Smart Contract Engineering
Design and implement production-grade EVM smart contracts with clear invariants, tight access control, and test coverage that actually reflects real risks.
Outcome-focused delivery
Secure, gas-optimized Solidity and integrations built for production.
Client details are private by default. Public examples are anonymized.
Who it’s for
- Protocols shipping new modules or upgrading existing contracts
- Teams integrating DEXs, oracles, lending protocols, routers, or aggregators
- Operators who want safe withdrawals, instrumentation, and deploy/rollback notes
What we won’t do
- Token sales, fundraising promotion, or “guaranteed yield” claims
- Copy-paste forks with no testing or review budget
- “Ship today, fix later” timelines for high-value deployments
What you receive
- Solidity codebase + unit/integration tests
- Architecture notes (assumptions, invariants, trust boundaries)
- Deployment + rollback checklist (and migration guidance if needed)
- Event instrumentation notes for monitoring and incident review
How an engagement runs
We keep it structured so production doesn’t turn into improvisational theatre.
- Discovery: Map requirements, constraints, and threat surface
- Design: Propose architecture and explicit invariants
- Implementation: Write contracts with tests and review checkpoints
- Handover: Deploy notes, rollback plan, and operational guidance
Representative examples
- Project 01: EVM Contract System · Access control, safe withdrawals, and instrumentation
- Project 03: Threat Modeling · Integration risk review before launch
FAQ
Do you do audits?
We do security-minded reviews and threat modeling. Formal audit deliverables can be supported, but scope is agreed in writing.
Do you write tests?
Yes. Tests are part of the deliverable, especially around permissioning, invariants, and critical flows.
Do you handle deployments?
We can support deployments, but deployment ownership and custody boundaries are explicitly scoped.
Send a short scope
Tell us what you’re building, your constraints (chain/protocol/timeline), and what “done” means. We’ll respond with a written scope or a clear “not a fit.”
