Three signature flags — NONE, SINGLE, ANYONECANPAY — are refused by the Dogecoin wallet I use. Each lets a counterparty rewrite the amount or the recipient after signing, and the chain still accepts it. Which is why the approval window shows net balance change, destination and fee, not a connect button. A prompt with none of those three numbers is a blank cheque. Not financial advice. #Dogecoin $DOGE
