Multi-asset margining allows traders to use different assets as collateral for derivatives trading. While in V2, the user can deposit only USDC as collateral, in V2.5, it will be possible to use other cryptocurrencies, for instance, SPIN, BTC, ETH, and REF. To use them as collateral, it is necessary to indicate the price of cryptocurrencies in USDC, in which case Flux Oracle will be used.
