System Data Flows

The publisher fetches EUR/USD spot from Pyth, computes forward prices using interest rate parity, and publishes them onchain. The OracleModule applies safeguard checks before storing.For safeguard parameters and deviation thresholds, see Oracle Safeguards. For the forward pricing formula, see Oracle & Forward Pricing.

The keeper polls for matured and liquidatable positions, then processes them in batches. All settlement and liquidation functions are permissionless.For operational details, see Keeper Automation.

Trading fees and liquidation penalties are split between treasury and pool via FeeLib. Oracle fees go directly to the oracle fee receiver.For fee formulas and parameters, see Fee Structure. For LP share price impact, see Fee Distribution.

LPs deposit USDC into the ERC-4626 PoolVault. Shares are minted proportional to existing total assets, making fee accrual automatic.For vault mechanics and share price calculation, see Vault Mechanics and Share Price.

Contracts emit events that Graph Node processes via handler mappings. Entities are stored and queryable via GraphQL through the Gateway API.For subgraph schema and query examples, see Subgraph Overview and Query Examples.
