According to a report by CoinDesk on June 3, the staking protocol Symbiotic has launched the Relay software development kit (SDK), which allows developers to stake assets on Ethereum and verify staking status on any blockchain. Relay serves as a universal version of Symbiotic’s restaking technology, supporting the construction of a secure coordination layer for cross-chain decentralized applications. Algys Ievlev, co-founder of Symbiotic, said the technology solves the long-standing security verification challenges faced by developers of multi-chain protocols without relying on trusted relayers or custom infrastructure. By connecting to the Symbiotic network, Relay enables developers to configure cross-chain verification mechanisms and support the construction of bridges, oracles, and other applications secured by real equity. This technology is expected to become a new standard for cross-chain protocol coordination, ensuring security and reducing development complexity.
