Mars Protocol

Mars Protocol is a decentralized lending and credit platform in the Cosmos ecosystem that operates via an “outpost” model across Neutron and Osmosis — combining a money market (Red Bank) with Credit Accounts that allow leveraged trading, yield farming, and cross-chain borrowing without requiring assets to leave the user’s control on-chain.

Overview

Mars Protocol launched on Terra in 2022 before the Terra collapse, then rebuilt and relaunched on Cosmos hub-secured Neutron and Osmosis in 2023. Mars’s architecture is explicitly multi-chain from the start: a core Hub contract (deployed on Neutron) serves as the risk-parameter controller, while Outpost contracts on Osmosis and other chains handle local lending markets. This allows Mars to offer lending on each chain while maintaining unified governance and risk management from a single hub.

Red Bank

Red Bank is Mars’s core money market:

Structure

  • Lending — users deposit assets (ATOM, USDC, stATOM, OSMO, etc.) and earn interest from borrowers
  • Borrowing — overcollateralized loans against deposited assets
  • Over-collateralization — borrowers must maintain LTV ratios (e.g., 75% max LTV for OSMO, 80% for ATOM)
  • Liquidations — positions below maintenance LTV are liquidatable by bots; liquidator receives a liquidation bonus

Supported Assets (Neutron/Osmosis)

On Neutron: USDC (axelar), ATOM, NTRN, stATOM, wstETH.USDC

On Osmosis: OSMO, ATOM, USDC, stOSMO, AKT, JUNO (varies by governance)

Credit Accounts

Credit Accounts are Mars’s advanced product:

What They Are

  • Users open a Credit Account — a sub-account with its own position tracking
  • Unlike standard lending, Credit Account borrows are used within Mars’s universe of strategies
  • Assets in a Credit Account can be simultaneously: lending collateral + LP position + leveraged trade

Leveraged Farming

  1. User opens Credit Account, deposits OSMO as collateral
  2. Borrows USDC against OSMO collateral
  3. Deploys both OSMO and USDC into OSMO/USDC Astroport or Osmosis pool as LP
  4. Earns LP fees + ASTRO/OSMO emissions on leveraged position
  5. Health factor monitored continuously; auto-liquidated if below minimum

Perp-Adjacent Strategies

Credit Accounts can run strategies analogous to leveraged perps:

  • Long ATOM via borrow-to-buy
  • Short ATOM via borrow ATOM → sell → wait for price drop → buy back → repay
  • Without a true perp matching engine, these are lending-based leverage positions

Hub and Outpost Architecture

Mars’s cross-chain design:

  • Mars Hub (Neutron) — holds global risk parameters, governance votes, oracle validation logic
  • Outposts (Osmosis, etc.) — local Red Bank contracts, Credit Account managers, and liquidation bots
  • IBC coordination — Hub pushes updated risk parameters to Outposts via IBC messages
  • Allows one protocol governance (MARS token holders) to control risk across multiple chains without requiring each chain to run independent governance

MARS Token

  • Governance — MARS holders vote on Hub governance (risk parameters, new outpost approvals, fee settings)
  • Staking — MARS staked in the Safety Fund backstops bad debt; stakers earn a share of protocol fees
  • Safety Fund — MARS staked as insurance; slashed to cover bad debt events (similar to Aave’s Safety Module)
