I guess this is why Farcaster drops their sign up fees and integrates a WC wallet. If there's a lot of trading happening via WC and they get a cut each time, it can provide more revenue than sign up fees.

The most boring vision of crypto, that "transaction fees" are the "killer business model." This is LinkedIn cringe

But isn't it true? This is how Uniswap, Aave, Pumpfun, Zora et al make money.

I agree that the second category where you just take a % on a swap is boring. But the first one, where your app is also a home to new asset creation is IMO interesting.
