How to Transfer USDC Between Chains Without a Bridge (2026)
Circle's CCTP burns native USDC on the source chain and mints native USDC on the destination, so you still hold Circle-issued USDC at the end. This 2026 guide covers burn-and-mint versus lock-and-mint, Fast versus Standard Transfer, and what to confirm before you move funds.
