Coverage proof
Why Believe Us
90,000,000
every contract on Ethereum
Deduped: 1.5M unique bytecodes · all analyzed.
Scored against 9 vulnerability signals — from Trail of Bits.
Competitors don't publish their coverage. We just did.
Based on tomofumiokubo/not-so-smart-contracts (fork of crytic/not-so-smart-contracts).
9 signals: reentrancy, delegatecall, tx.origin, selfdestruct, ecrecover, send, assembly, create, chain-dependent.

Infrastructure. • Contracts. • Applications
the foundation, the pipes, the taps are all in place.
But no layer yet judges whether
the water coming out is safe.
That's the Trust Layer.
Roadmap
Ninja is Web3 trust.
The accelerator to Web4.
Today
We protect humans.
Tomorrow
AI agents sign more than humans.
