Client Testimonials
Trusted by teams who can't afford downtime
Alice Chen
CTO, Meridian Protocol
"Chaincraft delivered our entire lending protocol ahead of schedule. Their formal verification process found edge cases our previous auditors missed. We've had zero security incidents in 14 months of production."
Brian Okafor
Founder, Nova Ventures
"The team's deep understanding of blockchain architecture helped us raise our Series A in 6 weeks instead of 5 months. Investors specifically cited the quality of our deployed contracts as a key de-risking factor."
Carla Reyes
Lead Developer, CoreLedger
"Working with Chaincraft was a game-changer for our project. Their AI-powered code generation delivered a full NFT marketplace in 11 days. The quality was indistinguishable from a manually-written codebase."
FAQ
Answers, not ambiguity
We are production-ready on Ethereum, Solana, Polygon, Arbitrum, Avalanche, and zkSync Era. For enterprise clients we can also stand up a private, permissioned chain using Hyperledger Fabric or Cosmos SDK. Our AI tools support Solidity, Rust, and Vyper.
Security is a 4-layer process: (1) formal verification with Certora and symbolic execution, (2) AI-based vulnerability scanning across 400+ CWE patterns, (3) line-by-line manual review by our senior engineers, and (4) a third-party audit by CertiK or Hacken, which we coordinate and manage for you. Our incident rate since 2019: 0.00%.
We follow a fixed 6-phase delivery framework: Discovery & Planning (2 weeks), Design & Architecture (1 week), Development Sprints (2-8 weeks depending on scope), Rigorous Testing & QA (included), Deployment (mainnet or testnet), and Post-Launch Support (90 days minimum, extendable). Every phase has a defined deliverable and a named technical lead.
For context: a standard ERC-20 token with fee logic ships in 2 weeks. A full lending protocol averages 6-8 weeks. An NFT marketplace with off-chain indexing runs 4-6 weeks. A custom Layer 2 ranges 4-6 months. You'll receive a date-specific roadmap at your initial consultation, not a range.
Yes. Every contract ships with a 90-day warranty covering bug fixes and security patches. After that, 89% of clients renew into a monthly care package: Gold Plan ($1,250/mo — monitoring + hotfix SLA), Platinum Plan ($3,900/mo — everything in Gold, plus new feature development and priority access to our AI tooling).
