AI for Web3
Same process, whatever you build
You see working software and written decisions at every step, and the tests come with the code.
- 1
Discover
We learn the product, the users and what must never go wrong, then write it down as a specification.
- 2
Design
Architecture, threat model and a scoped plan with milestones, reviewed with you before code.
- 3
Build
Small, readable components with tests in every pull request and a demo at each milestone.
- 4
Test & review
Invariant fuzzing, static analysis, fork tests and manual review. Findings arrive as tests you can run.
- 5
Launch & support
Deployment scripts, key ceremonies, monitoring and a runbook. We stay on after launch.

Break a vault with a fuzzer, read the counterexample, then apply the fix and watch the properties hold.
