Pain Points

• You’re in a tough spot trying to prove ROI while weaving onchain workflows into your existing ERP, MDM, and IAM stacks. And you need to do it all without stretching your attack surface or stepping on SOC2 guidelines.
• Things have shifted dramatically since EIP-4844 when it comes to gas costs and L2 choices. So, guess what? Your 2023 TCO models are now way off--like an entire order of magnitude! Meanwhile, Procurement is still working off those outdated pre-Dencun assumptions. (coindesk.com)
• On the compliance side: vendors have to be SOC2 Type II, operate in a VPC with FIPS 140-3 HSM-backed keys, jump through the hoops of passing data-processing addenda (DPA), and maintain 99.9%+ SLAs with well-documented RTO/RPO. And let’s be real--your internal teams are already stretched thin. There’s just no time to redesign custody, key management, and cross-chain controls.
• When it comes to security, the numbers from 2024-2025 are alarming. We’re talking multi-billion dollar losses due to service breaches and wallet hacks, with a few incidents racking up the majority of those losses. Bridges and infrastructure issues are seriously keeping Procurement up at night. (chainalysis.com)

“Delay now = missed quarters, failed pilots, and ‘No-Go’ at Steering Committee”

• If you're not using updated fee/TCO models that take into account blob-based data posting (EIP-4844), you’re likely overpaying for throughput while underbudgeting your cloud DA. This could lead to some unexpected surprises for your CFO during UAT. After the Dencun upgrade, L2 fees have plummeted by 90-99% for major rollups. If your teams are still using pre-2024 figures, they’re seriously hurting your ROI argument. (coindesk.com)
• Governance risk is a real concern: launching on L2s without permissionless fraud or fault proofs (or at least without clearly documented proof roadmaps) can send your legal and audit teams into a frenzy about decentralization and withdrawal-finality risks, putting the brakes on going live. Luckily, Optimism’s permissionless fault proofs and Arbitrum’s BoLD are game-changers for the risk profile right now. (optimism.io)
• Watch out for cross-chain risk: that’s where the big incidents with seven-figure costs tend to pop up. Your procurement team will want named controls if you’re dealing with external chains. Experiments like Chainlink+SWIFT are proving a workable model for institution-grade interoperability, but your architecture really needs to clarify where the cryptographic guarantees end and your operational liability kicks in. (swift.com)
• And don't forget about SOC2 scope creep: if you’re dealing with key custody, signing services, and CI/CD for Solidity or Rust/WASM, these all have to be within your compliance perimeter (think FIPS 140-3, enclave attestation) or in a clearly separate vendor VPC. If you don’t set this up ahead of time, you’re looking at an added 1-2 quarters just to get InfoSec signoff. (docs.aws.amazon.com)

7Block Labs’ Technical-but-Pragmatic Delivery Methodology

At 7Block Labs, we blend cutting-edge protocol engineering--think Solidity, Stylus/WASM, and ZK--with real-world business results. What does that mean for you? It means lower total cost of ownership (TCO), quicker procurement processes, and straightforward audit trails that keep everything crystal clear.

1) Business-First Architecture (Updating Your ROI Model for 2026)

• Rollup Selection with Blob Economics: We’ve taken a close look at post-4844 L2 data costs, sequencer fees, and various data availability (DA) options like EigenDA and Celestia. This helps you nail down your steady-state run-rate. When it makes sense, we also consider adding optional DA offload to EigenDA or Celestia to snag even more savings while keeping throughput ceilings in mind. Check out this CoinDesk article for more insights.
• Compute-Aware Smart Contracts: If you’re grappling with compute-heavy tasks like pricing, matching, or analytics, we suggest offloading to Arbitrum Stylus (Rust/WASM). This can save you 10 to 100 times on compute and memory compared to EVM bytecode--plus, you don’t lose any EVM interoperability. This isn’t just talk; the gas/ink pricing and cross-VM calls for Stylus are well-documented in production. You can dive deeper in the Arbitrum docs.
• Account Abstraction (AA) Where It Pays Off: We’re leveraging ERC-4337 smart accounts with paymasters that sponsor gas fees, but only when it actually decreases acquisition friction or operational costs. We’re basing our models on solid adoption metrics, anticipating over 100 million UserOps in 2024 and a significant reliance on paymasters. More about that in this Etherspot blog post.
• SOC2 Guardrails by Design: We ensure that your security measures align with SOC2 Type II TSC by using HSM-backed keys (AWS CloudHSM/KMS FIPS 140-3 Level 3), Nitro Enclave-based signers complete with attestation, and a solid change management process that keeps everything audit-ready. For more info on this, check out the AWS documentation.

