CORE INFRASTRUCTURE

Custom Smart Contract Development

Secure, production-ready smart contracts built for your specific business logic and compliance needs.

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process ensures security-first design, gas optimization, and audit readiness from day one.

  • Custom Business Logic: Implement complex workflows for DeFi, NFTs, DAOs, or enterprise use cases.
  • Security by Design: Built with Solidity 0.8+, OpenZeppelin libraries, and formal verification patterns.
  • Production Focus: Includes comprehensive testing, deployment scripts, and documentation for your team.

We deliver a fully functional, auditable codebase in 2-4 weeks for most MVPs, accelerating your path to mainnet launch.

Our engineers specialize in token standards (ERC-20, 721, 1155), DeFi primitives (AMMs, lending/borrowing), and cross-chain interoperability, ensuring your contracts are both powerful and future-proof.

BUILT FOR PRODUCTION

Core Technical Capabilities

Our EVM Mobile KYC integration is engineered for security, compliance, and seamless user onboarding. We deliver production-ready SDKs and infrastructure that scale with your user base.

01

On-Chain Identity Verification

Implement secure, non-custodial KYC flows that verify user identity and mint Soulbound Tokens (SBTs) or Verifiable Credentials directly on-chain. Enables compliant access to DeFi, gaming, and token-gated experiences.
