Router v5 represents 1inch's most significant gas optimization breakthrough, delivering up to 32% efficiency gains compared to competitors while maintaining the security standards that have made it the leading DEX aggregator. Released in November 2022, this technical upgrade fundamentally changed how traders access optimal swap routes across decentralized finance.
The improvements deliver tangible cost savings for traders. A 1,000 ETH swap into DAI through DODO and Curve pools demonstrates 3% better gas efficiency than Router v4, 14% better than the closest competitor, and 32% more efficient than other market offerings. These gains compound significantly for high-volume traders who execute multiple daily transactions.
Router v5 achieves 5% better gas efficiency than v4 and 10% better efficiency compared to the second-best DEX aggregator, establishing 1inch's technical leadership in the competitive DEX space.
Technical Architecture Behind the Efficiency Gains
Integration with Limit Order Protocol v3
Router v5 merged with the 1inch Limit Order Protocol v3, facilitating more efficient swaps and cheaper gas while allowing users to take full advantage of the protocol that grew to capture about 40% of the DEX market. This integration eliminated redundant smart contract calls and streamlined the execution path for both market orders and limit orders.
The merger creates synergies between 1inch's aggregation technology and its limit order infrastructure. Traders can now access both instant market swaps and patient limit orders through a unified interface, reducing the complexity and gas costs associated with managing separate protocols.
New Interaction Logic and Error Handling
Router v5 introduces sophisticated interaction logic with pre- and post-interactions that optimize transaction execution. Custom errors were added to facilitate a convenient and gas-efficient way to explain to users why specific operations failed, replacing generic error messages that consumed unnecessary gas.
These improvements reduce failed transaction costs and provide clearer feedback for debugging issues. When a swap fails due to slippage or insufficient liquidity, the custom error system immediately identifies the problem without wasting gas on expensive revert operations.
Real-World Performance Improvements
Comprehensive Gas Efficiency Testing
1inch conducted extensive testing across multiple scenarios to demonstrate Router v5's improvements:
| Swap Details | v4 vs v5 Improvement | vs Best Competitor | vs Other DEXs |
|---|---|---|---|
| 100,000 USDC → USDT (Uniswap v3) | 4% more efficient | 8% more efficient | 24% more efficient |
| 50 ETH → USDC (Balancer) | 6% more efficient | 14% more efficient | 26% more efficient |
| 100 ETH → USDT (Two Uniswap pools) | 5% more efficient | 8% more efficient | 24% more efficient |
| 1,000 ETH → DAI (DODO + Curve) | 3% more efficient | 14% more efficient | 32% more efficient |
These performance improvements make Router v5 consistently more gas efficient across different trade sizes and liquidity sources, demonstrating the upgrade's broad applicability rather than optimization for specific scenarios.
Cost Savings for Different Trading Patterns
The efficiency gains scale differently based on trading patterns. Large trades benefit most from the multi-pool routing optimizations, while smaller trades see the biggest improvements from reduced overhead costs and streamlined error handling.
High-frequency traders executing dozens of daily swaps can reduce their monthly gas costs by 10-15% compared to the previous version, and significantly more compared to using other DEX aggregators. These savings often exceed the difference in trading fees between platforms.
Security and Audit Process
Router v5 has been thoroughly audited by almost a dozen of the industry's most reputed projects, including Consensys, OpenZeppelin and ABDK Consulting. The comprehensive security review process took months to complete, with particular focus on the new interaction logic and limit order protocol integration.
The Consensys audit alone involved 40 person-days of review work, examining every aspect of the Router v5 codebase for potential vulnerabilities. This rigorous security process ensures that the gas optimizations don't compromise user fund safety or introduce attack vectors.
Beyond formal audits, 1inch maintains an active bug bounty program specifically for Router v5, rewarding security researchers who identify vulnerabilities in the new system. This ongoing security monitoring helps maintain the router's integrity as trading volumes and complexity increase.
How Router v5 Impacts Different Trading Strategies
Arbitrage Trading Benefits
Arbitrage traders benefit significantly from Router v5's efficiency improvements because their profits depend on minimizing execution costs. The 5-32% gas savings can determine whether arbitrage opportunities remain profitable after accounting for gas fees, especially during network congestion periods.
Professional arbitrage operations executing hundreds of daily trades see substantial monthly cost reductions. The improved error handling also reduces failed transaction costs, which can be particularly expensive when attempting time-sensitive arbitrage during volatile market conditions.
DeFi Trading Strategy Optimization
For traders implementing complex DeFi strategies that require multiple token swaps, Router v5's efficiency gains compound across each transaction. Yield farming strategies that involve regular rebalancing can reduce their operational costs significantly.
The integration with Limit Order Protocol v3 also enables more sophisticated strategies combining immediate swaps with pending limit orders, allowing traders to optimize their entry and exit timing while maintaining cost efficiency.

The Future of DEX Optimization
Router v5 establishes a new benchmark for DEX aggregator efficiency, but 1inch continues developing further optimizations. The success of the limit order protocol integration suggests future versions may incorporate additional protocols and advanced routing algorithms.
Co-founder Sergej Kunz noted that users now save at least 8-14% more than using any other DeFi product, as reported by Cointelegraph, but the team continues accumulating improvements for future router versions. The competitive pressure from other DEX aggregators ensures continued innovation in gas optimization.
