Stablecoin engineering, scoped and productized
7BlockLabs builds tokenization and settlement infrastructure, with SETU as our flagship tokenization OS, and we sell the same senior engineering as productized, fixed-scope services. For stablecoin issuers that means three things we do exceptionally well: getting contracts through a brand-name audit, standing up verifiable proof of reserves, and expanding to new chains without shipping bridge bugs. Clear deliverables, defined scope, no open-ended agency retainer.
Engagements
Scoped pieces in this track
Audit Readiness & Remediation
Pre-audit hardening and remediation so your stablecoin contracts clear a brand-name audit with fewer findings and less back-and-forth.
Typical engagement
Typical engagement: $5k–$20k for a pre-audit hardening and remediation sprint.
Proof of Reserves
Chainlink Proof of Reserve integration, reconciliation pipelines, and public reserve dashboards, built and kept running. Your accountant keeps the attestation; we build the plumbing.
Typical engagement
Typical engagement: a scoped build in the ~$20k–$60k range depending on chain count and data sources, plus a monthly hosting and maintenance retainer to keep feeds, reconciliation, and dashboards live.
Multi-Chain Expansion
Fixed-scope sprints to deploy your stablecoin on a new chain: contracts, bridging via CCTP or LayerZero, tests, and runbooks, one corridor at a time.
Typical engagement
Typical engagement: ~$15k–$50k per chain as a fixed-scope sprint, depending on the chain and bridging model.
Buyer fit
Who this is for
Best fit for seed to Series A issuers and stablecoin-as-a-service teams that have raised enough to move but are staying deliberately lean on blockchain headcount. If you are hiring one or two blockchain engineers instead of twenty, we are the senior bench you point at audit prep, reserves, and chain expansion. We never touch your license, your reserves, or your compliance decisions; those stay in-house.
