OpenZeppelin provides a comprehensive suite of tools for building secure, audited smart contracts and applications on Stellar.

Overview

OpenZeppelin Stellar includes:

Tool Purpose Link

Contract Wizard Generate contracts visually wizard.openzeppelin.com/stellar
Relayer Gasless transaction infrastructure Docs
Monitor Real-time contract monitoring Docs
UI Builder Generate React frontends builder.openzeppelin.com

Why OpenZeppelin?

  • Security-First: The library is audited; reports for each release are published in the repo's audits/ directory
  • Battle-Tested: Based on patterns proven across multiple blockchain ecosystems
  • Standards-Compliant: Implements SEP-41 (fungible), SEP-50 (NFT), SEP-56 (vault)
  • Official Partnership: Developed in collaboration with Stellar Development Foundation

Quick Start

1. Generate a Contract

Visit Contract Wizard to generate a fungible token, NFT, stablecoin, vault, or governor contract with your desired features.

2. Use the Contract Library

# Cargo.toml — pin the audited crates.io releases (git deps track unaudited main)
[dependencies]
stellar-tokens = "=0.7.3"
stellar-macros = "=0.7.3"

3. Deploy with Gasless Transactions

Set up OpenZeppelin Relayer to enable gasless transactions for your users.

4. Monitor Your Contracts

Use OpenZeppelin Monitor to track contract events and transactions in real-time.

Contract Categories

  • Fungible Token (SEP-41 compatible) - ERC-20 equivalent
  • Non-Fungible Token (SEP-50 compatible) - ERC-721 equivalent
