# Pendle Asset Prices Hourly

> Track prices and exchange rates for Pendle assets

The `ethereum.yields.pendle_asset_prices_hourly` table provides hourly price and exchange rate data for all Pendle market tokens, including LP tokens, Principal Tokens (PT), Yield Tokens (YT), and Standardized Yield Tokens (SY).

This data is fetched directly from Pendle's on-chain oracle contracts.
Note that all not Pendle assets may have corresponding USD pricing.

## Exchange Rates

The table tracks multiple exchange rates for accurate price derivation:

1. **LP Token Rates**

   * `lp_to_asset_rate`: Conversion rate between LP tokens and underlying assets
   * `lp_price_usd`: USD value of LP tokens

2. **Principal Token Rates**

   * `pt_to_asset_rate`: PT to underlying asset conversion
   * `pt_to_sy_rate`: PT to standardized yield token conversion
   * `pt_price_usd`: USD value of principal tokens

3. **Yield Token Rates**

   * `yt_to_asset_rate`: YT to underlying asset conversion
   * `yt_price_usd`: USD value of yield tokens

4. **Standardized Yield Rates**
   * `sy_price_usd`: USD value of standardized yield tokens
