Will the server restart address information be lost?

[tzdadada]

Hello, may I ask, after my X-CASH Linux node generates an address, because the server restarts, I have no time to exit the node, will this part of the address be lost?

I generated some addresses before, but now using the "address all" command of "xcash-wallet-cl" on the node, I have not seen that the addresses have been generated before, and some transactions are also lost with the address. Any way to recover?

Hi @tzdadada

I am pretty sure the funds would be recoverable. You are talking about creating a sub address correct (the address format starts with an 8)

These are computed from your view key, meaning as long as you have the mnemonic seed of the "XCA" wallet you should never "lose" any of the sub-address wallets, as they are reconstructed at import of the mnemonic seed.

However I am wondering if either

1 The wallet cache got corrupted

2 You have hit a limit in the wallet for sub address look aheads

do you have any estimate of how many sub addresses you might have in that wallet. I ask because if you generate 200 sub addresses, and then generate the 201th sub address, if the first 200 have a balance of 0 but the 201 has a balance of > 0, it wont show in the wallet due to a limitation.

Also are these addresses under one account, or multiple accounts. I would assume 1 account unless you know they are not under one account.

My suggestion to fix both of these at the same time, if its the problem is to set the sub address lookahead to a higher number to see if that works, followed by a rescan of the blockchain

Note it will take longer the higher the number you set, but will only take longer the first time as the cache builds

so I would try the following for the sub address look ahead in order to see if it resolves the problem. You should probably try this out on your home computer if you can instead of the server, since this command takes a while on a less powerful computer.

Login to the wallet using the xcash-wallet-cli, then run this command set subaddress-lookahead 1:20000

Then rescan the blockchain rescan_bc

If this did not work try this instead

Login to the wallet using the xcash-wallet-cli, then run this command (note this will take a lot longer) set subaddress-lookahead 100:50000

Then rescan the blockchain rescan_bc

and let me know if it shows all of the sub addresses and your balance.

here is the link to our documentation for the CLI wallet as well https://docs.xcash.foundation/documentation/xcash-wallet-cli

I tried using the "set subaddress-lookahead 100: 50000", "rescan_bc" command, and it worked! My balance is displayed normally

details as following:

[wallet XCA1SM]: set subaddress-lookahead 100:50000
Wallet password: 
[wallet XCA1SM]: rescan_bc
Warning: this will lose any information which can not be recovered from the blockchain.
This includes destination addresses, tx secret keys, tx notes, etc
Rescan anyway ? (Y/Yes/N/No): y
