This runtime api allows people to query the size of the liquidity pools and quote prices for swaps.

Provided Methods

fn quote_price_tokens_for_exact_tokens( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, coin1: Coin, coin2: Coin, amount: SubstrateAmount, include_fee: bool, ) -> Result<Option<SubstrateAmount>, ApiError>

Provides a quote for Pallet::swap_tokens_for_exact_tokens.

Note that the price may have changed by the time the transaction is executed. (Use amount_in_max to control slippage.)

fn quote_price_exact_tokens_for_tokens( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, coin1: Coin, coin2: Coin, amount: SubstrateAmount, include_fee: bool, ) -> Result<Option<SubstrateAmount>, ApiError>

Provides a quote for Pallet::swap_exact_tokens_for_tokens.

Note that the price may have changed by the time the transaction is executed. (Use amount_out_min to control slippage.)

fn get_reserves( &self, __runtime_api_at_param__: <Block as BlockT>::Hash, coin1: Coin, coin2: Coin, ) -> Result<Option<(SubstrateAmount, SubstrateAmount)>, ApiError>

Returns the size of the liquidity pool for the given coin pair.
