investigating
Let me give you a more complete picture for the investigation.
Currently, I have Layerz Wallet installed on two phones:
First phone (Version 1.5.4): Displays the correct transaction history up until July. However, after that, there is a transaction 173c5f40c81f8058789590f63a875b5528407f18e78479a907d3d1ad94ec650e dated July 1 at 00:48:20 (GMT+4). I did not make this transaction, and it shows 220,142 satoshis being withdrawn from my balance.
Second phone (Version 1.6.0): Has no transaction history displayed at all.
When importing the seed phrase from Layerz Wallet into Arkade.Money and Chimera Wallet, both show the correct transaction history: prior to July, it matches the history from Layerz Wallet v1.5.4. However, in July, the unauthorized transaction 173c5f40c81f8058789590f63a875b5528407f18e78479a907d3d1ad94ec650e is missing. Instead, there is transaction b3db89ccb92379e6b5e4669e005047d7a8e6df971e4209d5fc42836e2e83faf4 dated July 4 at 13:03:14 (GMT+4), which I actually performed in Arkade.Money to withdraw the 220,142 satoshis.
Additionally, I would like to note that on July 2, I contacted Layerz Wallet support and opened ticket #497 regarding this issue, but the ticket remains unanswered to date.
