Decentralized Identity Verification for Payments

We build secure, compliant DID systems that replace manual KYC checks, reduce fraud by up to 80%, and enable instant, reusable customer verification for payment processors and fintechs.

overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your decentralized application.

We architect and deploy audited, gas-optimized smart contracts on EVM-compatible chains like Ethereum, Polygon, and Arbitrum. Our development process ensures your core logic is secure, efficient, and upgradeable from day one.

  • Security-First Development: Built with Solidity 0.8+ and OpenZeppelin libraries, following industry-standard patterns.
  • Full Audit Readiness: Contracts are structured for seamless review by top firms like CertiK or Quantstamp.
  • Gas Optimization: We reduce transaction costs by 20-40% through efficient coding and storage patterns.

We deliver a complete, deployable contract suite in 2-4 weeks, including documentation and a testnet deployment.

Our service covers the full lifecycle:

  • Token Standards: Custom ERC-20, ERC-721, and ERC-1155 implementations.
  • DeFi Primitives: Staking pools, liquidity vaults, automated market makers (AMMs).
  • Governance Systems: DAO frameworks with voting and treasury management.
  • Upgradeability: Proxy patterns (TransparentProxy, UUPS) for future-proofing.

Business Outcomes for Payment Providers

Integrating decentralized identity verification directly translates to measurable improvements in compliance, security, and user experience. Here are the concrete outcomes our clients achieve.

01

Eliminate Synthetic Identity Fraud

Our on-chain credential verification stops fraudulent account creation at the source by cryptographically validating user-provided data against trusted issuers, preventing the primary vector for payment fraud.
