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 f 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∗fBridgeFee = Amount *f
  • 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.
If the trading volume multiplied by f is less than the minFee, then XY Finance will still charge the minFee as a basic commission.
If the trading volume multiplied by f is more than the maxFee, then XY Finance will only charge the maxFee as a basic commission.
f, minFee & maxFee are determined by XYDAO.
