ETH 2.0 - Validator

Last updated
Once you have generated your keys, the next step is to submit a deposit using the Launchpad.
There is currently a shortage of Goerli ETH (testnet ETH) and you may not be able to find the 32 Goerli ETH + fees needed to make a testnet deposit.
As a temporary workaround, the EthStaker community has created a Discord bot that will make a deposit to Prater on your behalf using data from your Metamask transaction.
The deposit process still uses the launchpad, but instead of confirming the transaction through Metamask, you copy the transaction data and submit it to the Discord bot.
This section of the guide has been updated to reflect those changes.
You already installed an Eth1 node, synced an Eth2 beacon node, and generated the key pairs, so click continue until you reach "Upload Deposit File".
Drag and drop your Deposit Data file onto the launchpad site
You'll notice warnings that you don't have enough GoETH and the continue button is faded. Not a problem since you won't actually be sending the 32 GoETH through the launchpad.
You can't click CONTINUE because you're GoETH balance is too low, so we need to edit a command in the HTML code which will allow us to proceed.
Right click on the CONTINUE button and select Inspect (Q)
Change disabled to enabled as shown in this link, then close the editor.
After that change, you should be able to click CONTINUE and advance to the next page.
Check in the upper right corner in Metamask to ensure you are sending to the correct address

The bot should respond with a confirmation, but it may take some time to complete the deposit on chain if there is congestion on the Goerli testnet.
The deposit_data-[timestamp].json file contains your validator"pubkey" which you can use to check the status of Eth1 and Eth2 deposits.
Once the deposit is confirmed, you'll enter the queue and be assigned an activation epoch.
DepositsCopy your keystore file from the USB to the HOME folder then run the following command:
Once the keystore is imported, you can delete the keystore from the HOME folder.
You should save an offline copy of the keystore on the USB, but you can always generate a new keystore file using the 24 word mnemonic if needed.
