Came across a post from Circle’s official account: Gateway, its cross-chain unified balance product, has added cirBTC and the euro stablecoin EURC alongside USDC, starting October 23.
Key details: Each asset has a unified balance, and once a deposit is confirmed, it becomes available across chains in under approximately 500 milliseconds, according to Circle. cirBTC is launching first on Arc and Ethereum; EURC is available on Arc, Avalanche, Base, Ethereum, Solana, and World Chain. It all uses the same Gateway API / Unified Balance Kit—no need to build a separate system. Gateway has processed over approximately $10 billion in total volume (internal data as of 10/23). Gateway fees for cirBTC/EURC on Arc are waived during the launch period; fees on other chains are 1 bp, while USDC remains at 0.5 bp.
Previously, you had to pre-position inventory on each chain. Now you can draw on it as needed—whether denominated in BTC, euros, or dollars, it all works through the same cross-chain balance model.
