overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts that form the backbone of your protocol. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and Solidity 0.8+ best practices. Every contract undergoes rigorous unit testing and a formal audit before mainnet deployment.

Deliver a secure, gas-optimized, and upgradeable foundation in as little as 2-4 weeks.

  • Token Standards: ERC-20, ERC-721, ERC-1155, and custom implementations.
  • DeFi Primitives: Automated Market Makers (AMMs), staking pools, yield strategies.
  • Governance Systems: DAO tooling, multi-sig wallets, and voting mechanisms.
  • Security Guarantee: All code is peer-reviewed and tested for common vulnerabilities.

PROVEN PROCESS

Our Delivery Methodology

We deliver secure, production-ready multi-signature vault off-ramps through a structured, transparent workflow designed for technical founders and CTOs. Our methodology ensures predictable timelines, rigorous security, and seamless integration with your existing financial stack.

01

Architecture & Design Sprint

We conduct a 2-day collaborative workshop to define your vault's governance model, signer structure, and withdrawal policies. We map out the complete technical architecture, including key management, transaction batching, and integration points with your custodians and exchanges.

2 days
Workshop Duration
1 week
Architecture Spec
02

Smart Contract Development & Audit

Our team builds custom, gas-optimized Solidity contracts (0.8.x+) using OpenZeppelin libraries. Every contract undergoes a formal security audit by a third-party firm like CertiK or Quantstamp before deployment, with findings remediated and verified.

03

Backend & API Integration

We develop the off-chain orchestration layer in Node.js/TypeScript, handling transaction queuing, signer coordination, and nonce management. We provide a RESTful API for initiating withdrawals, checking status, and managing signers, with comprehensive documentation and SDKs.

Staging Deployment & Penetration Testing

We deploy the complete solution to a staging environment (testnet + sandboxed backend) for integration testing. A dedicated penetration test is performed on the full system—contracts, API, and frontend—to identify and remediate any operational security vulnerabilities.

Smart Contract Development

Secure, audited smart contracts built for production by expert Solidity engineers.

We architect and deploy mission-critical smart contracts on EVM chains like Ethereum, Polygon, and Arbitrum. Our process delivers production-ready code in 2-4 weeks, from initial spec to final audit.

Every contract is built for security first, using battle-tested patterns from OpenZeppelin and rigorous internal review.

  • Full-Stack Development: End-to-end logic for ERC-20, ERC-721, staking, governance, and custom DeFi primitives.
  • Security & Audits: Multi-stage review culminating in a formal audit report from partners like Spearbit or CertiK.
  • Gas Optimization: We reduce deployment and transaction costs by 15-40% through efficient bytecode and storage patterns.

Frequently Asked Questions

Get clear answers on our secure, enterprise-grade off-ramp solution for managing treasury and user funds.

A standard deployment with a 3-of-5 multi-signature setup, integration with 2-3 major CEXs, and basic automation takes 2-4 weeks from kickoff to production. Complex requirements like custom governance, multi-chain support, or integration with proprietary settlement systems can extend this to 6-8 weeks. We provide a detailed project plan within the first week.