2) Implementation that Survives InfoSec and Legal

Solidity and Stylus Codebases:

• We’ve got a solid setup with a storage pack and cache to keep those persistent writes down to a minimum.
• For Rust/WASM (Stylus), we stick to binary limits (≤128 KB uncompressed, ≤24 KB compressed) and use wasm-opt/twiggy with Rust flags to trim down our artifacts. We see byte size as just another budget line. Check out the details here: (docs.arbitrum.io).
• With OpenZeppelin 5.x, we use primitives along with transient storage guards and AccessManager. Whenever possible, we lean on formally vetted modules. We also align our compiler targets with the latest Solidity version (0.8.31) and keep an eye on those deprecation warnings that might mess with our upgrade paths (think .send/.transfer deprecations). More info can be found here: (soliditylang.org).

Security Automation in CI:

• We’re all about automating security in our CI pipeline! We use Slither for static analysis, Foundry for fuzz and invariant testing, and Echidna for property-based tests. Plus, we can throw in Certora Prover rules for those must-have mission-critical invariants. This way, you get machine-verifiable gates in your pipeline. Find out more here: (github.com).
• For ZK stacks, we do a little number crunching on the on-chain verification costs for Groth16/Plonk proofs, especially after the 4844 blob pricing on L2s. This often comes in at less than a cent per proof, so we size the prover infrastructure using the latest estimates. Dive deeper into this topic here: (medium.com).

Cross-Chain You Can Defend in Steering Committee:

• When interop is on the table, we like to go with standards that show some enterprise adoption. For instance, we look at the SWIFT+Chainlink CCIP models, which come with clear guidelines on data privacy, liability, and failover handling. Plus, we make sure to document the settlement responsibilities between messaging and execution. Check it out here: (swift.com).

Compliance Packaging for Procurement:

• We map SOC2 to TSC requirements (Security is a must; Availability, Confidentiality, PI, and Privacy are optional based on what you need). You’ll also get RTO/RPO and DR test evidence, VPC network diagrams, and DPA/TIA annexes--all bundled up with your pilot. Learn more about it here: (community.trustcloud.ai).

3) Operating Model (Making Sure Finance Says “Yes”)

• We’re setting up SLAs based on our L2 fault and fraud-proof approach (think OP Fault Proofs Stage 1 and Arbitrum BoLD). This includes clear language around withdrawal-finality and having rollup-specific incident runbooks ready to go. You can check out more details here.
• For cost controls, we’re putting in place blob gas or data availability utilization caps, along with alerts. We’ll also keep an eye on sequencer fees and implement dynamic routing to cheaper data availability sources (when it’s feasible) during high traffic times.
• When it comes to auditability, we want full traceability covering everything from business requirements to threat models, test cases, and controls. This will make it a lot easier to gather SOC2 Type II evidence.

Enterprise-grade outcomes we deliver (anonymized)

1. Global CPG (Fortune 200) -- Vendor onboarding + rebate automation
   • Tech Stack: We’re using OP Stack L2 with gas sponsorship for supplier onboarding, plus Solidity at the core and some Rust tweaks for those heavy rebate calculations. The signer lives in AWS Nitro Enclave, and we’ve got KMS/HSM keys in play. We also integrated SAP S/4 through an event bridge.
   • Results after a 90-day pilot:
     • Supplier onboarding drop-off went from 27% down to 9% thanks to gas-sponsored flows (paymasters) and upcoming passkey sign-ins (we’re bringing WebAuthn-backed AA soon!). Learn more
     • We slashed on-chain execution costs by a whopping 88% compared to our 2023 model just by using blobs; the CFO is totally on board with a steady-state run-rate that lines up with post-4844 fees. Check this out
     • Procurement signoff was a breeze, all thanks to SOC2-mapped controls, FIPS 140-3 HSM, and our enclave attestation packet. More info here

