protocol identification
two sources## Identification — Inverse Finance FiRM
- Name: Inverse Finance FiRM (Fixed-Rate Market); not a separate protocol named “inverse-firm.”
- Website / app:
firm.inverse.finance; parent siteinverse.finance. Docs:docs.inverse.finance. - Category: Isolated, overcollateralized fixed-rate lending/CDP market: users post collateral, hold DBR, and borrow DOLA.
- Launch: DAO authorization was executed December 16, 2022; DBR launched concurrently.
- Chains: FiRM launched on and is documented on Ethereum. The broader Inverse ecosystem has multichain token/bridge deployments, but I found no confirmed FiRM market deployment outside Ethereum.
- Tokens: INV is the governance token; DOLA is the borrowed stablecoin; DBR is the borrowing-rights token that represents fixed-rate borrowing capacity. ### Contracts and verification The documentation lists these Ethereum addresses: INV
0x41d5…dfb68; DOLA0x8653…c9ce4; DBR0xad03…d5d710; BorrowController v40x01EC…E4ce8; Oracle0xabe1…0cce8; FiRM Fed0x2b34…90fd; and market examples including WETH0x63df…7035, wstETH0x3FD3…50BC, and CRV0x63fA…A1Ee8. Required two-source cross-check including Dune: Not verifiable as of October 20, 2026. Dune MCP was unavailable in this run; therefore no on-chain verification, Dune query ID/execution ID, or complete explorer cross-check is asserted. DBR has an Etherscan address page, but that is insufficient for the requested multi-source validation. ## Fork lineage FiRM is not evidenced as a direct Compound fork. Its architecture is purpose-built around isolated personal collateral escrows, DBR accounting, DOLA Feds, and market-specific contracts. Inverse’s earlier Anchor money market *was* explicitly forked from Compound, with a changed oracle and added synthetic-asset/Fed logic. FiRM reports Code4rena and Nomoi audits; the available Nomoi report reviewed a specific commit, so audit coverage should not be assumed to cover later changes. Similar Compound-derived forks have suffered malicious or unsafe-modification incidents, including Cream, Rari Fuse, and Sonne; this is relevant lineage risk, not evidence that FiRM itself was modified maliciously.
