Kalda
One wallet for all your crypto.
Kalda is a wallet you look after yourself. Hold, send, receive and swap coins from one app. One backup covers them all.
What is Kalda?
A crypto wallet on your phone. No bank or company holds your money. Nobody at Kalda can see it, freeze it or take it.
You hold the keys
Your wallet lives on your phone, locked by your fingerprint, face or PIN. 12 secret words back it all up.
Many coins, one app
Bitcoin, Ethereum, XRP, Zcash, Solana, stablecoins and more. See every coin →
Swap without an exchange
Trade one coin for another right in the app. No account to open. It goes from your wallet to your wallet.
Pay people, not addresses
Save friends as contacts. Then pay them with a tap, without typing long codes.
Private by default
Kalda pays the private way when it can. Send secret messages to contacts, too.
Made for how you use it
Pick an account type: Personal, Business, Investment, Trading or Developer. Compare them →
Every coin, connected
Kalda swaps through several exchanges at once, so almost any coin can become almost any other. Each line is a pair you can swap in one step. Its colour shows who does it.
- NEAR Intents
- THORChain
- Relay
- Uniswap
- Bridges
The cheapest road, found for you
Kalda checks every road, through up to three other coins. It gets a price for each and takes the one that leaves you the most. You confirm once; Kalda does every step.
The 36 roads Kalda weighs to swap Stellar for Bitcoin. One of them is lit.

Never share your 12 words
Anyone with them can take everything. Kalda will never ask for them. Neither will anyone honest.
Keep a paper backup
If your phone is lost or broken, your words bring your money back on a new phone. Without them, nobody can.

Questions
Does Kalda hold my money?
No. Your coins live on public blockchains. Only your phone holds the keys to them. Kalda can't see, move or freeze your money.
What if I lose my phone?
Install Kalda on a new phone and choose “I already have a recovery phrase”. Type your 12 words and your wallet comes back.
What if I lose my 12 words?
While you still have your phone, you can see them again under Profile → Backup & security. Write them down right away. If you lose both the words and the phone, nobody can get the money back.
Does it cost anything?
The app is free. Each payment has a small network fee, which goes to the network. Swaps also have fees. You always see them before you confirm.
Can I use my words in other wallets?
Yes, usually. Kalda uses the same open standard as most wallets, so your words aren't locked to Kalda.
