In the race to focus on multi-chain identity solutions, a promising technical approach has been discovered. The portable on-chain identity verification scheme is quite interesting—one verification can generate a cryptographic identity credential, which is then stored in the wallet and seamlessly reused across more than 40 public chains.

This design addresses the pain point that Web3 users need to re-verify their identity every time they cross chains. There’s no need to repeat KYC or identity authentication on each chain; a single identity credential can circulate throughout the entire multi-chain ecosystem. For participants who want to build genuine on-chain reputation across different chains, this indeed lowers the barrier.

As the DeFi ecosystem becomes increasingly fragmented, a unified identity layer infrastructure is becoming more and more critical. For such cross-chain identity solutions to truly take off, it also depends on how many applications in the ecosystem are willing to adopt and recognize this system.
