SFT (ERC-1155)

Pallet Precompile

Use this precompile to interact with the sft runtime pallet to create an ERC-1155 collection.

Contract Address

0x00000000000000000000000000000000000006c3

Solidity Interfaces

interface TRNSFT {
  event InitializeSftCollection(address indexed collectionOwner, address indexed precompileAddress);

  function initializeCollection(address owner, bytes calldata name, bytes calldata metadataPath, address[] calldata royaltyAddresses, uint32[] calldata royaltyEntitlements) external returns (address, uint32);
}

Token Precompile

Contract Address

The ERC-1155 contract address for The Root Network native semi-fungible tokens uses the following format:

0xBBBBBBBB[4-byte-collection-id]000000000000000000000000

To make things easier, the @therootnetwork/evm provides a handy function to convert token asset ID to its equivalent contract address.

import { collectionIdToERC1155Address } from "@therootnetwork/evm";

const COLLECTION_ID = 1;
const COLLECTION_CONTRACT_ADDRESS = collectionIdToERC1155Address(COLLECTION_ID);
