Chainlink also recently launched its CCIP cross-chain interoperability protocol, which will first be integrated on Avalanche, Ethereum, Optimism, and Polygon. Cross-chain has always been a hot topic, and it has been so for many years. Especially in the case of multi-chain, each protocol is relatively isolated within its own ecology and cannot be connected to each other. People have been proposing solutions to find solutions. For example, DOT’s parachains and cross-chain bridges, but cross-chain bridges are very risky. Many hacking incidents in 2021 and 2022 are related to cross-chain bridges. And CCIP can truly realize cross-chain dapp. For example, you can send some USDC from Ethereum to Optimism, and then once the transaction is over, you can exchange it for Ethereum through instructions and deposit it in the lending platform. The first Integrating this solution is Aave.
