After Polkadot CC1 went online yesterday, I received a lot of small partners’ inquiries about how to map DOT. Today we will share one of the functions of Polkadot CC1: how to map DOT on polkadot.js.org/apps/#/claims!
Regardless of whether your DOT has been mapped before Polkadot CC1, you need to do the DOT mapping and claim through the following process!
You will claim the transaction by submitting an attest without transaction fees, which is used to agree to your terms and conditions of distribution. You must declare and claim before DOT can be used in your account.
Step 1: Create a DOT account
Open https://polkadot.js.org/apps/#/accounts , click Add account directly, save the JSON file and your private key. (Note: The DOT address starts with 1)
Step 2: Claim
If you did not claim before the genesis block, you can claim it any time after the genesis block. There is no time limit for claiming! When claiming, you will also make a statement about the required distribution terms. These two actions “claim” and “attest” are completed in one transaction!
You need to be ready now:
- Ethereum account address, private key / mnemonic holding DOT tokens
- Download the latest version of MyCrypto wallet: https://download.mycrypto.com/
1. Open polkadot.js.org/apps/#/claims, select the DOT account you just created or have, and click the Continue button.
2. Enter the address of the Ethereum account holding DOT tokens and click the Continue button.
3. The following picture is displayed. Part 1 is the DOT allocation terms, which can be read down; Part 2 is a string of character information automatically generated, including your DOT public key address and the DOT allocation terms information you need to declare “claim” and “attest” are done in one transaction. So you need to click on part 2 and the string of characters will be copied directly.
4. Open MyCrypto’s Sign & Verify Message to sign the message string just copied. First of all, you need to choose a way to unlock your Ethereum account holding DOT tokens. If your private key is stored in a cold wallet such as Ledger or Parity Signer, you can choose these two directly. If not, you can choose one of the following three methods (private key, Keystore file, mnemonic) to unlock.
5. After unlocking the wallet, paste the information you just found in Polkadot JS into the “Message” box and click Sign Message.
6. If your message is successfully signed, the JSON result in the red box below will appear. Next, you need to copy and paste it into the input box of Polkadot JS, and then click “Confirm Claim”.
7. A green box will appear showing the amount of DOT you want to claim. Click the “Claim” button and then click “Submit (no signature)” to complete the claim.
8. If the claim is successful, you will see a success message and the DOT will be displayed in your account.
Congratulations, you have now completed DOT mapping and claiming! You can now staking in Polkadot CC1 (probably not yet profitable) or when the Poalkdot network is converted to NPoS network to mortgage the verifier or as a nominee to maintain the network, and enjoy the corresponding benefits and rewards! After the Polkadot network finally removes the sudo module, after the referendum opens the transfer function, your DOT will be in circulation!
