Summary: So, here’s the scoop: as we look towards 2026, the Web3 roadmap is really focused on a few key things. First up, we’re all about keeping costs low, especially after the Dencun and Pectra developments. Then there’s the whole regulatory landscape to consider--things like MiCA, DORA, Basel crypto disclosures, and the SEC rolling back SAB-121 are definitely on our radar. We also want to make wallets way more user-friendly, so keep an eye on ERC-4337 and 7702 for some promising updates. Last but not least, we’re stepping up our game in risk management with tools like OWASP SCSVS and EthTrust to help keep everything secure. Exciting times ahead! This guide is all about helping leaders choose the right tech stacks--think options like OP Stack, Arbitrum Orbit, and Hyperledger Fabric or Besu. We’ll also dive into how to set up pilots that truly track what counts, so you’re not just going through the motions. Plus, we’ll talk about how to kick off production programs with clear KPIs and a sensible budget in mind. Let’s get started!

Blockchain Strategic Planning Consulting and Consultants: How to Build a Web3 Roadmap

7Block Labs Viewpoint

As we peek into 2026, I really think the true winners in the digital asset world are going to be the ones who focus on well-structured, regulated, and budget-friendly programs. Let’s be honest--nobody needs another “blockchain tour.” It’s all about delivering real value and staying grounded in what matters. "Hey there! We’ve got a straightforward, standards-based method that we suggest to our clients for building a roadmap that everyone--from the executives to compliance teams and engineers--can really get on board with."

Why 2026 planning is different

Hey, have you heard about the Ethereum Dencun upgrade coming in 2024? It’s going to be a real game changer! One of the key features is EIP-4844, which introduces these cool "blobs." Thanks to this upgrade, rollup data costs are going to drop dramatically, making those sub-cent L2 fees a reality in many situations. Exciting times ahead for Ethereum! So, on May 7, 2025, Pectra launched some really cool updates! They made some nice improvements to wallets and validators, like those EIP-7702 and EIP-7251 enhancements. Super exciting stuff! These changes really mix things up in L2 economics and the trade-offs that come with user experience. Take a look at this: (blog.ethereum.org). You won’t want to miss it! Things are getting pretty intense over in the EU with all these new regulations coming into play. The rules for stablecoins under MiCA officially started on June 30, 2024, and the whole MiCA framework will roll out by December 30, 2024. It’s going to be interesting to see how things unfold! Oh, and just so you know, DORA has been up and running since January 17, 2025! Hey there! If you're working with users or organizations in the EU, it’s super important to keep your timeline in sync with these upcoming dates! Want to dive deeper? Check out all the details over at (finance.ec.europa.eu). Happy planning! So, from a banking point of view, we’ve got to have Basel’s cryptoasset disclosure rules and those specific changes for stablecoins all set to go by January 1, 2026. Heads up! Your banking partners are definitely going to want compliant reporting, so it’s a good idea to start preparing now. If you want to dive deeper into this, check out the info at (bis.org).

In the U.S. So, there’s been a big change recently! On January 24, 2025, the SEC made the call to get rid of SAB-121. This is a game changer for banks that want to hold onto digital assets because it clears away a major accounting obstacle. How exciting is that? So, it sounds like we can probably expect more banks to start getting involved in pilots and RFPs soon. Exciting times ahead! If you want to get the complete details, just hop over to this link: (reuters.com).

Wow, these updates have really changed the game! Blockchain programs are now way more affordable to run, super easy to manage, and they’re not just all about research and development like they used to be a year and a half ago. It's exciting to see how far we've come!

