bitpay/copay help finding address/privatekey

[dadach]

Hi, so I can use my mnemonic phrase to simulate generating of the adresses online. I can see firsf 5 addresses that had funds on them. I have obviously transferred all the funds out, and now I am gonna claim BTG.

Addresses 2-5 have BTG on them when I check. Address 1 does not. I did one transaction that sent out BTC from that first address, and the funds went to CHANGE address. The trouble is, I cannot find that address when I keep generating more addresses with mnemonic phrase. That private key contains 95% of BTG. Can anyone help me how to find out the CHANGE address generation process? I mean it has to be derived from the same mnemonic right?

Thanks!

The change addresses are generated from the seed yes. Have you tried to use it in Electrum? use listunspent() to get the addresses where you have funds and then export the private keys from it?

What tool are you using for generating your addresses online? Are you using Ian Coleman's BIP39 tool (https://iancoleman.io/bip39/)?

If so, it sounds like the Derivation Path you are using is only showing "External" (aka "receive" addresses)...
