Hybrid Custody (On-Chain/Off-Chain) Design

We design and build integrated custody systems that combine the efficiency of on-chain smart contracts with the security and insurance backing of traditional off-chain custodial vaults for high-value tokenized assets.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 veterans for your token, DeFi, or NFT project.

We architect and deploy custom smart contracts on EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. Our development process is built for security and speed:

  • From concept to mainnet in 2-4 weeks for standard token or NFT contracts.
  • Gas-optimized code that reduces user transaction fees by up to 40%.
  • Full audit readiness with comprehensive documentation and OpenZeppelin security patterns.

We don't just write code; we deliver a secure, maintainable foundation for your on-chain product.

Our typical deliverables include:

  • Custom ERC-20, ERC-721, or ERC-1155 contracts with tailored minting, burning, and governance logic.
  • DeFi primitives like staking pools, liquidity vaults, and automated market makers (AMMs).
  • Upgradeable proxy patterns using TransparentProxy or UUPS for future-proofing.
  • Complete technical specs, deployment scripts, and a verification package for block explorers.

ENTERPRISE-GRADE SECURITY

Core Components of Our Hybrid Custody Architecture

Our modular architecture separates on-chain programmability from off-chain security, giving you the flexibility of self-custody with the institutional-grade protection of MPC. Each component is designed for production at scale.

01

Multi-Party Computation (MPC) Vaults

Off-chain private key management with distributed signing authority. Eliminates single points of failure and enables customizable approval policies (M-of-N) without exposing keys on-chain.

SOC 2 Type II
Compliance
FIPS 140-2
Hardware Security
02

Programmable Smart Contract Wallets

On-chain account abstraction (ERC-4337) wallets for seamless user interactions. Supports batched transactions, gas sponsorship, and custom recovery logic, all controlled by the MPC vault.

ERC-4337
Standard
< 2 sec
Tx Finality
03

Policy Engine & Transaction Orchestrator

Centralized logic layer that validates and routes transactions. Enforces compliance rules (AML, limits), manages gas optimization, and provides a unified audit trail across on/off-chain activity.

Cross-Chain Asset Bridge & Messaging

Secure, audited bridges and LayerZero/CCIP integrations for moving assets between supported chains. Maintains custody security during transfers with proof verification.

Real-Time Monitoring & Alerting

24/7 surveillance of all custody activity with configurable alerts for suspicious transactions, policy violations, and system health. Integrates with SIEM tools like Splunk and Datadog.

ARCHITECTED FOR SECURITY AND SCALE

Our Design and Development Process

A proven, end-to-end methodology to design and deploy secure, compliant, and scalable hybrid custody systems. We translate complex requirements into production-ready infrastructure.

01

Architecture & Threat Modeling

We begin with a comprehensive security-first design, mapping your asset flows and defining clear on-chain/off-chain boundaries. This includes threat modeling for key management, transaction signing, and regulatory compliance (e.g., travel rule).
