Lido said EarnUSD, its stablecoin-based yield vault, will adopt a revised fee model with lower fixed charges, greater flexibility and a closer link to vault performance. The assets under management fee will range up to 0.5%, down from 1%, while the performance fee will rise to as much as 20%, from 10%. Initial rates will be 0.2% and 15%, respectively. Lido said the lower management fee will reduce the cost of holding EarnUSD when yields are low, and all fees will be displayed in the vault user interface.
