ERC-3525 Reference Implementation

This is reference implementation of ERC-3525.

ERC-3525, proposed by Solv Protocol, is a standard for the Semi-Fungible Token (or SFT) approved by the Ethereum community.

It defines a new type of digital asset characterized by the following key features:

  • Unique ID and expressivity of ERC-721 non-fungible tokens. Compatibility with the ERC-721 token standard.
  • It is fractionalizable, combinable, and computable.
  • It can work like an account and nest other digital assets, including ERC-20 fungible tokens and NFTs, with support for token-to-token transfer.
  • Programmable appearance, functionality, lockup, transfer, etc. Metadata is optimized to support dynamic inputs and more complex financial logic.

🧙Not sure how to get started? Check out ERC-3525 Starter Kit: Developer Edition - a step-by-step guide to get you started with the ERC-3525 reference implementation.🚀

Overview

Installation

npm install @solvprotocol/erc-3525@latest

Usage

Once installed, you can use the contracts in the library by importing them:

pragma solidity ^0.8.9;

import "@solvprotocol/erc-3525/ERC3525.sol";

contract MyERC3525 is ERC3525 {

constructor()
    ERC3525("MyERC3525", "MY3525", 18) {
    }
}

To keep your system secure, you should always use the installed code as-is, and neither copy-paste it from online sources nor modify it yourself.

ERC-3525 White Paper

Security

This project is maintained by Solv Protocol with the goal of providing a ERC-3525 Reference Implementation for the SFT ecosystem. We address security through risk management in various areas such as engineering and open source best practices, scoping and API design, multi-layered review processes, and incident response preparedness.

Past audits can be found in audits/.

Smart contracts are a nascent technology and carry a high level of technical risk and uncertainty. Although the ERC-3525 Reference Implementation has been audited, using it is not a substitute for a security audit.

ERC-3525 Reference Implementation Contracts is made available under the MIT License, which disclaims all warranties in relation to the project and which limits the liability of those that contribute and maintain the project, including Solv Protocol. As set out further in the Terms, you acknowledge that you are solely responsible for any use of ERC-3525 Reference Implementation Contracts and you assume all risks associated with any such use.
