The modular blockchain project $Avail has launched the Nexus Beta version. Nexus is a meta-interoperability protocol that solves the problem of blockchain fragmentation by connecting liquidity, assets, and coordination logic at the base layer. It runs on $Avail's decentralized public blockchain network, and cross-chain transactions are verified through a modular execution layer that supports zero-knowledge proofs, optimistic proofs, trusted hardware, and solver-based liquidity, enabling secure and seamless asset transfers across ZK chains, OP chains, and sovereign blockchains. Web3 application builders can now get early access to the Nexus SDK, allowing assets, users, and liquidity to flow freely within applications and between native chains. [Foresight News]