The 7‑part Web3 roadmap (what strong consulting engagements deliver)

Aligning Everyone and Putting Together a Strong Business Case. First things first, figure out what big goal you're aiming for. It could be something like reducing cross-border unit costs by 60%, making sure corporate actions are settled in T+0, or even ramping up loyalty redemptions by five times. Just pick something that really matters to you! You know that saying, “If it ships, it sticks”? Well, it's time to really think about what that means for each use case. Take a moment to break down the expected profit and loss impacts over the next year. Don’t forget to highlight the controllable factors, like fees, failure and reversal rates, and those pesky chargebacks. Also, keep in mind the compliance challenges that you’re going to face, such as the location of the stablecoin issuer or the details of the custody model. It might seem like a lot, but it’s all part of making sure everything runs smoothly.

2) Regulatory Runway and Controls Design

Get a Grip on Your Jurisdictional Exposure: Make sure you’re staying updated on what’s happening in the EU with MiCA and DORA, as well as keeping an eye on things in the U.S. Make sure you keep in mind the SEC and other regulatory bodies, along with any special licensing rules that might apply to VASPs in various countries.
Touch Base with Legal: Before you jump in, it’s a good idea to sync up with the legal team to agree on those “compliance gates.” You want to make sure everyone’s on the same page! So, basically, this involves a bunch of tasks like assessing risks, figuring out how long to keep data, picking the right chain analytics vendors, making sure we’re on top of the Travel Rule, and being transparent about bank counterparties based on those Basel crypto templates. It’s all about staying compliant and keeping things running smoothly! Take a look at this: (bis.org). It's worth checking out!

3) Architecture Selection (Narrow to 2 Options)

Decision Dimensions: So, we’re diving into a few important things here. We’re talking about stuff like how stable the transaction costs are, whether everything wraps up smoothly, how well different systems can work together (that’s composability), and what the costs are for data availability (DA). Plus, we can't forget about user identity and experience (UX), how mature our operations are, and the risks that come with our vendors. Hey team, let’s whip up a one-page Architecture Decision Record (ADR) for each option we’re considering: OP Stack, Arbitrum Orbit, app-specific L3, and the permissioned setups like Fabric or Besu. Sound good?

Wallet and Identity Plan.

So, let's talk about the Wallet and Identity Plan! This is all about keeping your digital life organized and secure. It’s where you can manage your online identity, store important documents, and handle your transactions effortlessly. Think of it as your personal shield in the online world, making sure everything stays safe and sound. You'll want to make sure you understand how it works so you can get the most out of it! Choose the wallet models that work best for you. Whether you prefer custodial wallets, MPC/TSS setups, or smart accounts, just go with what feels right for your needs! Don't forget to check out the features coming from ERC‑4337 and EIP‑7702! There's some cool stuff in there, like sponsored transactions, policy engines, and recovery options. They're definitely worth keeping on your radar! For more info, you can dive into the details here. Enjoy!

5) Security Program Fit-Out

Make sure to check out the OWASP Smart Contract Security Verification Standard (SCSVS) and take a look at the OWASP Smart Contract Top 10 as well! It's a great way to stay informed and keep your smart contracts secure. Whenever it feels right, go ahead and opt for EthTrust controls. Let’s move away from using the old SWC registry as our main reference. (owasp.org).

Run a Pilot with Clear Exit Criteria. You'll only move into production once you've hit the KPIs we agreed on, like keeping costs down, nailing the success rate, minimizing latency, and ensuring there are no major regulatory issues at all.

7) Productionization and Scale

It's all about keeping an eye on things around here! We're diving into on-chain metrics and fraud patterns to make sure everything's running smoothly. Plus, we've got some good incident runbooks ready to go just in case! Hey, just a quick reminder to keep change management in mind and make sure business continuity stays on track. This is super important, especially when we run into bumps in the road, like an L2 outage or a bridge halt.

