Seamless conversion between fiat and digital assets
Power compliant crypto on-ramps and off-ramps without building payments infrastructure.
Users expect instant conversion.

Classic transfers are broken
Friction
Users scan QR codes or copy 42-character addresses and pick the chain, where one mistake can be irreversible.A wallet address is a destination which cannot be authenticated before an onchain transfer.
Imprecision
No control over which accounts send assets, and checks happen only after assets land.
AUTH by zerohash solves onchain transfers
