ENTERPRISE-GRADE INFRASTRUCTURE
Core Capabilities of Our DID Registry Build
We deliver production-ready, secure, and scalable DID registries that integrate seamlessly into your existing systems, accelerating your Web3 identity initiatives.
02
Multi-Method & Multi-Chain Support
Future-proof your identity layer. We architect registries that support multiple DID methods (e.g., did:ethr, did:key, did:web) and can be deployed across EVM, Solana, or Cosmos-based chains based on your needs.
03
Gas-Optimized Smart Contracts
Minimize operational costs. Our DID registry contracts are built with Solidity 0.8+ and OpenZeppelin libraries, employing advanced patterns to reduce gas fees for DID creation and updates by up to 40%.

DID Registry Development: Key Questions
Answers to the most common questions CTOs and product leads ask when evaluating a DID registry build partner.
Standard DID registry deployment takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, integration with your application layer, and security audit review. Complex requirements like custom resolver logic or multi-chain support can extend this to 6-8 weeks. We provide a detailed project plan in week one.
