Any update? I have the same issue. I was using instawallet many years ago and found out that on its address there are some satoshis I'd like to get back. The block explorer shows that the address was untouched. I don't have any keys or seed, just an old link to instawallet like this:
https://instawallet.org/w/some_long_code_here@ThatCookieMonster @Boussac @JeromeTash:
https://twitter.com/Bitcoinuser/status/1513525555982917636I think the only thing we need from the author of InstaWalllet is how to convert this "some_long_code" in the URL
https://instawallet.org/w/some_long_code to the private key of the destination BTC address. I suppose that this could be done quite easily, but the source code is needed.
DM me if there any updated, thanks.
The problem with people is they never come back with any update here. They just go quiet, so t's hard to know if their issues got resolved or not.
