Synthetix Mainnet

Synthetix is returning to Ethereum mainnet to launch a perps trade

Launching the primary perps DEX on Ethereum Mainnet

In 2019, Synthetix led the transfer to Optimism, as Ethereum wasn’t scaling quick sufficient. Whereas we solved scaling, what many people underestimated was the influence of liquidity fragmentation from the proliferation of Layer 2 blockchains. The L2-centric roadmap diluted consideration, exercise and capital away from Ethereum mainnet and ETH the asset.

This enabled extra chains like Solana to seize mindshare.

Lastly the tide is popping. Validatorscore builders, and even Vitalik are rallying the neighborhood to refocus on Mainnet.

The lacking part is DeFi tasks coming again to mainnet to leverage the rising block house capability, to ship distinctive merchandise which are optimized for safety and stability of Ethereum.

Mainnet is the place establishments are trying, the place ETF flows land, and is the house of RWAs and stablecoins. Ethereum Mainnet holds over half of all DeFi worth, greater than seven instances that of any L2. Regardless of this worth dominance, only a few novel protocols have launched on mainnet since L2s grew to become prevalent, excluding EigenLayer and Ethena.

Synthetix is coming house once more. This implies eliminating all of the technical debt that’s collected during the last 4 years, together with ceasing all operations on L2s, redesigning staking (completed), closing legacy swimming pools, and many others.

Synthetix has been battle-tested in DeFi since 2017, pioneering artificial belongings, liquidity incentives and yield farming and decentralized stablecoins. After years of championing and focusing product improvement on main L2s, we’ve seen and felt their limitations. Synthetix is returning to its Ethereum Mainnet roots, the place DeFi was born, to launch a perps trade. One thing that nobody has tried since perpetuals grew to become the dominant monetary product in crypto.

Competing with centralised exchanges

As just lately as final 12 months, Synthetix prioritized onchain decentralization above all else, even person expertise. This uncompromising idealism hampered our skill to construct elegant merchandise. We have been constructing for an ideologically aligned viewers, however unable to scale previous early adopters, not to mention a wider crypto viewers. We chased ideological purity, whereas customers chased velocity and ease.

We’ve realized the onerous approach that person expertise is non-negotiable. No diploma of decentralization, both actual or perceived, can overcome clunky interfaces or poor efficiency. If DeFi feels clunky, customers will stick to acquainted centralized platforms.

To draw the subsequent wave of capital and problem incumbents, we should optimize for person expertise, whereas remaining non-custodial, so we don’t turn out to be CeFi.

Let’s be sincere: everybody in DeFi is competing with centralized exchanges.

Infinex has confirmed it’s potential to ship onchain, non custodial merchandise with distinctive person expertise.

Our job now’s to make Mainnet buying and selling so intuitive that customers overlook it’s onchain, assembly them the place they’re, not the place we want they have been. Thankfully, Synthetix has a protracted historical past of fixing tough onchain challenges.

Rising chaininess

Synthetix has realized that with the intention to win we have to personal the client expertise, supply an orderbook as a substitute of an AMM, and deploy on Ethereum mainnet as a substitute of L2s.

Regardless of years of attempting to make onchain AMMs work for perps, orderbooks supply higher liquidity and dealer expertise. Whereas orderbooks can’t presently be run on mainnet, Ethereum is the perfect place to custody, and settle, with out the bridge dangers or liquidity fragmentation.

With a purpose to return to mainnet, we’re utilizing a special structure to something earlier than, with offchain order matching, and batch settlement onchain:

  • L1 Custody and Settlement: Customers don’t need to bridge massive quantities to L2, so we’re utilizing L1. Consumer funds are custodied on L1, and trades settle on to L1. Dealer margin is managed by the offchain orderbook (for now), however onchain withdrawals are permissionless.
  • Offchain Matching Engine: Institutional-grade exchanges demand high-throughput, low-latency, fault-tolerant matching engines. Neither L2s or Solana, nevermind Ethereum, have adequate throughput to run an identical engine onchain. Our offchain engine delivers the efficiency skilled and discerning merchants anticipate.

As Ethereum scales, extra performance will migrate onchain, and is the first vector of decentralization.

“The Relaunch”

That is the largest Synthetix launch in historical past, and we’re placing up [redacted] SNX tokens in the direction of launch incentives. SNX tokens shall be earned from factors, which begin accruing in Section 0 of the marketing campaign, starting with sUSD and sUSDe predeposit vaults.

500 early entry invite codes shall be issued to sUSD and sUSDe pre-depositors, 420 pool depositors and key companions. These will grant unique entry to early testnet and mainnet deployments, in addition to a number of gated buying and selling competitions – every of which can have a big prize pool together with SNX, stables and [redacted].

Factors shall be earned by pre-deposits, buying and selling efficiency on testnet and mainnet, referrals and different actions within the lead as much as the total deployment of Synthetix perps on Ethereum Mainnet.

Section 0 will begin this month, with sUSD and sUSDe deposit contracts reside earlier than ETH CC.

Mainnet Perp Summer season.

Restoring the position of SNX and sUSD

The SNX token is reclaiming its place on the coronary heart of Synthetix as a supply of yield, liquidity, and governance alignment. We’ve overhauled SNX staking to be intuitive: stake SNX, earn protocol charges. No PhD required. The staking providing is straightforward, without having for hedging, lively debt administration, or complicated onboarding.

Synthetix has the third longest dwelling stablecoin, sUSD. Whereas we have been inadvertently eradicating the utility of our personal stablecoin by launching v3, different protocols had seen the chance and have been launching their very own stablecoins. Now we have seen the error of our methods, and are restoring the utility of sUSD.

Stakers now not mint sUSD, that position now sits with the Treasury Market, which dynamically mints, burns and deploys sUSD to keep up the peg and gas buying and selling liquidity within the orderbook. sUSD would be the deposit asset for AMMs to market-make on the trade, producing yield from buying and selling exercise, from sharing charges and from liquidations.

Synthetix has been a DeFi pioneer since its inception. With >50% of SNX now staked, Treasury-funded buybacks, and a Mainnet launch on the horizon, SNX is poised for a renewed position in DeFi.

Conclusion

The nice irony of the L2 scaling roadmap is that it has made house for innovation and DeFi to return to L1, the place all of it started. Consideration is rightfully returning to Ethereum Mainnet and the protocols that add worth to the chain that began all of it. Synthetix is delivering a vital lacking piece: a high-performance perp trade, cementing Ethereum’s position as the house of world finance.

Comply with Synthetix carefully as we speedrun to mainnet:
