Indexer Architecture

The CRYMBO Indexer is a scalable, event-driven data layer that listens to smart contract activity across all supported blockchains. It transforms raw event logs into structured, queryable compliance metadata.

🔧 Components​

1. Event Listeners​

  • Node-based microservices watching blockchain events
  • Parse logs from the CRYMBO Oracle contract (e.g. PIIRequested, PIIReceived, Validated)

2. Normalization Engine​

  • Converts logs into standard schema
  • Tags identity types, scores, tx sources, wallet roles

3. Multichain Pipeline​

  • Per-chain indexers aggregate and push data to a common API
  • Supports EVM chains via Web3.js/ethers.js, and non-EVM via adapters

4. Compliance Registry (DB)​

  • Stores structured records:
    • Transaction hash
    • Network
    • Wallet IDs (sender/receiver)
    • Encrypted payload hash
    • Validator score(s)
    • Timestamps + status

📤 Output​

All indexed data is exposed via a unified REST/GraphQL API and supports:

  • Compliance dashboards
  • Explorer overlays
  • Webhooks for tx status updates
  • AI field suggestion learning inputs
