Circle Adds Bitcoin-Backed cirBTC and Euro Stablecoin EURC to Its Gateway Service

Circle has expanded its Gateway service beyond USDC, adding support for Circle Wrapped Bitcoin (cirBTC) and its euro-backed stablecoin EURC, the company said in a blog post on Friday.

What changes

Gateway lets developers and businesses hold a single balance for an asset and use it on multiple blockchains, instead of keeping separate pools of funds on each network. Circle says that after a deposit finalizes, the funds can be accessed on other supported chains in under 500 milliseconds, though it notes timing is not guaranteed.

Under the expansion, cirBTC is supported on Arc and Ethereum. EURC works on Arc, Avalanche, Base, Ethereum, Solana and World Chain. Because Circle issues both tokens, it says Gateway can mint them directly on the destination chain rather than relying on a third party's inventory.

Circle also said its Nanopayments feature, which bundles many small payments off-chain and settles them in batches, now supports cirBTC and EURC. The company is pitching this at AI agents and pay-per-use services that make frequent small purchases.

Fees and scale

Gateway fees for cirBTC and EURC are waived on Arc at launch. Elsewhere, the fee is 1 basis point for those two assets, while USDC stays at 0.5 basis points. Circle says Gateway has processed more than $10 billion in volume, based on its internal data as of Oct. 23.

Why it matters

Liquidity split across many chains is a long-running pain point for exchanges, wallets and payment firms. Bringing bitcoin- and euro-denominated assets into the same system could make it easier to move value where demand appears, and it widens the role of non-dollar tokens in on-chain payments.
