ENTERPRISE-GRADE SECURITY & FLEXIBILITY
Core Features of Our Multi-Signature Sub-Accounts
Our multi-signature sub-account architecture provides granular control and institutional-grade security for managing treasury, payroll, and operational funds. Built for CTOs who need to delegate authority without compromising on-chain security.
01
Flexible M-of-N Signer Management
Configure custom approval thresholds (e.g., 2-of-3, 4-of-7) per sub-account. Add, remove, or replace signers with on-chain proposals. Ideal for adapting to team changes and governance requirements.

Frequently Asked Questions
Answers to common technical and commercial questions about our custom multi-sig sub-account development service.
Standard deployments take 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, unit/integration testing, and a security audit. Complex integrations (e.g., custom governance modules, cross-chain functionality) may extend to 6-8 weeks. We provide a detailed project plan with milestones during the initial scoping call.
