Fiat-Based "Transaction Processors"
It would be interesting to see a fiat service for broadcasting Ethereum transactions to the network. Right now, most fiat on-ramps come in two flavours:
- A centralized exchange (like Coinbase, FTX and Binance). Poor user experience, slow, questionable regulatory frameworks, lack of transparency, often turn out to be insolvent.
- A fiat-to-token on-ramp (like Ramp.xyz and more recently Stripe). Better user experience, but limited in functionality and progammability.
I think there should be a third category: fiat-based transaction processors. Say you are an app developer and wish for your user to initiate a complex transaction flow, e.g.
CrowdfundContract#deposit(), but it requires a transfer of 5 USDC to the contract to succeed
