Which one should you pick?
Pick Variational if
You want one cross-margined account for crypto, equities, commodities and forex with no visible trading fee.
A zero-fee venue built on RFQ rather than an order book: the platform earns the spread it quotes, so your real cost is the price you accept, not a line on a fee schedule.

Pick Extended if
Fee level is your deciding criterion and you want crypto and RWA markets on the same account.
The cheapest taker fee in the series at 0.025%, on a venue built by an ex-Revolut team that settles entirely on Starknet. Deposits are accepted from six EVM chains in USDC, ETH, USDT or wBTC, which removes the usual bridging detour.
