Multi-Signature Wallet with Hardware Integration

Native support for EVM chains (Ethereum, Polygon, Arbitrum) and non-EVM (Solana, Cosmos) with a unified interface for managing ETH, ERC-20s, NFTs, and native tokens across networks.

Define and enforce complex spending rules, velocity limits, and whitelists directly in the smart contract logic, automating compliance and reducing manual oversight.

Automated generation of transaction reports, signer attestations, and audit-ready logs for accounting (FASB/IAS) and regulatory compliance (Travel Rule, AML).

Distribute transaction authority across multiple hardware security modules (HSMs) and personnel. No single compromised key can move funds, protecting against insider threats and external attacks.

Define approval workflows with role-based permissions. Automate routine payments and set spending limits, reducing administrative overhead for finance teams by up to 70%.

Built-in audit trails log every transaction proposal, signature, and execution. Generate immutable reports for SOC 2, ISO 27001, and financial audits directly from the platform.

Simulate transactions before signing to prevent costly errors. Batch operations and optimize gas fees, achieving up to 40% savings on high-frequency settlement costs.

Integrate programmable wallet logic via our API/SDK in under 2 weeks. Supports EVM chains (Ethereum, Polygon, Arbitrum) and Solana for multi-chain strategies.

Modular architecture supports integration with existing custody providers (Fireblocks, Copper) and can be upgraded for new signature schemes (ERC-4337, MPC).

We define the multi-signature policy (M-of-N), key management strategy, and hardware integration architecture (Ledger, Trezor, YubiKey) based on your specific security and operational requirements.

Implementation of audited, gas-optimized multi-signature contracts (e.g., Safe, custom Gnosis) with support for ERC-20/721/1155 assets, batch transactions, and custom authorization logic.

Secure integration with hardware security modules (HSMs) and wallet providers (Ledger, Trezor) for offline key generation, signing, and transaction approval flows within your application.

Build a user-friendly admin dashboard and developer SDK for managing signers, proposing transactions, and executing approvals with clear audit trails and real-time status.

Comprehensive review of smart contracts, API endpoints, and integration layers by our internal security team, following industry-standard practices before mainnet deployment.

We handle the deployment to your chosen network (Ethereum, Polygon, Arbitrum, etc.), configure monitoring, alerting, and provide documentation for ongoing maintenance.
