Dolomite

Dolomite is an Arbitrum-native decentralized money market and margin trading protocol combining isolated lending positions with Virtual Liquidity — a mechanism allowing deposited assets to simultaneously serve as lending collateral and provide liquidity to AMMs, effectively enabling users to earn multiple yield streams from a single deposited token.

Overview

Dolomite launched on Arbitrum in 2023, later expanding to Berachain. It is differentiated by two interconnected innovations: a highly modular isolated margin lending system and Virtual Liquidity — a novel primitive that allows Dolomite’s money market deposits to also power external AMM liquidity without users needing to double-commit capital. This enables, for example, a user’s wstETH deposit to simultaneously serve as lending collateral (earning borrow interest) while that same wstETH provides LP liquidity to an AMM pool (earning swap fees).

Isolated Lending Markets

Dolomite’s core lending product features full position isolation:

Position Architecture

Each borrowing position is independent (“isolated”):

  • Risk isolation — a bad debt event in one asset market doesn’t spread to other markets (unlike Aave V2’s shared liquidity pools)
  • Multiple simultaneous positions — users can have several isolated positions open at once with different risk profiles
  • Global collateral — certain high-quality assets (ETH, wstETH, USDC) can be used as cross-position collateral

Supported Collateral in Arbitrum Markets

  • ETH and liquid staking derivatives (wstETH, rETH, weETH)
  • USDC, USDT, DAI
  • Arbitrum ecosystem tokens (ARB, GMX, GLP, etc.)
  • PT tokens from Pendle Finance (a key integration enabling depositing fixed-rate PT as collateral to borrow stablecoins)

Virtual Liquidity

Virtual Liquidity is Dolomite’s signature innovation:

How It Works

  1. User deposits wstETH into Dolomite as lending collateral
  2. Dolomite holds the wstETH but “wraps” virtual tokens representing it
  3. These virtual tokens are contributed to an AMM pool (e.g., a Dolomite-internal CLMM or external Camelot/Zyber pool)
  4. The AMM pool trades as normal using the virtually-backed liquidity
  5. Dual yield — user earns lending interest from borrowers using their wstETH as collateral AND LP fees from AMM trades that use their virtual liquidity

Why This Matters

Traditional AMM LP requires locking real tokens into a pool:

  • Tokens locked in an AMM cannot simultaneously be used as lending collateral
  • Virtual Liquidity breaks this constraint — same tokens serve two purposes simultaneously
  • Capital efficiency improvement: 1 token doing the work of 2 positions

Limitations and Risks

  • Virtual Liquidity introduces novel smart contract complexity
  • AMM slippage and impermanent loss still apply to the LP portion
  • Novel mechanism with fewer years of battle-testing than traditional money markets

Pendle PT Collateral Integration

A distinctive Dolomite feature is accepting Pendle Principal Tokens (PTtokens) as collateral:

  • Users can deposit PT-weETH or PT-wstETH from Pendle into Dolomite
  • Borrow stablecoins or other assets against the PT collateral
  • Effectively leverages fixed-rate PT yield against borrowed stablecoins
  • Creates looping strategies: PT collateral → borrow USDC → buy more PT → repeat

DOLO Token

  • DOLO — Dolomite’s governance token
  • Distributed via liquidity mining to early Dolomite depositors and borrowers
  • Governance controls: risk parameters, asset whitelisting, Virtual Liquidity AMM integrations, fee rates

Berachain Expansion

Dolomite deployed on Berachain as one of the first major money markets:

  • Proof of Liquidity (PoL) — Berachain’s incentive system rewards protocols providing liquidity; Dolomite deposits qualify for PoL rewards
  • Positioned as Berachain’s native lending layer similarly to how Aave serves Ethereum
