This year, the cross chain bridge market has surged in popularity, but there are structural changes hidden behind the prosperity. Data shows that since September 2024, cross chain transaction volume has climbed from $18.6 billion to a new high of $56.1 billion in July of this year, driven by a significant increase in the size of individual funds - the average transaction volume has risen from $1051 to $3489- while the number of transactions has remained relatively stable. This means that the market is shifting from high-frequency, small-scale interactions to large-scale capital deployment. Ethereum remains the largest capital hub, with a net inflow of $10.1 billion this year, almost eight times that of the second ranked Sonic; Base recorded a net outflow of $5 billion, mainly flowing towards Ethereum. Starknet's cross chain activity is exceptionally active, with transaction volume about half that of Ethereum. At the protocol level, LayerZero maintains its position as the leader in messaging protocols with a monthly transaction volume of $4.965 billion, while CCTP benefits from USDC demand ranking second, followed closely by Wormhole and Hyperlane. In terms of application layer, Hyperliquid topped the list due to the demand for stablecoin deposits and withdrawals, while USDT0 ranked second due to statistical caliber. The core competition is concentrated in the three major protocols of Across, Stargate, and deBridge: Across focuses on "DEX one click cross chain coin exchange", with a monthly transaction volume of 1.4 billion US dollars and support for 19 chains; Stargate relies on LayerZero and achieves 80 chain coverage through the Hydra mechanism, and is facing a $110 million acquisition proposal from LayerZero; DeBridge ensures network security through independent validators, with quarterly revenue exceeding $2 million, and repurchases all protocol revenue from DBR. The cross chain bridge track has entered a new stage of "large-scale flow+technological differentiation", and the flow pattern of large market funds is being reshaped. The competition for core protocols has upgraded from a competition for traffic to a comprehensive competition of technology, ecology, and profit models.
