Methodology

Important: All pricing is provided on a best-effort basis and is not guaranteed. Market prices may be manipulated, skewed, stale, or unavailable. Receipts are provided for informational purposes only and do not constitute financial advice.

All prices are measured at the block immediately before the transaction.

Market Price

WETH/USDC Price:

The median price from three designated WETH/USDC liquidity pools, cross-referenced against an oracle reference. Used directly for WETH/USDC transactions or as a reference when pricing other token pairs and gas cost.

All other prices may use up to three methods:

Direct-Pool Price:

The midpoint price from the deepest qualifying liquidity pool that trades the input and output tokens directly.

WETH-Derived Price:

The implied price linking the input and output tokens together through WETH. It is calculated from the midpoint price of the deepest qualifying token/WETH pool for each applicable token, cross-referenced against the WETH/USDC price method. For example, AAA/WETH and WETH/BBB can be combined to derive an AAA/BBB price. Used to corroborate a direct-pool price, or provide a fallback when no direct-pool price is available.

Oracle Reference:

An independent reference price calculated from external price feeds (Chainlink) for the input and output tokens. Used to corroborate liquidity-based prices within a tolerance of 50 bps, or 0.50%. Oracle reference is never used to calculate Market Price.

When at least 2/3 methods agree, prices are Verified. When only the direct-pool method or WETH-derived method are available, prices are Estimated. When neither, prices are Unavailable.

Per-Leg Price

The midpoint price from the leg’s executing liquidity pool. When unavailable, the deepest qualifying liquidity pool for the same token pair is used as a fallback. Market maker legs remain unpriced by nature.
