The decentralized finance (DeFi) landscape is evolving rapidly, and innovation remains the cornerstone of user adoption and satisfaction. At the forefront of this transformation, 1inch has unveiled a significant technological upgrade that redefines efficiency in on-chain trading. With swaps and limit orders now up to 16% cheaper, this enhancement marks a pivotal advancement for traders, developers, and DeFi integrators alike.
This upgrade isn't just about minor optimizations—it's a comprehensive overhaul designed to reduce gas costs, streamline user experience, and reinforce security. By refining core components like the swap router, unifying order structures, and integrating advanced token permission systems, 1inch continues to solidify its position as a leader in efficient DeFi solutions.

Optimized Swap Router for Maximum Efficiency
At the heart of every DeFi transaction lies the swap router—the engine responsible for finding the most cost-effective path across liquidity sources. The 1inch swap router has long been recognized as the most optimized solution in the market, leveraging sophisticated aggregation algorithms to scan hundreds of pools across multiple protocols.
In this latest iteration, 1inch has pushed performance even further. The updated router reduces gas consumption by up to 16% on common trading routes, particularly those involving Uniswap v2/v3 and Curve Finance. This improvement translates directly into lower transaction fees for users, especially during periods of high network congestion when gas prices surge.
The optimization stems from smarter contract execution paths and reduced bytecode overhead. For frequent traders and automated strategies, these savings accumulate quickly, making 1inch an even more attractive choice for cost-sensitive operations.
Such advancements are not only beneficial for individual users but also critical for DeFi integrators—dApps, wallets, and platforms building on top of 1inch’s API—who can now offer their users superior pricing and execution reliability.
Unified Order Structure: Merging Limit and RFQ Orders
One of the most impactful changes in this upgrade is the complete redesign of the 1inch Limit Order Protocol. Previously, limit orders and RFQ (Request for Quote) orders operated under separate frameworks. Now, they’ve been unified into a single, streamlined protocol architecture.
This new structure brings several key benefits:
- Improved gas efficiency: Upgraded limit orders are now 14% more gas-efficient, while RFQ-style orders see a 3% reduction in gas usage.
- Enhanced extensibility: The unified system supports future innovations such as 1inch Fusion, a privacy-preserving trading mechanism that prevents front-running.
- Simplified development: Developers benefit from a consistent interface, reducing integration complexity and maintenance overhead.
By merging these two order types, 1inch enables greater flexibility without sacrificing performance. Traders can set precise price targets with limit orders while still accessing high-liquidity quotes through RFQ mechanisms—all within one cohesive system.
For advanced users and algorithmic traders, this means faster execution, tighter spreads, and reduced slippage. It also opens the door for more sophisticated trading strategies that combine conditional logic with real-time quote fetching.
Full Support for Permit2: Streamlined Approvals, Enhanced Security
A persistent friction point in DeFi has always been token approvals. Every time a user wants to trade a new token on a new platform, they must submit an approval transaction—a process that consumes gas and increases exposure to potential exploits if permissions are mismanaged.
Enter Permit2, a universal token approval standard developed by Uniswap Labs. The upgraded 1inch protocols now offer full native support for Permit2, eliminating redundant approval steps and improving overall security.
Here’s how it works:
If a user has already approved a token for use in another DeFi application that supports Permit2, they can trade it on 1inch without needing to re-approve. This cross-protocol compatibility drastically simplifies the trading flow.
More importantly, Permit2 enhances security by allowing time-limited and amount-capped allowances, reducing the risk associated with infinite token approvals. With fewer open permissions floating around the blockchain, users face a smaller attack surface—making their wallets safer by design.

What This Means for DeFi Users and Builders
These upgrades collectively represent more than just technical improvements—they signal a shift toward a more accessible, efficient, and secure DeFi ecosystem.
For end users:
- Lower costs mean better returns on every trade.
- Fewer approval steps lead to smoother onboarding.
- Increased reliability builds trust in decentralized tools.
For developers and dApp builders:
- Access to the most optimized routing logic enhances product competitiveness.
- Unified APIs simplify integration efforts.
- Cutting-edge features like Fusion and Permit2 support future-proof their applications.
As Sergej Kunz, co-founder of 1inch, puts it:
“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 towards a more accessible and user-friendly DeFi ecosystem.”
He adds: “We have the most optimized swap router and limit orders in the market. Our performance is at least 10% better than our closest competitor.”
Frequently Asked Questions (FAQ)
