How to Implement ERC5169

Implement manually

Implementing ERC-5169 can be conveniently achieved by inserting several lines of code.

1. Install stl-contracts package:

npm

npm i stl-contracts

pnpm

pnpm add stl-contracts

yarn

yarn add stl-contracts

bun

bun add stl-contracts

2. Add following code to your contract

import "stl-contracts/ERC/ERC5169.sol";

contract ERC721Mint is Ownable, ERC5169, AccessControl, ERC721Enumerable {

  function supportsInterface(bytes4 interfaceId) public view override(ERC5169, ERC721Enumerable) returns (bool) {
    return ERC721Enumerable.supportsInterface(interfaceId) || ERC5169.supportsInterface(interfaceId);
  }

  // limit set contracts to admin only
  function _authorizeSetScripts(string[] memory) internal view override(ERC5169) onlyOwner {}
}

3. In case if you don’t implement Ownable interface then replace onlyOwner with your modifier to limit use of _authorizeSetScripts to admin or other user/group

4. When contract deployed run the following script to set the scriptURI

const [owner] = await ethers.getSigners();

const ERC721Mint = await ethers.getContractFactory("ERC721Mint");
const nft = await ERC721Mint.attach(contractAddress);

let tx = await nft
  .connect(owner)
  .setScriptURI(["https://your.hosting.com/messaging_mumbai.tsml"]);
await tx.wait();

When script added then NFTs (which user own) for this contract will appear under Smart Layer Launchpad
