Practical overview

When it fits

Use Paymint's documentation when assessing its Bitcoin wallet controls or examining the source. Its stated deprecation and lack of maintenance are important considerations for anyone evaluating it as a wallet.

Who it is for

  • Bitcoin users who want to label or block individual UTXOs.
  • People who want to review transaction amounts and fees before sending.
  • Developers exploring or building the documented Flutter application from source.

Documented uses

  • Label, block or unblock UTXOs and export their data to CSV.
  • Restore UTXO labels and block status from a CSV file.
  • Preview a transaction's amount and fee in BTC, satoshis or fiat before sending.
  • Export transaction data and review transaction values in fiat.
  • Build and run the app using the repository's Flutter instructions.
