One of the Nimiq’s core elements is being able to atomic swapping crypto and fiat. And yet today, DeFi lacks of any on-off ramp. You still need to move your coins into centralized exchanges for that.
Thorchain (Rune) is a cross-chain dex with a huge ambition: to be able to swap any crypto asset natively (and not just “tokens” on the same blockchain). It already swaps natively coins like Btc, Eth, Doge, BNB, Ltc and it is integrating Luna. But it still would need a coin with a direct access to fiat.
