PROVEN FRAMEWORK
Our Delivery Methodology
We deliver production-ready decentralized identity systems through a structured, transparent process designed for technical founders and CTOs. Our methodology ensures security, interoperability, and rapid time-to-market.
01
Architecture & Specification
We define your DID method, credential schemas, and key management strategy. We deliver a technical specification document covering protocol selection (W3C DID, Verifiable Credentials), wallet integration, and compliance requirements.
1-2 weeks
Specification Phase

Technical Alignment
02
Smart Contract Development
Our engineers build and audit the core on-chain logic for DID registry, key rotation, and revocation. We use Solidity 0.8+ with OpenZeppelin libraries, implementing gas-optimized patterns for your target EVM chain (Ethereum, Polygon, Arbitrum).

Frequently Asked Questions
Get clear answers on our technical approach, security guarantees, and delivery process for implementing secure key binding for your identity solution.
A standard implementation for a DID method with key binding takes 3-5 weeks from kickoff to production deployment. This includes architecture design, smart contract development, SDK integration, and security audit. Complex multi-chain or custom revocation logic can extend this to 8 weeks. We provide a detailed project plan with weekly milestones.
