Compound Ether (CETH)
Key data
updated $0Compound Ether (CETH) is an interest-bearing token issued by the Compound protocol, a decentralized lending platform on Ethereum. When you supply ETH to Compound, you receive cETH in return, which represents your deposit and automatically accumulates interest over time. Think of it as a receipt that grows in value while your ETH is lent out to borrowers.
Frequently asked questions
What is cETH and how is it different from regular ETH?
cETH is a derivative token you receive when you deposit ETH into the Compound lending protocol. Unlike regular ETH, it doesn't just sit in your wallet — it represents your share of the lending pool and steadily accrues interest. When you redeem it, you get back more ETH than you originally deposited, thanks to the interest earned.
How does cETH work technically?
cETH is an ERC-20 token built on Ethereum and governed by smart contracts, so there's no central authority involved. The exchange rate between cETH and ETH increases over time as borrowers pay interest, which is how your deposit grows. All of this happens automatically on-chain, and you can redeem your cETH back for ETH whenever the liquidity is available.
How is cETH issued and what controls its supply?
cETH is minted only when someone supplies ETH to Compound and burned when they withdraw, so its supply directly mirrors the amount of ETH deposited in the protocol. There's no pre-mine, fixed cap, or separate tokenomics — the supply is purely demand-driven. Interest rates themselves are set algorithmically based on borrowing demand in the pool.
How can I store and use cETH?
Since cETH is a standard ERC-20 token, any Ethereum-compatible wallet like MetaMask or a hardware wallet works fine. You can hold it to keep earning interest, use it as collateral for borrowing other assets on Compound, or transfer it like any other token. Just remember that redeeming it back to ETH depends on available liquidity in the protocol.
