The First Permissionless
Perpetual Futures Protocol
on Ethereum L1
Leverage is synthesized from volatility redistribution. No lending. No margin. No liquidation penalties. Up to 50x on any ERC20 token.
How Mercantile Works
Every asset has natural price volatility. Mercantile restructures who experiences it. Two groups deposit into a shared pool: counterparties accept a fixed-value position and give up their exposure to price swings, while leveraged traders absorb that surrendered volatility, amplified by their chosen leverage. When the underlying asset moves 1%, a 10x position moves roughly 10%, not because anyone borrowed, but because the volatility that would have been spread across all holders is concentrated into fewer hands. This is volatility redistribution: leverage without debt or margin.
The Mechanism
Two Sides of Every Pool
Two Sides of Every Pool
Each market has a Long pool and a Short pool. Inside each pool, counterparties accept a fixed-value position while leveraged traders take amplified exposure.
- Counterparties surrender price volatility for a fixed-value position
- Leveraged traders receive that volatility, amplified by their tier's weight
- The pool's total reserves minus the counterparties' fixed claims equals the leveraged residual, the portion that expands and contracts with price
- If the underlying asset moves 1%, a 10x tier moves roughly 10%, not from borrowing, but from volatility redistribution
- Total volatility in the system is unchanged, just reallocated between participants
Leverage Tiers
Leverage Tiers
The leveraged residual is split across tiers from 2x to 50x by weight. Higher tiers claim a proportionally larger share of every price move.
- Each tier's weight determines its share of gains and losses
- Effective leverage depends on tier weight and pool utilization
- At 80% utilization with balanced composition, leverage matches the tier name
- Below target utilization, leverage compresses toward 1x, a built-in safety property
Dynamic Funding Rate
Dynamic Funding Rate
A continuous funding rate incentivizes the pool toward equilibrium. The rate adjusts based on utilization to attract whichever side the pool needs more of.
- Pool needs more counterparties? Leveraged side pays funding, incentivizing new counterparty deposits
- Pool needs more leverage traders? Counterparties pay funding, incentivizing new leveraged positions
- At equilibrium, funding rate is zero and neither side pays
- Long and Short pools have independent funding rates
Tier-Level Wipeouts
Tier-Level Wipeouts
When a tier's total value hits zero, the entire tier wipes and resets. There is no maintenance margin to monitor, no margin call that force-closes you, and no keeper bot racing to liquidate you at the worst moment. If the tier survives a drawdown, so does your position.
- Traditional perpetual futures need keepers because each position has a margin account that must be individually monitored
- Mercantile has no margin accounts. Tier wipeout is determined by aggregate tier value
- After wipeout, the tier resets with a new epoch, a clean slate for new deposits
- No keepers, no liquidation penalties, no MEV. The pool self-enforces solvency on every transaction
How It Compares
| CeFi Perpetuals | DeFi Perpetuals | Mercantile | |
|---|---|---|---|
| Leverage source | Exchange extends margin | LP pool lends liquidity | Volatility redistribution |
| Liquidation | Individual, with penalty | Individual, via keeper bots | Tier-level only, no penalty |
| MEV / keeper extraction | N/A (centralized) | Keeper bots extract MEV | None |
| Auto-deleveraging (ADL) | Yes: can force-close winners | Varies by protocol | None |
| Insolvency risk | Insurance fund depletion, ADL | LP pool depletion | No systemic insolvency: tiers absorb losses naturally |
| Counterparty exposure | Exchange insolvency risk | Passive LPs absorb PnL | Fixed notional, insulated from PnL |
| Custody | Centralized | Self-custodial | Self-custodial |
| Settlement layer | Centralized exchange | L2 or appchain | Ethereum L1 |
| Market creation | Permissioned | Governance gated | Permissionless |
Using Mercantile
Trade
Pick long or short. Choose up to 50x leverage. Deposit the pool's reserve token and receive shares.
Swap
Sell volatile assets for USDMX or buy with USDMX at exact Pyth oracle spot price, zero slippage within capacity.
Earn
Deposit as counterparty. Earn funding yield when the pool needs more counterparty capital. Withdraw at any time.
Exit
Close any position by burning shares. Set a minimum output for slippage protection. Receive reserve tokens at current value.
Why Choose Mercantile?
Existing perpetual futures protocols create leverage through lending or margin, then build complex liquidation engines, keeper networks, and insurance funds to contain the insolvency risk that lending creates. Mercantile replaces all of it with a single primitive: volatility redistribution.
Permissionless Market Creation
Deploy a perpetual market for any ERC20 token with a Pyth price feed. No governance vote. No risk committee. No liquidity bootstrapping. The first permissionless perpetual futures protocol, in the same way Uniswap allowed anyone to create a spot trading pair.
USDMX: On-Chain Delta-Neutral Stablecoin
Like Ethena's USDe, USDMX is backed by a delta-neutral basis position that earns funding yield. Unlike Ethena, the position is fully on-chain and self-custodial. No CEX short positions, no third-party custodians, no off-chain infrastructure. Every reserve balance is verifiable.
During negative funding, instead of draining a reserve like Ethena, the Comptroller converts volatile reserves to stablecoins, building permanent overcollateralization over time. The mint/redeem flow is itself a zero-slippage spot exchange at oracle price, not just a yield product.
Ethereum L1
Deployed natively on Ethereum mainnet. Maximum security, full composability, no bridge risk.
No Keeper Bots, No MEV
The pool self-enforces solvency on every transaction. No external actors, no extraction, no race conditions.
No Margin Accounts
No margin to maintain, no margin calls, no liquidation penalties. Your position survives any drawdown the tier survives.
Perpetual Futures
Long or short any ERC20 token with up to 50x leverage. No margin. No borrowing.
- Up to 50x leverage through volatility redistribution
- No margin calls, no liquidation penalties, no forced closures
- No keeper bots, no MEV extraction
- Higher tiers amplify gains and losses proportionally
Zero-Slippage Exchange
Buy or sell volatile assets at Pyth oracle spot price with zero price impact.
- Execute at exact oracle price, zero impact within available capacity
- USDMX is backed by protocol-managed counterparty positions
- No AMM curve, no order book spread, no price discovery cost
- Capacity scales with leverage trading demand
Counterparty Yield
Provide counterparty liquidity and earn dynamic funding yield from leverage traders. Withdraw anytime.
- Dynamic funding yield that scales inversely with pool utilization
- Self-correcting yield: the more the pool needs counterparty capital, the higher the funding rate rises to attract it
- Fixed notional claim: exposure is to funding rate, not price direction
- Withdraw anytime, no cooldown period, no withdrawal queue
From Perpetuals to a Financial System
Volatility redistribution isn't just a mechanism for perpetual futures. It's a primitive that produces new financial instruments. Long pool counterparties hold a synthetic dollar position by design. For approved collateral types, the Comptroller tokenizes this into USDMX: a fully on-chain stablecoin. Apply the same logic to Short pool counterparties and you get the inverse: synthetic assets like mxETH, mxBTC, mxNVIDIA, and mxGOLD, each providing tokenized 1:1 price exposure backed by USDMX.
Permissionless. Global.
Deployed on Ethereum L1. Accessible to anyone, anywhere. No gatekeepers, no jurisdictional restrictions, no permission required.
