Decentralized Identity for Contract Signatories

Integrate W3C-compliant decentralized identity (DID) and verifiable credential protocols into your smart legal agreements. We deliver systems that automate compliance, establish legal capacity, and create court-admissible, non-repudiable signatures.

overview
FULL-STACK INFRASTRUCTURE

Custom Blockchain Development

End-to-end blockchain solutions from protocol design to production deployment.

We architect and build custom blockchain networks and Layer 2 solutions tailored to your specific transaction volume, privacy, and governance needs. Our team delivers production-ready mainnets, sidechains, and app-chains with sub-2-second finality and 99.9% uptime SLAs.

  • Protocol Design: Custom consensus (PoS, PoA), tokenomics, and governance models.
  • Core Development: Rust-based (Substrate) or Go-based (Cosmos SDK, Tendermint) chain development.
  • Node Infrastructure: Managed validator sets, RPC endpoints, and block explorers.
  • Cross-Chain: Secure bridges and interoperability with EVM, Cosmos IBC, and Polkadot XCM.

Go from concept to a live, secure testnet in under 8 weeks. We handle the complex infrastructure so you can focus on your application logic and user growth.

Frequently Asked Questions

Get clear answers on how we build secure, compliant, and user-friendly decentralized identity solutions for digital contracts.

A standard implementation takes 3-6 weeks from kickoff to production. This includes requirements analysis, smart contract development, integration with your existing systems, and user testing. Complex multi-chain deployments or custom compliance modules can extend this timeline, which we scope and quote for upfront.
