Circle Gateway is now available on HyperEVM from Hyperliquid, Sei, Sonic, and World Chain āœ… Non-custodial, chain-abstracted USDC āœ… Frictionless, instant crosschain UX āœ… Enables capital-efficient treasury management āœ… One integration for on-demand liquidity across 11 supported chains Gateway is built on a core primitive: decoupling source chain block finality from crosschain settlement. Once USDC is deposited into Gateway from any supported chain, Gateway consolidates your balances across chains into a unified USDC balance. Use your chain-abstracted USDC instantly when and where itā€™s needed for DeFi, payments, treasury rebalancing, and more. This is a new crosschain paradigm. Now available on Arbitrum, AvalanchešŸ”ŗ, Base, Ethereum, HyperEVM from Hyperliquid, Optimism, Polygon, Sei, Sonic, Unichain, and World Chain with more blockchains expected. Start building today:

Today, we are introducing the Unified Balance Kit! It is a TypeScript SDK within App Kits that is built on top of Circle Gateway, a protocol that enables a unified USDC balance across supported blockchains and handles the underlying crosschain movement of funds when spending. Instead of stitching together different routing logics, developers can use this SDK to deposit, view, estimate, and spend from a unified USDC balance. Try it out yourself!

Today, Circle announced the launch of Gateway on mainnet, a major step forward in solving one of the biggest operational and UX challenges with stablecoins: wallet and chain fragmentation. Weā€™re proud that Blockradar is live as a Day 1 partner, integrating Gateway directly into our infrastructure to bring this to fintechs everywhere. For us, this is a glimpse of what happens when infrastructure does the heavy lifting so operators and users donā€™t have to. Funds are programmatically unified into one USDC balance, reducing reconciliation headaches and simplifying the customer experience. Together with Gateway, stablecoins move one step closer to mainstream rails. Access Gateway here: See how it looks in action ā¬‡ļø
