overview
CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built to your exact specifications.
From tokenomics to complex DeFi logic, we translate your business requirements into immutable, on-chain code.
- Custom Token Development:
ERC-20,ERC-721,ERC-1155, and bespoke token standards with tailored minting, vesting, and governance logic. - DeFi & dApp Logic: Automated market makers (AMMs), staking pools, lending protocols, and multi-signature wallets.
- Security & Auditing: Built with OpenZeppelin libraries, following formal verification patterns, and prepared for third-party audits by firms like CertiK or Quantstamp.
- Full Lifecycle Support: Development, testing on
testnets, mainnet deployment, and ongoing maintenance and upgrade management via proxy patterns.

BUILT FOR INSTITUTIONAL SCALE
Core Smart Account Infrastructure We Deliver
Our modular smart account stack provides the security, compliance, and performance required for high-value dark pool transactions. We deliver production-ready infrastructure, not just prototypes.
01
Multi-Signature Account Factory
Deploy custom ERC-4337 smart accounts with configurable M-of-N signing schemes. Supports hardware security modules (HSMs) and institutional key management systems for governance over fund movement.

Frequently Asked Questions
Get clear answers on how we build secure, compliant, and high-performance private trading infrastructure using ERC-4337 and MPC.
A fully functional, audited MVP for a private trading venue takes 4-8 weeks from kickoff to mainnet deployment. This includes smart contract development, integration of MPC key management, custom privacy logic, and a security audit. Complex order types or cross-chain settlement can extend this timeline, which we scope during the initial technical discovery phase.
