ENTERPRISE-GRADE SECURITY
Business Outcomes for Your Treasury or Fund
Our mobile bridge multi-signature scheme implementation delivers tangible security and operational improvements for managing high-value digital assets. We focus on measurable outcomes that protect capital and streamline governance.
01
Eliminate Single Points of Failure
Replace vulnerable single-key wallets with a distributed, mobile-based multi-signature scheme. Each transaction requires approval from a pre-defined quorum of authorized devices, drastically reducing the risk of theft from a compromised device or insider threat.

Accelerate Secure Decision-Making
Enable real-time transaction approvals from anywhere via mobile devices. Eliminate the delays of coordinating physical hardware wallets or in-person signings, allowing your treasury committee to act swiftly on time-sensitive opportunities without sacrificing security.

Frequently Asked Questions
Get clear answers on our implementation process, security, and support for your cross-chain bridge.
A standard implementation takes 4-8 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture design and smart contract development, 2-3 weeks for rigorous internal testing and security review, and 1-2 weeks for client-side integration and final audit. Complex requirements like custom governance or support for 10+ chains can extend the timeline.
