Approvals & Allowances

Check how much a smart contract can spend from your wallet, approve a new amount, or revoke access completely. Reads and writes use your connected EVM wallet.

Amount to Approve (human units) Approve unlimited (Max)

Use a precise amount for safer approvals. Unlimited is convenient but risky if the contract is compromised.

This uses allowance(owner, spender), approve(spender, amount) and decimals() directly on the ERC-20 contract. Checking allowance is a free read; approving/revoking requires a normal on-chain transaction from your wallet.
