Sparekey checks the spare keys on your crypto wallet
A read-only wallet security scanner that checks EVM addresses across six chains for risky approvals, signatures, delegations, and other drain risks.
- For
- EVM wallet holders checking delegated permissions
- Worth noticing
- For delegated wallets, it simulates a 1 ETH transfer inside the same transaction; nothing is signed or sent.
Field notes
The scan accepts an EVM address or ENS name, then checks approvals, Permit2 allowances, delegations, NFT access, address poisoning, bait tokens, and known drainers across six chains. For delegated wallets, it simulates a 1 ETH transfer and checks whether the funds remain or are forwarded within the same transaction. The page says it matches parties against ScamSniffer's open drainer list and OFAC's sanctions list; a Claude-written plan is offered in English or Bahasa Indonesia.
