CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by experts to power your Web3 application.
- Full Lifecycle Support: From initial design and
ERC-20/721/1155implementation to deployment, verification, and ongoing maintenance. - Security-First Approach: Every contract undergoes internal audits and formal verification before deployment to mainnet.
- Gas Optimization: We write efficient code to minimize transaction costs for your users, a critical factor for adoption.
- Integration Ready: Contracts are built with clear interfaces for seamless connection to your frontend and backend systems.
Deliver a secure, auditable, and performant smart contract system in as little as 2-4 weeks, reducing your technical risk and accelerating time-to-market.

ENTERPRISE-GRADE SECURITY
Core Capabilities of Your Custom Vault
Our Multi-Signature Payment Vault & Policy Engine is engineered for CTOs who cannot compromise on security or operational control. We deliver battle-tested infrastructure that automates treasury management with programmable governance.
01
Programmable Policy Engine
Define and enforce granular spending rules (e.g., tx.value < 5 ETH && signerCount >= 3/5). Automate approvals for recurring payments, payroll, and vendor settlements without manual intervention.

Frequently Asked Questions
Get clear answers on deployment, security, and support for our enterprise-grade treasury management solutions.
Standard deployments take 2-4 weeks from kickoff to mainnet launch. This includes requirements finalization, smart contract development, policy configuration, and a full security audit. Complex integrations with existing ERP or accounting systems can extend the timeline, which we scope and agree upon upfront.
