setApprovalForAll is a function in the ERC-721 and ERC-1155 standards. When called with the approval flag set to true, it designates an operator address that, in the spec’s words, “can manage all NFTs of the owner” for that contract. Unlike a single-token approve, this is a blanket authorisation covering every token you currently hold in that collection and any you acquire later.

Why it matters

Marketplaces and other tools legitimately use setApprovalForAll so they can list or transfer your NFTs without a fresh approval each time. But the same breadth makes it a favourite target for scams. A fraudulent site may present what looks like a routine action while actually requesting operator rights over an entire collection, after which the operator can move every item in it.

Common misunderstanding

Users often read the request as approving a single NFT or a single sale. It is not; it approves the whole collection to one operator until revoked. Another mistake is assuming a granted operator becomes harmless after the intended action. The approval persists on-chain, so a malicious or later-compromised operator retains the ability to transfer your tokens. As with ERC-20 approvals, reviewing and revoking operator approvals through a block explorer or approvals tool is how you close that exposure. Because the grant covers future tokens too, revoking it once you have finished using a marketplace is sound routine hygiene, not an overreaction. Treating broad approvals as temporary rather than permanent, and revoking them when done, keeps your exposure low.

Frequently asked questions

Does setApprovalForAll cover only one NFT?
No. It grants an operator control over all your tokens in that collection, present and future, until you revoke the approval.
