EVM Multi-Signature Wallet Development

Implement M-of-N, role-based, or time-locked approval workflows. Configure custom quorums (e.g., 3-of-5 signers) and hierarchical permissions to match your governance structure precisely.

Deploy your multi-sig on Ethereum, Polygon, Arbitrum, Optimism, or Base. We architect solutions for managing assets across chains from a single interface.

Every transaction proposal, approval, rejection, and execution is immutably logged on-chain and presented in a clear dashboard for full transparency and regulatory compliance.

RESTful and WebSocket APIs to programmatically create proposals, check statuses, and sign transactions. Includes webhook alerts for pending approvals.

Implement custom multi-signature logic with configurable M-of-N approval thresholds, timelocks, and role-based permissions to eliminate single points of failure in your DAO's treasury management.

Automate proposal execution with on-chain voting integration (e.g., Snapshot, Tally) and batch transaction capabilities, reducing administrative overhead and proposal-to-action time.

Deploy battle-tested smart contracts built with OpenZeppelin libraries and undergo formal verification or third-party audits (e.g., CertiK, ConsenSys Diligence) to mitigate financial and reputational risk.

Leverage our pre-audited modular components and deployment frameworks to launch a custom, secure multi-sig wallet for your DAO in weeks, not months.

Build multi-sig solutions with native support for EVM-compatible L2s (Arbitrum, Optimism) and sidechains (Polygon), enabling unified governance across your DAO's multi-chain assets.

Integrate with familiar front-end frameworks (React, Vue) and provide comprehensive documentation, reducing the learning curve for your team and DAO members.

We start with a deep technical deep-dive to define your exact requirements: signer policies, governance flows, and integration points. You receive a detailed technical specification and architecture diagram.

Our engineers write custom, gas-optimized Solidity contracts (0.8.19+) using OpenZeppelin libraries. We implement your multi-signature logic, access controls, and upgrade patterns from day one.

Every line of code undergoes rigorous unit, integration, and scenario testing. We conduct an internal security review against common vulnerabilities before recommending third-party audits.

We build a responsive admin dashboard for managing signers and proposals, plus a developer-friendly SDK (TypeScript) for seamless integration into your existing dApp or platform.

We handle the secure deployment to your chosen EVM network (Ethereum, Polygon, Arbitrum, etc.), contract verification on Etherscan, and provide a comprehensive deployment report.

You receive complete source code, documentation, and operational runbooks. We offer post-launch support packages for maintenance, upgrades, and scaling to additional networks.
