What is cETH?

cETH is a “cToken” within the Compound Finance protocol, with the full name Compound Ether. It is a token that represents the Ethereum (ETH) users deposit into the Compound protocol to earn interest. When users deposit ETH into the Compound protocol, they receive a corresponding amount of cETH as proof of their deposit.Over time, the redemption rate of cETH gradually increases, reflecting the interest earned on the ETH it represents.

cETH (Compound ETH) 简介：获取方式与核心作用

  • Interest Accrual: The value of cETH increases as ETH lending and borrowing activities within the protocol continue, meaning users holding cETH automatically earn interest without needing to take any action.
  • Fungibility: All cETH are fungible and can be traded on secondary markets (such as decentralized exchanges).
  • Collateral: cETH itself can also be used as collateral within the Compound protocol to borrow other crypto assets.

Main Ways to Obtain cETH

Unlike mainstream cryptocurrencies such as Bitcoin or Ethereum, cETH cannot be “purchased” directly on most centralized exchanges. The primary way to obtain it is through direct interaction with the Compound protocol.

1. Supply ETH via the Compound Finance protocol

This is the most direct and primary method of obtaining cETH. The specific steps are as follows:

  1. Connect your wallet: Visit the official Compound Finance website and connect to the protocol using a compatible Web3 wallet (such as MetaMask).
  2. Select ETH: Locate the ETH market on the protocol interface and select the “Supply” option.
  3. Deposit ETH: Enter the amount of ETH you wish to deposit and confirm the transaction. Once the transaction is successful, you will receive the corresponding amount of cETH in your wallet. This cETH represents the ETH you deposited and the interest it will generate in the future.
  4. Withdraw ETH: When you wish to retrieve your ETH, simply select “Withdraw” in the Compound protocol and redeem your cETH. The protocol will return your ETH, along with the accumulated interest, based on the current exchange rate.

2. Trading on Decentralized Exchanges (DEXs)

Although not the primary method, cETH can be traded for other cryptocurrencies on some decentralized exchanges (DEXs), such as Uniswap, SushiSwap, and others. Users can acquire cETH by following these steps:

  • Find a trading pair: Search for trading pairs between cETH and other major tokens (such as ETH, USDC, etc.) on the DEX.
  • Execute a trade: Connect to the DEX using your Web3 wallet and execute the swap.

Please note that cETH liquidity on DEXs may not be as deep as when interacting directly with the Compound protocol, and trading slippage and fees may be higher.

The Core Role of cETH

cETH plays a vital role in the decentralized finance (DeFi) ecosystem:

  • Interest Earnings: It allows ETH holders to earn passive income by depositing their assets into lending protocols.
  • Liquidity: As a tradable token, cETH provides additional liquidity for deposited ETH, allowing users to sell their cETH without redeeming the underlying ETH.
  • Composability: cETH can interact with other DeFi protocols, such as serving as collateral to borrow from other protocols or participating in liquidity mining.
  • Standardization: The cToken model provides a standardized interface for borrowing and lending various assets, promoting interoperability within the DeFi ecosystem.

Important Notice

Participating in DeFi protocols and holding cETH involves certain risks, including smart contract risks, market volatility risks, and liquidation risks. Before taking any action, please be sure to understand the relevant mechanisms and potential risks.
