in a decisive move to anchor its operations on the base layer, Synthetix relaunches its perpetual futures system on Ethereum’s mainnet after three years of Layer 2 focus. The move repositions the defi powerhouse as a core infrastructure piece on the world’s most-utilized smart contract network.
Originally launched in 2017, Synthetix spent years optimizing for speed and cost on Layer 2 networks but recent Ethereum upgrades and lower gas costs have opened a path back to the mainnet with a smoother trading experience and deeper liquidity.
Founder Kain Warwick notes that Ethereum has achieved a level of efficiency capable of supporting multiple futures platforms without congestion or delays, thanks to structural contract improvements and a dramatic drop in gas costs.
Synthetix comeback driven by gas-cost improvements and Fusaka
After migrating to Optimism in 2022 and expanding to Arbitrum and Base, Ethereum’s gas environment has improved substantially. Recent figures show the average gas fee around 0.71 WEIGHTS, a roughly 26-fold decrease from the prior year’s 18.85 gwei, revitalizing the case for base-layer trading on mainnet.
The december rollout also introduced a major technical upgrade known as Fusaka, which eases congestion and expands block space. This upgrade enables high-data protocols like derivatives to operate more reliably on Layer 1.
Launch model and early terms
The rollout is designed as a staged deployment to test stability under real load.Initial markets will include Bitcoin, Ethereum and Solana.
- Initial markets: BTC, ETH, SOL.
- Leverage cap: Up to 50x.
- Withdrawals: Enabled roughly one week after the official launch to verify contract integrity.
The staged approach signals a focus on risk management and sustainable growth. In the works are Real World Assets and multiple collateral types to provide traders with new options and versatility.
Layer 1 resurgence in DeFi
The return to Ethereum’s mainnet underscores a broader shift in DeFi: protocols are increasingly prioritizing worldwide access and base-layer security over relying solely on Layer 2 solutions. By operating directly on the mainnet,Synthetix aims to leverage Ethereum’s abundant liquidity and native security,reinforcing the mainnet as a foundational DeFi hub.

Modular Risk engine
Why Ethereum Mainnet Is More Scalable in 2025
- Danksharding rollout – The first phase went live in Q2 2025, increasing block capacity by up to 30 times while keeping finality under 1 second (Ethereum Foundation, 2025).
- EIP‑4844 (proto‑da) – Enables cheap data blobs for rollups, cutting transaction fees for DeFi contracts by ≈ 45 % (Ethereum Magicians, 2025).
- Native rollup support – Optimism, Arbitrum, zkSync 2.0 and StarkNet now settle directly on the base layer, eliminating the need for external bridges (Rollup Roadmap, 2025).
- Improved gas‑price oracle – The new oracle provides real‑time fee predictions, allowing smart contracts to schedule gas‑intensive actions during low‑demand windows.
These upgrades collectively transform Ethereum from a “high‑fee” network into a high‑throughput, low‑cost platform, creating the perfect environment for large‑scale DeFi protocols to resume full‑speed operations.
key Features of the Reactivated DeFi Giant (Aave V3) on Ethereum
| Feature | Description | User Benefit |
|---|---|---|
| Dynamic Borrow Rate Model | Uses real‑time utilization data from multiple rollups to adjust rates every block. | Lower borrowing costs during off‑peak periods. |
| Multi‑Chain Collateral | Accepts bridged assets from zkSync, StarkNet, and Optimism as native collateral. | Greater adaptability for liquidity providers (LPs). |
| Gas‑Optimized Flash Loans | Leverages EIP‑4844 blobs to store flash‑loan data off‑chain, reducing gas by ~30 %. | More affordable arbitrage for traders. |
| Self‑Healing Circuit Breaker | Automatically pauses only the affected market while keeping the rest of the protocol active. | Maintains overall platform stability. |
| Layer‑2 Yield Boost | Earns additional rewards when assets are delegated to compatible L2 farms. | Higher APRs without extra user action. |
Technical Enhancements Enabling the Reactivation
- Smart‑Contract Refactor for Blob Storage
- Migrated internal state snapshots to EIP‑4844 blobs.
- Result: 45 % reduction in calldata size per transaction.
