Node Operator Rewards
Withdrawing Consensus Layer Rewards
Node Operators receive rewards in the same way as any other validator on Ethereum. However, while Execution Layer rewards are earned normally and sent to the fee recipient address configured in the Beacon Node client, Consensus Layer rewards flow through the EigenLayer contracts and normally incur a delay.
To make the rewards withdrawal process fast and gas-efficient, Puffer has created a way for withdrawing rewards on Base L2. It requires a minimal amount of gas to withdraw rewards, and it allows validators to receive their rewards as quickly as possible and as often as they need. Node Operator Consensus Layer rewards are automatically bridged to Base L2 using Everclear, which validators can withdraw in the form of pufETH.
To withdraw rewards, Node Operators need to sign a transaction on Base by following these steps on the Puffer Dashboard:
- Click the "Claim" button
- Switch your wallet's network to Base. This step is necessary as the claiming process occurs on Base, and you'll need to sign a transaction there. Ensure you have sufficient ETH for gas.
- Click the "Claim" button again
- Review the transaction details carefully, then sign it using your wallet.
- Wait for the transaction confirmation. Once confirmed, you'll receive your rewards on Base.
After claiming the rewards, Node Operators can either bridge them back to Ethereum L1 or utilize them on Base L2.
How Rewards Are Calculated
Rewards are distributed daily, with the exception of the first distribution, which includes all rewards accumulated since Puffer's mainnet launch.
For each daily interval, Puffer's Guardians perform the following steps:
- Compute individual rewards for each Node Operator (sum of all of their associated validators)
- Calculate the total rewards for the previous intervals
- Create and publish a Merkle tree of rewards, storing it on AWS S3
- Mint pufETH tokens and transfer them to the Base Layer 2 network
- Enforce a mandatory waiting period to revert in case of a security vulnerability
- Once the waiting period ends, Node Operators can claim their rewards through the L2RewardManager contract on Base using the Puffer Dashboard
Rewards Epochs and accounting
Current Rewards Epoch — this is the epoch up to which rewards have been calculated and posted to Base.
Next Rewards Epoch — this is the epoch up to which rewards will be calculated in the upcoming accounting event.
We execute accounting automatically every 24 hours, but this period of time can be changed in the future.
We only mint and send to Base the rewards that have been successfully withdrawn from your validator on the Beacon Chain.
How to check if the rewards calculation is correct
- Take the Current Rewards Epoch from the dashboard.
- Go to beaconcha.in (or any other similar website) and find all withdrawals that occurred with your validators BEFORE this epoch, STARTING from your last Puffer rewards claim.
- Sum up these withdrawals.
- This total represents your expected rewards in ETH, which will need to be converted using the exchange rate at the epoch from Step 1.
Changing Your Rewards Recipient Address
Node Operators who used a smart contract (such as a multisig wallet) to register their validators on Ethereum Mainnet MUST set a specific rewards claimer address on Base. This step is crucial; without it, they may be unable to claim their rewards on Base.
The reason for this requirement is that addresses on Ethereum Mainnet do not automatically correspond to the same addresses on Base. Therefore, to ensure you can access your rewards, you need to explicitly specify which address on Base should be authorized to claim them.
To change your rewards claimer address on Base, a Node Operator should follow these steps:
-
Navigate to your SAFE account
-
Select
New transaction
-
Select
Transaction Builder
-
Enter the L1RewardManager contract implementation address: 0xbf11b5a0d7adeb5c1f2f3dbb85169594aa90c467
-
Select
Use Implementation ABI
- Set the
ETH value
amount to a small number, e.g.,0.000042
, this is the relayer fee to pay the bridge who will broadcast the transaction to Base. - Set the
Contract Method Selector
tosetL2RewardClaimer
- Set the
bridge (address)
to Everclear's bridge address 0x8898B472C54c31894e3B9bb83cEA802a5d0e63C6 - Enter your new rewards claimer address that you control on Base
- Click
Add transaction
and then sign the generated SAFE transactionnoteIf the
To Address
field doesn't auto-populate, it should be set to the L1RewardManager proxy contract address: 0x157788cc028Ac6405bD406f2D1e0A8A22b3cf17b. - Wait for the transaction to be bridged from Ethereum Mainnet to Base Layer 2. This process typically takes between 3 to 6 hours, but may take longer if the relayer fee is insufficient.
- After the transaction is confirmed on Base, the Node Operator can now claim rewards using the specified rewards claimer address on Base.
Externally Owned Accounts (EOAs) do not need to perform this step. For EOAs, rewards will automatically be sent to the same Node Operators address that registered the validators on Ethereum Mainnet.
