Multichain (MULTI) on Ethereum was a protocol for cross-chain interoperability, originally launched as Anyswap in July 2020. It facilitated secure asset transfers across blockchain networks through a Secure Multi-Party Computation (SMPC) network. With services including bridging, routing, cross-chain messaging, and NFT support, MULTI served as a governance token within the ecosystem. In 2023, the project faced critical disruptions: CEO Zhao Jun was reportedly arrested in China, leading to infrastructure issues, and a subsequent security exploit resulted in the unauthorised transfer of $126 million. The protocol was shut down in July 2023, leaving the Ethereum-based MULTI token as a historical asset without active functionality.
