Decentralized finance (DeFi) continues to evolve at a rapid pace, and innovation remains the key driver behind user adoption and platform sustainability. At the forefront of this transformation is 1inch, a leading DeFi aggregator known for its advanced routing algorithms and efficient trading solutions. The platform has just unveiled a significant technological upgrade that slashes transaction costs for both swaps and limit orders—delivering savings of up to 16% on gas fees.
This latest enhancement reinforces 1inch’s commitment to optimizing user experience, improving capital efficiency, and reducing barriers in the decentralized trading ecosystem.
“At 1inch, we believe in relentlessly pushing the boundaries of the DeFi world. Our latest upgrade shows our true commitment to innovation, efficiency, and user empowerment. We're not just optimizing transactions—we're pioneering a future where every swap and order is a step toward a more accessible and user-friendly DeFi ecosystem,” says Sergej Kunz, co-founder of 1inch. “We have the most optimized swap router and limit orders in the market. Our performance is at least 10% better than our closest competitor.”
Let’s explore how these upgrades translate into real-world benefits for traders, developers, and DeFi enthusiasts.
Optimized Swap Router for Maximum Efficiency
The 1inch Swap Router has long been recognized as one of the most sophisticated tools in DeFi, leveraging intelligent pathfinding across multiple liquidity sources to ensure users get the best possible rates. With this update, the team has fine-tuned the router’s core logic to reduce gas consumption across the most frequently used trading paths.
Key improvements include:
- Gas savings of up to 16% on common swap routes.
- Enhanced performance on major protocols such as Uniswap v2/v3 and Curve.
- Reduced computational overhead through streamlined contract interactions.
These optimizations mean users can now execute trades faster and cheaper—especially critical during periods of high network congestion or when dealing with smaller transaction amounts where gas costs previously made certain trades economically unviable.

Unified Order Structure: Simplicity Meets Scalability
One of the most impactful changes in this release is the introduction of a unified order structure within the 1inch Limit Order Protocol. Previously, traditional limit orders and RFQ (Request for Quote) orders operated under separate frameworks. Now, they are integrated into a single, cohesive protocol architecture.
Benefits of the unified system:
- 14% improvement in gas efficiency for standard limit orders.
- 3% reduction in gas costs for RFQ-style orders.
- A lightweight design that supports future expansion of features like 1inch Fusion and advanced quoting mechanisms.
- Greater flexibility for integrators building on top of the protocol.
This consolidation not only simplifies development but also reduces maintenance complexity, paving the way for faster innovation and broader adoption across wallets, dApps, and trading platforms.
Developers interested in exploring the technical details can access the open-source implementation on GitHub or review comprehensive documentation covering protocol mechanics and integration guidelines.
Full Support for Permit2: Fewer Approvals, Better Security
Security and usability often sit at opposite ends of the spectrum in DeFi—but not anymore. The upgraded 1inch protocols now offer full support for Permit2, a universal token approval standard developed by Uniswap Labs.
What does this mean for users?
- No more repetitive token approvals: If you've already approved a token in another compatible DeFi application, you can trade it directly on 1inch without re-approving.
- Enhanced security posture: By minimizing the number of active approvals, users reduce their exposure to potential smart contract exploits or malicious frontends.
- Smoother user experience: Fewer transaction steps mean faster trades and lower friction—especially beneficial for frequent traders.
Permit2 represents a major leap forward in wallet interoperability and user control. With 1inch embracing this standard, users gain both convenience and peace of mind.
What’s Next? The Road to 1inch Fusion
While this upgrade marks a major milestone, it's only part of a broader vision. The 1inch team has confirmed that an upcoming enhancement to 1inch Fusion—its advanced order settlement layer—is set to roll out soon. This next phase will further boost execution quality by enabling deeper liquidity aggregation and MEV-resistant trade routing.
For traders and developers alike, staying ahead means leveraging platforms that continuously innovate. 1inch isn't just reacting to market demands—it's shaping them.
Frequently Asked Questions (FAQ)
Q: How much can I save on gas fees with the new 1inch upgrade?
A: Depending on the trade path and protocol used, users can save up to 16% on gas costs for swaps and up to 14% for limit orders, making small or frequent trades significantly more cost-effective.
Q: Do I need to do anything to benefit from Permit2 support?
A: No action is required. If you’ve previously approved a token in a Permit2-compatible app, you’ll automatically skip redundant approval steps when trading on 1inch.
Q: Is the unified limit order protocol available on all blockchains?
A: The upgraded protocol is being deployed across all networks where 1inch operates, including Ethereum, Arbitrum, Polygon, Optimism, and others. Full rollout details are available in official documentation.
