Web based encoding/decoding electrum's base43 format

Base 43

Try it live at electrum43.org

The Electrum bitcoin wallet uses a custom base 43 encoding on data before it is displayed as a QR code. See the "base_encode" function here:

https://github.com/spesmilo/electrum/blob/master/lib/bitcoin.py

If you used a QR reader to transfer data from electrum off of a machine, you need to be able to transform that into a hex string before bitcoin will know what to do with it. This project offers a webpage and a js library that will decode the Electrum base 43 format.

For example, if the QR code you read was a transaction that you signed on an offline airgapped machine, after using this project to decode it you could use blockchain.info to decode the hex data or broadcast the transaction

Looking for a way to encode

the tagline says this does but cannot see how

Need to be able to round-trip deterministically

without coding

please

Bitcoind can not decode the hex

Thanks for the great tool. Unfortunately bitcoind is not able to decode the psbt. Any ideas why?

Here is the base43:

And even when I remove the electrum specific prefixes so that it is bitcoin core compatible hex to:

Bitcoin Core still can not decode it.
