What went wrongyear to date, by loss, with the check that catches it
  • Web Application Verification $310.6M
  • Solidity Code Verification $199.8M
  • Wallet Verification $133.9M
  • Ethereum Token Verification $6.1M

Every incident is classified by its reported attack vector, then matched to the service that checks for that vector before execution. A heuristic over DefiLlama's technique field, not a claim that any particular loss would have been prevented.

03Services

Ten verifications, each one call.

04Process

Four steps. Most results in under ten seconds.

Eight of the ten verifications return in under ten seconds. Wallet verification reads 31 chains and web application verification crawls a live site, so those take up to three minutes. Both hand back a job immediately and the page fills in as findings arrive.

09Standards

We wrote the standards, not just the code.

2 final Ethereum standards on eips.ethereum.org, one in Idea. ERC-8126 does not merely resemble this catalogue: it names seven of these services by their own codes, as the checks an agent verification is composed of.
