CIRCLE GATEWAY LIVE ON MAINNET

Summary from the TLDR Crypto newsletter

Circle Gateway has launched on mainnet, offering a unified USDC balance that provides instant crosschain liquidity access in under 500 milliseconds across seven supported chains, including Arbitrum, Avalanche, Base, Ethereum, OP Mainnet, Polygon PoS, and Unichain. The platform combines smart contract infrastructure with an offchain attestation service to solve fragmented liquidity issues that force businesses to pre-position USDC across multiple chains, improving capital efficiency for payment service providers, exchanges, custodians, and wallets. Gateway operates on non-custodial principles where users retain control of their funds while enabling next-block speed transfers through user signatures combined with Gateway attestations. The solution targets businesses building at scale who need fast, capital-efficient settlement across chains without the operational overhead of managing chain-specific balances and rebalancing processes.
