Mercurial finance is committed to creating a more innovative stable currency exchange protocol. Compared with the traditional AMM stable currency exchange protocol, mercurial introduces a flexible transaction fee and liquidity fund allocation mechanism, that is, mercurial finance will not adopt a constant transaction fee rate, but the user's transaction fee will be adjusted with the system according to different transaction depths and transaction states, At the same time, mercurial will make immediate adjustments to the asset liquidity of the trading pool to create more revenue for LPS (liquidity provider) while meeting the transaction depth. Therefore, LPS (liquidity providers) of mercurial finance will no longer face the choice of obtaining more transaction fees or mining liquidity on other platforms. Mercurial aims to provide one-stop revenue optimization services for all LPS.
