    This standalone webapp is a browserification of the bitcoin transaction tool, if you don't know very well how to use this tool for some parts, please see the examples there

    This tool under an open source MIT license is funded by NLnet under the EU Horizon 2020 Next Generation internet Search and Discovery call

    Unless you know very well what you are doing never use this tool online and make sure you don't have dubious software installed

    Offline means: even if the tool is a standalone one inside browsers and does not send/query anything outside, it is still highly advised to disconnect from the network when you are using your private keys (unplug the network cable, disconnect from the wifi, etc), click the below button to check that you are offline and get further recommendations

    Am I offline?

    For any question, bug report or support please email contact peersm com or post an issue on github

    Note: this is a beta version, until we remove this note please make sure to save this page as wallet.html somewhere if you use the tool to generate addresses
