A deep dive into the design of a certain cross-chain lending protocol truly opened up new ideas. Traditional DeFi lending is limited by single-chain islands, with liquidity dispersed and assets not interoperable, leading to significant efficiency losses. This protocol approaches the problem from a different angle—through a full-chain credit system, enabling assets like ETH and USDC to be transferred and allocated efficiently across multiple blockchains. After users deposit assets on Chain A, they can immediately access liquidity support on Chain B and Chain C, completely breaking down the barriers between chains. This cross-chain protocol design is indeed worth paying attention to, as it addresses the core issue of DeFi efficiency in the multi-chain era.
