TrustDID is an open-source ecosystem focused on building decentralized identity, credential verification, and reputation infrastructure using the Stellar network and Soroban smart contracts.

Our mission is to create transparent, verifiable, and user-owned digital credential systems that can power education, employment verification, open-source reputation, DAO contribution tracking, and broader digital identity use cases.

OpenCred is the primary TrustDID platform for decentralized credential issuance and verification.

It enables organizations such as:

• Universities
• Bootcamps
• Employers
• DAOs
• Open-source communities
• Training platforms

To issue verifiable credentials that are:

• Tamper-resistant
• Publicly verifiable
• Decentralized
• User-owned

Credentials are stored on IPFS while verification data is anchored on the Stellar blockchain through Soroban smart contracts.

Backend infrastructure for credential issuance and verification.

• Credential issuance workflows
• Verification APIs
• PostgreSQL persistence
• IPFS integration
• Stellar blockchain integration
• Authentication and authorization
• Contributor-friendly backend architecture

• NestJS
• TypeScript
• PostgreSQL
• TypeORM
• Swagger
• IPFS
• Stellar SDK

Soroban smart contracts powering credential authenticity and verification on Stellar.

• Credential anchoring
• Credential verification
• Revocation tracking
• On-chain verification state
• Contract testing
• Deployment scripts

• Soroban
• Rust
• Stellar

Frontend platform for interacting with OpenCred.

• Credential dashboards
• Issuer portals
• Public verification pages
• Wallet authentication
• Credential sharing and viewing

• Next.js
• React
• TypeScript
• Freighter Wallet

TrustDID uses Stellar because it provides:

• Low-cost transactions
• Fast confirmations
• Scalability
• Accessibility for global users
• Strong open-source ecosystem support
• Soroban smart contract capabilities

These properties make Stellar an excellent foundation for decentralized identity and credential infrastructure.
