What Is a Token Approval?
Token approvals allow a smart contract to spend tokens from your wallet. This is commonly used by decentralized exchanges, NFT marketplaces, lending platforms, bridges, and other Web3 applications.
Approvals are useful, but they can become risky if a contract is malicious, compromised, or left with unlimited spending permission.
What Are Token Approvals Used For?
A token approval gives permission to a contract before an action is executed. For example, swapping tokens, listing an NFT, depositing into DeFi, or interacting with a protocol can require an approval first.
The approval can be limited to a small amount, or it can be unlimited. Unlimited approvals are convenient, but they should be reviewed regularly.
How to Revoke Token Approvals.
Enter your wallet address or domain above to view active approvals. You can then review the spender, token, amount, and date before deciding whether to revoke a permission.
Revoking an approval usually requires a wallet confirmation and a small network gas fee. It does not move your tokens; it only removes the contract's permission to spend them.
