Revoke tools on platforms like Revoke.cash and Etherscan allow users to remove token-spending permissions for a single spender, one token, and one network at a time. These actions do not constitute a wallet-wide reset or guarantee overall security. An empty allowance list does not prove a wallet is safe, as risks can persist through other vectors such as compromised private keys, malicious smart contracts, or cross-chain approvals that remain unaddressed by these tools.
