什么是 APY？
APY (Annual Percentage Yield) is the rate of return you earn on a deposit over one year, taking compound interest into account. Unlike simple interest, APY includes the interest you earn on previously earned interest. It gives a more accurate picture of what you actually receive.
In the United States, the Truth in Savings Act (Regulation DD) requires banks to disclose the APY on deposit accounts so that customers can compare offers on the same basis (see Sources). In crypto and DeFi, APY serves the same purpose: it lets you compare yields across protocols, pools and strategies with a single standardized number.
For example, if you deposit $10,000 into a DeFi lending protocol at 5% APY, you would earn about $500 over one year, assuming the rate stays constant and rewards are reinvested automatically. The key word is "about". DeFi rates move constantly with market conditions.
复利
APY includes the effect of compounding: earning interest on interest. The more often interest compounds, the higher the effective return.
标准化比较
APY normalizes returns across compounding frequencies, so you can compare a rate that compounds daily with one that compounds monthly.
DeFi 中的变量
Unlike bank rates, DeFi APY can change every block with supply and demand. The rate you see today may differ tomorrow.
APY 与 APR：What's 的区别？
APY and APR are often confused in crypto. Both express an annualized return, but they treat compounding differently, which can lead to different outcomes on the same deposit.
APR (Annual Percentage Rate) is the simple, flat interest rate over a year. If you earn 10% APR on $1,000, you get $100 after one year. Earned interest is not reinvested. Many DeFi protocols display APR when rewards must be claimed and restaked by hand.
APY (Annual Percentage Yield) accounts for compounding. If you earn 10% APR and interest compounds daily, your effective APY is about 10.52%. The gap widens at higher rates: 100% APR compounded daily equals about 171.5% APY.

APY 在 DeFi 中的工作原理
In banking, APY is simple: the bank sets a rate, and you earn that rate on your deposit. In DeFi, the rate is set by smart contract code that reacts to supply and demand, not by a central authority.
供需 & 驱动利率
On lending protocols such as Morpho, Aave or Compound, APY is set by the utilization rate of each market. When borrowing demand is high relative to deposits, rates rise to attract more lenders. When supply exceeds demand, rates fall. This happens automatically through formulas called interest rate curves, which each protocol documents (see Sources).
For example, if a USDC market has $100M deposited and $80M borrowed (80% utilization), its supply APY will be higher than a market at 30% utilization. This is why rates differ between protocols, chains and even between markets for the same token.
复利频率很重要
In DeFi, interest can accrue every block (about every 12 seconds on Ethereum). Claiming and reinvesting that interest often requires a transaction, which costs gas. This creates a trade-off: compounding more often earns slightly more, but each compounding transaction costs gas.
Yield aggregators such as Beefy Finance address this by pooling deposits and reinvesting for all depositors at once, which spreads the gas cost across many users (see the Beefy documentation in Sources). This is why the same base lending rate can produce a slightly higher effective APY through an auto-compounding vault.
激励层堆叠
Many DeFi protocols add token incentives on top of the base lending or LP yield. As an illustration, a USDC deposit might earn 3% base APY from borrower interest, plus 1.5% paid in the protocol's own token. The displayed "incentivized APY" is 4.5%, but the token portion moves with that token's price.
When you evaluate a yield, separate the base yield (from real economic activity) from the incentive yield (temporary, dependent on token price and emission schedules). Base yields are more durable; incentive yields tend to fade over time.
APY 计算器 & 实际案例
The formula to convert APR to APY is: APY = (1 + r/n)n - 1, where r is the annual interest rate (as a decimal) and n is the number of compounding periods per year. The two examples below are illustrative and use hypothetical rates.
示例 1：保守型稳定币
示例 2：收益优化金库
The compounding advantage over time: $10,000 at 5% simple interest for 5 years grows to $12,500. The same rate compounded daily (about 5.13% APY) for 5 years grows to about $12,840. That is $340 more from compounding alone, assuming the rate does not change. At higher rates and over longer periods, the gap widens.
加密年收益率来源于何处？
Knowing where a yield comes from is the most useful check you can make. Durable yields come from real economic activity. Fragile yields come from inflation and token emissions. Here are the main sources:
借贷利息
Borrowers pay interest to lenders. This is the most direct yield source in DeFi. Protocols such as Aave, Compound and Morpho match the two sides. The yield comes from real demand: traders borrowing for leverage and users borrowing against collateral.
交易费用
Liquidity providers on DEXs such as Uniswap, Balancer and Curve earn a share of trading fees. Every swap pays a fee (Uniswap v3 pools use tiers of 0.01%, 0.05%, 0.30% or 1%, per its documentation) that is shared among LPs in proportion to their deposit. Pools with high volume relative to their size earn more.
质押奖励
Proof of Stake blockchains such as Ethereum pay validators for securing the network. The reward comes from new ETH issuance plus transaction priority fees, and the rate falls as more ETH is staked. The live Ethereum staking rate is published on the Ethereum launchpad (see Sources). See our staking guide for details.
代币激励（谨慎）
Many protocols distribute their native token to attract liquidity. This can raise the displayed APY a lot, but it is inflationary: you are paid in tokens that may lose value as more are created. These incentives usually decrease over time as emission schedules taper. Discount incentive APY for the token's price risk.

