Kusama Claims

The Kusama network is Polkadot's experimental, community-focused R&D network. If you held the DOT indicator token at the time of the genesis block of Kusama, you are entitled to claim an equivalent amount of KSM on the Kusama network.

You can claim KSM by signing a message with the Ethereum account that holds your DOT indicator tokens. There is no deadline for claiming KSM.

Step 1. Create a Kusama accountโ€‹

You will need to generate a Kusama account to claim KSM. There are a few ways you can create one.

For most users, we recommend using the Polkadot{.js} browser extension since it will allow you to store your encrypted keystore locally.

In terms of hardware wallet support, you can use the Kusama Ledger application, or Polkadot Vault.

Another option you may consider using is the Subkey command-line utility, which will allow you to take extra steps to protect the security of your key.

There are a variety of other wallets that you can use; see the Polkadot Wiki Wallets page for more details. Many of these wallets support generating Kusama accounts as well.

Using Kusama Ledger applicationโ€‹

Please follow the instructions for installing the Kusama Ledger application and then proceed to step 2 below.

Using Polkadot{.js} extension (Chrome/Brave or Firefox)โ€‹

  1. Install the Polkadot{.js} extension from the Chrome store or Firefox store.
  2. Click on the settings button to change the network to "Kusama (canary)".
  3. Create a new account by clicking on "Create new account (root or derived)".
  4. Uncheck the option to create an account dervied from another seed.
  5. Copy the seed phrase and store it somewhere safe. Don't share the seed phrase with anyone, you can use it to access your account if you forget your password or want to import your account again.
  6. Enter a name for the account and type a strong password (at least 6 characters).
  7. Click on "Add the account with the generated seed".
  8. You can copy the account's address to the clipboard by clicking on its identicon.

Using Subkeyโ€‹


You can install Subkey with this one-line command:

cargo install --force --git subkey

Note that you will already have had to install the correct Rust version and dependencies. If you have not done so, or experience problems installing using that command, run the following commands first, and then re-try the previous command:

curl -sSf | sh

rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly
rustup update stable
cargo install --git

Alternatively, you can build Subkey from the source code.

  1. Follow the build instructions for Substrate.
  2. When building, only build Subkey by typing cargo build -p subkey.
  3. The executable is ./target/debug/subkey.


You can use Subkey on a computer that is not connected to the internet for added security.

The command subkey --network kusama generate will generate a new key pair. If you want to be more secure, use 24 words, subkey --network kusama generate --words 24.

$ subkey --network kusama generate
Secret phrase `lobster flock few equip connect boost excuse glass machine find wonder tattoo` is account:
Secret seed: 0x95b90eb1344e3aea40f4a6dc81622901a2ac39efb331c41db10c311bb9b46927
Public key (hex): 0xfe7fce341ff73e1db537daa4cc8c539997a8b0654b06cb81c47e4f067f55a65a
Address (SS58): JL1eTcbzuZP99FjeySkDrMygNREPdbhRyV7iD5AsV4fDRcg

The Address (SS58) field is what you should use to claim your KSM tokens. Never share your Secret phrase or Secret seed, as these can both control your funds.

NOTE: Previous versions of Subkey only generated Substrate addresses. If you do not want to generate a new seed, you can convert the Substrate address to a Kusama address by following this section.

See the Subkey documentation or enter subkey --help for more usage examples.

Using Polkadot-JS UIโ€‹

  1. Open up the Polkadot-JS UI and navigate to the top left corner of the navigation. This will open up a panel of network options to select from. Select on "Kusama", either from Parity or Web3 Foundation, then "Switch".

  2. Navigate to the Polkadot-JS UI Accounts Tab and click on the "Add account" button.

kusama add account

  1. Enter a name for your account and create a secure password. This password will be used to decrypt your account. The required text fields to complete are highlighted in pink.

kusama create account

  1. Ignore the advanced options unless you want to change the type of cryptography used for your keys (we recommend "Schnorrkel (sr25519)"). You will have to enter an Account Name and a password to protect your account. Be sure to select a secure and hard-to-guess password. Note that anything will be accepted as a password here. Please note: There are no checks to see if it is long enough or secure. You will need this password for any future interaction with or transaction from this account.

  2. Click "Save" and "Create and backup account".

kusama save backup

  1. Save your encrypted keystore locally. Ideally, you would also save it on an external hard drive or thumb drive or print it out and be able to re-enter it later. You should not store it in cloud storage, email it to yourself, etc. You can use this backup file to restore your account. The seed in the backup file is not readable unless it is decrypted with the password.

