go-polynym VS bip39

That's weird, could just be some weird bug with the scanning of the QR code. If you are using a hardware wallet like Ledger on your PC then I would make sure its disconnected when trying to use ElectrumSV with no hardware adapted. I'm not sure if electrum has handcash handle support, but I would probably try to put your handcash handle into the tool at https://polynym.io/ and then it will translate it into a new handcash legacy address. Then you can copy paste and send to the legacy address instead of dealing with the QR code thing and hopefully it avoids the bug. You might want to try with a very small amount first to make sure its working.

Is there a tool similar to https://polynym.io where I can derive my RUN bitcoin address associated with my relayx handle?

Yes any BSV wallet is accepted, can change handcash handles to BSV addresses using https://polynym.io/

A cool tool to use it https://polynym.io/ to convert handles to Bitcoin addresses. +/u/BitsTipper 7000 bits

Download the offline version of the BIP39 tool via https://github.com/iancoleman/bip39/releases/latest. Right click on bip39-standalone.html and save the file.

You could make this with a Raspberry Pi Zero and the stand-alone version of the Coleman Web page+javascript https://github.com/iancoleman/bip39/releases/latest/

Since what I just said may be confusing... here it is in practice with a link so you can try it for yourself using Ian Coleman's Mnemonic Code Converter:

With Christmas coming around and the bull market upon us, I thought it would be a good time to remind everyone one about the art of mnemonic memorization. The idea is you take a BIP39 seed, then make a poem, story, limerick, or song using the words to help you remember. If you gift bitcoin, you can include the writing with the seed-card you provide to help the recipient remember as well. If you want to play along, go to Ian's BIP39 page and generate a valid seed mnemonic then see if you can't create a blurb of text that includes all the words.

You can try Ian Coleman's tool at : https://iancoleman.io/bip39/

13) Go to https://iancoleman.io/bip39/. There you need to change "Coin" value of the dropdown to "ETH – Ethereum". After that you can paste Secret phrase associated with Key 1 to “BIP39 Mnemonic” section

As I learned how to build websites, I wanted to use my new skill to help the crypto community in any way I can. So, I made a wallet generator website. It's like iancoleman BIP39, but with a nicer and more user-friendly design inspired by Tornado Cash, a simple way to make wallets from files/images, and support for Monero!