During the 2020-2021 "DeFi summer", new farms often advertised APYs in the hundreds or thousands of percent, paid almost entirely in newly minted tokens. The market has matured since. The table below describes what drives the yield of each strategy and where to check the live figure; it does not quote rates, because they change daily:
| 策略 | Yield Profile (live rate at source) | 风险等级 | 收益来源 |
|---|---|---|---|
| 稳定币借贷（Aave，Morpho） | Low to mid single digits, moves with borrowing demand (protocol app, DefiLlama) | 低 | 借款人利息 |
| ETH Staking (Lido, Rocket Pool) | Low single digits, falls as more ETH is staked (Ethereum launchpad) | 低 | 网络验证 |
| 稳定币LP（Curve，Balancer） | Fee income plus incentives, depends on pool volume (DefiLlama) | 中等 | 交易手续费+激励 |
| 收益聚合器（Beefy，Yearn） | Underlying yield plus a compounding gain, minus vault fees | 中等 | 优化复利 |
| 波动性配对LP（ETH/USDC） | Higher fee income, offset by impermanent loss | 高 | 手续费+无常损失风险 |
| 杠杆策略 | A multiple of the base yield, with liquidation risk | 非常高 | 放大基础收益+清算风险 |

APY 风险 & 警示信号
Not all APY is equal. A high number can hide serious risks. Here are the main points to check before depositing into any yield-bearing position:
不可持续的代币发行
If most of the APY comes from a protocol token with little use, the yield will shrink as emissions decrease or the token price drops. Check what share of the APY comes from base economic activity and what share comes from incentives.
智能合约风险
Every DeFi protocol carries the risk of a smart contract bug. A higher APY often means newer, less reviewed code. Prefer protocols that have been audited by several firms and have run with large deposits for years.
无常损失
LP positions in volatile pairs can suffer impermanent loss if asset prices diverge. A 20% APY can be wiped out if one token moves 50% against the other. Stablecoin-only pairs carry much less of this risk, as long as both coins hold their peg.
锁定期 & 提现延迟

黄金法则
If you cannot identify where the yield comes from, you are the yield. A stablecoin APY far above what large lending markets pay, with no clear, verifiable source of economic activity (lending demand, trading fees), is a red flag. Anchor Protocol (about 20% on UST, which collapsed in May 2022), Celsius (withdrawals frozen in June 2022) and FTX (November 2022) all followed this pattern.
How to Improve Your Crypto APY Safely
There are sound ways to raise your effective yield without taking on unnecessary risk. Here are five approaches:
使用自动复利金库
Instead of claiming and restaking rewards by hand (which costs gas each time), use vaults that reinvest for you. The compounding gain is small at single-digit rates and larger at high rates; the bigger saving is usually the gas you no longer pay. Beefy Finance and Yearn are common options.
在多个协议之间分散投资
Do not put all your stablecoins in one pool. Split them across two or three established protocols to reduce smart contract risk. If one protocol is exploited, you lose only part of your position.
跨链比较
The same USDC lending rate can differ between Ethereum, Arbitrum, Base and other chains. Smaller markets and active incentive programs can push rates up on some chains. Use DefiLlama (see Sources) to compare live rates across chains.
监控利率变化
DeFi rates change constantly. Check your positions regularly, or use a service that manages allocation for you. Coinstancy Dollar Savings pays a fixed rate instead of a block-by-block variable one. The APY shown is the fixed rate currently in force. It may be revised as market conditions evolve; a new rate applies to existing balances as well as new deposits.
使用收益聚合平台
Coinstancy Dollar Savings takes a single USDC deposit. Your USDC first enters a secure multisignature wallet operated by Coinstancy before being deployed into the selected on-chain strategies. You earn 7.50% APY without managing DeFi positions, token approvals or gas yourself.
