Enable a proposer

This guide will help you enable your Taiko node as a proposer.

Prerequisites​

You have already setup a node (see: Run a node)

Grimsvotn L2 :​

  • Must have a balance of ETH and TTKO on Sepolia L1 (see: Receive tokens).

Eldfell L3 :​

  • Must have a balance of ETH and TTKOe on Grimsvotn L2 (see: Receive tokens).

Steps​

Visit the TaikoL1 contract on block explorer​

First, you need to visit the TaikoL1 proxy contract:

  • If you are depositing TTKO, you can visit it here.
  • If you are depositing TTKOe, you can visit it here.

Click the write proxy tab​

Then, visit the "Write proxy" (Blockscout) or "Write as proxy" (Etherscan) tab.

Click the wallet connect button on the explorer.

Enter deposit amount​

Click the text field for depositTaikoToken and enter the amount of TTKO or TTKOe you would like to deposit followed by 8 zeroes.

info

Make sure to click the plus sign and click 10^8 decimals to add 8 zeroes, or add 8 zeroes manually.

For example if you want to deposit 81 TTKO/TTKOe, you would enter 8100000000.

Deposit your TTKO/TTKOe​

Click Write and confirm the transaction in your wallet.

Open .env file in simple-taiko-node​

Open the .env file in the simple-taiko-node directory.

Set environment variables to enable a proposer​

attention

Do not use a private key that is valuable to you. The private key will be stored in plain text in the .env file, and this is not secure. There is a real risk of losing your assets. You should only use a test account.

Set the following environment variables to enable your node as a proposer:

  • Set ENABLE_PROPOSER to true (replacing the default false with true).
  • Set L1_PROPOSER_PRIVATE_KEY to that of your wallet's private key; it will need some TTKO/TTKOe on Sepolia/Grimsvotn to propose blocks (if using MetaMask, follow these directions to retrieve the private key).
  • Set L2_SUGGESTED_FEE_RECIPIENT to the recipient of L2/L3 ETH rewards.

Verify proposer logs​

You should see a log if you have proposed a block: 📝 Propose transactions succeeded.

If you are running a node in the background, you can view the logs with docker compose logs -f.
