Royalty

Royalty

Thirdweb's Royalty is a contract extension to be used with any base contract. It exposes functions for setting and reading the recipient of royalty fee and the royalty fee basis points (BPS), and lets the inheriting contract perform conditional logic that uses information about royalty fees, if desired.

The Royalty contract is ERC2981 compliant.
