Umami Finance

Umami Finance is an Arbitrum-native structured yield protocol offering delta-neutral GLP vaults — automating hedging of the directional exposure embedded in GMX’s GLP liquidity token through on-chain derivatives positions, so depositors can earn GLP’s trading fee yield without sustained long or short market risk — with UMAMI as the governance token and mUMAMI (marinated UMAMI) distributing real protocol yield in USDC.

Overview

GMX’s GLP token provides Arbitrum DeFi with an exceptional source of real yield (15–30% APY from trading fees, funding rates, and liquidation revenue) but carries inherent directional risk: GLP is an index of crypto assets (wBTC, wETH, LINK, UNI, and stablecoins), so holding GLP means being long ETH and BTC. Traders who want GMX’s trading ecosystem yield but not market directional exposure face a gap. Umami Finance fills this gap with automated delta-neutral GLP vaults that hedge out the non-stable asset exposure using on-chain short positions, delivering the market-neutral GLP fee yield to depositors without the need for them to manually manage perpetual short hedges.

Core Product: Delta-Neutral GLP Vault

The main product offerings are described below.

What is GLP?

  • GLP is GMX’s liquidity provider token on Arbitrum
  • GLP depositors provide the counterparty to GMX’s leveraged traders
  • GLP holders receive 70% of all GMX trading fees + funding rates + liquidation profits
  • Downside: GLP composition is ~50-60% stablecoins + ~40-50% BTC/ETH/other crypto
  • ETH/BTC exposure means GLP holders take directional risk (lose when market drops, gain when market rises)

Umami’s Hedging Mechanism

Umami’s delta-neutral vault:

  1. User deposits USDC into Umami vault
  2. Vault mints GLP (buying the GLP index exposure)
  3. Vault opens on-chain perpetual short positions for the non-stable GLP components (ETH, BTC) sized to match GLP’s ETH/BTC weights
  4. Short position notional = GLP’s non-stable weight × total vault GLP value
  5. Net ETH/BTC exposure: +GLP long ETH/BTC − short ETH/BTC hedge = ≈ 0 (delta-neutral)
  6. Residual yield: trading fees, funding rates, liquidation revenue from GLP — minus short position funding costs

Yield Sources

Income:

  • GLP trading fees (70% of GMX platform fees — large volume platform)
  • GLP funding rate income from GMX (paid by leveraged traders)
  • GLP liquidation credits

Cost:

  • Short perpetual funding rate (paid to longs; increases in bull markets)
  • Rebalancing gas costs (hedge must be updated as GLP composition changes)

Net yield: In neutral/bear markets: strong positive yield (funding costs low, GLP fees remain). In bull markets: reduced yield or potentially negative if funding costs exceed GLP fees.

UMAMI Token

Governance:

  • Vote on vault strategies, supported yield sources, and protocol parameters
  • Multisig to DAO transition for contract upgrades

mUMAMI (Marinated UMAMI):

  • Stake UMAMI → receive mUMAMI
  • mUMAMI holders receive real yield distribution in USDC.e from Umami vault performance fees
  • Yield paid in stablecoins (not native UMAMI), consistent with “real yield” DeFi narrative
  • mUMAMI represents Umami’s primary value accrual mechanism

Additional Vaults

Beyond delta-neutral GLP, Umami has explored:

  • WBTC Vault — structured yield on wBTC exposure
  • WETH Vault — structured yield on wETH exposure
  • GLP Vault (raw) — non-hedged GLP yield for users who want full exposure with convenience
  • Glp Compounder — auto-compounds GLP rewards into more GLP

Risk Considerations

Funding rate risk — Short perpetual funding rates spike in bull markets; if ETH rises sharply, shorts pay high funding that can exceed GLP fee income, turning vault yield negative.

Rebalancing lag — GLP composition changes over time as GMX’s collateral usage shifts; hedge must rebalance to maintain delta neutrality. Rapid GLP composition shifts can create temporary delta exposure between rebalances.

Smart contract risk — Stack includes GMX (GLP minting/redemption), Umami vaults, and perpetual platform for shorts (multiple protocol dependencies).

Correlation risk — In extreme market scenarios, GLP and short position may both perform poorly (e.g., stablecoin depegging stresses GLP stablecoin component while simultaneously requiring increased hedge sizes).
