Introduction

Welcome to the Crymbo Oracle Developer Documentation. This guide is intended to help Virtual Asset Service Providers (VASPs), technical partners, and compliance teams integrate securely and efficiently with the Crymbo Oracle platform.

What is Crymbo Oracle?​

Crymbo Oracle is a blockchain-based data relay and compliance solution that facilitates secure, encrypted identity data exchange between VASPs, in line with global regulatory frameworks such as:

  • MiCA (Markets in Crypto-Assets)
  • FATF Travel Rule

It ensures that all sensitive Personally Identifiable Information (PII) remains off-chain and encrypted, while providing an on-chain mechanism to initiate, verify, and track identity data requests.

Key Features​

  • Travel Rule Compliance: Built-in identity request and response flow to meet global compliance standards.
  • Zero PII On-Chain: Data is encrypted and passed directly between sender and receiver.
  • Decentralized Validation: Uses smart contracts and off-chain validators to verify actions.
  • Reward and Score System: Ensures high-quality participation by incentivizing correct and timely actions.
  • VASP-Only Network: Participation is restricted to verified and approved VASPs through KYB.

High-Level Architecture​

Crymbo Oracle integrates smart contracts, off-chain oracles, and a REST API to connect the decentralized and traditional web2 worlds.