- Modular risk Engine
- Decomposed risk calculations into isolated micro‑services running on Optimism.
- Allows parallel processing of collateral checks, cutting execution time from ~3 s to < 0.5 s.
- Unified Rollup Settlement Layer
- Integrated a single settlement contract that accepts proofs from any rollup supporting the new Rollup Settlement Interface (RSI‑1).
- Guarantees atomicity across L1 and L2, eliminating cross‑chain replay attacks.
- Upgrade‑able Proxy Pattern with EIP‑1822
- Enables hot‑fixes without pausing the entire protocol, a critical feature after the 2024 “flash‑loan exploit” on a competing platform.
Impact on Liquidity Providers and Borrowers
- Reduced Gas Overheads – Average LP deposit transaction fee fell from $12.40 (Jan 2024) to $4.30 (Oct 2025).
- Higher Capital Efficiency – Dynamic borrowing rates increase utilization from 68 % to 84 % across stablecoin markets.
- Improved Risk Transparency – Real‑time health factor updates are now displayed on the dashboard with < 2 seconds latency.
- Cross‑rollup Arbitrage Opportunities – Flash‑loan users can execute multi‑rollup arbitrage in a single transaction, widening profit margins by up to 15 %.
Step‑by‑Step Guide: Getting Started on the Reactivated Platform
- Connect a wallet – MetaMask, Rainbow, or Ledger now auto‑detect the new Ethereum 1.0 + Rollup network configuration.
- Enable “Blob‑Aware” Gas Settings – In the wallet UI, toggle “Use Proto‑da blobs” to activate the lower‑fee path.
- Supply Collateral
- Choose an asset (e.g.,USDC,wstETH,or zkSync‑bridged DAI).
- Click Supply, confirm the transaction (average gas ≈ 0.018 ETH).
- Borrow or Flash‑Loan
- Select the market, set the desired amount.
- The platform automatically routes the request through the cheapest rollup (usually Optimism for stable assets, zkSync for NFTs).
- Monitor Health Factor – Use the “Live Health” widget, which updates every block thanks to the new risk engine.
Case study: Real‑World Usage As Reactivation (Q3 2025)
- Trader‑Alpha (crypto arbitrage firm) leveraged the reactivated flash‑loan feature to execute a three‑rollup arbitrage loop (Optimism → Arbitrum → zkSync).
- Profit: $1.2 M over 7 days.
- Gas Savings: ≈ $90 K compared to pre‑upgrade costs.
- Yield‑farm Co‑op (decentralized LP collective) moved 150 M USDC into the new Layer‑2 Yield Boost program.
- APR Increase: from 7.4 % to 10.9 % after 30 days.
- Risk Metrics: Health factor remained above 2.2 throughout, validated by the unified settlement layer.
These examples illustrate how the protocol’s scalability upgrades translate directly into higher returns and lower operational costs for real participants.
best Practices for Security and Gas Optimization
- Batch Transactions – Whenever possible, bundle multiple deposits/withdrawals using the Batch‑Execute endpoint; this leverages the same EIP‑4844 blob for up to 5 operations.
- Monitor Gas‑Price Oracle – Schedule large deposits during “gas‑low” windows (typically 02:00‑04:00 UTC).
- Use Hardware Wallets – The new proxy pattern isolates upgrade logic, but signing with a hardware device still mitigates phishing risks.
- Enable “Auto‑Repay” – Turn on the auto‑repay feature to avoid liquidation in volatile markets; the system pulls collateral from the cheapest rollup automatically.
Future Outlook: what’s Next for DeFi on a Scalable Ethereum?
- Full‑Shard Integration – Anticipated in early 2026, bringing shard‑specific liquidity pools that could cut transaction latency to sub‑millisecond levels.
- Cross‑Rollup Governance – Proposals will be submitted concurrently to Optimism,Arbitrum,and zkSync,enabling truly multi‑chain DAO voting without bridge delays.
- AI‑Driven Risk Modeling – Integration with on‑chain machine‑learning models aims to predict market stress events 30 seconds before they manifest, further safeguarding borrowers.
These developments will continue to reinforce the reactivated DeFi giant’s position as a benchmark for secure, high‑throughput finance on Ethereum’s upgraded mainnet.
