Bifrost x Hyperbridge: Scaling Polkadot's Liquid Staking Across Chains

Hong Kong -- Bifrost, the leading liquid staking appchain, has partnered with Hyperbridge, a next-gen interoperability coprocessor, to scale the adoption of Polkadot's largest Liquid Staking Token (vDOT) across EVM-compatible blockchains. Polkadot faces a challenge: a high staking rate but low liquid staking adoption, leaving DOT's yield potential largely untapped. This partnership integrates Bifrost's liquid staking techstack— SLPx with Hyperbridge's ZK-optimized interoperability layer, offering two key benefits: Sovereign Liquidity Flow: vDOT becomes the first liquid staking token natively compatible with both EVM and non-EVM chains, unlocking new liquidity for Polkadot and enabling cross-chain DeFi use cases. Protocol-Owned Security: All cross-chain operations inherit Polkadot's battle-tested consensus, ensuring security without external trust assumptions. Bifrost's SLPx simplifies multi-chain liquid staking by consolidating liquidity onto a single chain—eliminating the need to bootstrap vDOT liquidity across multiple ecosystems, reducing transaction fees, and improving efficiency. Hyperbridge, leveraging zkSNARKs and Merkle Tree-optimized state proofs, reduces proof size by over 90% while enabling batch verification. All validated block headers and historical states are permanently stored without requiring full-chain synchronization. This integration abstracts cross-chain complexity, allowing DOT holders to seamlessly stake to vDOT via Bifrost's non-custodial protocol and deploy liquidity across Base, Optimism, Arbitrum, and BNB Chain via Hyperbridge—transforming liquid-staked DOT into a yield-generating asset across ecosystems. As blockchain boundaries fade into the background, Bifrost and Hyperbridge are accelerating the future of frictionless, chain-agnostic decentralized finance, making true multichain liquidity a reality. Bifrost is a Liquid Staking Appchain tailored for all blockchains, utilizing decentralized cross-chain interoperability to empower users to earn staking rewards and DeFi yields with flexibility, liquidity, and high security across multiple chains. Hyperbridge is a coprocessor for secure, verifiable interoperability powered by consensus and storage proofs. It acts as the HTTPS of blockchain interoperability, providing developers with onchain and off-chain SDKs for securely sending cross-chain messages (POST requests) and reading on-chain storage (GET requests).
