Every time you trade on a new site you sign an approval. Old approvals stay open forever, and that is how most drainers empty wallets. Paste your BNB Chain address and see them all. No connection, nothing to sign.
That swap site from last year can still move your tokens today if you gave it unlimited access.
Most wallet drains don't steal your seed phrase. They use an approval you signed on a fake or hacked site.
Closing an approval is one small transaction. A few cents of gas against everything in that token.
An open approval waits. If you buy that token again, the contract can take it.
Wallet Check only reads public on-chain data. It never asks you to connect or sign anything. Revoke.cash is an independent site, not run by BNSave.
BNSave builds free tools for BNB Chain traders, like Fire Check for tokens and Wallet Check for your wallet. The $BNSAVE token keeps them running: every PancakeSwap trade burns supply and funds charity. Learn more.
