Sparekey

Who else has a key to your wallet?

Every approval, NFT permission, Permit2 signature and EIP-7702 delegation is a spare key. Paste an address: we check six chains, test what we find, and tell you in plain words which keys to take back.

Read-only. Nothing to sign, and we will never ask for your seed phrase.

The spare keys we look for

We also flag the traps around them: look-alike addresses planted in your history, counterfeit USDT, tokens that say "claim your reward", and tokens moved out by someone other than you.

We test delegations instead of guessing

For every delegated wallet we simulate sending it 1 ETH and read its balance inside the same transaction. A healthy wallet keeps the coin. A sweeper forwards it to the attacker before the block ends. The test runs in a simulation, so nothing is signed or sent.

Explained by Claude, decided by checks

Claude reads the findings and writes what happened, what to do first and what is fine, in English or Bahasa Indonesia. The verdict and every risk level come from deterministic checks, never from the model, and text written on-chain by strangers is treated as data, not instructions.
