That depth and composability open the door to a wide range of margin belongings not attainable on different chains, all with out Synthetix spending a dime on liquidity incentives or asking customers to bridge.
What’s attainable 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

Please bear in mind these descriptions should 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 must promote ETH, BTC, or sUSDe publicity to commerce. You may margin these belongings instantly, retaining upside and yield whereas opening perp positions. Meaning:

Coinbase’s wrapped belongings, together with cbBTC, are onboarding billions extra in institutional liquidity from different chains. Even a fraction of this capital used as margin can symbolize an infinite alternative for Synthetix as we cleared the path in constructing high-performance merchandise instantly on Ethereum.
The flexibility 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 take a seat alongside lending markets as a crucial device in an Ethereum person’s toolkit for including leverage, hedging, and constructing customized payoffs.
Although Synthetix has modified over time, 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 part of the Synthetix group as we construct the subsequent era of perps infrastructure on Ethereum Mainnet.
