Pain — the specific technical headache you already feel

• Your RFP is stalled behind a 400+ question SIG vendor questionnaire and a “SOC 2 Type II or no-go” red line. Meanwhile, the business wants a tokenization pilot by Q2. (sharedassessments.org)
• Engineering is arguing L1 vs L2 vs “modular DA” while finance wants a crisp gas budget. After Ethereum’s Dencun upgrade (EIP‑4844), L2 fees fell as much as 90–99%—but only if you structure data posting correctly. (investopedia.com)
• You need user experiences without seed phrases and with passkeys/SSO, but your security team insists on enterprise-grade controls and audit trails. ERC‑4337 and passkeys exist, yet your wallet roadmap keeps slipping. (ethereum.org)
• Data-sharing is blocked by privacy and vendor lock-in. You can’t expose internal APIs to partners, yet you must prove facts (balances, certifications, ESG data) to external systems. zkTLS/zkVMs can attest to API results without revealing secrets—but they’re nontrivial to implement. (fosdem.org)
• Regulatory clocks are ticking: NYDFS Part 500 final requirements hit Nov 1, 2025 for financial services, and the EU’s Ecodesign/Digital Product Passport regime begins phasing in from 2026. Your pilots must align to these dates. (dfs.ny.gov)

Agitation — the risk if you wait

• Missed deadlines: Failing to meet NYDFS Part 500’s staged requirements (MFA expansion, asset inventory, logging, third‑party risk) risks supervisory findings and remediation costs just as you seek budget for innovation. (hoganlovells.com)
• Compliance debt: DPP rules under the ESPR entered into force July 18, 2024; delegated acts for priority sectors start landing 2026–2028 with ~18‑month compliance windows. If your supply‑chain data model isn’t verifiable and queryable on day one, you’ll pay twice—in rush work and lost specs. (commission.europa.eu)
• Bad architecture = wasted ROI: Choosing the wrong DA strategy can make L2 costs 10–50x higher than necessary; posting patterns and blob economics matter. A recent analysis showed cost-per‑MB varies widely by rollup; Base and OP Mainnet are orders of magnitude cheaper than others when optimized. (conduit.xyz)
• Vendor lock-in: Wallet UX that ignores account abstraction and passkeys will age poorly; ripping and replacing auth in production is painful and costly. Passkeys are already seeing high sign‑in success and speed improvements at large enterprises. (businesswire.com)
• Market is moving: Tokenized funds like BlackRock’s BUIDL have crossed multi‑billion AUM, are accepted as collateral by major venues, and now run across multiple chains—your treasurer and collateral managers will ask for on‑chain hooks. (coindesk.com)

Solution — 7Block Labs’ methodology that bridges Solidity/ZK with procurement and ROI

We run a 90‑day pilot program built for enterprise constraints. It’s engineered to be “procurement‑ready,” “security-first,” and laser‑focused on measurable outcomes.

1. Value mapping + KPI charter (Week 0–1)

• We translate the business case into chain‑level KPIs: settlement cycle time (T+0/T+1), on‑chain cash yield capture, counterparty risk reduction, and unit economics per transaction/MB posted.
• Deliverables: KPI tree, cost model for L1/L2/DA stack, risk register mapped to SOC 2, NIST CSF 2.0, and applicable regulations. (aicpa-cima.com)

1. Architecture track: right chain, right DA, right wallet (Week 1–3)

• Settlement and DA selection:
  • Default for financial workflows: Ethereum L2 with blob transactions (EIP‑4844) to cut data posting costs; we validate with a DA model that compares Ethereum blobs vs Celestia vs EigenDA based on your data shape and posting cadence.
  • We use real price/per‑MB references and expected blob usage to forecast OPEX; Conduit’s comparative analysis is our baseline, then we tune for your batch sizes. (investopedia.com)
• Identity and UX:
  • ERC‑4337 smart accounts with passkeys (FIDO) for passwordless SSO, integrated paymasters for gas sponsorship, and policy‑based controls for recovery. Ethereum.org tracks large‑scale adoption (tens of millions of smart accounts) that we leverage for ecosystem tooling. (ethereum.org)
• Privacy and attestations:
  • zkTLS to produce verifiable proofs of API facts (e.g., “supplier is ISO‑certified,” “balance >= threshold”) without revealing PII; feasible with TLSNotary/MPC‑TLS stacks now getting mainstream conference coverage. For complex attestations, we offload proofs to a zkVM (e.g., RISC Zero Bonsai) with enterprise SLAs. (fosdem.org)

Relevant services:

• custom blockchain development services → blockchain development services
• DA/rollup and system integration → blockchain integration
• token and asset rails → asset tokenization, token development services

1. Secure-by-design smart contracts (Week 2–7)

• Upgradability patterns you can defend in audit: OpenZeppelin UUPS/transparent proxies with documented upgrade authority; we align governance to change‑management expectations of auditors. (docs.openzeppelin.com)
• Toolchain:
  • Solidity ≥0.8.31 for latest security warnings and EOF readiness; require(bool, Error) support enables clean, gas‑efficient error handling. (soliditylang.org)
  • Foundry for tests, fuzzing, coverage; “gas snapshots” checked into CI to keep a hard budget on gas. Slither + Echidna integrated in CI for static/dynamic analysis. (getfoundry.sh)
• ZK integration patterns:
  • zkVM offload (RISC Zero) with receipt verification on‑chain for high‑assurance compute; use cases include compliant pricing functions, configurable KYC checks, or ESG attestations. (risczero.com)

Relevant solutions:

• audit‑ready code → security audit services
• production‑grade dApps → dApp development
• smart contracts → smart contract development

