protocol identification
two sourcesDolomite is a DeFi money market + margin trading + DEX protocol originally launched on Ethereum, now primarily associated with Arbitrum and later expanded multi‑chain. ### Identification
- Name: Dolomite
- Website / App: dolomite.io and app.dolomite.io (interface referenced in docs).
- Docs: Hosted at docs.dolomite.io, covering protocol overview and user guides.
- Category: Lending + margin trading + spot DEX (money market protocol with leveraged trading).
- Launch dates: Ethereum deployment around 2019; Arbitrum deployment in 2022.
- Chains (per off‑chain sources):
- Arbitrum One (main chain and focus).
- Ethereum L1.
- Berachain, Polygon zkEVM, Botanix, Mantle, X Layer mentioned as supported/expansion chains. On‑chain verification of those deployments: Not verifiable as of 2026‑08‑29.
- Native token: DOLO, described as an ERC‑20 governance/utility token. On‑chain token contract address and supply: Not verifiable as of 2026‑08‑29. ### Main contracts (high‑level)
- Multiple sources describe a core system called “Dolomite Margin”, a suite of Solidity smart contracts on Arbitrum for lending, borrowing, margin, and spot trading.
- Yield/analytics platforms list numerous “Dolomite [asset] Lending” markets on Arbitrum (e.g., WETH, DAI, USDC.e, LINK, WBTC, ARB, magicGLP, wstETH, tBTC, USDe, uniBTC, eUSD, ETH+, etc.), implying each asset market corresponds to a lending contract or configuration. Exact contract addresses, explorer verification status (verified source code / proxy patterns), and any Berachain / Ethereum deployment details: Not verifiable as of 2026‑08‑29. ### Fork lineage and modifications
- Multiple independent educational sources state Dolomite’s original upstream is dYdX Solo Margin, i.e., Dolomite began as a fork of dYdX’s Solo Margin protocol.
- Dolomite is described as extending this base with:
- broader token support (hundreds to 1,000+ assets across chains),
- integrated spot DEX and lending in one account‑based margin system,
- “virtual liquidity” architecture for capital efficiency.
- Audit status of Dolomite’s changes vs. dYdX:
- No independent audit report from a recognized auditor was identified in the retrieved data; therefore audit coverage of the forked and modified contracts is Not verifiable as of 2026‑08‑29.
- History of malicious modifications in similar forks (i.e., other dYdX Solo Margin forks): Not verifiable as of 2026‑08‑29 with the currently available information. All on‑chain facts (addresses, TVL, verification badges) are missing for this run and must be treated as unverified; any protocol or marketing descriptions sourced from Dolomite’s own site or Medium are unverified marketing claims unless corroborated by independent analytics or media.