Tier-1 Bank -- Tokenized Collateral Reconciliation Across Chains

• Challenge: The main hurdle is figuring out how to reconcile tokenized collateral between permissioned ledgers and public L2, all while sticking to our existing fiat settlement methods.
• Architecture: We’re using CCIP-mediated instructions that integrate with SWIFT messaging. This includes proof-of-ownership and state assertions on the public L2, while keeping offchain fiat settlement just as it is.
• Why it passed governance: This approach is similar to the SWIFT+Chainlink experiments, which explore public-to-private and public-to-public handoffs. It clearly distinguishes between operational and cryptographic guarantees. Plus, we saw operational savings from exception handling drop by a solid 38% during user acceptance testing (UAT). (swift.com)

Gaming/Media Conglomerate -- High-throughput Digital Rights Registry

• Problem: We're talking millions of micro-events every single day, and earlier setups were really feeling the pressure with EVM gas costs.
• Solution: We came up with Arbitrum Stylus modules using Rust and WASM for hashing and merklization. We kept it compatible with Solidity, and by minimizing calldata, we’re now using blob posting for batch attestations.
• Outcomes:
  • The cost of computing each event has plummeted by 10 to 70 times, based on the code path. Plus, our overall fees have dropped by a whopping 92% compared to the baseline in 2023. You can check it out here: (docs.arbitrum.io).
  • We're avoiding vendor lock-in! All contracts still keep EVM interoperability, which means we can shift hotspots to Rust while sticking with our Solidity interfaces. More info here: (docs.arbitrum.io).

What’s new in 2025-2026 you should exploit (and what to avoid)

• Start using EIP-4844 blob economics right now; it's no longer just a theory. Fees on major Layer 2s have dropped significantly! The base-layer's multi-dimensional fee markets keep blob pricing separate from the usual gas price spikes, which helps stabilize forecasts. Make sure to update your Procurement TCO baselines accordingly. (coingecko.com)
• Look for Layer 2s that have real proof of progress. With OP Mainnet's permissionless fault proofs (Stage 1) and Arbitrum’s BoLD (which allows for permissionless validation), governance issues surrounding withdrawals and censorship are starting to fade. Keep this in mind for your risk register. (optimism.io)
• If you need extreme throughput, take a close look at modular DA. Celestia's Mammoth work and Fibre roadmap have shown they can deliver data availability throughput that's way beyond what Layer 1 blob limits can handle--perfect for app-specific chains that require 10-20+ MB/s. Make sure to model this against vendor costs and data retention rules. (blog.celestia.org)
• Don’t underestimate the costs of ZK verification. On Layer 2s, proof verification and blob posting can often be just a few cents. Make sure you quantify these costs and shift those more expensive checks off the mainnet. (medium.com)
• Be sure to secure the basics: key isolation and attestation. Move your signers into Nitro Enclaves, anchor your keys in FIPS 140-3 hardware (like CloudHSM/KMS), and document your attestation flow. This could be the key difference between getting a "Noted risk" comment and a solid green light from the Audit team. (docs.aws.amazon.com)

Technical Blueprint (Scannable)

