TxFlow said OpenZeppelin completed an independent security audit of its bridge contract, finding zero critical and zero high-severity issues and one medium-severity issue that was resolved during the process. According to BeInCrypto, the review covered Bridge2, the USDC bridge connecting Arbitrum One to TxFlow L1, as TxFlow continues developing its L1, DEX and Builder Code ecosystem. TxFlow said its broader bridge infrastructure supports deposits and withdrawals across Arbitrum One, Ethereum, Base, Polygon PoS and Solana.
