Circle Gateway Adds cirBTC and EURC Cross-Chain Support

| newsbtc.com
Circle Gateway has expanded beyond USDC to support cirBTC and EURC, giving developers a shared interface to access the same asset across supported blockchains. Each asset keeps a separate balance and does not convert automatically into another currency. Circle said Gateway transfers had exceeded $10 billion by mid-October 2026. Network support varies: cirBTC is available on Arc and Ethereum, while EURC is supported on Arc, Avalanche, Base, Ethereum, Solana and World Chain. Gateway’s advertised access in under 500 milliseconds applies after a balance is established; deposits must first reach finality on the source network. Funds are held in noncustodial GatewayWallet escrow contracts, while a separate withdrawal route that does not rely on Circle’s API has a seven-day delay. The underlying Bitcoin backing cirBTC is held by a regulated Circle entity, so users still rely on its custody of those reserves. Both assets can be used with Circle Nanopayments, although payments in assets other than USDC are limited to Ethereum Virtual Machine networks. Circle is waiving Gateway fees for cirBTC and EURC on Arc at launch. EURC is backed by euro reserves and complies with EU MiCA rules; cirBTC is backed 1:1 by Bitcoin. The expansion could simplify cross-chain payments and reduce businesses’ need to pre-fund multiple networks, but developers must check supported asset, network and payment combinations and account for deposit, withdrawal and settlement costs.
Neutral
The announcement is a product and infrastructure expansion, not a change to the monetary supply or backing of cirBTC or EURC. Broader Gateway access and Circle’s reported transfer volume above $10 billion could support use and liquidity over time, but the update alone does not establish a direct catalyst for either token’s market price. EURC is designed to track the euro, while cirBTC is backed 1:1 by Bitcoin, so their prices are primarily tied to their respective reference assets and the integrity of their reserves. In the short term, traders may respond to increased visibility or adoption, but any effect is likely to be limited unless transaction activity and demand rise materially. Network restrictions, deposit finality, fees and the seven-day independent withdrawal delay may also constrain immediate uptake. Longer term, smoother cross-chain access could improve utility and liquidity, while reliance on Circle’s custody of cirBTC’s underlying Bitcoin remains a consideration. On balance, the news is neutral for the prices of the mentioned tokens; it does not by itself imply a sustained bullish or bearish move.
