could you explain what you mean by

"Have you tried to recover your wallet from other derivation paths with electrum?"

EDIT: yes, tried, but I don't think the private key they provided is complete enough to work for that. The private key provided only pulls up one receiving address.

File->new/restore->input bitcoin addresses or private keys---> only one address

file-->new/restore-->standard wallet-->use a master key (private key provided is too short..."import" is greyed out)
file-->new/restore--->standard wallet--->"I already have a seed" --->import is greyed out also when entering the seed provided.


Thanks. I have contacted them on Reddit and Telegram also. I have gotten some responses but only from robots that assume I'm stupid like "did you restore the wallet from your seed words or create a new one?"

I tried to test out a service called Atomic Wallet that is supposedly a semi-warm wallet that allows you to swap between different cryptocurrencies: https://atomicwallet.io/. I started with version 1.3.6, and sent .1206 BTC to the address provided 13rBSyzbiv27ZVdNPhn61oP9Mn7jA3iJ96. The coins were successfully received and are still in that address. The coins also appeared in the Atomic wallet interface. Yesterday, I upgraded the wallet to the latest addition and restored the wallet from the seed phrase, and to my surprise, the BTC balance was 0. I checked the Bitcoin address, and it was different, this time: 12XbpJCdnznzCWeJM7aFaZY8U4RfojRbME (balance of 0); however, the private key is the same.

I tried restoring via the private key on the Electrum wallet, and it also directed me to address #2 with the 0 balance. Keep in mind, I backed up everything (public key, private key, seed phrase), and the coins were clearly in the Atomic Wallet prior to the update to version 1.3.7; now, I have no way to access them as it appears Atomic Wallet provided me a mismatched public and private key, or my private key somehow is linked to multiple addresses (not sure if that's even possible). I have tried contacting support, and they have been very unhelpful and almost robotic, and I've lost my funds due to their wallet screw up. I did NOT get phished so far as I can tell (the coins are still in the address they provided; nothing has changed).

I hope the whole history is in some of the logs saved by Atomic, but I'd like to warn the users here to never use Atomic Wallet. Also, I will leave this notice up until Atomic Wallet either fixes my issue or provides compensation for their screw up.
