ARCHITECTURE
Engineered for Liquid Staking Token Dynamics
Our bridge is purpose-built for the unique security, composability, and economic demands of liquid staking tokens (LSTs), ensuring your protocol's core assets are never at risk.
01
Non-Custodial Asset Security
LSTs remain in user-controlled wallets. Our bridge uses canonical token mapping and verifiable proofs, eliminating the counterparty risk of wrapped or synthetic assets.

Multi-Chain Yield Preservation
Maintain staking rewards while bridging. Our system tracks underlying validator yields and ensures accurate reward distribution on the destination chain, preserving LST economics.

Composability-First Design
Bridged LSTs are native, canonical assets that integrate seamlessly with DeFi primitives (DEXs, lending markets) on the destination chain, maximizing utility and liquidity.

PROVEN FRAMEWORK
Our Development & Security Methodology
We deliver secure, scalable multi-chain bridges through a rigorous, battle-tested process that prioritizes your asset security and time-to-market.
01
Architecture & Design Review
We begin with a comprehensive audit of your existing staking and bridge logic, identifying architectural risks and optimizing for gas efficiency and cross-chain interoperability before a single line of code is written.

Technical & Commercial Considerations
LST Bridge Development: Key Questions
Answers to the most common questions from CTOs and technical founders evaluating a multi-chain LST bridge.
A standard, production-ready LST bridge deployment takes 2-4 weeks from finalized specifications to mainnet launch. This includes core bridge contract development, integration with your staking protocol, security audits, and deployment to your target chains (e.g., Ethereum, Arbitrum, Polygon). Complex multi-chain deployments with custom governance or reward mechanisms may extend to 6-8 weeks.
