One Portfolio. Infinite Prospects.
Synthetix is bringing perps to Ethereum Mainnet in This autumn 2025, and one of the crucial vital options at launch will likely be multi-collateral margin. Merchants will be capable to submit a portfolio of property as margin, together with yield-bearing collateral, protecting these property productive whereas they commerce, and even between trades.
Ethereum is the pure residence for a feature-rich perp dex. It’s the place DeFi has the deepest liquidity, with greater than $90B locked throughout lending markets, staking protocols, and liquidity swimming pools. That depth and composability open the door to a wide range of margin property not potential on different chains, all with out Synthetix spending a dime on liquidity incentives or asking customers to bridge.
What’s potential with multi-collateral? Let’s break down one of the crucial compelling options of the upcoming Synthetix Mainnet and the way it advantages each person of the platform.
Supported Collaterals at Launch
At launch, Synthetix will assist three main collateral sorts:
sUSDe – Ethena’s yield-bearing artificial USD stablecoin, regularly reaching double-digit yield via a basis-trading technique. See present yields on DefiLlama.wstETH – Lido’s liquid staked ETH, which accrues staking yield in ETH. See present yields on DefiLlama.cbBTC – Coinbase’s Wrapped Bitcoin, offering BTC publicity, unlocking huge potential liquidity, and enabling environment friendly BTC basis-trading.
These property are simply the beginning. Synthetix Mainnet structure can assist practically any ERC-20 with enough liquidity on Ethereum.
Margin That Works for You
So how can merchants profit from these property? Whereas every margin sort and technique has distinctive threat, let’s discover some widespread approaches to utilizing multi-collateral. Please keep in mind these descriptions are usually not suggestions, and every dealer ought to develop their very own method on a person foundation.
Publicity from Spot, Perps, or Each
With multi-collateral, you don’t have to promote ETH, BTC, or sUSDe publicity to commerce. You may margin these property immediately, retaining upside and yield whereas opening perp positions. Which means:
Smarter margin selections: use ETH or BTC as margin when funding charges are excessive, lowering prices.Yield whilst you commerce: secure collateral like sUSDe or staking property like wstETH proceed to earn even when deployed as margin.Keep away from pointless capital beneficial properties: Commerce perps with out the necessity to promote your property and set off a taxable occasion.
Extra Environment friendly Foundation Trades
Multi-collateral unlocks highly effective arbitrage alternatives. For instance, a dealer can deposit wstETH and use it as margin to brief ETH perps in equal measurement. The result’s a delta-neutral place the place collateral beneficial properties and place PnL offset, lowering liquidation threat whereas stacking rewards:
Staking yield from wstETH.Constructive funding funds from the brief.
This makes foundation trades extra worthwhile and ensures tighter, extra aggressive funding markets throughout the change. Since foundation merchants hold funding charges in verify, each dealer on the change advantages when foundation merchants might be extra worthwhile and environment friendly.
Superior DeFi Methods
As a result of Synthetix is constructed on Ethereum, merchants can mix perps with probably the most liquid DeFi protocols. Methods like looping on Aave—borrowing in opposition to yield-bearing collateral to arbitrage the unfold between funding charges and borrowing prices—develop into a lot easier to handle with out the necessity to depend on bridges. With probably the most liquid lending markets in DeFi, Ethereum permits layered methods that merely aren’t potential elsewhere.

Tapping Into Billions in Idle Capital
The chance on Ethereum is very large. Lido’s wstETH alone represents over $15 billion in staked ETH. Coinbase’s wrapped property, together with cbBTC, are onboarding billions extra in institutional liquidity from different chains. Even a fraction of this capital used as margin can signify an unlimited alternative for Synthetix as we prepared the ground in constructing high-performance merchandise immediately on Ethereum.
The power so as to add new ERC-20 tokens as Synthetix scales opens the door to new partnerships with core Ethereum communities, permitting perps on Ethereum to sit down alongside lending markets as a important software in an Ethereum person’s toolkit for including leverage, hedging, and constructing customized payoffs.
Although Synthetix has modified through the years, our core mission to construct highly effective instruments for the Ethereum group has remained. Now, greater than ever, Ethereum builders should come collectively to construct the brand new monetary system we’ve all envisioned. Synthetix is prepared.
Early entry begins now, however that is only the start. Be a part of the Synthetix group as we construct the subsequent technology of perps infrastructure on Ethereum Mainnet.
