什么是 CeFi？
Centralized Finance (CeFi) refers to cryptocurrency platforms run by companies that act as intermediaries between users and financial services. Think of CeFi as the traditional banking model applied to crypto: you create an account, verify your identity, deposit funds, and the company manages everything on your behalf.
最知名的CeFi平台，如Binance、Coinbase、Kraken和Crypto.com，都是中心化交易所（CEX）。它们运行订单簿、持有用户资产、处理提现，并遵守其运营所在司法管辖区的规则。当你在Coinbase上购买比特币时，该交易所会将比特币存放在自己的钱包中，直到你将其提取。.
CeFi also includes lending platforms (historically BlockFi, Celsius and Nexo), payment services and custody providers. The common thread is a trusted third party that controls your funds and executes transactions for you. This model offers convenience and a familiar experience, but it comes with a basic trade-off: you must trust the company not to mismanage, lose or steal your assets.
托管
平台持有您的私钥并控制您的资金。您依赖其安全性和偿付能力。.
需要KYC
在您进行交易或提款之前，必须进行身份验证（护照、自拍、地址证明）。.
传统模型
运作方式类似于银行或经纪公司：客户支持、法币入口、受监管的实体并具备公司治理。.
什么是DeFi？
Decentralized Finance (DeFi) replaces intermediaries with smart contracts, programs deployed on blockchains such as Ethereum that execute on their own. Instead of trusting a company to hold and manage your funds, you interact directly with open-source code that anyone can inspect.
DeFi protocols cover most of the services found in CeFi: trading on decentralized exchanges (DEXs) such as Uniswap, lending and borrowing on Aave or Morpho, yield optimization on Beefy Finance, and stablecoin savings. The key difference: your assets stay in your own wallet until you choose to interact with a contract.
As ethereum.org describes it, DeFi is permissionless (anyone with a wallet can take part, with no identity check), composable (protocols can be combined like building blocks) and transparent (every transaction is recorded on a public blockchain). These properties make the system open and auditable, but they also introduce risks that CeFi users never meet.
非托管
您掌握自己的私钥。资金会保留在您的钱包中，直到您明确与智能合约交互。.
无许可
No identity check (KYC) and no sign-up form at the protocol level. Anyone with an internet connection and a wallet can take part, although some front-ends apply their own restrictions.
可组合
协议像积木一样相互连接。在Aave上借贷，在Uniswap上交换，并存入收益金库，所有这些都在一笔交易中完成。.
关键区别：DeFi 与 CeFi
The DeFi vs CeFi question is not about which is "better". It is about understanding the trade-offs so you can choose the right tool for your situation. Below is a side-by-side comparison across the dimensions that matter most.
| 维度 | CeFi | DeFi |
|---|---|---|
| 托管 | 平台持有您的资金 | 您持有自己的私钥 |
| 透明度 | 不透明，相信公司的说法 | 完全链上，可由任何人审计 |
| 访问 | 需要 KYC，地域限制 | 无许可，向所有人开放 |
| 费用 | 交易费用 + 提现费用 + 点差 | 燃气费 + 协议费（通常更低） |
| 速度 | 即时（内部账本） | 区块时间依赖（秒到分钟） |
| 收益 | Set by the platform, usually lower | 由市场供需决定，通常较高但可变 |
| 监管 | Licensed in many jurisdictions; protections vary by platform | Largely unregulated; the contract code sets the rules |
| 恢复 | 客户支持，密码重置 | 如果丢失密钥则无法恢复 |
CeFi 风险：中间人失效时
CeFi的核心承诺是便利：交出你的资产，一家值得信赖的公司将安全地管理它们。2022年的失败打破了许多用户的这一承诺。三个案例说明了为什么交易对手风险是中心化金融的决定性弱点。.
FTX: Customer Funds Diverted to Alameda
FTX was one of the largest cryptocurrency exchanges in the world. In November 2022, it collapsed within days after reports that Alameda Research, its sister trading firm, held a large part of its balance sheet in FTT, FTX's own token. Users rushed to withdraw. FTX could not pay them because, according to the SEC complaint of December 2022, customer funds had been diverted to Alameda without disclosure.
Founder Sam Bankman-Fried was convicted of fraud in November 2023 and sentenced to 25 years in prison in March 2024. Customers had to wait for the bankruptcy process to recover value. The lesson: a well-known CeFi platform can be insolvent behind closed doors, and you will not know until it is too late.
Celsius Network: Frozen Withdrawals, Bankruptcy
Celsius presented itself as a "bank for crypto" and advertised yields far above bank rates. Behind the scenes, according to the SEC, it deployed customer funds into risky and illiquid strategies while telling investors otherwise. When the market fell in June 2022 after the Terra collapse, Celsius froze all withdrawals, locking billions of dollars of customer assets.
The company filed for Chapter 11 bankruptcy in July 2022. In July 2023 the SEC charged Celsius and its founder, Alex Mashinsky, with fraud (see Sources). Users learned the hard way that high CeFi yields can come from undisclosed risk-taking.
BlockFi: Contagion from FTX
In February 2022, BlockFi agreed to a $100 million settlement with the SEC and state regulators over its unregistered interest accounts. Later that year the FTX collapse dealt the final blow. BlockFi had significant exposure to FTX and Alameda Research, and it filed for bankruptcy in November 2022, weeks after FTX. Users lost access to their funds while the bankruptcy ran its course. The episode shows that CeFi counterparty risk is contagious: one platform's failure can spread across the centralized ecosystem.
DeFi 风险：可能出现的问题
DeFi removes the company in the middle but introduces its own dangers. There is no customer support, no fraud protection and no regulatory safety net. If something goes wrong, the loss is usually final.
智能合约漏洞
Code can have bugs. Exploits have drained hundreds of millions of dollars from DeFi protocols. Audited contracts are not immune: audits reduce risk but cannot remove it. The Wormhole bridge exploit in 2022 and the Euler Finance exploit in 2023 are two well-documented examples.
预言机操纵
DeFi protocols rely on price oracles (such as Chainlink) to value assets. If an attacker manipulates the price an oracle reports, for example with a flash loan on a thin market, a lending protocol can be tricked into issuing undercollateralized loans or liquidating positions unfairly.
拉地毯
Malicious developers create tokens or protocols, attract deposits with high APY promises, then drain the liquidity and disappear. This is most common with unaudited projects on new chains. Check a protocol's audit history, team and total value locked (TVL) history before depositing.
复杂性 & 用户错误
DeFi需要技术知识：管理助记词、理解代币授权、处理gas费用以及判断协议风险。一次错误的交易（将代币发送到错误的地址、批准恶意合约）可能意味着永久损失且无法追回。.

在USDC上赚取7.50%年化收益率CeFi 与 DeFi 收益
A common reason people explore DeFi is the yield gap. A CeFi platform sets the APY it pays on stablecoins and keeps a margin to fund its operations. In DeFi lending markets, the rate is set by supply and demand, and most of the interest paid by borrowers goes to depositors. That often produces higher rates, but they move every day. The table shows where to read each live rate rather than a figure that would be stale within weeks.

|---|---|---|---|

| 币安 Earn | CeFi | 由 Binance 设定；分级，显示在 Earn 部分 | Flexible or fixed terms |

两全其美
The DeFi vs CeFi choice is often presented as a binary. In practice, a category of platforms combines DeFi-based yield with a CeFi-style user experience. These platforms interact with DeFi protocols behind the scenes and give users a simple interface to deposit, earn and withdraw.
Coinstancy is built on this model. Instead of asking you to manage a wallet, pay gas, assess smart contract risk and compound your returns by hand, Coinstancy handles that for you. You deposit USDC, and the platform allocates it to DeFi lending protocols to generate yield.
The result: 7.50% APY on USDC with Dollar Savings. Interest accrues every second and is automatically reinvested. There is no lock-up, and you can request a withdrawal at any time. You get access to DeFi yield without the wallet management, gas costs and protocol selection that keep many people on the CeFi side. Protocol, stablecoin and liquidity risks still apply; the Trust Center lists them.

初学者：从 CeFi 或桥接平台开始
如果您是加密货币新手，请从 Coinbase 等持牌交易所开始购买您的第一批资产。为了赚取收益，像 Coinstancy 这样的桥接平台可以让您在无需任何 DeFi 知识的情况下获得基于 DeFi 的收益（通过 Dollar Savings 在 USDC 上获得 7.50% 的年化收益率）。您可以避免钱包管理、gas 费用和协议评估的学习曲线。.
Priority: simplicity. Learn the fundamentals before exploring more complex strategies.
中级: 两者兼顾多元化
Once you understand how wallets and transactions work, consider splitting your portfolio. Keep trading assets on a CeFi exchange for convenience, and place stablecoins in DeFi lending protocols (or Coinstancy) for yield. One illustrative split: a smaller share on CeFi for active trading, a larger share in DeFi or bridge platforms for earning.
Priority: yield and diversification. Do not keep all your assets with a single custodian.
高级：原生 DeFi
Experienced users who understand smart contract risk, can evaluate protocol security and are comfortable with a hardware wallet can go fully on-chain. Interact directly with protocols such as Morpho and Beefy for direct access to protocol rates and full control of your assets.
Priority: control. Accept that you are your own bank, and your own risk manager.
