USDC issuer Circle Internet Financial on Wednesday released a new method to move the major stablecoin between blockchains that it says is faster, safer and cheaper than the so-called “bridges” that pervade decentralized finance (DeFi).
Called the “Cross-Chain Transfer Protocol,” the technology debuts for USDC transfers between Ethereum and Avalanche, with more chains coming in the second half of 2023. DeFi apps can integrate the relevant smart contracts to make it easy for users to move their stablecoins about.
The tech attempts to break down the barriers currently fragmenting USDC’s $30 billion market cap across many different blockchains. Though Circle issues “native” USDC on many top ecosystems including Ethereum and Avalanche, those asset tranches were more or less partitioned; those who wanted to "bridge" the divide had to engage in complicated and sometimes expensive cross-chain transfers.
Circle’s new method seeks to replace bridges, which solved that problem by creating another: a derivative token called a wrapped asset. CCTP works by destroying USDC on the source chain and re-creating it on the destination chain.
The process could pay the biggest dividends when it comes to asset swaps. It could be used to move cross-chain and cross-token transfers behind the scenes.
“With CCTP, developers can simplify the user experience and their users can trust that they are always transacting with a highly liquid, safe and fungible asset in native USDC. This milestone makes USDC a natively multi-chain digital dollar,” Joao Reginatto, VP of Product said in a press release.
Wallet company MetaMask, bridge operator Wormhole and bridge aggregator LI.FI are among the infrastructure providers with CCTP coverage at launch.
Circle could not immediately be reached for comment.
