Circle Gateway vs CCTP: Understanding the New Era of Cross-Chain USDC Infrastructure

TLDR: Gateway delivers sub-500 millisecond USDC access across chains, eliminating traditional rebalancing delays entirely. CCTP processes transfers in 8-20 seconds via Fast Transfer, suitable for periodic cross-chain rebalancing operations. Gateway maintains unified balances accessible simultaneously on multiple networks without fragmenting working capital. Both protocols employ non-custodial security with Gateway requiring dual signatures for instant access [...]
