Allowlist
A pre-approved list of addresses eligible to participate in NFT minting before public sale.
What is Allowlist?
An allowlist is a list of pre-approved wallet addresses granted early or exclusive access to an event, such as an NFT mint or a token sale. It is used to manage demand and reward community members.
How does Allowlist work?
- Project creators collect wallet addresses from supporters or contest winners.
- These addresses are added to a smart contract or a Merkle tree.
- During the "allowlist phase," the contract only accepts transactions from these addresses.
- Limits are often set on how many items each allowlisted address can purchase.
- Once the phase ends, the sale typically opens to the general public.
Why does Allowlist matter?
Allowlists prevent "gas wars" where bots and wealthy users outbid everyone else to secure an item. They ensure a fairer distribution and give genuine community members a guaranteed window to participate.
Key features of Allowlist
- Guaranteed access for supporters
- Mitigation of bot activity
- Prevention of gas wars
- Tiered access levels
- Sybil resistance (if combined with social verification)
Examples of Allowlist
- An NFT project giving Discord "OGs" a 24-hour head start to
mint. - A DeFi protocol allowing early beta testers to buy a governance token first.
- A metaverse land sale restricted to existing community holders.
