allowance

Decide whether to grant an ERC-20, NFT or Permit2 allowance before signing it.

Decide whether to grant an ERC-20, NFT or Permit2 allowance before signing it. Send owner, token, spender and amount, or the unsigned approve, setApprovalForAll or Permit2 calldata. Returns allow, warn, block or unknown with the allowance already on chain, the requested scope and the rule behind it, whether this raises or lowers exposure, and whether the spender is a contract, upgradeable or denylisted. Returns unknown rather than guessing. Not a guarantee a spender is honest.
