Learn the key differences between bridged USDC and native USDC, along with step-by-step best practices for migrating to native USDC on the Aptos blockchain.
What Is Bridged USDC?
Bridged USDC is a synthetic version created when USDC is locked on one blockchain (e.g., Ethereum) and minted on another (e.g., Aptos) via third-party bridges like LayerZero. Unlike native USDC—issued directly by Circle and fully backed by cash reserves—bridged USDC (e.g., lzUSDC) carries dependencies on bridge security and lacks institutional redeemability.
Why Migrate to Native USDC?
- Regulatory assurance: Issued by Circle, a regulated entity.
- 1:1 redeemability: Backed by liquid cash equivalents.
- Interoperability: Compatible with Cross-Chain Transfer Protocol (CCTP).
