Ok cool, thanks for your help! Is v3 the most widely accepted token version? I’m not familiar with the differences. I tried looking it up, but not sure where v3 and v4 tokens are defined.

Sorry for hassling, but I appreciate the help! I don't understand why I'm seeing this error: "Not enough funds available (1) for swap amountToSend: 1 + fee: 0 | length: 1" To me this means: 1 sat is available. 1 sat is intended to be sent. No fee. 1 proof of 1 sat to send. Yet 1 sat is not enough to send 1 sat? From this code: cashu-ts/blob/main/src/CashuWallet.ts

@npub1hee4...rsv6 alternatively you can use Macadamia on iOS which supports v4 (at least in TestFlight):
