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.
Multi-Sig Integration with Legacy Finance Systems
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your dApp.
- Custom Logic:
ERC-20,ERC-721,ERC-1155, DeFi protocols, DAOs, and bespoke business rules. - Security-First: Built with
OpenZeppelinstandards, 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.
Core Integration Capabilities
We deliver the foundational components required to securely connect your existing financial infrastructure with on-chain multi-signature protocols, ensuring compliance, control, and capital efficiency.
Legacy System API Adapters
Pre-built, secure connectors for core banking platforms (FIS, Fiserv, Temenos), ERP systems (SAP, Oracle), and treasury management software, enabling real-time balance and transaction data flow.
Compliance & Audit Trails
Automated logging of all multi-sig proposal creation, approvals, and executions with immutable on-chain proofs, mapped to internal user IDs for seamless SOX and financial audit readiness.
Custodial Key Management
Enterprise-grade MPC (Multi-Party Computation) or hardware security module (HSM) integration for private key generation, storage, and signing, eliminating single points of failure.
Custom Approval Workflows
Configure complex, role-based approval policies (M-of-N thresholds, hierarchical approvals, time-locks) that mirror your internal financial controls and governance.
Real-Time Monitoring & Alerts
24/7 dashboard and webhook alerts for pending proposals, successful executions, and failed transactions, integrated with tools like PagerDuty, Slack, and Microsoft Teams.
Gas Optimization & Batching
Intelligent transaction batching and gas fee management for EVM and non-EVM chains, reducing operational costs by up to 40% compared to manual single-transaction processes.
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.
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.
Automated Reconciliation & Real-Time Audit Trail
Eliminate manual spreadsheet tracking. Our integration provides an immutable, on-chain ledger for all treasury transactions, automatically syncing with your ERP (e.g., NetSuite, SAP) for real-time balance visibility and simplified financial reporting.
Accelerated Settlement & Operational Efficiency
Execute payroll, vendor payments, and treasury swaps in minutes, not days. Bypass traditional banking delays by settling directly on-chain with programmable logic, reducing operational overhead and freeing up capital.
Programmable Treasury Policies & Compliance
Enforce corporate governance automatically. We codify spending limits, approval hierarchies, and transaction whitelists directly into smart contracts, ensuring policy compliance is built into every transaction without manual oversight.
Seamless Integration with Legacy Systems
Connect securely to your existing banking APIs, accounting software, and internal tools without disrupting workflows. We build custom adapters and provide a unified dashboard, abstracting blockchain complexity for your finance team.
Yield Optimization on Idle Capital
Safely generate returns on treasury reserves. Our integration facilitates secure, policy-governed deployments into institutional-grade DeFi protocols (e.g., Aave, Compound) directly from your multi-sig, with real-time performance reporting.

Our Delivery Methodology
Our structured, security-first approach ensures your multi-signature integration is delivered on time, on budget, and with enterprise-grade reliability.
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.
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.
Secure Backend Integration
Our engineers develop the secure middleware that connects your multi-sig wallets to legacy systems (e.g., SAP, Oracle, SWIFT). We implement event listeners, transaction signer APIs, and non-custodial key management solutions.
Staged Deployment & Testing
We deploy to a testnet environment first, executing full integration tests and a UAT phase with your finance team. We then manage the mainnet deployment using secure, scripted processes with full rollback capabilities.
Compliance & Monitoring Setup
We configure real-time dashboards for transaction visibility, implement automated compliance checks (OFAC, AML), and set up alerting for multi-sig proposals, approvals, and execution events.
Knowledge Transfer & Support
We provide comprehensive documentation, admin training for your team, and ongoing technical support. This includes a detailed runbook for operational procedures and escalation paths.
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.
