Institutional-Grade Treasury Custody Smart Contracts

Implement M-of-N approval workflows with configurable signer roles (Admin, Treasurer, Auditor). Supports timelocks, spending limits, and role-based access control (RBAC) for precise fund management.

Built on upgradable proxy patterns (Transparent/UUPS) with OpenZeppelin Defender for secure admin operations. Includes pause mechanisms and emergency asset recovery modules.

Native custody for EVM chains (Ethereum, Polygon, Arbitrum) with secure bridging integrations. Manage ERC-20, ERC-721, and wrapped native assets from a single governance interface.

Automated on-chain event logging and integration with accounting platforms. Provides immutable audit trails for all transactions, approvals, and governance actions.

Contracts are optimized for minimal gas consumption on deployments and frequent operations. Features batch transactions and gas abstraction to reduce operational overhead.

Designed for regulatory compliance with built-in features for address screening (OFAC), transaction monitoring, and seamless integration with third-party audit tools.

Every custody contract undergoes formal verification and audits by leading firms like Trail of Bits and Quantstamp. We guarantee mathematical proof of correctness for core logic, eliminating reentrancy and overflow vulnerabilities.

Implement granular, role-based governance with configurable approval thresholds (M-of-N), time-locks, and transaction policies. Enforce compliance rules directly on-chain for treasury operations.

Our contracts are built with institutional transaction volumes in mind. We deliver up to 40% lower gas costs for batch operations and complex approvals compared to standard implementations.

Future-proof your treasury with a modular design using EIP-2535 Diamonds or transparent proxies. Safely upgrade logic, add modules, or integrate new assets without migrating funds.

Manage a unified portfolio of ERC-20, ERC-721, ERC-1155 tokens, and native ETH within a single custody framework. Includes support for staking, vesting, and wrapped assets.

We begin with a formal threat model, identifying attack vectors and designing a modular, upgradeable architecture. This proactive security analysis prevents costly redesigns later.

Contracts are built in Solidity 0.8+ using OpenZeppelin libraries. Every line follows best practices for access control, reentrancy guards, and gas optimization to minimize risk and cost.

Our team conducts a rigorous internal audit, complemented by comprehensive unit, integration, and fuzz testing. We target >95% branch coverage before external review.

All custody contracts undergo a mandatory audit by a top-tier, independent security firm. We facilitate the process and manage remediation to ensure zero critical issues at launch.

We manage the secure deployment on your chosen network (Ethereum, Polygon, Arbitrum), verify all contract source code on Etherscan, and conduct final integration tests.

Post-launch, we provide guidance on setting up real-time monitoring for anomalous transactions and establish a clear incident response playbook for your security team.
