Hackathon: Pyth Network × Input/Output (Cardano)

What this project does

IntegralPayments is a modular payment gateway that installs as a plugin on
Dolibarr, Odoo, and Tryton — three major open-source ERP/CRM platforms.
It integrates the Pyth Network Oracle on the Cardano blockchain to pull
real-time cryptocurrency price feeds at the moment of checkout, enabling
businesses to accept crypto payments natively within their ERP/CRM workflow.

Pyth integration

• Uses Pyth Core in Pull Update mode via the Hermes API
• Consumes price feeds: ADA/USD, BTC/USD, ETH/USD, USDC/USD
• An Aiken smart contract on Cardano validates the Pyth price proof
  submitted with each payment transaction
• Fiat invoice amounts are converted to crypto at the live Pyth price,
  with a configurable slippage tolerance (default: 0.5%)

Cardano smart contract

Written in Aiken, the validator:

1. Accepts the Pyth signed price update as a redeemer
2. Verifies the proof on-chain
3. Checks the paid lovelace amount matches the expected fiat value
4. Emits a confirmation datum consumed by the off-chain service
