with Fusion+ API
What is Fusion+

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.
