For me, on the iOS wallet the transactions appear after like 5 confirmations on the blockchain, they show up late but they DO show up. Maybe they showed up for your friend by now too?

How to see old addresses?

It works with any wallet that uses BIP39 seeds, and BIP32 derivation.

Mycelium uses "m/44'/0'/x'/y" as its BIP32 derivation path, where x is the account number (starting for 0 for account 1, 1 for account 2, etc.) and y is 0 for receiving addresses and 1 for change addresses.

Other wallets use different strings.

You can use the BIP32 tab at https://dcpos.github.io/bip39/ to enter any BIP32 derivation path you like. If you put m/44'/0'/0'/0 in there, then you'll see the Mycelium receiving addresses for account 0 (what Mycelium calls "account 1"). Apparently hive wallet uses "m/0'/0", and other wallets presumably use their own version. You can play about with the BIP32 derivation path field until you see your receiving address being generated.

I don't know any easy way of generating the keys from an xpriv - it would be nice if https://dcpos.github.io/bip39/ allowed us to edit the xprv field ourselves. I'll look into making that change.

Try this:

  https://dooglus.github.io/bip39/

I made the xprv field editable. I can't promise it works right, and the error handling isn't good at all. Click 'generate' then edit the xprv, and it won't tell you the value is invalid, it will just say "calculating" forever. But paste in a valid xprv code and it seems to work.

Edit: I made a pull request in the dcpos repository for this change to be merged into his site too: https://github.com/dcpos/bip39/pull/16

You could check that the addresses the webpage shows match the receiving addresses shown in your wallet app. That way you don't need to risk any funds.

I guess if the bits don't arrive in your wallet you can always just import the corresponding private key into bitcoin-core or some such to retrieve those bits.

Oh, well the list is infinite... You can keep generating addresses forever.

The way it works is that your wallet generates the addresses in order, and looks them up one at a time on the blockchain. When it finds N in a row that have never been used, it stops looking. N is probably 5 or 10 or some small number like that.

So if you funded the 100th address, your wallet won't have bothered looking that far ahead.

I made a change to https://dooglus.github.io/bip39/ so it will let you know if the xprv key you enter is invalid, rather than just saying "Calculating" forever.

I know work has been done on this since the above, but I still would like a currency option "none". That way I could cycle through USD, EUR, "none", depending on the situation. I realise I could go in the settings and remove the ticks, but it is rather tedious.

Sounds interesting, care to share some more information?

Have you selected EUR as a currency in "Settings" for "Local currency"?
