Multi-Sig Integration with Legacy Finance Systems

We build secure, audited bridges connecting your on-chain multi-signature treasury to traditional banking, payment rails, and accounting software like QuickBooks and SAP.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your dApp.

We architect and deploy audit-ready smart contracts on EVM chains (Ethereum, Polygon, Arbitrum) and Solana. Our process delivers gas-optimized, upgradeable code with comprehensive testing, reducing your time-to-market to 2-4 weeks for an MVP.

  • Custom Logic: ERC-20, ERC-721, ERC-1155, DeFi protocols, DAOs, and bespoke business rules.
  • Security-First: Built with OpenZeppelin standards, formal verification, and peer review.
  • Full Lifecycle: Development, deployment, verification on Etherscan/Solscan, and post-launch monitoring.

We ensure your on-chain logic is a competitive asset, not a liability. Our contracts have secured over $50M+ in TVL for clients.

Business Outcomes for Your Treasury

Our multi-signature integration bridges your existing financial infrastructure with on-chain treasury management, delivering measurable security, efficiency, and control.

01

Enhanced Security & Reduced Counterparty Risk

Replace single points of failure with configurable multi-signature approval workflows. We implement M-of-N signing schemes (e.g., 3-of-5) using audited contracts like Safe{Wallet}, ensuring no single actor can move funds unilaterally.

PROVEN PROCESS

Our Delivery Methodology

Our structured, security-first approach ensures your multi-signature integration is delivered on time, on budget, and with enterprise-grade reliability.

01

Discovery & Architecture Design

We conduct a comprehensive audit of your existing finance stack to design a secure, scalable multi-sig architecture. This includes defining signer roles, transaction policies, and integration points with your core banking or treasury systems.

2-3 days
Initial Audit

Requirement Mapping
02

Smart Contract Development & Auditing

We build custom, gas-optimized multi-signature contracts using OpenZeppelin libraries. Every contract undergoes rigorous internal review and is submitted for a formal security audit by a leading firm like CertiK or Quantstamp before deployment.

Frequently Asked Questions

Common questions about integrating blockchain multi-signature security with your existing financial systems.

A standard integration with a legacy finance system (like SAP, Oracle, or a custom core banking platform) takes 4-8 weeks from kickoff to production deployment. This includes requirements analysis, smart contract development, API bridge creation, security audit, and final deployment. Complex integrations with multiple approval tiers or custom compliance logic may extend to 12 weeks.
