overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications.

We architect and deploy production-ready smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles and proven patterns.

We deliver custom logic for tokens, DeFi protocols, NFTs, DAOs, and more, with a focus on gas efficiency and upgradability.

  • Full Lifecycle Development: From specification and Solidity/Rust coding to testing, deployment, and maintenance.
  • Security Audits: Integration of OpenZeppelin libraries and preparation for third-party audits.
  • Key Deliverables: ERC-20, ERC-721, custom DeFi logic, multi-signature wallets, and governance systems.

PROVEN FRAMEWORK

Our Delivery Methodology

We deliver production-ready decentralized identity systems through a structured, transparent process designed for enterprise security and rapid integration.

01

Architecture & Protocol Design

We design your identity federation architecture, selecting optimal standards (W3C DIDs, Verifiable Credentials) and protocols (OIDC4VC, SIOPv2) for your specific use case. This ensures interoperability, compliance, and future-proofing.

Frequently Asked Questions

Get clear answers on how we deliver secure, interoperable identity solutions for your Web3 applications.

Our process follows a structured 4-phase methodology: 1. Discovery & Design (1-2 weeks): We analyze your use case, define user flows, and architect the DID method, verifiable credentials, and federation model. 2. Core Development (3-5 weeks): We build the smart contracts (Solidity/Rust), issuer/verifier SDKs, and user wallet integrations. 3. Integration & Testing (2-3 weeks): We integrate with your application, conduct security audits, and perform interoperability testing with standards like W3C DIDs and Verifiable Credentials. 4. Deployment & Handoff (1 week): We deploy to mainnet/testnet, provide documentation, and conduct team training. Most projects are delivered in 7-11 weeks.
