Smart-contract prototypes with full test suites, ready for a third-party audit.
From $2,000.00
Smart contracts are unforgiving a bug isn't a patch, it's lost funds and lost trust, permanently on-chain. Plenty of teams write Solidity, very few test it rigorously enough to survive a real audit and a failed audit late in the game is expensive.
We build smart-contract prototypes the careful way: requirements and contract design, a Solidity implementation and the part most skip a full test suite with unit and fork tests, deployed to testnet, prepared for a third-party audit and connected to a front end.
Solidity, Foundry/Hardhat unit + mainnet-fork tests, invariant/coverage testing, testnet deployment, audit-prep documentation, front-end (wagmi/viem) connection.

A deployed contract cannot be patched like normal software and a bug can mean permanent loss of funds. Thorough testing before deployment reduces that risk.
We write unit tests, mainnet fork tests and, in the Premium package, invariant tests with coverage reports to show what has been tested.
We prepare your contracts and documentation so that a third party auditor can work efficiently. The audit itself is performed by an independent firm.
We deploy to a public testnet first, so you can review behavior before any mainnet release.
Yes. The Growth and Premium packages include a front end connection using wagmi and viem.
Starter is $2000 in 2 to 4 weeks, Growth is $5490 in 4 to 8 weeks and Premium is $15000 in 8 to 12 weeks. Cloud Care at $299 per month covers monitoring and support.
