According to CoinMeta, Circle has announced that its cross-chain balance service Gateway now supports cirbtc and eurc. Developers can use a unified interface to transfer these three assets. Each asset maintains its own independent balance, and deposits made into eurc will not be used to fund cirbtc withdrawals or automatic currency conversions. This feature is currently limited to the ARC and Ethereum networks and supports ARC, Avalanche, Base, Ethereum, Solana, and World Chain. Cross-chain access times after setting up a balance are less than 500 milliseconds, and deposits are stored in non-trusted Gateway Wallet custody contracts. There is also an alternative withdrawal route that does not rely on API, but withdrawals have a 7-day delay. The new assets are compatible with Nanopayments batch settlement, and the Nanopayments for non-USDC assets is only available on the EVM network. During the launch period, Circle will waive Gateway fees for transactions between ARC and cirbtc and eurc.
