Circle Gateway adds cirBTC and EURC to its unified crosschain balances

Circle's Gateway now lets users hold one balance per asset across chains for its Bitcoin-backed token and euro stablecoin, not just USDC Circle has widened the scope of Gateway, its crosschain balance product. On October 23, 2026, the company added support for cirBTC and EURC , two assets that previously sat outside a system built around USDC . The pitch is simple. Instead of tracking separate piles of the same token on a dozen blockchains, a user holds one unified balance per asset and spends it wherever it’s needed. According to the research findings, funds become accessible in under 500 milliseconds once a deposit is finalized. The update also brings gas-free Nanopayments to cirBTC and EURC. Gas fees are the network charges users pay to process a transaction.
