Repository that shows how to easily implement EIP2981

EIP-2981 Example

Resume

Simple example of implementation of EIP-2981.

In all implementations, royalties are expected to be from 0 to 10000 which allows to define royalties with 2 decimals.

Contract wide royalties

The contract ERC2981ContractWideRoyalties.sol implements ERC2981 with every token having the same royalties recipient and amount.

./contracts/mocks/ERC721WithContractWideRoyalties.sol is an example of ERC721 that would work on a contract-wide royalty base.

Per Token royalties

The contract ERC2981PerTokenRoyalties.sol implements ERC2981 with every token having different royalties

The contracts

• ./contracts/mocks/ERC721WithRoyalties.sol
• ./contracts/mocks/ERC1155WithRoyalties.sol

show how to extend ERC2981 to set royalties at minting time.
