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.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts for your protocol or application.
We architect and deploy custom smart contracts that form the secure, immutable backbone of your Web3 product. Our development process is built on Solidity 0.8+ with OpenZeppelin security patterns and includes comprehensive unit testing for every function.
From token standards to complex DeFi logic, we deliver code you can trust to handle real value.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155contracts with minting, vesting, and governance modules. - DeFi & DEX: Automated Market Makers (AMMs), liquidity pools, staking, and yield farming mechanisms.
- Security First: Every contract undergoes manual review and automated analysis with tools like Slither and MythX before deployment.
- Full Lifecycle: We handle deployment, verification on block explorers, and provide detailed technical documentation for your team.

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.
