CCTP (Cross-Chain Transfer Protocol)
A protocol that enables native USDC transfers between blockchains by burning tokens on one chain and minting them on another.
CCTP solves a big problem with traditional bridges. Normally, moving USDC between chains means using a bridge that locks your tokens and gives you a "wrapped" version. If that bridge gets hacked, the wrapped tokens become worthless.
CCTP works differently. It burns your USDC on the source chain and mints new, native USDC on the destination chain. There's no wrapping, no locked pools, no bridge risk. The USDC on both sides is real, native USDC backed by the same reserves.
CCTP supports transfers between Ethereum, Base, Arbitrum, Optimism, Solana, Avalanche, and several other chains. It's the safest way to move USDC across chains.
