TxFlow has completed an independent security audit by OpenZeppelin, one of the world's most established blockchain security firms, for its bridge contract infrastructure. According to TxFlow's announcement, OpenZeppelin's review covered the bridge contract, a critical component supporting capital movement between external networks and TxFlow L1. The audit identified zero critical and zero high-severity findings, with only one medium-severity finding that was resolved during the audit process. This security review forms part of TxFlow's broader approach to incorporating external security expertise as its financial infrastructure continues to develop.
OpenZeppelin brings significant security credentials to the partnership, having completed more than 900 security audits and identified more than 10,000 issues, including 700+ critical and high-severity vulnerabilities across blockchain protocols and financial infrastructure. As reported by TxFlow, OpenZeppelin's security work spans major crypto organizations including Coinbase, the Ethereum Foundation, Uniswap, Aave, Arbitrum, ZKsync, Optimism, and Compound, as well as established financial institutions like DTCC, Fidelity Digital Assets, WisdomTree, ANZ, and CACEIS. The audit report provides technical scope, findings, and assessment from OpenZeppelin and is available for community review directly. Since 2015, OpenZeppelin has secured more than $35 trillion in value transferred and delivered 900+ security engagements, with its open-source smart contract libraries serving as industry standards across leading stablecoins and blockchain applications.
TxFlow's bridge infrastructure supports deposits and withdrawals across Arbitrum One, Ethereum, Base, Polygon PoS, and Solana. According to the announcement, the documented bridge flow includes controls around fund movement, including validator-approved withdrawals and a built-in safety wait before withdrawals are completed. These controls form part of TxFlow's approach to protecting capital movement between networks, which represents one of the most important functions of financial infrastructure. The company previously completed a security audit of Bridge2 in 2026, connecting Arbitrum One to TxFlow L1, demonstrating continued commitment to strengthening security architecture as the network evolves.
Alongside continued development of TxFlow L1 and TxFlow DEX, the company is building two new ecosystem initiatives: TxFlow Builder Code. As reported by TxFlow, Builder Code is being developed to expand how builders and ecosystem participants can contribute to and grow alongside the network. These initiatives represent the next stage of ecosystem growth, providing more ways for traders to participate, more ways for builders to contribute, and more activity across the TxFlow network. For the TxFlow community, these developments support the broader objective of building a Layer 1 designed specifically for financial markets, bringing trading, liquidity, and financial applications onto one blockchain where all finance happens.
TxFlow L1 processes over 250,000 transactions per second (TPS) with one-block finality, according to the company's specifications. The network is built around TxFlow Improvement Protocol (TIP) Liquidity Standards that define how financial products are built, composed, and settled on-chain. Through its Channel architecture, TxFlow enables spot markets, derivatives, prediction markets, and future financial products to operate on the same chain while connecting to shared execution and settlement infrastructure. TxFlow DEX serves as the first application built on TxFlow L1, operating as a fully on-chain central limit order book for perpetual trading. The network is designed to be open, composable, and community-owned, with each new application strengthening the infrastructure available to those that follow.
