TxFlow Claims to Copy Hyperliquid's Bridge, API, and Naming
0xJaehaerys claims that TxFlow copied Hyperliquid's bridge and runs just 5 validators. TxFlow's founder and team member TaizeWang responded, stating that 838 out of 843 lines of TxFlow's verified bridge contract on Arbitrum are identical to Hyperliquid's Bridge2.sol. TxFlow claims to use Hyperliquid's bridge contract. The team also claims that TxFlow's consensus and matching engine are built in-house, while Hyperliquid's are closed source. TxFlow's public RPC lists 5 validators, but their identities are unknown. The article highlights that TxFlow uses a centralized exchange secured by a 3/4 multisig with a single key acting as the entire oracle, in contrast to Hyperliquid's open-source and validator-based system.
