Web3 approval security scanner

Wallet approval risk scanning with one-click revoke.

Custom

Challenge

Wallets accumulate token approvals for years — some to contracts later flagged as malicious — with no tool to surface the exposure and act on it quickly.

Solution

Built an on-chain approval scanner that cross-references a risk database, ranks findings by value at risk, and offers batched one-click revocation — multi-chain, hardware-wallet friendly.
