Bridge-Free Cross-Chain Swaps and Their Security Trade-Offs
Summary
The document explains 1inch’s approach to swapping assets between Solana and EVM-compatible networks without relying on conventional bridges. It describes Fusion+ as combining Dutch auction settlement with cryptographically secured escrow contracts, linking assets across chains for trustless execution. The stated aims include reducing exposure to bridge vulnerabilities, protecting transactions from front-running and sandwich attacks, and limiting liquidity fragmentation by keeping liquidity in native pools. Developer access through an API is also mentioned.
The article cites support for Solana and more than a dozen EVM-compatible networks, and claims the service can reach a large set of Solana tokens at low cost. These are product claims rather than comparative measurements: no independent security audit, execution data, or slippage analysis is provided. The architecture may reduce reliance on bridge infrastructure, but the document does not establish that all cross-chain risks disappear. It notes regulatory uncertainty and names other interoperability systems, without evaluating their relative performance.
Key ideas
- Fusion+ is described as combining Dutch auctions and cryptographic escrow for cross-chain swaps.
- Avoiding conventional bridges is intended to reduce exposure to bridge-specific vulnerabilities.
- The system includes MEV protection intended to limit front-running and sandwich attacks.
- Direct swaps are presented as a way to reduce liquidity fragmentation and slippage.
- The document gives no independent security or performance comparison across interoperability systems.
