LI.FI
LI.FI is a cross-chain liquidity aggregation and orchestration protocol that routes through bridges and exchanges. It is included because approval-related smart-contract vulnerabilities caused user-wallet losses in March 2022 and July 2024, while the protocol later resumed and continued expanding.
