Module 9: DeFi Deep Dive

Staking and Liquid Staking

Chapter 8 of 14 · about 5 minutes

8.1 Earning from securing the network

Node held ETH long-term and had heard that staking could earn a few percent a year. "Is that real yield, or another inflation trick like Module 5, Chapter 3?"

"Partly both, and it depends on the network," said Hash. "On Ethereum, staking rewards come from new issuance plus transaction fees and MEV. It's payment for a real job: securing the network. But how you stake changes your risks dramatically."

8.2 What staking is

On proof of stake networks (Module 1, Chapter 4), validators lock up, or stake, the network's coin as collateral to propose and confirm blocks. In return, they earn rewards. If they misbehave, part of their stake can be destroyed, which is called slashing (Module 3, Chapter 5).

On Ethereum, running a validator requires 32 ETH. Since an upgrade in April 2023, stakers can withdraw their stake, subject to a queue (Module 6, Chapter 7).

8.3 Where staking rewards come from

SourceExplanation
New issuanceETH created by the protocol to reward validators
Priority feesTips paid by users to have transactions included (Module 3, Chapter 2)
MEVValue captured from transaction ordering, shared with validators (Module 3, Chapter 11)

Staking yield on Ethereum has typically been a few percent a year, varying with network activity and how much ETH is staked overall. The more ETH that's staked, the lower the yield per staker, because rewards are shared among more participants.

Remember the lesson from Module 5, Chapter 3: compare staking yield with network inflation. Part of the reward offsets dilution that non-stakers experience. Part, from fees and MEV, is real income from network usage.

8.4 Ways to stake

MethodHow it worksYou control keys?Main risks
Solo stakingRun your own validator with 32 ETHYesTechnical mistakes, downtime penalties, slashing
Staking servicesA provider runs the validator; you keep withdrawal control in some designsPartlyProvider performance and honesty
Liquid stakingDeposit any amount into a protocol, receive a liquid staking tokenThrough smart contractsSmart contract, operator, depeg, governance
Exchange stakingThe exchange stakes on your behalfNoCustodial risk (Module 1, Chapter 7)
Pooled protocols with decentralised operatorsMany independent operators run validatorsThrough smart contractsSmart contract and coordination risks

8.5 Liquid staking tokens

Staked ETH used to be locked and unusable. Liquid staking solves this. You deposit ETH into a liquid staking protocol, which stakes it through a set of node operators, and you receive a liquid staking token (LST) representing your staked ETH plus rewards.

The LST can be traded, used as collateral in lending (Chapter 5), or provided as liquidity (Chapter 3), while your ETH keeps earning staking rewards. This is composability at work (Chapter 1).

There are two main LST designs:

DesignHow rewards show upExample
RebasingYour token balance increases each day1.000 tokens become 1.0001, then 1.0002, and so on
Value-accruingYour balance stays the same; each token becomes worth more ETH1 token = 1.000 ETH, later 1 token = 1.05 ETH

A value-accruing example. Mint deposits 10 ETH when the exchange rate is 1 LST = 1.00 ETH and receives 10 LST. After about two years of rewards, the rate is 1 LST = 1.06 ETH. Mint's 10 LST are now redeemable for about 10.6 ETH.

Many DeFi protocols prefer value-accruing designs, because changing balances can complicate smart contracts.

8.6 The LST discount

An LST is meant to be worth its underlying staked ETH. But on secondary markets, like DEX pools, it can trade at a discount.

What happened in 2022. Before Ethereum allowed withdrawals, staked ETH couldn't be redeemed. When markets crashed in mid-2022, some large holders, including troubled crypto lenders, needed to sell their LSTs to raise cash. With no redemption available, the main LST traded at a discount of around 5% to 6% to ETH for a time. Investors who had borrowed ETH against LSTs (Chapter 11) faced liquidation pressure.

Since withdrawals became available in 2023, arbitrageurs can buy discounted LSTs and redeem them for ETH, which helps keep prices close. But redemption takes time because of the exit queue, so discounts can still appear during stress. The queue can grow long: in September 2025, a wave of validator exits pushed the wait above 40 days.

RiskEffect
Secondary market discountYou may receive less ETH if you sell rather than redeem
Exit queueRedemption may take days or longer during heavy demand
SlashingOperator mistakes can reduce the underlying ETH
Smart contractBugs in the LST protocol
GovernanceDecisions about operators, fees, and upgrades
ConcentrationOne large LST controlling a big share of all staked ETH could be a risk to Ethereum itself (Module 3, Chapter 13)

8.7 Fees

Liquid staking protocols and services take a fee, typically a percentage of staking rewards, such as 10%. If the base staking yield is 3%, a 10% fee leaves stakers about 2.7%.

8.8 Choosing a staking method

"So how should I stake?" asked Node.

"Match the method to your priorities," said Hash.

If you prioritiseConsider
Maximum control and decentralisationSolo staking, if you have the skills and 32 ETH
Simplicity and small amountsLiquid staking or reputable staking services
Using staked ETH in DeFiLiquid staking tokens
Avoiding smart contract riskSolo staking or reputable custodial services, accepting custodial risk
Supporting network decentralisationSmaller or more decentralised staking providers

8.9 Try it yourself

Find the current Ethereum staking yield from a staking dashboard, and the share of staked ETH held by the largest liquid staking protocols. Then pick one LST and check: is it rebasing or value-accruing? What is its current exchange rate to ETH? What fee does the protocol charge? What's its price on a major DEX compared with its redemption value?

Key takeaways from this chapter

  1. Staking locks coins to secure proof of stake networks, earning rewards and risking slashing.
  2. Ethereum staking rewards come from issuance, priority fees, and MEV.
  3. Staking methods range from solo staking to services, liquid staking, and exchange staking, each with different risks.
  4. Liquid staking tokens represent staked assets and can be used in DeFi while earning rewards.
  5. LSTs can be rebasing or value-accruing.
  6. LSTs can trade at discounts during stress, as in 2022; withdrawals help but exit queues remain.
  7. Consider fees, slashing, smart contract, governance, and concentration risks when choosing.
