Crypto staking explained

What is crypto staking?

Some blockchains are secured by “proof of stake” rather than by mining. Instead of spending electricity, participants lock up the network’s own coins as a security deposit. ethereum.org defines it for Ethereum: “Staking is the act of depositing ETH to activate a validator, a participant in Ethereum's consensus protocol.”

Validators propose and check new blocks. The network pays them rewards for doing that job properly and penalises them for failing at it. When people talk about “staking” their crypto, they mean either running a validator themselves or handing their coins to someone who does. Ethereum has used proof of stake since “The Merge” on 15 September 2022 — see what Ethereum is.

How does proof of stake work?

In short: the more you have locked up, the more you have to lose by cheating. On Ethereum, according to ethereum.org, a validator must deposit 32 ETH and run software that proposes blocks and attests to (votes on) other validators’ blocks. Time is divided into 12-second slots, grouped into epochs of 32 slots.

Rewards are paid in newly issued ETH and a share of transaction fees. Penalties come in two kinds. ethereum.org says: “Validators that go offline miss rewards and lose small amounts of ETH”. More serious, provable misbehaviour — such as signing two conflicting blocks — triggers slashing, covered below. Our glossary entry on proof of stake gives the short definition.

What are the ways to stake?

ethereum.org says: “You'll need at least 32 ETH to activate your own validator, but it is possible to participate with less.” It describes four main routes:

Home staking is the most direct: “Nothing stands between you and the protocol: you hold your own keys”. With staking as a service you still deposit your own 32 ETH but a third party runs the node; ethereum.org notes that “Delegated staking always means trusting someone else with part of your staking setup.” Pools let many smaller holders combine their ETH; many issue a liquid staking token that represents your staked ETH and can be traded or used elsewhere in DeFi.

Is staking through an exchange different from staking yourself?

Yes, in who holds your crypto. On an exchange you hand your coins to a company, which stakes them and passes on rewards on its own terms. That is simple, but it means custody risk. The US Securities and Exchange Commission (SEC) warns: “If the third-party custodian is hacked, shuts down, or goes bankrupt, you may lose access to your crypto assets.” It also says that depositors “might cease to have legal ownership of those assets and might not be able to get those assets back when they want to.”

ethereum.org adds a network-level concern about exchanges: “This can be dangerous for the network and its users as it creates a large centralized target and point of failure, making the network more vulnerable to attack or bugs.”

Staking yourself avoids the custodian but puts the technical work — and the consequences of mistakes, lost keys or downtime — on you. Pooled staking sits in between; ethereum.org sums up its risks as “a combination of counter-party, smart contract risk and execution risk”. Read our guide to crypto wallets and private keys before choosing.

What is slashing?

Slashing is the heaviest penalty in proof of stake. ethereum.org explains that provable misbehaviour, such as signing two conflicting blocks, results in slashing: “part of the validator's stake is destroyed” and the validator is forcibly removed from the network.

If you stake through a pool, operator or exchange, a slashing event caused by their setup can hit your stake too, depending on their terms. Ask whether a provider covers slashing losses, and read the terms rather than the marketing.

Can you unstake whenever you want?

Not always straight away. Staked ETH could not be withdrawn at all until the Shanghai/Capella upgrade on 12 April 2023. Today, ethereum.org says a validator wanting its full balance back must make a “voluntary exit”, and the wait varies with how many other validators are leaving at the same time.

Exchanges and pools add their own rules: some have unbonding periods, some process withdrawals in batches, and in a crisis a platform can pause them. Liquid staking tokens let you sell your position instead of waiting — but only at whatever price the market offers that day, which can differ from the value of the underlying ETH. Plan on the basis that staked crypto may not be available exactly when you need it.

Do staking rewards protect you if prices fall?

No. Rewards are paid in the same token you staked, so they do nothing about that token’s price.

Illustrative example (hypothetical numbers, not a forecast): you stake 1 ETH bought for £2,000 and earn a hypothetical 3% in ETH over a year, giving 1 × 1.03 = 1.03 ETH. If the price of ETH falls to £1,600, your position is worth 1.03 × £1,600 = £1,648 — down (2,000 − 1,648) ÷ 2,000 = 17.6%. The UK Financial Conduct Authority (FCA) gives its own example: Ethereum fell 42.49% between 24 August and 1 December 2025. Our guide to crypto volatility explains why such swings are common.

What do regulators say about staking?

United States. On 29 May 2025 the SEC’s Division of Corporation Finance said: “It is the Division's view that “Protocol Staking Activities” (as defined below) in connection with Protocol Staking do not involve the offer and sale of securities within the meaning of Section 2(a)(1) of the Securities Act of 1933 (the “Securities Act”) or Section 3(a)(10) of the Securities Exchange Act of 1934 (the “Exchange Act”).” The same statement says it “has no legal force or effect”, and that it “does not address all forms of “staking,” such as so-called “liquid staking,” “restaking” or “liquid restaking.”” SEC staff issued a separate view on certain liquid staking on 5 August 2025; Commissioner Caroline Crenshaw responded the same day with a statement titled “Caveat Liquid Staker”, stressing that it reflected staff views only. None of this is a safety rating for any staking service.

United Kingdom. The FCA’s June 2026 overview of its crypto regime says on staking: “We are maintaining the overarching approach to strengthening retail consumer understanding, including requirements for disclosures, contractual terms and client consent.” The FCA says the regime’s full scope expands from 25 October 2027. Until then, check any provider on the official registers.

What are the risks of staking?

• Price risk. The staked token can fall far more than any reward earned (see the example above).
• Penalties and slashing. Downtime costs small amounts; provable misbehaviour can destroy part of the stake (ethereum.org).
• Custody and counterparty risk. With an exchange or custodial service, its hack, shutdown or bankruptcy can cost you access (SEC).
• Smart-contract risk. Pools and liquid staking tokens run on code that can contain flaws (ethereum.org).
• Lock-ups and queues. You may not be able to get your crypto back when you want it.
• Liquid staking token prices. These tokens trade at market prices that can differ from the value of the staked coins.
• Scams. Offers promising high, fixed staking returns are a classic red flag — see our crypto scam red flags.
