How exactly does the 1inch Fusion work on ETH swaps?

So I decided to stop using Uniswap because of their crazy 0.25% fees on major pairs like ETH/USDC. Decided to use 1inch instead.

I connect my wallet and some Fusion option comes up, it says 0 gas. I am thinking “wow, perfect”. So I do a swap because fees are low at 5-6 gwei.

I do the swap and it’s successful. I go and check my wallet and I was charged like $15 for the swap fee. I also noticed for a simple ETH/USDC swap, I had like 10 different hops. Went from USDC to USDT then WBTC then SOL then Some other coin and finally into ETH. It was a large transaction and very expensive.

Reading the docs on their website, it says it should be gas free but I am still charged gas. Anyone know what is going on here?

From your explanation it is evident that it works the bad way . How about the TON network, have you ever tried it?