Architecture choices that pencil out in 2026

1) Ethereum L2s (OP Stack Superchain, Arbitrum Orbit)

OP Stack Superchain: Great news! The governance-approved, permissionless fault proofs are now live on OP Mainnet! This means you can benefit from trust-minimized withdrawals, plus there's a clear route toward Stage-2 decentralization across all OP Stack chains. Exciting times ahead! It's just what you need if you're after a smooth Ethereum experience and that cool "multi-chain" feel. Check it out here.
Arbitrum Orbit: Looking to kick off your own app-specific L2 or L3? Arbitrum Orbit has got you covered! You can tweak things like gas tokens (imagine using USDC) and take advantage of AnyTrust mode, which means you’ll enjoy super low fees. It’s a game-changer! On top of that, production deployments can really benefit from those dependable RaaS options. If you're ready to get into the nitty-gritty, check out the details here. It's all laid out for you!

Why This Matters

Alright, so here’s what’s going on: since Dencun happened, those rollups that share "blob" data are experiencing a noticeable decrease in data availability (DA) costs. Pretty interesting stuff! So, what does this mean for folks like us who use these services every day? Basically, we could be looking at fees that dip down to less than a cent for tons of interactions! How awesome is that? This is really promising because it could improve the overall cost-effectiveness for everyday transactions. If you're curious and want to explore more, you can read the full post right here. Trust me, it's worth a look!

Practical Notes

Governance and risk: If you're looking to prove that you're on top of decentralization, definitely take a look at L2BEAT’s Stage framework. It's a great resource that can really help you out! To hit Stage-1, you’ll need to make sure those challenge windows stick around for a minimum of 7 days for Optimistic rollups. If you're curious and want to dive deeper into it, just check it out here.
Vendor strategy: You might want to consider sticking with either the OP Stack or Orbit. It really seems like a smart move! This way, you won't have to worry about making custom operations for every single chain. Both options have pretty reliable multi-chain roadmaps that you can count on.

2) DA layer decisions (Ethereum blobs vs EigenDA vs Celestia)

Ethereum blobs (EIP‑4844): If you're on the hunt for a reliable base for settlement-focused rollups, this is definitely the way to go.
EigenDA: So, this is a cool part of the EigenLayer AVS, and it actually rolled out right when EigenLayer's mainnet went live in 2024. Pretty exciting stuff! It keeps everything safe by connecting with Ethereum’s security using this cool method called restaking. If you're into Ethereum and care about keeping its economic security on point, then this could be right up your alley! (coindesk.com).
Celestia: Imagine this as a flexible way to handle data availability, and the best part? The cost per megabyte is super low! They’re really diving into discussions about how to adjust their pricing to keep it appealing. If you're diving into high-throughput appchains that don’t necessarily rely on Ethereum for settling transactions, then Celestia could be a fantastic option for you. (forum.celestia.org).

Tip: You might want to think about including DA as a line item in your contract, along with a daily forecast in MB/day. It could really help keep things organized! It's definitely a smart move to throw in a renegotiation clause that’s linked to DA pricing proposals or any adjustments at the EIP level.

3) Permissioned stacks (when you need explicit parties, SLAs, and non‑public data)

Hyperledger Fabric: So, the newest version out now is v3! In October 2023, we launched SmartBFT ordering, which brings Byzantine fault-tolerant consensus to enterprise networks. Hey there! If you’re still on version 2, just a heads up! No need to stress! It's still the Long-Term Support (LTS) version, so you’ll keep getting those regular updates and patches. If you're looking for options like modular channels, private data collections, and deterministic chaincode, Fabric is the way to go! Take a look at this: (github.com).
Hyperledger Besu (think of it as enterprise Ethereum): It’s pretty much in sync with the mainnet EVM, so you’re getting a solid performance there. So, looking ahead to 2025, Besu has some exciting plans! They’re really gearing up for Pectra and will be rolling out plugin-based permissioning. At the same time, they’ll be gradually phasing out some of those older privacy and on-chain permissioning features. It's all about keeping things fresh and efficient! They're making a move towards managing privacy using external systems and some cool, modern plugins for handling permissions. More details here: (lf-decentralized-trust.github.io).

