There is a native stablecoin on the internet-computer now: the CYCLES.
The CYCLES are stable at 1-TRILLION-CYCLES = 1-XDR.
Mint yourself some CYCLES at the CYCLES-TRANSFER-STATION: https://cycles-transfer-station.com, look how it feels. Then trade your CYCLES back and forth at the CTS-CYCLES-MARKET.
