Heya, I just noticed I had some extra quipu tokens... @MadFishCommunity

When performing a swap on Quipuswap, slippage is used to protect users from price fluctuations. Slippage is a configuration set in the platform's settings, and it determines the maximum amount of difference in the exchange rate that a user is willing to accept. If the difference between the current exchange rate and the rate at the time of the trade is more than the configured slippage, then the trade will fail. When using multiple pools in a swap, the slippage will be applied to each exchange in the route. For example, if you are swapping uUSD to TEZ via QUIPU with a slippage of 0.5%, then 0.25% slippage will be applied to each trade (uUSD to QUIPU and QUIPU to TEZ). This means that 99.75% of the output of the uUSD to QUIPU trade will be exchanged in the QUIPU to TEZ trade, leaving a small amount of the uUSD to QUIPU output (QUIPU tokens) in your wallet. Unfortunately, since the size of this leftover cannot be known in advance, it accumulates in your wallet over time.

The prices on the exchange can fluctuate and can change just before your transaction is applied. As a result the whole trade will fail. To prevent this, the trading slippage is used. You can find its configuration in your setting on the platform. If the slippage is 0.5%, it basically says that you are ready to get up to 0.5% smaller output than it should be according to the current prices(only if prices will be changed). Usually, the best exchange rates are achieved by trading via few pools. In this case the slippage is applied on every exchange in your route. If you have 2 exchanges in your route uUSD->QUIPU->TEZ and slippage of 0.5%, than 0.25% slippage will be applied on each trade and only 99.75% of the uUSD->QUIPU trade's output will be exchanged in QUIPU-TEZ. If the rates didn't change before your uUSD->QUIPU trade is executed, you will have extra 0.25% of the uUSD->QUIPU output(i.e. QUIPU tokens). Unfortunately, we can't know the size of this leftover in advance(before you sign transaction parameters) and this small amount is left on your wallet.

Will get you a reply shortly.
