Beforehand, Avalanche customers who held USDC on Ethereum needed to deposit their cash with a Circle associate or use a third-party bridge to switch their USDC from one community to the opposite. The brand new Cross-Chain Switch Protocol (CCTP) protocol seems to put off this want for USDC bridges.
The workforce launched a video on April 13 displaying how the brand new protocol works. In contrast to a conventional bridge, it doesn’t lock tokens despatched to its contract. As a substitute, it fully destroys them and points new tokens on the receiving community. Customers can redeem these new tokens for financial institution deposits immediately, by depositing the tokens with Circle or its companions.
Within the announcement, the workforce mentioned that it expects CCTP to resolve the issue of “fragmentation” within the Web3 ecosystem. At the moment, there are a number of unofficial variations of USDC floating round on varied networks, most of that are the results of tokens on one community being bridged to a different. Now that there’s an official option to switch cash from one community to a different, the workforce expects these unofficial copies to slowly decline in use, making the token much less complicated to make use of.
The workforce mentioned that most of the largest cross-chain protocols have already pledged to make use of CCTP going ahead, together with Celer, Hyperlane, LayerZero, LI.FI, MetaMask, Wormhole and others.
