CredChain Product Documentation & User Guide

CredChain is a decentralized academic and professional credential verification platform built natively on the Stellar Soroban smart contract engine. It provides instant, tamper-proof, public verification of certificates without middlemen or centralized databases.

Key Value Propositions
Why CredChain replaces legacy centralized background checks and diploma mills.
Frictionless Public Verification

Scan the QR on a credential or open /verify/<id>. No wallet, no account, no subscription — the page reads straight from the ledger.

Sub-Cent Transaction Settlement

Built on Stellar Soroban, issuing a credential costs fractions of a cent and finalizes in ~5 seconds with sub-second RPC latency.

Self-Contained On-Chain Credentials

Holder name and title are encoded into the credential itself as a data URI, so verification reads the whole record from the ledger with no server to trust. Writes extend persistent-entry TTL to keep records live.

Decentralized Multi-Wallet Support

Supports Freighter, Albedo, and xBull via the Creit Tech Stellar Wallets Kit, with opt-in session persistence.
