ENTERPRISE-GRADE PROTECTION
Operational Security and Governance Control
Multi-signature bridge custody requires more than basic smart contracts. We deliver institutional-grade security frameworks and governance tooling designed for the high-stakes environment of prediction markets, where asset movement must be secure, transparent, and compliant.
01
Custom Multi-Sig Governance Frameworks
We design and deploy bespoke multi-signature schemes (e.g., M-of-N, time-locks, role-based permissions) tailored to your governance model. This ensures no single point of failure and enforces consensus for all bridge operations.

Multi-Sig Bridge Custody: Key Questions
Technical leaders building cross-chain prediction markets ask us these questions about secure, multi-party bridge custody. Get specific answers on timelines, security, and integration.
A production-ready, audited multi-sig bridge for a prediction market typically deploys in 3-5 weeks. This includes a 2-week core development sprint for the Solidity contracts and front-end integration, followed by a 1-2 week internal and external security audit cycle. We've delivered bridges for 12+ prediction platforms, with the fastest deployment to mainnet in 18 days.
