Ideally that will accept GBP deposits to save me messing around with swapping in GBP to USDT and then wallet transfers.
This is the hard part.
Supposedly if you're not burdened with converting your money to stabelcoin you can use DEX to make a leveraged trade, something like hyperliquid, jupiter, and so on.
Since they are dex, their perpetual trading pairs are open to everyone.
