overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect and deploy custom smart contracts that are secure, gas-optimized, and tailored to your specific business logic. Our development process ensures audit-ready code from day one, reducing time-to-market and technical debt.

  • Security-First Development: Built with Solidity 0.8+ and OpenZeppelin libraries, following industry-standard security patterns.
  • Full-Spectrum Contracts: From fungible ERC-20 tokens and ERC-721/1155 NFTs to complex DeFi protocols and DAO governance systems.
  • End-to-End Delivery: We handle everything from initial architecture and development to deployment, verification on Etherscan, and post-launch support.

Deploy with confidence. We deliver contracts that pass rigorous internal audits and are built for mainnet resilience and long-term maintainability.

Core Capabilities of Our Fiat-to-Stake API

A purpose-built API suite designed for FinTechs and Web3 platforms to seamlessly convert user fiat deposits into staked crypto assets, reducing development time and compliance overhead.

01

Direct Fiat-to-Stake Settlement

Convert user deposits from major payment rails (Visa, Mastercard, SEPA) directly into staked positions on Ethereum, Solana, or Polygon. Eliminates the multi-step process of on-ramping, transferring, and staking, reducing user drop-off by up to 70%.

Frequently Asked Questions

Get clear answers on timelines, security, and process for integrating a compliant fiat-to-stake solution.

A standard integration takes 2-4 weeks from kickoff to production launch. This includes KYC/KYC provider setup, smart contract deployment, and end-to-end testing. Complex requirements like custom staking logic or multi-chain support may extend this to 6-8 weeks. We provide a detailed project plan during the initial technical discovery call.
