Compound v2 is Live

Transparent, fair, autonomous interest rate markets for all

Today, we’re thrilled to announce the public launch of Compound v2, an interest rate protocol intended to power the financial markets & applications of the future.

Compound v2 is running smoothly on the Ethereum mainnet, and now supports Ether, 0x, Augur, Basic Attention Token, Dai, and USDC.

Supplying liquidity to Compound is better than ever. Each market has its own cToken (cETH, cZRX…), which you’ll receive when you supply that asset to the protocol; cTokens represent your balance in Compound. View them in your wallet, program them, or send them to cold storage — it’s up to you!

Simply by holding cTokens, you’ll earn interest, which accumulates through the cToken’s exchange rate — over time, each cToken becomes convertible into an increasing amount of its corresponding token.

Compound is a Protocol

Compound is an open-source, autonomous, extensible protocol that runs 24/7 — perfect for developers looking to build products that help users earn interest, or finance their ambitions. We’re honored to launch with a few projects that have already integrated Compound v2:


Zerion is a portfolio monitoring & management tool for open finance, and allows users to seamlessly earn interest.

Coinbase Wallet

Coinbase Wallet is the easiest way to interact with Ethereum applications, and has integrated cToken balances.

Compound Dashboard

Compound Dashboard is our full-function product to interact with the Compound protocol, using Metamask or a web3 browser.


Opyn is a decentralized margin trading platform built on Compound, Uniswap, and Dai. It allows users to go long or short their favorite Ethereum assets.


InstaDapp provides a convenient Supply and Borrowing interface to Compound, alongside CDP and Uniswap support.

If you’re interested in building your own application, we’ve published full documentation for the protocol, market data APIs, and cToken design resources.

One of the many ways you can interact with the Compound Protocol

Compound v1

The original protocol will continue to be accessible through its Ethereum smart contracts, the legacy web interface, and manual operation. Over the next 4–8 weeks, borrow transactions will become disabled, while supply, withdraw & repay transactions will work in perpetuity.


Compound v2 was audited by Trail of Bits, and the protocol was formally verified in partnership with Certora. The Compound protocol depends on new technology that may contain undiscovered vulnerabilities; we encourage the community to audit our contracts and security.

If you have any questions, ideas, or issues, join us in Discord — we’d love to hear from you.
