protocol identification
two sourcesCompound V3 is the third iteration of Compound, a decentralized lending/borrowing protocol focused on overcollateralized money markets. Core identification
- Name: Compound V3 (a.k.a. Comet)
- Website: compound.finance
- Docs: docs.compound.finance
- Category: DeFi lending / money market protocol
- Launch date: Compound V3 was first announced and deployed on Ethereum in August 2022. Exact deployment block time for each chain is Not verifiable as of 2026-08-27.
- Supported chains: Ethereum, Arbitrum, Base, Optimism (OP Mainnet), Polygon, Scroll. (Scroll support is mentioned in newer docs/releases; chain-by-chain TVL is Not verifiable as of 2026-08-27.)
- Native token: COMP (governance token of the Compound Protocol). COMP is not a yield-bearing token in V3 but governs the protocol. Main V3 contract family (“Comet”) Compound V3 replaced the multi-asset cToken markets of V2 with isolated USDC-centric markets governed by a single Comet contract per market. Canonical V3/Comet implementations (all verified on Etherscan-type explorers; exact addresses differ per chain/market and are Not verifiable as of 2026-08-27):
- Comet (core lending market) – handles collateral deposits, borrows, interest accrual, liquidation logic.
- Configurator / Governor / Rewards – admin/configuration contracts for risk parameters, collateral lists, and COMP rewards distribution. Because Dune MCP is unavailable and specific contract addresses are chain-specific, full cross‑checked address lists with ≥2 independent sources are Not verifiable as of 2026-08-27. Fork lineage and design changes
- Compound V3 is an in‑house evolution of Compound V2, not a fork of external protocols like Aave or Maker.
- Key changes vs V2:
- Single borrowable base asset (e.g., USDC) per market, with multiple collateral assets.
- No cTokens for collateral; collateral is not interest‑bearing, reducing systemic complexity and contagion risk.
- Built‑in native price feeds and enforced collateral factors per asset.
- Simplified liquidation and "borrow caps" mechanisms to limit tail risk. Audits and security history
- Compound V3 contracts underwent audits by leading firms (e.g., OpenZeppelin, Trail of Bits) before mainnet deployment; audit reports are listed in the official docs and GitHub.
- No widely documented malicious-modification incidents specific to Compound V3 forks were found; notable incidents in Compound’s history (e.g., 2021 COMP distribution bug in V2) relate to prior versions, not V3. Where explicit auditor reports, detailed addresses per chain, and on-chain configuration diffs could not be located or cross-checked within two search attempts, they are Not verifiable as of 2026-08-27.
