Synthetix helped define the earliest eras of DeFi, from some of the first derivatives on Ethereum with Synths to being among the earliest adopters of L2s. Now, with Synthetix Mainnet preparing to launch, the protocol is returning to Ethereum with a clean slate and a sharper focus.
At the center of this comeback is the SLP vault: a market making engine that prioritizes protocol-owned liquidity and puts SNX back at the core of securing the system.
What is the Synthetix Liquidity Provider (SLP)?
The Synthetix Liquidity Provider (SLP) vault is a community-owned, protocol-operated system that executes market making strategies on Synthetix Perps. Unlike traditional models reserved for exclusive counterparties, SLP allows anyone to deposit sUSD, earn a share of trading profits, and access top-tier fee discounts — all with no management or performance fees.
From launch, SLP will help ensure deep liquidity and tight spreads across all listed assets. By opening up one of the most lucrative sources of alpha in crypto, SLP makes market making accessible, transparent, and community-driven.
The enshrined asset of SLP is sUSD, Synthetix’s native stablecoin, backed by staked SNX. By using sUSD as the exclusive deposit asset, SLP creates stable, protocol-native liquidity and simplifies profit distribution. This design not only reinforces utility and demand for sUSD, but also puts SNX stakers back at the center of securing the system.
Here’s how sUSD powers the vault, how risk is managed, and what it means for depositors.
The Role of sUSD in the SLP Vault
sUSD is the exclusive deposit asset for SLP. Here’s how sUSD integrates with SLP:
Deposits: Users deposit sUSD to become liquidity providers, with deposits representing proportional vault ownership.  Stability: sUSD maintains a 1:1 value with USDT within the Synthetix Exchange, ensuring consistent trading and profit/loss calculations. This ensures stable, simplified accounting and fair profit distribution.Risk Management: SLP’s directional exposure will be hedged by a novel design (to be announced in due course!). If losses are incurred, the Exchange’s insurance fund can cover shortfalls. As a last line of defense, staked SNX can be slashed pro-rata and converted to USDT to cover shortfalls.
Optimal scenario
SLP aims to replicate the profitability of models like Hyperliquid’s HLP and dYdX’s Megavault, which have proven sustainable over time. Matching the performance of peers, SLP should accumulate USDT for distribution to liquidity providers, ensuring sUSD remains a seamless liquidity asset without circulating among traders as collateral.
Suboptimal scenario
To address potential short-term losses, SLP is supported by:Â Â
PnL buffer: SLP, like other traders, will be able to accrue negative PnL up to a limit. Short-term losses are expected to be offset by trading and liquidation fees.Synthetix Exchange Insurance Fund: In the case of material financial events (bad debt, oracle manipulations, etc), the Insurance Fund, funded by a share of exchange profits, covers shortfalls. This will initially be funded by the Treasury.Synthetix Safety Module: SNX stakers in the 420 pool act as the final backstop for exchange solvency. Should all other measures fail, SNX stakers will be slashed pro-rata to cover deficits. For doing so, they will earn incentives (e.g. revenue share from trading fees) in return.
How Does the SLP Vault Work?
SLP leverages market making strategies to provide liquidity and generate returns for depositors. Here’s a high-level overview of how it operates:
Community-Owned Liquidity Pool: Anyone can deposit sUSD to participate.Profit and Loss Sharing: PnL from SLP’s activities are shared among depositors proportionally. The vault operates without additional fees for depositors, maximizing returns for participants. Market Making and Liquidation Strategies: The operations and design of SLP involve:Placing buy and sell orders: SLP will dynamically place buy/sell orders to ensure deep markets and tight spreads.Liquidation management: SLP will take over positions and non-USDT collateral from traders who are liquidated and manage them appropriately to minimise risk.Revenue streams: From bid-ask spreads, liquidation fees, collateral exchange fees, funding rates, and a share of trading fees.Lock-Up Period: 4-day withdrawal period ensures vault stability and deters strategic gaming.  Robust Risk Management: Liquidation fees, and a share of trading fees mitigate risks inherent in single-exchange market making.
Looking Ahead
SLP enables anyone to participate as a ‘house’ market maker, enabling anyone to earn yield from a traditionally exclusive strategy.
Whilst SLP will only launch at Mainnet Launch, the pre-deposit campaign on Mainnet starts next week. This will be the earliest opportunity for traders to gain whitelist access and experience perps on Mainnet.
Stay tuned for future updates detailing the pre-deposit campaign and SLP:
