Circle Details CCTP Path for Non-USDC Tokens Across Supported Chains

TL;DR: Circle published technical guidance for issuer-controlled ERC-20 transfers using CCTP infrastructure beyond USDC. Its Arc demonstration is a testnet walkthrough, not a promise of universal production support. Circle has detailed how issuers can use its Cross-Chain Transfer Protocol infrastructure for assets other than USDC. A new developer guide describes token identity, burn-and-mint transfers and the controls that need to be configured before an ERC-20 can operate across supported networks. Circle published an October 30 developer guide explaining how the message and attestation infrastructure behind Cross-Chain Transfer Protocol can support issuer-operated ERC-20 assets beyond USDC.
