putting together a solid evidence plan, and getting our change control systems in place. Exciting stuff ahead! We’ve made sure that everything we deliver aligns perfectly with the RFP/SOW language. This means we’ve got all the bases covered when it comes to SLAs, escalation paths, and security scope.

Build and Optimize

We're all about using Solidity via-IR builds, and we actually apply MCOPY/TSTORE patterns for added efficiency. When it comes to gas management, we make sure to run gas snapshots as part of our CI process. Plus, we’ve got our backs covered with reentrancy guards that leverage transient storage. We usually bring in ERC‑4337 accounts that come with paymasters, optional signature aggregation, and OP Stack passkey integration whenever it feels right. Hey, if you're curious about the details of EIP-4337, give it a look! It's got some interesting info worth checking out. When it comes to ZK aggregation, we're all about using Groth16. This gives us reliable Layer 1 settlement economics, plus it provides clear audit trails and checks for inclusion. If you want to dive deeper into this topic, be sure to check out the Electron documentation. It's packed with useful info!

Assurance and Integration

We make sure our security is on point by using a mix of static and dynamic checks. We rely on Slither baselines and Echidna property suites, along with Foundry’s fuzz testing and gas regression gates. Plus, we’re all about keeping everything organized, so we export those artifacts straight to GRC. Hey, make sure to swing by Slither on GitHub when you get a chance! You won't want to miss it! When it comes to keeping an eye on things, we’ve got everything you need! You'll get access to bundler metrics, we’ll help you track blob fees, and you’ll receive alerts for paymaster balances--all seamlessly integrated into your SIEM. We've made it super easy for you!

Brief Technical Appendix (for your lead engineer)

Dencun specifics you should code for today:

• EIP-4844 blobs: So, we're talking about type-3 transactions in this case. Each blob can pack in a maximum of 128 KB, and we can fit up to 6 blobs in a single block. Just a heads-up, there's roughly an 18-day window where things will be available, and there's also a separate fee market that's a bit like 1559. So, keep that in mind! It's super important to tell the difference between blobs (DA) and calldata. You see, blobs are a bit more flexible, while calldata sticks around for the long haul--and it tends to cost more too. If you're curious and want to dive deeper into the details, just check this link out here.
• EIP‑5656 (MCOPY): This is the one you'll want for handling buffer moves and parsers. It's super useful! It'll save you some money on gas and help you clean up your code a little! Check it out here.
• EIP‑1153 (TSTORE/TLOAD): You can think of this as a fresh way to handle temporary SSTORE patterns. It’s like giving them an upgrade! You'll get more secure reentrancy locks and approvals for each transaction. Get the scoop here.
• EIP‑6780: So here's the deal: if you use SELFDESTRUCT now, it’ll only go through if you call it in the same transaction that created the contract. Make sure to tweak your upgrade strategies to reflect this change! If you’re looking for more details, you can check it out here.
• EIP‑4788: To get started, you’ll want to check out the Beacon Roots from 0x000F…Beac02, and don't forget to use an 8,191-slot ring buffer! This will give you a solid foundation for creating proofs for staking and understanding how bridge logic works. Dive deeper here.

Account Abstraction (4337) notes:

• The EntryPoint has been up and running since March 1, 2023, and it's already getting quite a bit of traction in the real world! If your budget allows, definitely take a moment to dive into JSON-RPC (ERC-7769) and aggregation (ERC-7766). It's worth checking out! If you're looking for more info, you can check it out here.

ZK Verifier Economics:

If you're checking out the BN254 Groth16 verifier, just a heads-up: the gas cost rounds up to around 207,700 plus an extra 7,160 for every unit 'l' you include. When you put everything together, it bumps the settlement up to roughly 380,000 gas for the base amount, plus about 16,000 gas for each inclusion call. Just remember to base your approach on your own style and rhythm. If you want to dive deeper into it, check it out here. You'll find some great info!

The 90‑Day Outcome You Can Expect

• Days 0-15: We’re going to get started by diving into platform and fee modeling. We'll take some time to outline the SOC 2 controls and really nail down the architecture with our choices for blob storage, AA, and ZK. It’s all about laying a strong foundation! During this phase, you can expect to receive a high-quality SOW/SLA pack that’s perfect for your RFP needs.
• Days 16-60: Alright, so here’s what’s coming up! We’re going to jump into setting up AA wallets and a paymaster. Plus, we’ll be exploring blob-native batching too. It’s going to be an exciting phase! We're going to dive into refactoring MCOPY and TSTORE, and at the same time, we'll be linking up zk credentials to create a seamless and impactful experience.
• Days 61-90: Alright, we’re finally diving into security! During this time, we’ll be using some cool tools like Slither, Echidna, and Foundry to beef things up. We'll take a look at our cost benchmarks compared to what we've set as our baselines. After that, we'll tie everything together by finalizing those observability metrics and getting all the procurement evidence sorted out.

If you're after a real return on investment that impresses both your engineering team and procurement department, we can easily integrate that into your contracts, ZK rails, and evidence binder.
