CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155contracts with advanced features like vesting, staking, and governance. - DeFi Protocols: Automated market makers (AMMs), lending/borrowing pools, yield aggregators, and derivative contracts.
- Enterprise Logic: Multi-signature wallets, supply chain tracking, and asset tokenization with custom business rules.
We deliver battle-tested code with a focus on gas optimization and upgradeability patterns (like Transparent/UUPS Proxies) to protect your long-term investment.
Our engineers have deployed over 200+ contracts across EVM chains (Ethereum, Polygon, Arbitrum) and Solana, with a 100% security audit pass rate for major releases.

PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to integrating institutional-grade compliance into your StarkNet application, ensuring regulatory alignment without sacrificing performance.
01
Architecture & Compliance Blueprint
We conduct a deep-dive analysis of your application's data flows and user interactions to design a compliant architecture. This includes mapping regulatory requirements (e.g., AML, KYC, sanctions screening) to specific Cairo smart contract modules and off-chain services.

Off-Chain Service Integration
We seamlessly integrate enterprise-grade, API-first compliance providers (like Chainalysis, Elliptic, or Sumsub) with your StarkNet sequencer. This handles sensitive data off-chain while posting verified attestations on-chain for immutable audit trails.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your dApp or protocol.
We deliver audit-ready smart contracts on day one. Our code is built with Solidity 0.8+ and OpenZeppelin standards, featuring comprehensive unit tests and gas optimization. This means a faster, safer path to mainnet.
From tokenization to complex DeFi logic, we translate your business requirements into immutable, efficient on-chain code.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with minting, vesting, and governance modules. - DeFi & DEX: Automated Market Makers (AMMs), liquidity pools, staking, and yield farming contracts.
- Security First: Every contract undergoes internal review against common vulnerabilities before external audit.
