We architect and deploy production-grade smart contracts that form the unbreakable backbone of your application. Our development process is built on OpenZeppelin standards, comprehensive unit testing, and multiple audit cycles to ensure security and reliability from day one.
Web3 Banking API Suite
Smart Contract Development
Secure, gas-optimized smart contracts built by Web3-native engineers.
Deliver a secure, audited, and fully functional smart contract system in as little as 2-4 weeks.
Our team specializes in:
- Custom DeFi Logic: DEXs, lending protocols, yield strategies, and automated market makers (AMMs).
- NFT Innovation: ERC-721A, ERC-1155, and custom standards for gaming, membership, and digital assets.
- Enterprise Integration:
ERC-20tokenization, multi-signature wallets, and cross-chain bridges. - Gas Optimization: Expert-level Solidity to reduce transaction costs by 20-40% for your users.
We move beyond basic templates. Every contract is built with upgradability patterns (like Transparent Proxy), comprehensive event logging, and real-time monitoring integration with our Chainscore platform for post-deployment oversight.
Production-Ready Banking APIs
Deploy secure, compliant, and scalable banking APIs in weeks, not months. Our battle-tested infrastructure handles high-volume transactions with financial-grade reliability.
Real-Time Fiat On/Off-Ramps
Integrate global payment rails (SWIFT, SEPA, ACH) with crypto liquidity pools. Enable instant deposits and withdrawals with built-in AML/KYC compliance checks and fraud monitoring.
Multi-Chain Wallet Infrastructure
Secure, non-custodial wallet-as-a-service for EVM, Solana, and Bitcoin. Includes MPC key management, transaction simulation, and real-time balance/transaction APIs.
Programmable Treasury Management
APIs for automated crypto/fiat treasury operations: batch payments, multi-sig approvals, yield generation on idle assets, and real-time reconciliation.

Frequently Asked Questions
Get clear answers about our API suite for building compliant, scalable financial products on blockchain rails.
Typical integration takes 2-4 weeks from kickoff to production. For a standard implementation with fiat on/off ramps and wallet-as-a-service, we've seen clients go live in under 14 days. Complex deployments with multi-chain treasury management or custom compliance rules may extend to 6-8 weeks. We provide a detailed project plan during the discovery phase.
