Great! Glad to hear all your funds are there!
So to transition to having a seed-phrase, you essentially need to create a new wallet and transfer your funds over to it. There are two different way you could do this. I will outline both methods here so that we have a resource we can link others to later. There are a few steps, but it is fairly simple process which is worth doing to have more backup options to protect your funds.
Before you begin, be sure you have your private keys backed up for any addresses that hold funds.
For both methods you will need to know the location of your wallet.dat file. Its location depends on your operating system. Its a good idea at this point to backup your old wallet.dat to a USB where you also have your private keys saved.
Mac: ~/Library/Application\ Support/komodo/PIRATE/
Windows: %appdata%\komodo\PIRATE\
Linux: ~/.komodo/PIRATE
This method you install the lite wallet, send funds from treasure chest to the lite wallet, then import that same seed-phrase back into treasure chest
1) Install the lite wallet - https://pirate.black/wallets/desktop-lite/
2) Launch lite wallet, it will ask if you want to create a seed-phrase, select yes
3) BACKUP the seed-phrase and private keys safely!
4) Once lite wallet has finished sync'ing, send all your funds from the Treasure Chest wallet to your new lite wallet address.
5) Close the treasure chest wallet
6) Rename wallet.dat file to wallet.dat.bak
7) restart Treasure chest wallet.
8) when it restarts, it will ask if you want to restore a seed-phrase, select yes and enter the seed-phrase from the lite wallet.
At this point the Treasure Chest will need to rescan the blockchain which will take some time. Once it is done, you will see your balance in the new address. From hear on, every new address you create will be restorable with that seed-phrase
This method you backup your Treasure Chest wallet, create a new wallet, then import your old address into the new wallet.
1) In Treasure Chest, send all your funds to a single address in the wallet.
2) Once you verify all your funds are in a single address, backup the spending key
3) stop the wallet
4) Rename wallet.dat file to wallet.dat.bak
5) restart Treasure chest wallet.
6) when it restarts, it will ask if you want to create a seed-phrase, select yes
7) BACKUP the seed-phrase
8) Once wallet has scanned, go to the receive tab and add a label to the address in there so you remember it is "new address"
9) go to file -> import spending key, and paste in the spending key from the old wallet
10) Treasure chest will rescan teh block chain which will take some time
11) once rescan is complete you will see your old address with funds. Add a label to this address so you remember "old address - DO NOT USE"
12) send funds from your old address to the new address
At this point, all new address created will be restorable by the seed-phrase. Please keep in mind that any imported addresses, such as your old address, will not be restored by the seed phrase, only new addresses created in the wallet since the seed existed.
