Core Bridge Capabilities
Our cross-chain bridge is engineered for financial institutions and high-volume protocols, delivering the security, speed, and reliability required for mission-critical asset transfers.
01
Multi-Sig MPC Security
Secure asset custody powered by a decentralized multi-party computation (MPC) network. Eliminates single points of failure and provides cryptographic proof for every transaction, ensuring funds are never at risk.

Cross-Chain Bridge Development FAQs
Get clear, specific answers to the most common questions CTOs and founders ask when evaluating a cross-chain bridge development partner.
Our standard deployment follows a 4-phase agile process and typically takes 6-10 weeks from kickoff to mainnet launch. Phase 1 (2 weeks): Architecture & smart contract design. Phase 2 (3-4 weeks): Core development, including bridge contracts and relayer logic. Phase 3 (2 weeks): Internal audit, testing, and integration. Phase 4 (1-2 weeks): Deployment and final security review. Complex multi-asset or custom consensus bridges may extend this timeline, which we scope and quote for upfront.
