These improvements ensure that 1inch remains at the forefront of DeFi innovation, offering users the best possible conditions for every swap.
Pathfinder: Smarter Routing, Better Rates
At the heart of 1inch v2 lies Pathfinder, an advanced algorithm that goes beyond simple multi-source routing. Unlike traditional aggregators that split trades across different protocols, Pathfinder takes it a step further by analyzing multiple market depths within the same protocol.
This means that even within a single exchange like Uniswap or Curve, the algorithm can identify optimal price tiers and use them as intermediate bridges between tokens. By combining inter- and intra-protocol routing, Pathfinder constructs highly efficient swap paths that traditional methods simply can’t match.
For example, when swapping sBTC for sUSD, 1inch v2 delivers rates nearly 98% better than Uniswap alone—thanks to its ability to navigate complex liquidity layers and account for gas costs in real time.
This level of sophistication allows users to access deeper liquidity pools, avoid slippage, and achieve maximum output on every trade.
Redesigned UI: Simplicity Meets Flexibility
User feedback played a crucial role in shaping the new interface. Built from the ground up, the 1inch v2 UI prioritizes clarity, responsiveness, and customization.
Key enhancements include:
- A clean, modular layout where users can toggle between core functions
- A real-time USD value display showing total return and gas cost in fiat
- Integrated price charts for selected token pairs
- A comparison module that lets users evaluate routes side-by-side
The modular design allows traders to tailor their workspace—whether they want a minimalist swap interface or a full dashboard with analytics. Everything is designed to reduce cognitive load and streamline decision-making.

Unmatched Speed and Performance
Speed is critical in DeFi, where market conditions change in milliseconds. 1inch v2 delivers the fastest response times in the industry for comparable complexity levels:
- Quote generation: Reduced from 6 seconds to just 0.4 seconds
- Page load time: Down from 5 seconds to 1 second
- API response time: Also improved to 0.4 seconds
These performance gains aren’t just cosmetic—they translate into real-world advantages. Faster quotes mean users can act on opportunities before prices shift. Quick page loads enhance accessibility, especially on mobile devices or low-bandwidth connections.
Under the hood, this speed is made possible by optimized backend architecture and a rebuilt aggregation proxy contract that handles complex multi-route transactions with minimal latency.
Broad Protocol Support and Future Expansion
1inch v2 integrates with all major DeFi protocols, ensuring comprehensive liquidity coverage:
- DEXs: Uniswap (v1/v2), SushiSwap, Curve, Balancer, Kyber, DODO
- Lending Platforms: Aave, Compound
- Yield Aggregators: Yearn, C.R.E.A.M., Swerve
- Specialized Exchanges: Shell, BlackholeSwap, Value Liquid
Additionally, support for private market makers is in development, which will further expand liquidity sources and improve price discovery.
This wide integration ensures that users always have access to the deepest available pools—no matter which tokens they’re trading.
Collateral Token Management Made Easy
One of the standout features of 1inch v2 is its ability to handle collateral tokens from lending platforms like Aave and Compound directly within the swap flow.
Previously, users had to manually navigate to Aave or Compound to wrap (e.g., turn DAI into cDAI) or unwrap assets—a process requiring multiple transactions and extra gas fees.
Now, 1inch automates this process. Users can:
- Pack tokens into collateral (e.g., DAI → cDAI)
- Unpack collateral back into base tokens (cUSDC → USDC)
- Migrate positions between pools—all within a single transaction
This integration not only saves time but also reduces costs significantly, especially during volatile markets when gas prices spike.
Reducing Failed Transactions with Dynamic Fills
Failed transactions are a common pain point in DeFi—often caused by sudden price changes or liquidity shifts. 1inch v2 tackles this with its partial and dynamic fill mechanism.
Here’s how it works:
- If part of a multi-route swap fails (e.g., Uniswap rate changes), that leg is canceled.
- The unswapped portion is automatically redirected to alternative routes (e.g., SushiSwap or Curve).
- As long as the final rate stays within acceptable slippage bounds, the transaction completes successfully.
Instead of a full rollback, users receive partial execution—ensuring they never lose gas fees on entirely failed swaps.
This resilience makes 1inch v2 one of the most reliable aggregation tools in high-volatility environments.
Gas Optimization: Maximum Savings
Every swap on 1inch v2 is optimized for gas efficiency:
- Direct swaps (e.g., on Uniswap) now have near-zero aggregation overhead
- Complex multi-path trades are streamlined using compressed calldata and efficient contract logic
- Users can choose between "Maximum return" (best rate) and "Lowest gas" (cheapest fee) modes based on their priorities
These optimizations mean lower costs per transaction—especially valuable during network congestion.
Security You Can Trust
Security is non-negotiable in DeFi. The 1inch v2 smart contract has undergone five independent audits by leading firms:
- Certik
- Hacken
- Scott Bigelow
- MixBytes
- Chainsulting
Additional audits from OpenZeppelin, Consensys Diligence, SlowMist, Haechi Labs, and Coinfabrik are pending completion—further reinforcing confidence in the protocol’s integrity.
