Immutable Contracts

Immutable Contracts is a library of smart contracts targeted at developers who wish to quickly build and deploy their smart contracts on the Immutable X and Immutable zkEVM, a general-purpose permissionless L2 zero-knowledge rollup. The library allows developers to build on contracts curated by Immutable, including (but not limited to):

• Token presets, e.g. ERC721

  • ImmutableERC721
  • ImmutableERC721MintByID
  • ImmutableERC1155
  • ImmutableERC20MinterBurnerPermit
  • ImmutableERC20FixedSupplyNoBurn

• Bridging contracts

• Marketplace and AMM contracts

• Smart Contract Wallets

• Random Number Generation

These contracts are feature-rich and are the recommended standard on Immutable zkEVM intended for all users and partners within the ecosystem.

Setup

Installation

$ yarn add @imtbl/contracts

Usage

Contracts

Once the contracts package is installed, use the contracts from the library by importing them:

pragma solidity >=0.8.19 <0.8.29;

import "@imtbl/contracts/contracts/token/erc721/preset/ImmutableERC721.sol";

contract MyERC721 is ImmutableERC721 {
    constructor(
        address owner,
        string memory name,
        string memory symbol,
        string memory baseURI,
        string memory contractURI,
        address operatorAllowlist,
        address royaltyReceiver,
        uint96 feeNumerator
    ) ImmutableERC721(
        owner,
        name,
        symbol,
        baseURI,
        contractURI,
        operatorAllowlist,
        royaltyReceiver,
        feeNumerator
    )
    {}
}
