TxFlow said OpenZeppelin completed an independent security audit of Bridge2, its USDC bridge connecting Arbitrum One to TxFlow L1. The review identified zero critical and zero high-severity findings, while one medium-severity issue was resolved during the audit. The assessment covers infrastructure that supports capital transfers between external networks and TxFlow L1, whose broader bridge system also supports deposits and withdrawals across Ethereum, Base, Polygon PoS and Solana. TxFlow said its documented bridge flow includes validator-approved withdrawals and a built-in safety wait before withdrawals are completed. The company is continuing development of TxFlow L1, TxFlow DEX and Builder Code as it pursues a financial-market-focused network supporting perpetuals, spot markets, prediction markets and other on-chain financial applications. OpenZeppelin said it has completed more than 900 security audits, identified more than 10,000 issues and secured more than $35 trillion in value transferred since 2015.
