I was dealing with the same frustration until I found a direct swap option. You can swap eth to sol in just a few steps without ever touching fiat. The process is simple: enter the amount you want to swap, provide your SOL wallet address, and send your ETH to the specified address. The rate locks in at the start so price fluctuations don't affect you. It works with any wallet and the swap completes within minutes. Much cleaner than the old off-ramp/on-ramp method and saves on double fees.
