Integrate trustless cross-chain swaps
with Fusion+ API
What is Fusion+
Fusion+ is an upgraded version of 1inch's intent-based swap solution, featuring breakthrough functionality for cross-chain swaps. Competition between independent market makers (resolvers) and a unique order execution system make cross-chain swaps through Fusion+ highly efficient and secure, while maintaining self-custody.
Gasless transactions
Users sign an off-chain order without paying gas in native network tokens. All applicable network fees are covered by resolvers.
MEV protection by design
Fusion+ swaps are protected from MEV by the most advanced measures implemented by professional market makers.
Complete self-custody
Cross-chain swaps through Fusion+ remain trustless and self-custodial while still being efficient and secure.
Smart order execution
Fusion+ orders are executed using a unique algorithm that combines the Dutch auction approach with a dynamic price curve that adapts to gas prices.
Security compliance
All resolvers undergo KYC/KYB checks, and their liquidity is automatically scanned to detect and mitigate the risk of illicit activity.
Fast response time
The Fusion+ API delivers rapid response times, making it one of the fastest offerings on the market.
