# CurrencyUnits

> The measurement units of a pool's two slots. Present only for a pool whose raw side amounts are not measured in its tokens' contract metadata (for example a native-currency slot); null for every other pool, whose raw amounts follow `token0Data.decimals` / `token1Data.decimals`. `Token.decimals` is always the contract's metadata.

    decimals0: Int!