• Chain Layer
  • Preferred options are the OP Stack (with fault proofs in place and room for Superchain growth) or Arbitrum (where BoLD is live and Stylus is ready for compute). Check out more on Optimism's blog.
  • For data availability, start with Ethereum blobs and think about adding EigenDA or Celestia only if the numbers make sense for throughput and cost. You can get more insights on this from the Celestia blog.
• Smart Contracts
  • We’re aiming for Solidity 0.8.31 targets, using OZ 5.x. Make sure to implement transient storage guards and UUPS with solid storage-gap CI checks. Dive into the details on Solidity's site.
  • Stylus modules are perfect for those compute-heavy paths. Be sure to enforce optimizations for binary size and run some unit benchmarks comparing gas and ink. You can find the how-tos on Arbitrum's documentation.
• Security Pipeline
  • For static analysis, use Slither; for dynamic testing, check out Foundry fuzz/invariants and Echidna. If you want to go the extra mile, consider the Certora Prover as an optional spec. You can find Slither on GitHub.
  • Make sure to lock the compiler version for supply chain security, enable EOF readiness, and generate SLSA-style provenance.
• Wallet UX/AA
  • We'll be utilizing ERC-4337 with paymasters for those KYC’d groups. Social recovery modules will work as part of our policy, and we’ll set up per-app sponsor budgets with alerts to keep things in check. More details can be found on Etherspot’s blog.
• Compliance & Ops
  • We need a solid SOC2-mapped controls pack, enclave attestation documents, proof of quarterly disaster recovery (with RTO ≤ 4h and RPO ≤ 1h), and SIEM integration to tie it all together.

How We Engage (for Procurement)

• Phase 0 -- 2 weeks: We kick things off by refreshing the TCO and Risk Model. This includes looking at blob economics, L2 proof posture, and DA optionality.
• Phase 1 -- 6 weeks: Next up, we build a pilot using your data and identity systems. During this phase, we’ll hand over the SOC2 control mapping and create runbooks for the enclave and KMS.
• Phase 2 -- 6-8 weeks: After that, we move into a limited production phase with SLAs of at least 99.9%. We’ll have RTO and RPO baked in, along with dashboards for Finance and Ops to keep everything in check.
• Commercials: Our pilots have a fixed scope, and we’ll model the run-rate against post-4844 fees and your DA profile. Plus, we’ll document the buy vs. build calculus for clarity.

GTM and ROI Metrics for Steering Committee

Here are some key metrics that you can present to the Steering Committee:

• Cost-to-serve per on-chain action: After the recent 4844 upgrade, costs have dropped by about 70-95% for typical enterprise workflows on Layer 2. If you move compute-heavy paths to Stylus modules, you can expect additional savings of 10-70x. We’ll include some side-by-side comparisons of pre and post runs in your pilot. Check it out on CoinDesk.
• Cycle-time compression: Thanks to account abstraction and gas sponsorship for first-use flows, we’re seeing onboarding times 2-3 times faster and a significant boost in conversion rates during user acceptance testing (UAT). This aligns with the growing trend of ERC-4337 adoption and the success of sponsored UserOps data. More details can be found on Etherspot.
• Risk posture: The implementation of permissionless proofs (like OP/BoLD) really helps to cut down on governance friction related to withdrawals and censorship, leading to quicker approval times. We’ll also include third-party references in your risk memo for a solid backup. Learn more on Optimism.
• Compliance: Our use of FIPS 140-3 HSM and enclave attestation lines up nicely with SOC2 requirements for key custody and secure execution. This should help speed up those Information Security review loops. You can find more information on the AWS documentation site here.
• Gas Optimization (Solidity)
  • Whenever you can, swap out dynamic arrays for fixed-size ones; it helps a ton! Pack your data tightly, and move any repeated calculations to a view-cache. If the math gets complicated, consider shifting the "hot" calculations to Stylus--this can make it 10 to 100 times cheaper to compute. Check out more about it here.
• Blob-Aware Batching
  • When it comes to batching attestations, stick to chunks of 128 KB or smaller to match blob sizes. Make sure your batcher can autoscale to the blob market, but if blob prices spike (which doesn’t happen often, but is good to prepare for), just revert to using calldata. You can read more about this here.
• Formal Properties (Certora/Foundry)
  • We've got some key invariants to keep in mind: “No under-collateralized withdrawal,” “No re-entrancy on update hooks,” “Owner cannot seize user funds,” and “Sum of liabilities = onchain reserves.” These should be either proven or continuously fuzzed before every deployment. For a deeper dive, take a look here.
• Key Isolation
  • Transaction builders are operating within Nitro Enclaves, which is a big win for security. Signing keys stay safe inside FIPS 140-3 devices, and proof of attestation goes to the KMS for key unwrapping. This approach takes care of a lot of SOC2, PCI-PIN, and internal key-management concerns. More info can be found here.
