EVM Multi-Signature Dashboard Development

Compose, simulate, and batch transactions across Ethereum, Polygon, Arbitrum, and other EVM chains from a single interface. Supports complex multi-step operations like cross-chain bridging, staking, and treasury management.

Implement fine-grained access control for signers. Define roles (e.g., Treasurer, Approver, Viewer), set spending limits per role, and require M-of-N approvals based on transaction type, amount, or destination.

Monitor all wallet activity with an immutable, searchable audit trail. Every proposal, signature, rejection, and execution is logged with timestamps, signer IDs, and on-chain transaction hashes for full compliance.

Advanced features to minimize costs and streamline execution. Includes EIP-1559 fee estimation, batch transaction gas savings, and the ability to schedule future executions or set conditional triggers.

Streamlined workflow for adding/removing signers with mandatory multi-sig approval. Integrates with hardware wallets (Ledger, Trezor), MPC solutions, and supports social recovery mechanisms for lost keys.

Replace vulnerable single-key wallets with configurable M-of-N approval policies. We implement battle-tested smart contracts (like Safe{Wallet} or custom-built) with role-based access control, ensuring no single actor can move funds unilaterally.

Automate batch payments, payroll, and vendor disbursements through a unified dashboard. Our development reduces manual transaction signing from hours to minutes, with built-in scheduling and transaction queuing.

Gain immutable, on-chain logs for every proposal, approval, and execution. We build comprehensive dashboards that provide real-time visibility into fund flows, signer activity, and policy adherence for internal and external auditors.

Integrate secure, multi-sig controlled wallets directly into your dApp or protocol. Our APIs and SDK integrations enable features like managed user funds, DAO treasuries, and institutional custodial services without rebuilding security from scratch.

Demonstrate robust security practices to insurers and stakeholders. Our implementations follow OpenZeppelin standards and can include formal verification, reducing the attack surface and potentially lowering custody insurance premiums.

Build with institutional-grade features from day one: MPC key management integration, hardware security module (HSM) support, and compliance hooks for sanctions screening. We architect for scale and regulatory evolution.

We design modular, upgradeable smart contracts using OpenZeppelin's Governor and TimelockController patterns. Our architecture separates logic from data, enabling future upgrades without compromising security or user funds.

Every contract undergoes rigorous internal review and automated testing (Slither, MythX) before submission to leading third-party auditors. We prioritize findings from critical to low and provide detailed remediation reports.

We build responsive dashboards with React/Next.js and ethers.js/Viem, implementing batched transactions and gas estimation to minimize user costs. Real-time blockchain event listeners ensure UI state is always synchronized.

Implement granular permission systems for proposers, executors, and signers. Configure custom voting strategies (token-weighted, NFT-based) and quorum requirements tailored to your DAO or corporate structure.

Full-stack testing suite using Hardhat/Foundry for contracts and Cypress/Playwright for the frontend. Automated deployment pipelines with version pinning ensure consistent, repeatable releases to testnet and mainnet.
