CORE SERVICE
Smart Contract Development
Secure, audited smart contracts built to your exact specifications by expert Solidity engineers.
Reduce your time-to-market and technical risk with contracts built for real-world use.
- Custom Logic: Develop
ERC-20,ERC-721,ERC-1155, and bespoke protocols for DeFi, NFTs, DAOs, and more. - Security First: Every line undergoes static analysis and manual review against common vulnerabilities before external audit.
- Full Lifecycle: From initial design and development to deployment, verification, and ongoing upgrade management.

PROVEN FRAMEWORK
Our Implementation Methodology
Our structured, four-phase approach ensures your Decentralized Identity solution is delivered on time, secure by design, and ready for production. We move from concept to launch in weeks, not months.
01
Architecture & Design Sprint
We conduct a 2-day collaborative workshop to define your DID use case, select the optimal protocol (W3C DID, Verifiable Credentials, OIDC/SIOP), and architect a scalable, interoperable solution.
2 days
Workshop Duration
3+
Protocol Options
02
Secure Sandbox Deployment
We provision a fully isolated, production-like sandbox environment pre-configured with your chosen DID method (e.g., did:ethr, did:web), wallet SDKs, and a private testnet for rapid iteration.
< 48 hours
Environment Ready

Development & Integration
Our engineers build and integrate core components: issuer/verifier logic, credential schemas, and user wallet flows. We implement best practices for key management, revocation, and privacy (ZK proofs).

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts on EVM and Solana with formal verification and gas optimization. Our contracts are built for high-frequency DeFi, enterprise-grade NFTs, and institutional-grade security.
- Security-First Development: Code audits,
OpenZeppelinstandards, and fuzz testing to eliminate vulnerabilities before deployment. - Gas Optimization: Reduce transaction costs by up to 40% with efficient contract logic and storage patterns.
- Full Lifecycle Support: From ideation and
Hardhat/Foundrytesting to mainnet deployment and upgrade management viaTransparent Proxypatterns.
Deliver a secure, audited, and gas-optimized contract suite in 2-4 weeks, ready for production traffic.
PRACTICAL QUESTIONS FROM CTOs
DEDICATED DID SANDBOX IMPLEMENTATION FAQs
Get clear, specific answers to the most common questions from technical leaders evaluating a dedicated DID sandbox environment.
A standard deployment takes 2-4 weeks from kickoff to production-ready environment. This includes DID method configuration (W3C DID, Verifiable Credentials), integration of your chosen blockchain (Ethereum, Polygon, Solana), and the setup of issuer/verifier/holder demo flows. Complex requirements like custom credential schemas or multi-chain attestations can extend this timeline, which we scope and quote for upfront.
