Company profile
researched Aug 2026Compound (compound.finance) develops the Compound Protocol, an Ethereum smart contract system that lets blockchain accounts supply capital (Ether or ERC-20 tokens) or borrow assets against collateral. Users who supply assets receive cTokens, ERC-20 tokens whose balances represent ownership of a lending market; cToken contracts track balances and algorithmically set interest rates for borrowers. Core operations exposed by the cToken contracts are mint (supply capital), redeem (withdraw capital), borrow, and repay borrow.
The protocol's code base is public on GitHub under the compound-finance organization. Supporting documentation includes the Compound Whitepaper, which describes how the protocol works, and a Compound Protocol Specification written in plain language. The project maintains a Discord server for user questions and a dedicated security page and security contact address for vulnerability reports, along with a community contributing guide.
Traction
The compound-finance/compound-protocol GitHub repository shows roughly 2,000 stars and 1,300 forks across 78 commits.

Technology
The system is composed of several Solidity contracts. CToken holds the core lending and borrowing logic, while CErc20 and CEther add public interfaces for ERC-20 tokens and ether respectively; each cToken is ERC-20 compliant and is assigned an interest rate and risk model. The Comptroller is the risk model contract that validates permitted user actions and enforces that borrowers maintain sufficient collateral across all cTokens; it is deployed behind a Unitroller and updated following a ControllerGX naming schema. InterestRateModel contracts determine rates algorithmically from market utilization, with WhitePaperInterestRateModel as the initial model taking a base rate and slope parameter. Supporting libraries include Careful Math (safe math), ErrorReporter (error codes), Exponential (fixed-point decimals) and SafeToken (safe ERC-20 interaction). Development tooling uses yarn/npm, the saddle framework, a Docker image, Jest contract tests, a scenario-runner REPL for high-level integration tests, code coverage and linting; formal verification specifications written in the Certora Verification Language are maintained in a spec/formal folder to produce proofs or counter-examples against contract code. Contracts are deployed to Ethereum mainnet and test networks including Goerli and Rinkeby.
Go-to-market
Blockchain accounts and users seeking to supply crypto capital for yield or to borrow assets against collateral, plus developers integrating with or contributing to the open-source protocol.
