@milessuter @CashApp this is def exciting, if possible, would love to collab on this. currently thinking of interoperable payment QR for fiat and crypto wallets, which i believe is great to showcase crypto as payment rail

@felixzh_eth @CashApp Not yet but have some ideas.

We just shipped stablecoins on @CashApp. Everything runs from your existing USD balance - no separate wallet, no managing multiple chains, no extra setup, and importantly no fees. Send and receive USDC on SOL, ETH, POL, and ARB. The most seamless integration in the world imo.