Selection Heuristic

If you're looking to get your asset to play nicely with DeFi or liquidity, and you're totally fine with letting people verify it publicly, then I'd say go for a rollup like OP or Orbit that settles on Ethereum. If you're working with familiar partners who are regulated and really focus on keeping data to a minimum, you might want to check out Fabric or a permissioned Besu network. They could be a great fit!

Wallet UX and payments: build what users will actually complete

Smart accounts: So, ERC-4337 is now rolling out on big Layer 2 networks, and it's pretty exciting! It’s packed with neat features like sponsored gas fees, which can make transactions a lot easier. Plus, there are some handy policy-based approvals and recovery options to keep your assets secure. Also, EIP‑7702 gives externally owned accounts (EOAs) the ability to function a bit like contracts. This means you can actually set up some cool product policies directly at the account level--think session keys, spending limits, and role-based approvals. It’s a pretty neat way to manage things! (alchemy.com).
Stablecoins hitting the streets: Back in May 2024, PayPal launched PYUSD on the Solana network. They definitely made a smart choice by choosing Solana for its super quick transaction speeds and minimal fees--it's a game-changer for everyday payments! Fast forward to 2025, and that's when things really took off! Thanks to a partnership with Coinbase, using PYUSD became a whole lot easier. (pymnts.com).
Interop naming: The Mastercard Crypto Credential pilots are a great example of how using aliases can really help reduce those annoying addressing errors that pop up across various exchanges and corridors. It's been interesting to see how this approach makes things smoother! Make sure to set up your send-flow with easy-to-read handles right from the start! It’s super important for clarity. You can check out the details here.

Compliance guardrails to bake in from day 1

EU MiCA/DORA: If you're involved in issuing or backing e-money tokens or asset-referenced tokens in the EU, now’s the moment to get everything sorted out. Just a quick reminder to sync up your disclosures, reserve attestations, and ICT resilience controls with the timelines set by MiCA and DORA. It’s all part of gearing up for your 2025-2026 strategy. Keep it in mind! If you're curious and want to dive deeper into it, you can check it out here.
Basel Cryptoasset Standard: Just a quick heads-up! Starting January 1, 2026, banks will need to start sharing details about their crypto holdings. Get ready for some standardized counterparty requests coming your way! This will include templates and liquidity stress tests specifically for using stablecoins. It's a smart move to get your vendor and SLA packs ready, keeping these upcoming disclosures in mind. Hey, if you're looking for more info, you can find all the details right here.
**U.S. Banking Posture: Since SAB-121 got rolled back on January 24, 2025, there's been a noticeable shift. More banks are now seizing the chance to explore custody and settlement pilots. It's an exciting time as they get to dive into these new opportunities! Make sure to tweak your RFP shortlist as needed! If you want to dive deeper into this topic, check it out here. It’s worth a read!

Security, audit, and resilience: what we mandate on every engagement

Hey there! Just a heads up--when you're putting together your Statements of Work (SOWs) and acceptance criteria, don’t forget to include the OWASP SCSVS and the 2025 Smart Contract Top 10. These should definitely be on your must-have list! These resources really do a much better job of tackling the latest exploit classes compared to the old SWC registry. Take a look at this link: owasp.org. You might find it interesting! When it comes to EVM programs, keeping your upgrade hygiene in good shape is absolutely crucial. So, basically, this involves using UUPS/1967 proxies, managing who can access upgrade paths, making sure we check the storage layouts, and rolling out canary deployments. Honestly, it’s really important not to send out any upgradeable contracts without getting them audited first. If you're looking for more info, check this out: docs.openzeppelin.com.

Create incident runbooks for issues like L2 pauses, bridge failures, DA congestion, and any sequencer hiccups we might run into. Before you dive in, it’s super helpful to run through your exit strategy for L1 and make sure you’re ready for those withdrawal challenge windows. Ideally, you should give yourself at least a week on the more optimistic systems. This little practice can really make a difference once you’re live! For more details, check it out here: (l2beat.com). It's worth a look!

