CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications, from concept to mainnet deployment.
From a single custom token to a complex DeFi protocol, we build the foundational logic your dApp relies on.
Our development lifecycle includes:
- Requirement Analysis & Architecture: Defining tokenomics, access control, and upgrade paths.
- Implementation in
Solidity/Rust: Using established patterns from OpenZeppelin and Solana Program Library. - Comprehensive Testing: Unit, integration, and fork testing on networks like Sepolia and Devnet.
- Security Audit Preparation: Code structured for seamless review by leading audit firms.
- Mainnet Deployment & Verification: One-click deployment scripts and contract verification on Etherscan/Solscan.
Typical deliverables for a 4-6 week engagement:
- Custom
ERC-20,ERC-721, orSPLToken with minting, vesting, and governance hooks. - Staking/Rewards Contract with time or liquidity-based reward distribution.
- Multi-signature Treasury or Vesting Wallet for team and investor funds.
- Full technical documentation and a deployment runbook for your team.

Core Capabilities of Our Screening Engine
Our engine delivers real-time, multi-jurisdictional sanctions screening with the precision and reliability required for institutional adoption. Built for the unique demands of blockchain transactions.
01
Real-Time On-Chain & Off-Chain Screening
Monitor wallet addresses, smart contracts, and counterparty data against global sanctions lists (OFAC, EU, UN) in real-time. We screen both blockchain-native data and traditional KYC/KYB information for a 360° risk view.
