Multi-Signature Wallet Development

Deploy a unified multi-sig solution across EVM chains (Ethereum, Polygon, Arbitrum) and beyond. Manage ERC-20, ERC-721, native tokens, and protocol-specific assets from a single governance interface.

Implement complex policies: scheduled executions, batch transactions, and role-based permissions. Features include transaction simulation, nonce management, and real-time status dashboards for signers.

Built-in immutable logging for all proposal creation, approvals, rejections, and executions. Generate comprehensive reports for internal audits and regulatory compliance (travel rule, AML).

Full lifecycle support: deployment scripts, upgradeability patterns using proxies, and 24/7 monitoring with alerts for suspicious activity or failed transactions. Includes disaster recovery planning.

Mitigate single points of failure with custom multi-sig configurations (M-of-N). We implement battle-tested smart contracts with formal verification and comprehensive audit trails for every transaction.

Replace manual, error-prone processes with automated, on-chain approval workflows. Define custom roles, spending limits, and transaction policies to enforce internal controls programmatically.

Build with compliance in mind. Our wallets support transaction memos, on-chain attestations, and integration-ready logs for simplified reporting to auditors and regulators.

Deploy a production-ready, white-labeled multi-sig solution in weeks, not months. Our modular architecture integrates seamlessly with your existing dApp, DAO tools, or custody platform.

Eliminate the cost and complexity of managing custom security infrastructure. We provide 24/7 monitoring, incident response, and smart contract upgrade management as part of our service.

Built on upgradable proxy patterns (ERC-1967) and modular signing logic. Easily adapt to new signature schemes (ERC-1271), L2s, and institutional standards without migrating assets.

We begin with a formal threat model, identifying attack vectors and designing a secure architecture using battle-tested patterns from Gnosis Safe and OpenZeppelin. This upfront rigor prevents costly vulnerabilities later.

Our engineers write custom, gas-optimized Solidity contracts (0.8.x+) with comprehensive unit and integration tests. We implement modular, upgradeable logic for roles, permissions, and transaction flows.

We manage the secure deployment to mainnet and testnets, and assist with initial signer setup. We provide best-practice guides for operational security, key generation, and hardware wallet integration.

Post-launch, we implement real-time monitoring for anomalous transactions and failed signatures. Our team provides 24/7 on-call support with defined SLAs for emergency response and upgrades.

We deliver complete technical documentation, admin guides, and integration APIs. The final handoff includes a security runbook and training for your team to ensure full operational ownership.
