IMPORTANT: This claims process only applies to DOT (old) that were purchased in the form of DOT Allocation Indicators on Ethereum before June 30, 2020.

If you bought your DOT tokens more recently or from another source, this process does not apply to you. You do not need to claim. If you have any questions about DOT, please search this support page or contact us.

Before you start

1. Do you already have a Polkadot address? 

  • If you previously created an account in the Polkadot browser extension or a different wallet, you can skip the account creation process and scroll down to the Making a Claim section. Make sure you have Polkadot selected on the top left, like in the video shown at the bottom.

2. If you don't have a Polkadot address yet

If you don't already have a Polkadot address, you'll need to create one first. The Polkadot browser extension is recommended for most users. If this is the first time you are creating an account, please pay extra attention to this. During this process, you will be shown a mnemonic seed phrase. 

This mnemonic phrase is the most important detail of your Polkadot account. It is your master private key to your DOT. Whoever has those 12 words will be able to access your DOT. It is therefore important that nobody but you ever sees those 12 words and it is also important that you never lose them. Check out these steps on how to properly store them.

NOTE: Accounts created in the extension don't automatically export the account in a JSON file. You'll need to do this manually in order to restore using the JSON file and password.

Making a Claim

If you made a DOT purchase in one of the pre-launch sales, then you will need to claim your DOT tokens. For those who made a pre-genesis claim by sending a claim transaction to the Claims contract on Ethereum, you will still need to send a free attest transaction to agree to the terms and conditions of your allocation. In that case, see the wiki guide instead on How to Attest.

If you did not make a claim in the pre-genesis claims period, follow the below guide to claim your DOT tokens after genesis. There is no time limit for making your claim, so feel free to do this at any time.

NOTE: When you make a claim, you will also attest to the agreement that corresponds to your DOT allocation. The two actions, "claim" and "attest", are done in a single transaction.

What you will need

  • The Ethereum account that holds the DOT indicator tokens
  • The MyCrypto Wallet
  • A Polkadot account

You should already have your Ethereum account that holds the DOT indicator tokens from Polkadot's prior sales. You will need to have access to this account in order to make a signature.

MyCrypto is a versatile wallet that supports a variety of storage methods for your Ethereum account. Go to their downloads page and ensure that you download the latest version for your operating system. This is important because the latest version will always have the latest security patches.

IMPORTANT: It is much more secure to download and use the MyCrypto app locally, by using their desktop application.

You can then use the claims guide to claim DOT that were purchased in the form of DOT Allocation Indicators on Ethereum before June 30,2020. These steps are broken down in the remaining sections of this page.

Claiming your DOT with MyCrypto

The Polkadot-JS Claims app will help you to sign a message from the MyCrypto wallet. MyCrypto is a good choice if 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 Parity signer.

1. 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 Polkadot-JS Apps. Select the account you would like to claim the DOT into and click the blue "Continue" button to proceed. Your screen should look something like this:

2. Now you will need to provide the Ethereum address that is associated with the DOT indicator tokens that you will claim. Enter the Ethereum address into the box and click "Continue".

3. Next, your screens should look like the image below.

4. 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.

5. After unlocking your wallet, paste the message from Polkadot-JS into the "Message" box.

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

7. 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."

8. A green box will appear telling you the amount to claim with a "Claim" button to make the claim. Click on the "Claim" button and click "Submit (no signature)" to complete the claim.

If this claim succeeded, then you will see a success message and your DOT will be in the account that you claimed to.

Third-Party Claims Processes

We don't recommend using third-party apps or processes to perform your claim or acquire DOT. This can lead to a loss of your allocation. Manually specifying your transaction data, as specified in our claims process, is the only way to be certain you will receive your allocation.


If you have already made a pre-genesis claim but still need to attest, please follow these instructions instead.

Accessing your Account

You will be sending a free transaction from your Polkadot browser extension account on the Polkadot-JS Apps UI. Once the transaction is complete, the tokens will be available in your account. You will first need to grant access to the site via a pop-up from the extension.

Make the Attestation

After entering your account, you should see a red counter appear on the "Claim Tokens" tab on the left navigation drawer.

1. Click on the "Claim Tokens" tab and you will see a large notification at the top of the page that tells you an attestation needs to be signed.

The notification will display one or more Polkadot addresses that you have loaded in Polkadot-JS that you need to sign. Select a Polkadot account with a claim using the drop down selection. If you don't see a notification or don't see the selector, please double check that the account has been loaded into Polkadot-JS and that it has already claimed during the preclaim period. 

2. Click "Continue" and you will see a green box appear on the right.

3. Click on "I Agree" and then "Sign and Submit" to make your free attest transaction. When the transaction is included in the block, you will see a green success box appear in the upper right corner and the DOT will be in your account.
