Frequently asked questions

What is Lanyard?

When it is mentioned that your allowlist will work across web3, it means that Lanyard securely stores your allowlist, Merkle root, and proofs so that your community can mint your project from various interfaces, including your website, mint.fun, and any other platform that integrates Lanyard.

A Merkle root is a popular method used to handle allowlists for projects on the blockchain.
