In short
An allowlist is a pre-registered set of addresses permitted to mint early. It spares those buyers the congestion of a public mint and lets the issuer control who gets in. It is also a heavily abused pretext for phishing wallet connections and signatures.
Key points
- A list of addresses allowed to mint early
- Usually verified on chain with a Merkle proof
- Being listed does not always guarantee a mint
- A very common disguise for phishing pages
Definition
A set of addresses permitted to mint before a public sale. The contract verifies membership and only lets qualifying addresses call the mint function.
Storing every address on chain would be prohibitively expensive, so implementations typically use a Merkle tree. The contract holds only the root, and each minter submits a proof that their address belongs. Because the check runs in the contract, the team cannot quietly wave someone through.
Spots are often distributed for community activity or for holding another collection. But some sales issue more spots than there are items and settle them first-come, first-served, so being listed may still leave you without a mint. The contract, not the sales page, is where those rules live.
'Whitelist' is used for much the same thing. The wording differs between projects, but the underlying mechanism — specific addresses minting during a specific window — is the same.
Watch out for
- · Some 'registration' pages ask you to sign approvals that let them move your assets
- · Sites that take an upfront fee for a spot sometimes never mint at all
- · Minting early says nothing about whether the item can later be sold