  2. The account now appears in your Accounts tab and is backed up to the keystore you just saved.

  3. Click on the DOT identicon to copy the address to the clipboard. kusama copy address

Using Polkawalletโ€‹

  1. Install Polkawallet. Click "Download" and select the link corresponding to the platform you are using. On Android, you may need to allow installing apps from external sources. On iOS, you may need to "trust" Polkawallet in the "General > Profiles & Device Management > Enterprise App" section before running the app.

  2. Once the app is open, copy the seed phrase and store it in a safe place. Don't share the seed phrase with anyone, you can use it to access your account if you forget your password or otherwise lose your keystore.

  1. Name your account and make a strong password, make sure to write it down in another place, then click "Save".

  2. You will be asked to confirm your seed phrase - this is to make sure you have copied it somewhere safe.

  3. Click on the pink QR Code symbol and select "Copy address" to copy your address to the clipboard.

  1. Get the Kusama address from the Substrate address.

Kusama from Substrate addressโ€‹

If you used one of the generation methods that gave you a generic Substrate address (begins with a 5), then you will need to take an extra step to turn this into the properly encoded Kusama address.

  1. Copy your Substrate generic address to the clipboard.
  2. Go to the Polkadot-JS UI.
  3. Go to the "Settings" tab and find the "address network prefix" configuration.
  4. Select "Substrate (development)" and click "Save and reload".
  5. Go to the "Address book" and click the "Add contact" button.
  6. Enter your address and give it a name like "My Address".
  7. Go back to the "Settings" tab and select the "Kusama (canary)" option in "address network prefix" and click "Save and reload".
  8. Go back to the "Address book" and find the account you just added (it will have the same name).
  9. The address is now formatted as a Kusama address.

Step 2. Get KSM tokensโ€‹

There are two methods to claim KSM.

DOT Holdersโ€‹

Those who participated in the Polkadot sales before 2020 and have been allocated DOT indicator tokens on Ethereum can claim a proportional amount of KSM on the Kusama network.

To do this, you must sign a message containing the address of your Kusama account. You can do this by using the Polkadot-JS UI Claims app. Ensure that you are connected to the Kusama network (displayed in the upper-left hand corner of the screen). If you are not, change the network to Kusama by clicking in the network change tab in the upper-left-hand corner..

Generate a Kusama addressโ€‹

If you haven't already done so, you will need to generate a Kusama address. See step 1 above for detailed instructions first.

Claiming your KSM with MyCryptoโ€‹

The Polkadot-JS Claims app helps you sign a message from MyCrypto. MyCrypto is good to use in case you have stored the key to the Ethereum account holding your DOT indicator tokens on a hardware device like a Ledger Nano S or a Trezor. It also supports raw private keys, mnemonics, and the Parity signer.

Downloading MyCrypto

It is much more secure to download and use the MyCrypto app locally. Please make sure to download the latest version for your operating system. You can always find the most up-to-date releases of the desktop app on their releases page.

Once you've downloaded MyCrypto and have it running locally (we recommend an air-gapped computer for maximum security), you can start by navigating to the Claims app on the Polkadot-JS UI. Select the account you would like to claim the KSM into and click the blue "Continue" button to proceed. Your screen should look something like this:

Claim Step 1

The hex-encoded string that follows the sentence: "Pay KSM to the Kusama account:" is the hex-encoded public key of your Kusama account, minus the 0x prefix. To verify that the public key is correct, you can use the Subkey tool to inspect your address.

The next step is to go to the MyCrypto application and click on "Sign & Verify Message" tab. This will prompt you to select a method for unlocking your wallet. After unlocking your wallet, you will copy and paste the outputted sentence into the input box.

Claim Step 2

When you click "Sign Message" you will get a JSON output like the below:


Copy and paste the JSON output of the signed message from MyCrypto into the input box on the Polkadot-JS UI and click "Confirm Claim."


At this point, you will see a success message if everything went right and your KSM will now be in the account that you claimed to. Congratulations you can now participate in aspects of the Kusama network such as governance and staking. During the soft launch period balance transfers will not be enabled.

Claim Step 4]

Verifying your Claimโ€‹

After you make an on-chain claim for KSM, your balance should be updated on Polkadot-JS Apps immediately.

Are you having trouble? Get in touch on the Polkadot Support page.

Third Party Claims Processesโ€‹

We do not recommend using a third-party app or process to perform your claim or acquire KSM.

Claiming using a third-party process can lead to the loss of your allocation; therefore, we cannot recommend using any third-party apps to do so. Manually specifying your transaction data, as specified in our claims process, is the only way to be certain you will receive your allocation.