1. Compliance + procurement pack (parallel, Weeks 1–8)

• SOC 2 mapping: We prepare control evidence aligned to the AICPA Trust Services Criteria and description criteria, so your auditor’s scoping discussion starts at “ready.” (aicpa-cima.com)
• NIST CSF 2.0 alignment: We emphasize the new Govern function to show cyber governance and supply‑chain risk are integral—not bolted on. (nist.gov)
• ISO/IEC 27001 traceability: We map relevant Annex A controls to the pilot’s SDLC, deployment, and vendor management. (iso.org)
• Third‑party risk: Pre‑filled SIG (Lite/Core) artifacts to accelerate security review. (sharedassessments.org)
• Sector‑specific: For financial services, we explicitly map to NYDFS Part 500 amendments and timelines (extortion payment reporting, MFA, asset inventory, logging, Class A controls). (dfs.ny.gov)

1. Integration and data plumbing (Weeks 4–9)

• ERP/TMS/OMS adapters and webhooks; event‑driven indexing for real‑time reconciliation.
• Data availability decisions backed by measured costs: e.g., blob postings with target size/intervals; fallback to Celestia or EigenDA for bulk DA when cost curves justify it. We present a build‑vs‑buy matrix with per‑MB costs and latency tradeoffs for your operations team. (conduit.xyz)

1. Cutover, SRE, and runbooks (Weeks 8–10)

• Observability: on‑chain event monitors, anomaly alerts, and SLIs for settlement times, paymaster success rate, and gas/MB budgets.
• Pre‑production game day: simulate failovers (sequencer congestion, DA fallback), forced upgrades, and key rotations.

Proof — market traction and the GTM metrics that matter

• Tokenization is real and enterprise‑grade: BlackRock’s BUIDL expanded beyond Ethereum to additional chains and is accepted as off‑exchange collateral by Binance; AUM reached multi‑billion by late 2025. This matters because your treasury can now hold tokenized cash equivalents with programmatic settlement. (prnewswire.com)
• Financial market infrastructure is aligning: DTCC’s Smart NAV pilot with Chainlink CCIP standardized on‑chain NAV delivery with 10+ major participants (BNY Mellon, Franklin Templeton, JPMorgan, State Street, etc.). That’s the reference architecture we integrate when mutual funds enter your workflow. (dtcc.com)
• Enterprise blockchain at scale: J.P. Morgan rebranded Onyx to Kinexys, signaling production trajectories for cross‑border payments, tokenization, and privacy; this validates the operating model for bank‑grade systems you’ll interface with. (jpmorgan.com)
• L2 fees after EIP‑4844: Documented reductions up to ~99% on some rollups; the caveat is that your DA and batching strategy determines whether you see the savings. We build those guardrails into CI using gas snapshots. (investopedia.com)
• Account Abstraction maturity: The ERC‑4337 EntryPoint has supported tens of millions of smart accounts and over a hundred million user operations; this underpins enterprise‑grade wallet UX with passkeys and policy controls. (ethereum.org)
• Cost transparency for DA: Empirical per‑MB posting costs differ widely across rollups; our pilot hard‑codes “cost caps” by chain and falls back automatically to optimize spend. (conduit.xyz)
• Governance and risk baselines: NIST CSF 2.0 explicitly elevates governance and supply chain risk; our program ships with mapped artifacts to satisfy InfoSec early. (nist.gov)

Two practical enterprise examples with precise implementation details

1. On‑chain cash management and collateral rails (Treasury/Prime Brokerage)

• Scope: Move a portion of your operating cash or margin collateral into a tokenized money market fund with programmable settlement (e.g., integrate a BUIDL share‑class where eligible).
• Stack:
  • Settlement on Ethereum L2; rollup posting via blobs (EIP‑4844); batched distribution flows with per‑MB targets.
  • ERC‑4337 smart accounts + passkeys with policy‑controlled withdrawals and daily limits.
  • Reconciliation microservice consuming on‑chain events, writing to your GL subledger, and producing audit evidence.
• Controls: SOC 2 evidence mapped to AICPA TSC; NYDFS Part 500 logging and extortion reporting triggers; role‑segregated ops keys; Slither/Echidna/Foundry in CI. (aicpa-cima.com)
• Business outcomes to measure in 90 days:
  • Reduction in settlement fails (FTD) for eligible flows; automated interest sweep policy; real‑time collateral reuse.
  • Wallet support rate (passkey success >90%) and time‑to‑sign (≤10s) based on FIDO passkey benchmarks. (businesswire.com)
• Where we help: integration with custodians/venues; collateral orchestration; and RWA hooks using our asset tokenization playbook and cross-chain solutions.

1. Digital Product Passport (DPP) for supply chain compliance (Manufacturing/Retail)

• Scope: Prepare for ESPR‑driven DPP rollouts (starting 2026–2030) by building a verifiable, privacy‑preserving product data layer. (commission.europa.eu)
• Stack:
  • Product identifiers (GS1/GTIN) hashed on-chain with pointers to structured data; access controlled by policy.
  • zkTLS attestations proving supplier certifications (e.g., ISO/IEC 27001 or environmental claims) without leaking PII; proofs anchored on chain for auditability. (fosdem.org)
  • DA strategy that minimizes OPEX: meta‑data on chain, bulk docs in modular DA when cost‑effective; per‑MB caps enforced in CI (Conduit reference). (conduit.xyz)
• Controls: NIST CSF 2.0 Govern and Identify functions, SOC 2 mapping, and GDPR posture review given rising EU penalties. (nist.gov)
• Where we help: schema design, partner onboarding, and audit‑ready trails through our blockchain integration and web3 development services.

Technical spec snapshot you can hand to engineering