KPIs that separate pilots from production

Cost and Performance
Take a look at the average fee for each successful transaction, sorted by category. Hey, why don't you check out the data access spending for each megabyte? It’d be great to compare the costs for blobs, EigenDA, and Celestia. Hey! So, we’ve got those P50 and P95 times all set for when finality happens and when you can actually start using funds on Layer 1.
Reliability and Risk
Sure thing! Let’s dive into the on-chain failure rate and chat about how frequently refunds actually occur.
We’ll also check out how many withdrawals go through smoothly and how many end up getting pushed back. Oh, and let's not overlook the wallet completion rate! It's really important to keep an eye on how many first transfers and recovery attempts actually go through successfully.
Compliance and Controls
Alright, here’s the lowdown on our open critical audit findings--our aim is to get that number down to zero! We're keeping a close eye on how well we're sticking to our service level agreements (SLAs) for custody, KYC, chain analytics, and node providers.
Business Outcomes
So, we're looking at unit costs and comparing them to the baseline, which includes things like card rails, SWIFT, and the old-school ledgers.
We're also keeping an eye on how well activation and retention are doing when it comes to loyalty and payment processes.

Every quarter, make sure to evaluate your progress and connect funding rounds to whether or not you hit those key performance indicators. This way, you can avoid getting stuck in that endless “perpetual pilot” stage.

Two concrete patterns with current‑gen components

1) Cross-border Stablecoin Settlement (for Consumers or SMBs)

Front-end: Picture a smart wallet that lets you use EIP-7702-style temporary delegation for those batched actions. It’s like having a personal assistant that gets your tasks done while you kick back! We should probably work on setting up some policy modules to help us monitor daily limits and manage allowlists. Take a look at this: (eip.info). You might find it interesting!
Rail: We're thinking about going with Solana, but we might also consider an OP Stack rollup that has sponsored gas. If you're looking for something that gives you that card-like experience, you might want to think about using Crypto Credential-style handles. They can really help create a similar vibe! If you're looking for more info, check out this link: pymnts.com. It's got all the details you need!
KPIs: Make sure to monitor the total cost for each $100 transferred, especially when stacking it up against card and ACH fees. Also, keep an eye on the dispute rate and how long it takes to wrap things up, particularly focusing on the 95th percentile (P95) for completion time.

2) Institutional RWA Tokenization (Bonds/Commercial Paper)

Issuance: So, we can go with a permissioned setup, like using Fabric with SmartBFT for our orderers. Another option is Besu, which comes with QBFT and some handy permissioning plugins. And hey, we can totally handle cash transactions either through on-chain fiat or by linking up with traditional banking systems. It's pretty flexible! Hey, take a look at this on GitHub for all the juicy details!
Distribution: You can choose to have a mirrored version on a public L2, which is pretty cool! By doing this, we create a more open and discoverable environment, all while keeping things organized with less data and a few time delays before sharing certain details.
Proof Points: Just check out Siemens! They've smartly rolled out digital bonds using both public and private channels. Their experiences really highlight how we can speed up settlements and get direct payments to investors. This is a great analogy for executives. If you’re curious to dive deeper into this topic, check it out here. It's definitely worth a look!

