We are thrilled to unveil 1inch v2, the next-generation decentralized finance (DeFi) aggregation protocol. With Pathfinder, an intelligent routing algorithm, and a revamped user interface (UI), this upgrade delivers unbeatable swap rates, lightning-fast response times, and enhanced transaction reliability.
Key Highlights
- Multi-protocol swaps: Distributes trades across 21+ liquidity sources, optimizing rates by leveraging different "market depths" within the same protocol.
- Intuitive UI: Simplified design for seamless trading, including real-time USD value tracking.
- Blazing speed: 0.4-second API response times—the fastest in DeFi.
- Comprehensive protocol support: Uniswap (v1/v2), Balancer, Curve, SushiSwap, Aave, Compound, and more.
- Collateral flexibility: Automatically pack, unpack, or migrate Aave/Compound collateral tokens during swaps.
- Reduced failures: Partial & dynamic fill mechanism minimizes transaction reversals.
Pathfinder: Smarter Routing for Better Rates
The heart of 1inch v2 is Pathfinder, an API-powered algorithm that:
- Discovers optimal routes across multiple protocols and market depths.
- Calculates gas costs to maximize net savings.
- Dynamically adjusts swaps if liquidity shifts mid-transaction.
👉 Discover how Pathfinder outperforms competitors
Example: For sBTC-sUSD swaps, 1inch v2 offers 98% better rates than Uniswap alone.
User Interface Upgrades
The completely redesigned UI prioritizes:
- Clarity: Real-time USD value tracking.
- Customization: Modular layout with price charts and comparison tables.
- Speed: 1-second page loads (5x faster than v1).
Unmatched Speed
1inch v2 slashes delays:
| Metric | v1 Time | v2 Time | Improvement |
|-----------------|---------|---------|-------------|
| Quote response | 6 sec | 0.4 sec | 15x |
| Page load | 5 sec | 1 sec | 5x |
Supported Protocols
1inch v2 integrates all major DeFi platforms, including:
- DEXs: Uniswap, Balancer, Curve, SushiSwap.
- Lending: Aave, Compound, Yearn.
- Private market makers (coming soon).
Collateral Token Swapping
No more manual repacking! 1inch v2 automatically:
- Converts cUSD/cTokens to underlying assets.
- Migrates collateral between Aave/Compound pools.
Partial & Dynamic Fill Mechanism
This innovation reduces failed transactions by:
- Cancelling unusable routes (e.g., if Uniswap liquidity drops).
- Redirecting funds to valid protocols mid-swap.
Gas Optimization
The new smart contract minimizes costs:
- Near-zero overhead for direct swaps (e.g., Uniswap).
- Efficient multi-path routing for complex trades.
Swap Modes
Choose your strategy:
- Maximum Return: Best rates (uses complex routes).
- Lowest Gas: Market-rate swaps (simplest path).
Security Audits
1inch v2 passed 5 independent audits by:
- CertiK
- Hacken
- MixBytes
- Chainsulting
- Scott Bigelow
Additional audits from OpenZeppelin and Consensys Diligence pending.
Conclusion
1inch v2 delivers:
✅ Best rates via Pathfinder.
✅ Instant swaps with 0.4-second responses.
✅ Fewer failures with dynamic fills.
