Circle has announced the launch of developer service Circle Gateway, aiming to achieve unified $USDC balances, instant cross-chain liquidity, and other functions. It eliminates the need for cross-chain pre-funding or rebalancing, and can meet the needs of multiple chains with just one integration. Users retain full control and can withdraw without permission. It will be launched on the Base, Ethereum, and Avalanche testnets this month. [ChainCatcher]
