Swaps
An overview on what Swaps on Duality are
Swap provides the most basic mechanism for exchanging one denom for another. It is a core building block of Multihop Swaps and Taker limit order. The swap operation operates by trading a
TokenIn through the liquidity pools that are provided by LPs and outputs a specified TokenOutWhen performing a swap we iterate through liquidity from best to worst price (PoolLiquidity and taker Limit Orders.) As we iterate through each instance of TickLiqudity we fully exhaust it before moving to the next TickLiquidity instance. This iteration continues until one of the following conditions is met:
All available liquidity has been exhausted – Note: If there is no available liquidity for the given Pair and TokenIn at the beginning of the swap it will fail and return an
ErrInsufficientLiquidityerror. If swap is called through a IMMEDIATE_OR_CANCEL limit order it will still succeed if liquidity is exhausted and only a portion of the AmountIn has been used. In all other cases a partial fill of a swap will result in a failure.
The AmountIn has been hit (ie. the user has swapped through 100% of the supplied TokenIn MaxAmountOut has been set and the TokenOut amount is equal to MaxAmountOutIn cases where only a portion of the maxAmountIn is used only the used portion of
TokenIn will be debited from the user's account.Last modified 4mo ago
