The pace of innovation in decentralized finance (DeFi) over the past few years has been nothing short of extraordinary. As we reflect on the journey of one of DeFi’s pioneering protocols, Synthetix stands out not only for its technical ambition but also for its evolution from a small, centralized team into a fully decentralized ecosystem driven by community governance.
This year-end review by Synthetix founder Kain offers a rare insider’s perspective on how much has changed in just 12 months—and what lies ahead as the protocol prepares for its next major leap.
A World Transformed: From 2019 to 2025
Rewind to December 31, 2019. At that moment, Synthetix was still operating under a “benevolent dictator” model, with the Synthetix Foundation overseeing development. The team? Less than ten people. The roadmap? Uncertain. The infrastructure? Primitive by today’s standards.
Back then:
- Oracle systems were centralized.
- There was no Optimistic Ethereum—Layer 2 wasn’t even on the radar.
- Fee reclamation hadn’t launched.
- SNX liquidity was minimal, trading just millions daily across exchanges.
- No sUSD Curve pool existed.
- No grantsDAO, no Spartan Council.
- Kwenta was just a UX idea buried in a notebook.
Fast forward to 2025, and the transformation is staggering. Today, Synthetix powers hundreds of millions in synthetic assets, with sUSD exceeding $100 million in supply and total synthetics surpassing $250 million. The protocol has migrated to Layer 2, drastically reducing gas costs and eliminating front-running risks through advanced oracle designs.

Governance and Decentralization: Building the Future
One of the most significant shifts has been the rise of decentralized governance. In 2019, improvement proposals ended at SIP-34. By 2025, the community had advanced to SIP-103, with 67 SCCP (Synthetix Community Contract Parameters) changes implemented—compared to just nine previously.
The creation of protocolDAO, grantsDAO, and the Spartan Council marked turning points in decentralization. These bodies now manage funding, security audits, and strategic direction—proving that large-scale coordination without central control is not only possible but effective.
And let’s not forget xSNX—the tokenized staking derivative that unlocked new composability use cases. Paired with dHedge’s integration, it demonstrated Synthetix’s potential as a foundational layer for third-party financial products.
Technical Breakthroughs That Changed Everything
Several key upgrades laid the groundwork for today’s robust system:
1. Layer 2 Migration
Moving to Optimistic Ethereum solved critical pain points: high gas fees, slow settlement, and vulnerability to MEV (miner extractable value). With L2, trading became affordable and scalable—opening the door for retail participation.
2. Virtual Synths & Improved Incentives
By decoupling debt from direct collateral exposure via Virtual Synths, the protocol improved capital efficiency and reduced systemic risk. Combined with rebalancing incentives, this corrected the earlier issue of debt pool imbalances that plagued early 2020.
3. Expanded Collateral Options
In 2019, only SNX could be staked. Now, ETH and renBTC are accepted—diversifying risk and attracting broader participation. This multi-collateral approach strengthens resilience and aligns with broader DeFi trends.
4. Enhanced User Experience
Features like limit orders, variable fees based on community consensus, and binary options (now spun off into independent projects) have significantly improved usability. Futures trading, once delayed due to oracle latency, now runs smoothly on L2 testnets and will launch mainnet soon.
The Road Ahead: Synthetix V3 and Billions in Scale
Looking ahead, the focus shifts decisively toward Synthetix V3—a complete contract rewrite designed to address lingering architectural limitations.
Key goals for V3 include:
- Modular design for easier upgrades
- Cross-chain compatibility
- Improved capital efficiency
- Enhanced risk management frameworks
- Support for complex derivatives beyond current offerings
This overhaul isn’t incremental—it’s foundational. The aim? To scale Synthetix to hundreds of billions in synthetic asset volume over the next 18 months.
With sufficient treasury reserves managed by synthetixDAO, funding isn’t a constraint. What matters now is execution speed and developer bandwidth. Expect contributor numbers to grow significantly throughout 2025 to meet these ambitious targets.

Why Synthetix Stands Out in DeFi
While competitors offer stablecoins or isolated derivatives, Synthetix has built something rarer: a unified platform for permissionless synthetic assets.
Unlike DAI—which now relies on over 50% centralized collateral—Synthetix maintains a stronger decentralization posture with fully on-chain backing. While DAI wins on total supply ($1B+), Synthetix wins on purity of design and resistance to off-chain dependencies.
Moreover, sBTC’s Curve pool remains one of the most liquid Bitcoin representations on Ethereum—driving adoption and bridging ecosystems.
Frequently Asked Questions (FAQ)
Q: What is Synthetix V3?
A: V3 is a full architectural redesign of the Synthetix protocol aimed at improving scalability, cross-chain functionality, and capital efficiency. It will serve as the foundation for expanding into multi-billion dollar markets.
Q: Can I stake SNX today?
A: Yes. Users can stake SNX to back synthetic assets and earn rewards through inflationary emissions and fee reclamation. The xSNX wrapper allows staked positions to be used in other DeFi protocols.
Q: How does Synthetix prevent front-running?
A: By operating on Optimistic Ethereum (Layer 2), transaction ordering is more predictable and less susceptible to MEV exploits common on Ethereum mainnet.
Q: Is sUSD decentralized?
A: Yes. sUSD is fully backed by crypto-collateral (SNX, ETH, renBTC) and governed by smart contracts without custodial control—making it one of the most decentralized stablecoins in existence.
Q: What are Synths?
A: Synths are ERC-20 tokens that track the value of real-world assets like USD, gold, stocks, or cryptocurrencies. They enable global, permissionless exposure without intermediaries.
Q: How can developers contribute?
A: Through grantsDAO and public repositories, developers can propose features, audit code, or build integrations using Synthetix’s open APIs and SDKs.

Final Thoughts: Confidence in the Future
The last few years have proven that building a decentralized derivatives exchange is incredibly complex—but also profoundly impactful. The stability seen over recent months shows the system works at scale.
As we enter 2025, momentum is building. With V3 on the horizon and an active, engaged community steering the ship, Synthetix is poised to become a cornerstone of the global DeFi stack.
For anyone watching the evolution of blockchain-based finance, Synthetix represents both a milestone achieved and a future unfolding.
