overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications.

We architect and deploy production-grade smart contracts that power your core business logic. Our development process is built for security and speed, delivering audit-ready code in 2-4 weeks.

  • Full-Stack Expertise: Solidity/Rust development for EVM, Solana, and other L1/L2 networks.
  • Security-First: Contracts built with OpenZeppelin patterns and undergo internal review before formal audit.
  • Gas Optimization: Every line is written for minimum transaction cost and maximum efficiency.

We don't just write code; we deliver the secure, on-chain foundation your product needs to launch with confidence.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for your specific business logic and audited for enterprise deployment.

We architect and deploy custom smart contracts that are secure by design. Every contract is built with Solidity 0.8+, follows OpenZeppelin standards, and undergoes rigorous internal audits before delivery. We focus on gas efficiency, upgradability patterns, and comprehensive test coverage exceeding 95%.

  • Token Systems: Custom ERC-20, ERC-721, and ERC-1155 implementations with advanced features like vesting, minting controls, and multi-chain compatibility.
  • DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking mechanisms, and yield aggregators with battle-tested security patterns.
  • Enterprise Logic: Multi-signature wallets, DAO governance modules, supply chain tracking, and custom business logic for real-world asset tokenization.

We deliver a fully documented, deployable package in 2-4 weeks, including audit reports and a deployment roadmap for mainnet launch.

Account Abstraction Vault-Wallet Integration

Frequently Asked Questions

Get clear, technical answers to common questions about integrating smart contract wallets with institutional-grade vaults.

A standard integration, connecting a custom ERC-4337 smart account to a custody solution like Fireblocks or Copper, takes 2-4 weeks from kickoff to mainnet deployment. Complex multi-signature setups or novel recovery mechanisms can extend this to 6-8 weeks. We follow a phased delivery model with weekly demos.
