Staking, DeFi and crypto yields: how they work, where the return comes from, the risks

By Unicorn Private Research. Published 27 October 2026.

Where does crypto yield come from? A crypto yield is always paid by someone. In staking it comes from the network, which rewards validators with newly issued coins and transaction fees for securing the blockchain. In DeFi lending it comes from borrowers who pay interest, and in liquidity pools from traders who pay fees. When a yield is much higher than these sources can explain, it usually comes from token incentives, leverage or new deposits, and the risk is higher accordingly.

Staking: securing a proof-of-stake network

In proof-of-stake blockchains such as Ethereum, Solana or Cardano, validators lock coins as a guarantee and in exchange propose and confirm blocks. The protocol pays them with newly issued coins and a share of transaction fees. On Ethereum a validator needs 32 ETH; those who do not run one can delegate to a provider or use a pooled service (ethereum.org).

The rate depends on how much is staked: the more coins are locked, the lower the reward per coin. With 816,072 active validators and 44.1 million ETH staked, the indicated annual rate was about 2.44% on 27 October 2026 (validatorqueue.com). Part of the reward is new issuance, which also dilutes those who do not stake.

Ways to stake

• Solo staking: you run your own validator and keep the keys. Full control, technical work and responsibility for uptime.
• Delegated or pooled staking: a node operator runs the validator; on some networks you keep custody of the coins.
• Exchange staking: the platform stakes on your behalf and keeps a commission. Simple, but you take on custody risk and the exchange's rules on unstaking.
• Liquid staking: you receive a token representing the staked coins plus rewards, which can be traded or used elsewhere. The token can trade below the value of the underlying coins in times of stress.

APR, APY and what the advertised rate shows

Platforms quote yields in two ways. The annual percentage rate (APR) is the simple yearly rate; the annual percentage yield (APY) assumes that rewards are reinvested and compounded, so it looks higher for the same underlying return. Both are usually variable and calculated on past data. A displayed rate may also be gross of the provider's commission: an exchange or a staking service typically keeps a share of the rewards, and liquid staking protocols charge a fee as well.

The rate is expressed in the staked asset, not in dollars or euros. If ETH earns 2.44% a year but its price falls by 20%, the position is worth less in dollars at the end of the year, even after rewards. The reverse is also true, which is why staking adds to price exposure rather than replacing it.

DeFi: lending, liquidity pools and stablecoin yields

Decentralized finance (DeFi) is a set of applications run by smart contracts on public blockchains. In lending protocols, depositors supply assets and borrowers pay interest after posting collateral worth more than the loan; if the collateral falls in value, it is sold automatically. In liquidity pools on decentralized exchanges, depositors provide two assets and earn a share of trading fees, but when prices move they can end up with less value than if they had simply held the assets (impermanent loss).

Yields on stablecoins such as USDC or USDT come from the same sources: borrowers, often traders using leverage, or incentive tokens distributed by protocols. In the United States the GENIUS Act, enacted in July 2025, prohibits payment stablecoin issuers from paying interest or yield to holders simply for holding the coin; rewards offered by third-party platforms remain under debate (Perkins Coie, 2026).

The risks to understand

• Price risk: a 3% yield in ETH does not offset a fall in the price of ETH.
• Smart contract risk: a bug or an exploit in the code can drain a protocol.
• Slashing: validators that misbehave or sign twice lose part of their stake; with a provider, that loss can be passed to you.
• Unstaking delays: exits can take days or weeks, depending on the network queue.
• Custody and counterparty risk: centralized platforms that offer yield can fail. Celsius, which promised high returns on deposits, went bankrupt in 2022 and was charged by the SEC on 13 July 2023 (SEC press release 2023-133).
• Design risk: the algorithmic stablecoin TerraUSD lost its peg in May 2022; on 16 February 2023 the SEC charged its developer with fraud (SEC press release 2023-32).
• Liquidity of the position: in stressed markets, liquid staking tokens and pool positions can be hard to exit at fair value.
• Tax: in many countries staking and DeFi rewards are taxed when received; rules vary by country.

What regulators say

In the United States, on 29 May 2025 the SEC's Division of Corporation Finance stated that protocol staking as described (solo, delegated and certain custodial arrangements) does not involve the offer of securities, and on 5 August 2025 it took a similar view of certain liquid staking activities. These are staff statements, not Commission rules, and one commissioner dissented (SEC). In the European Union, MiCA regulates the providers that offer custody and services on crypto-assets but not fully decentralized protocols. After 1 July 2026, platforms without a MiCA authorization had to stop serving EEA clients; Binance, which has no MiCA authorization, restricted its services in the EEA from that date (Decrypt, June 2026).

Questions to ask before using a yield product

• Who pays the yield, and why would they pay it?
• Is the rate fixed or variable, and in which asset is it paid?
• Who holds the keys, and what happens if the provider fails?
• How long does it take to withdraw, and with which penalties?
• Has the code been audited, and has the protocol been exploited before?

Yields and Unicorn Club

Crypto investors who look for return beyond staking sometimes consider private company shares as well. Unicorn Club, the club for accredited investors organized by Unicorn Private LLC, accepts BTC, ETH, USDT and USDC (ERC-20) for its pre-IPO club deals; the guide on how to invest in pre-IPO companies with crypto explains how it works.

Frequently asked questions

Is staking the same as lending?

No. In staking the coins secure a network and the reward comes from the protocol. In lending the coins are given to borrowers who pay interest. On an exchange the two can look alike, so read the terms.

Is a high APY a sign of a scam?

Not always, but it needs an explanation. Ask who pays it: very high rates often come from new token issuance, leverage or new deposits, and they can fall or stop quickly.

Are staking rewards guaranteed?

No. They depend on network conditions and validator performance, they are paid in crypto whose price changes, and they can be reduced by slashing or provider fees.
