Are there any docs about the ETH staking and how I set up my wallet etc.?
Yes — there is a user guide (opens in a new tab).
What is the minimum amount of ETH I can stake?
There's no minimum amount, you can stake any.
What is the change interval to increase my stake?
There's no change interval, you can stake any amount.
Is there a maximum amount I can stake?
No, you can stake at your discretion, unlimited. You should know that currently staking starts once 32 ETH are accumulated, so if your stake is > 32 ETH, it’ll be divided into chunks and the rule will apply to each of them.
When can I unstake?
Currently, unstaking is not available, as this functionality is not yet supported by Ethereum.
Unstaking will be enabled after in the Shanghai upgrade that will follow The Merge in 6-12 months.
Overall, it looks like Shanghai is going to happen April 12, 2023.
How long does it take to unstake my ETH?
Currently, there is no unbonding period, as there is no unstaking for ETH. This functionality is to be implemented by the Ethereum team in future updates.
How do I receive rewards?
aETHb is not actively supported anymore. We recommend you switch your aETHb for ankrETH (ex-aETHc) (opens in a new tab).
ankrETH (ex-aETHc) is a reward-bearing token, meaning its quantity stays the same from the moment of staking. Instead, it appreciates in value in relation to ETH, so the redemption price of 1 ankrETH will grow over time because of reward accumulation.
Mind that to pull out your rewards, you’ll need to sell ankrETH (ex-aETHc) on Ankr DeFi, as Ethereum hasn’t implemented the unstaking functionality yet. Overall, it looks like the unstaking functionality comes to Ethereum on April 12, 2023.
How soon after staking will I begin to receive rewards?
ankrETH (ex-aETHc) will increase in value only, daily. arnkETH rewards are built into the token. Effectively, your rewards accumulate daily as ankrETH grows in value to ETH.
Does Ankr charge for the service?
Ankr takes a 10% fee from the staking reward.
Is there any risk from staking, like slashing or any penalties?
The only risk for stakers is missing out on rewards during any time a validator they staked with is slashed. Slashing is a protocol-level penalty associated with a validator failure if it validates an invalid transaction or goes offline. The delegated staked ETH is not slashed — slashing impacts only the self-stake of the validator. Ankr only delegates to trusted and reputable validator nodes to avoid any validator that would act maliciously.
Is there any liquidity for my Liquid Staking tokens anywhere?
You can trade them in the listed liquidity pools on ANKR DeFi:
You can also use your Liquid Staking tokens to:
-
Add liquidity on DEXs (opens in a new tab) and earn from commissions taken when users swap tokens, using the liquidity pool you're a part of.
-
Yield farm (opens in a new tab) and earn additional rewards in the form of liquidity pool tokens and further farm them.
-
Put your tokens in a vault (opens in a new tab) and automatically earn additional rewards in the form of one of both assets from the pair.
Why do I get less ankrETH (ex-aETHc) for my 1 ETH?
ankrETH (ex-aETHc) only changes in value, which is why the amount of ankrETH you get when staking is calculated by the formula stake * exchange_ratio. The exchange ratio is calculated like this: totals_supply_of_ankreth / (total_staked_eth + total_rewards_for_staked_eth - total_unstaked_ankreth).
Can I use cold wallets for staking?
Yes, you can use Ledger Nano cold wallets through MetaMask. Visit the Ledger's guide on connecting Ledger through MetaMask (opens in a new tab).
