overview
CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Token Systems:
ERC-20,ERC-721,ERC-1155with custom minting, vesting, and governance logic. - DeFi Protocols: Automated market makers (AMMs), staking pools, yield aggregators, and lending vaults.
- Enterprise Logic: Multi-signature wallets, access control systems, and verifiable on-chain records.
We don't just write code; we deliver secure, gas-optimized contracts that are ready for mainnet deployment and third-party audit.
Our development cycle includes comprehensive testing (unit, integration, fork), detailed documentation, and a clear handoff. Get a production-ready MVP in 2-4 weeks.

ENTERPRISE-GRADE INFRASTRUCTURE
Core Capabilities of Our EVM Payment Rails
We build dedicated, high-throughput payment corridors on EVM chains, delivering the reliability and compliance required for corporate finance. Our rails are engineered for scale, security, and seamless integration.
01
Multi-Chain Settlement Engine
Deploy a single payment system that operates across Ethereum, Polygon, Arbitrum, and Base. Our engine handles cross-chain asset bridging and settlement automatically, eliminating manual reconciliation.

EVM Payment Corridor Development
Frequently Asked Questions
Common questions from CTOs and founders about building secure, compliant cross-border payment systems on EVM chains.
A standard deployment from smart contract development to mainnet launch takes 4-6 weeks. This includes 2 weeks for core contract development and audit, 1 week for integration with your existing treasury/ERP systems, and 1-3 weeks for testing, compliance checks, and deployment. More complex multi-chain or heavily regulated corridors can extend to 8-10 weeks.
