Katana is an Ethereum layer 2 built only for lending and trading. It uses the same address format as Ethereum, so one paste covers your position.
Gas is paid in ETH. KAT is an ordinary token on the chain rather than the fee token, though some chain listings report it otherwise.
The thing worth understanding before you import is what happens to assets you bridge in. They do not sit still, and the token you receive is not quite the token you sent.
What you get out of the box
Choisissez votre méthode d'import.

- Go to Kryptos.io and sign up with your Google account.
- From the menu, click Integrations.
- Click Add Integration and search for Katana.
- Click the Katana icon, then choose Import using Address.
- Give the wallet a name, paste your address, and click Import Your Transactions.
Good to know
- Gas is paid in ETH, not KAT.
- Bridged assets arrive as vault tokens with a vb prefix. Holding one does not pay you anything; the yield goes to the network.
- Staked KAT has a 60-day cooldown, and leaving early costs a fee that starts at a quarter of your position.
Two ways to stake, two different tax shapes
Katana lets you stake KAT in two ways, and they are not interchangeable as far as your records are concerned.
The first locks your KAT into a position that cannot be transferred or sold. Rewards accrue and you claim them yourself, which produces a dated transaction each time. That is the tidy case: each claim is income on its date at that day's value, and that value becomes the cost of the tokens you received.
The second wraps the position into a token you can move around. That version compounds automatically, so rewards never reach you as separate receipts. Your balance stays still while each unit becomes worth more, and the whole gain surfaces when you sell or redeem.
A tool looking for reward transactions will find plenty on the first route and none at all on the second, and someone using the second could reasonably conclude they earned nothing all year.
Both routes share a 60-day cooldown on the way out, and leaving before it finishes forfeits part of your position. That forfeit starts at roughly a quarter and falls as the cooldown runs down. It is worth treating as a genuine loss rather than a transfer fee, because the tokens are gone. For how staking income is treated where you file, see the USA crypto tax guide or the UK crypto tax guide.

Bridging assets in
What arrives is a vault token representing what you sent. It is a wrapper rather than a yield-bearing receipt, so your balance will not grow while you hold it.
Choosing how to stake KAT
One route gives you a position you cannot transfer and rewards you claim yourself. The other gives you a transferable token that compounds on its own. They have different tax shapes.
Lending on Morpho
Morpho holds most of the value on this chain, so supplying and borrowing there is the main activity to reconcile.

Vault tokens do not pay you
A bridged vault token is not like a liquid staking token. The yield generated behind it goes to the network, not to you, so holding one produces no income and modelling it as a yield-bearing asset would overstate what you earned.
The two staking routes behave differently
Locking KAT gives a position you claim rewards from, and each claim is income on its date. Wrapping into the transferable version compounds automatically instead, so there are no claim events and the gain appears when you sell or redeem.
Leaving early costs real money
Unstaking runs a 60-day cooldown. Exiting immediately forfeits around a quarter of the position, falling as the cooldown runs down. That forfeit is a real loss, not a fee on a transfer.
Gas is an ETH disposal
Fees come out of ETH. Anything pricing your fees against KAT is using the wrong asset.
Lecture seule par conception.
- Kryptos only ever needs your public wallet address
- A public address is read-only. It can't move or spend anything
- We never ask for your recovery phrase or private key
- Remove a wallet whenever you like, and its data goes with it

Assets bridged into Katana arrive as vault tokens with a vb prefix. They represent what you sent and can be redeemed for it.
That is by design. The yield behind bridged assets funds the network rather than paying the holder.
There is a 60-day cooldown. You can leave sooner, but a portion is forfeited, starting at about a quarter and falling as the cooldown progresses.
