🌉(Legacy) XY Bridge Fee Information

How is the bridge fee calculated?

Users are able to roughly estimate the cost of a transaction depending on the formulae given below as reference.

• A small portion of fees is taken as a basic commission. Note that one can imagine the feeRate in the formula below as a constant, or a percentage figure by which any transaction amount (trading volume) should multiply, usually determined by XY DAO.

$$BridgeFee = Amount *feeRate$$

• There are lower bound and upper bound in the Fee Structure to ensure that XY Finance can afford gas fees and will not impose any surcharges upon users.

$$\begin{equation} \left\{ \begin{array}{lr} BridgeFee=minimumFee, & minimumFee > BridgeFee \\ BridgeFee=Amount \cdot feeRate, & minFee < BridgeFee < maximumFee\\ BridgeFee=maximumFee, & BridgeFee > maximumFee \\ \end{array} \right. \end{equation}\notag$$

If the trading volume multiplied by feeRate is less than the minimumFee, then XY Finance will still charge the minimumFee as a basic commission.

If the trading volume multiplied by feeRate is more than the maximumFee, then XY Finance will only charge the maximumFee as a basic commission.

feeRate, minimumFee & maximumFee are determined by XYDAO.