Budgeting and TCO you can defend

One-time
Take a look at the architecture and security reviews, as well as the compliance gap analysis.
Have those smart contracts created and make sure to get them independently audited by two different firms. Alright, so here’s the plan: first, we’re going to focus on creating a smooth and enjoyable wallet experience for users. Next, we’ll get our policy engine up and running. After that, we’ll bring in some essential services, like KYC (that’s “Know Your Customer” for clarity), analytics to keep tabs on things, and custody solutions to ensure everything is safe and sound. Sounds like a solid strategy, right?
Recurring (annualized)
Make sure to keep an eye on the DA and L2 fees. It’s a good idea to forecast things in megabytes per month and pay attention to the transaction mix too. So, you'll be taking care of managing node and RPC providers, keeping an eye on observability, handling custody, and diving into chain analytics. Hey, have you thought about setting up a bug bounty program? It could really help you spot vulnerabilities. Plus, regular audits can keep everything in check, and throwing in some tabletop exercises would be a smart way to prepare for any incidents. Just a few ideas to strengthen your security game!
Keep up with compliance reporting, making sure to handle Basel templates, MiCA disclosures, and SOC2/ISO submissions.

Could you run some sensitivity scenarios for the data availability price per MB and the Layer 2 base fees? Thanks! Just a heads up: it’s important to make sure the contract clauses can be tweaked whenever there are changes in the protocol parameters or if new proofs come along--like the roadmap for the OP Stack multi-proof. Flexibility is key! If you're interested, take a look at more details over at optimism.io. There's some cool stuff to explore!

90‑day execution plan (what we deliver)

Weeks 1-3: Let’s start by figuring out which use cases we need to focus on and check out the relevant regulations. We’ll also create a shortlist for ADRs and get the ball rolling on our initial KPI/OKR pack.
Weeks 4-6: During this period, we'll focus on designing some prototype wallet flows that incorporate sponsored gas. We'll also establish the policy rules to guide us along the way. Plus, it’ll be important to sketch out a compliance controls matrix to keep everything in check. On top of that, we’ll be diving into developing our DA and chain cost models. Exciting stuff ahead! Weeks 7-10: Get started on building the pilot! During this time, you'll want to set up an audit schedule and kick off some shadow monitoring. Don’t forget to run a red-team test to see how things hold up. Also, make sure you’re ready with runbooks for Level 2 incidents and any bridge issues that might pop up.
Weeks 11-13: Get ready to host an executive demo! It's time to take a look at the KPIs, and then we’ll have to make the big call on whether we’re moving forward with production or not, based on our funding milestones. Let’s make sure we’re all on the same page!

Emerging practices to watch in 2026

So, with the updates in 4337 and 7702, wallet policy engines are now running at the account level. They’re designed to make sure spending, context, and session key rules are applied consistently across various chains. If you're interested, you can take a look at it right here: (eip.info).

It looks like there's a shift happening towards more standardized multi-chain governance. We're seeing this with initiatives like the OP Superchain charters and something called the "Law of Chains."
"This really helps to make those boring risk and compliance reviews for each and every chain a lot easier." If you’re looking for more details, check out their website at optimism.io. It’s got a ton of useful info! The data availability market is really changing! We’re seeing some pretty straightforward per-MB pricing options pop up on Celestia, along with some interesting restaked-security choices being offered on EigenDA. This gives us a chance to talk about different usage levels and figure out alternatives if we need to. If you want to explore this topic further, check it out here: forum.celestia.org. It's a great place to dig in!

Final checklist for your board packet

We’ve laid out some solid P&L and KPI goals for the upcoming year. Hey there! We’ve got a signed ADR that looks at two different architecture options side by side. Alright, let’s jump into how the wallet and identity user experience works, along with our recovery policy. We're really focused on keeping things secure, so we're jumping on board with standards like OWASP SCSVS and the Top 10. Plus, we've got our audit calendar in place to help us stay on track. You can check it out here: owasp.org. We've put together our regulatory game plan, keeping in mind the timelines for MiCA, DORA, and Basel, along with what’s happening right now in the U.S. banking stance (finance.ec.europa.eu). Oh, and let’s not overlook our incident runbooks, vendor SLAs, and the change-management plan! They’re super important too!

Whenever you're ready to move from just testing things out in the “pilot theater” to actually seeing some real, measurable benefits, 7Block Labs is here for you. We're here to help you get your discovery sprint rolling, set up your pilot project, and guide you through the production process.
