OpenZeppelin integrates with TRON to bring battle-tested smart contract security tools to the network
The blockchain security firm's audited contract libraries are now available for TRON developers, backed by familiar tooling and a migration path from Ethereum.
OpenZeppelin, the firm behind the most widely used smart contract libraries in crypto, has officially launched its audited code base for the TRON network. The integration gives TRON developers access to the same security infrastructure that has underpinned much of the Ethereum ecosystem for years.
The launch centers on two new npm packages: @openzeppelin/tron-contracts and @openzeppelin/tron-contracts-upgradeable. These adapt OpenZeppelin’s established libraries for TRON-specific token standards like TRC-20 and TRC-721, the network’s equivalents of Ethereum’s ERC-20 and ERC-721.
What the integration actually includes
The TRON adaptation takes that same code base and reworks it for compatibility with TRON’s TVM, the network’s virtual machine. Because the TVM is primarily compatible with Ethereum’s EVM, the transition is less of a rebuild and more of a careful recalibration. OpenZeppelin’s Engineering Manager, Pepe Blasco, noted that the team focused on implementing network-specific requirements to build trust within the TRON developer community.
The packages support integration with tools that Solidity developers already know: Hardhat, Foundry, and TronBox. OpenZeppelin has also provided resources aimed at easing contract migration for Solidity developers who want to deploy on TRON.
TRON by the numbers
The chain has surpassed $30 trillion in cumulative transaction volume, a figure driven largely by its dominance in stablecoin transfers.

TRON hosts a circulating USDT supply exceeding $94 billion, making it the largest venue for Tether’s flagship stablecoin on any single blockchain.
OpenZeppelin’s libraries have facilitated more than $37 trillion in transferred value across various ecosystems.
The roots of this collaboration trace back to 2025, when the TRON DAO proposed establishing a formal ecosystem stack built on OpenZeppelin’s infrastructure. That proposal has now materialized into production-ready tooling.
The S&P Global backdrop
Just days before the TRON integration went live, S&P Global announced its commitment to acquire OpenZeppelin. For TRON, the acquisition means that the security tools now available to its developers are backed not just by OpenZeppelin’s crypto-native reputation but by the institutional credibility that comes with S&P Global’s involvement.
