Quick Launch
Ultra Swap API
RPC-less architecture and Jupiter handles all trading optimizations for you.
Plugin
Easiest way to integrate full end-to-end Ultra Swap interface.
Features
Juno Liquidity Engine
Juno Liquidity Engine
Ultra Swap utilizes the latest Juno Liquidity Engine which aggregates across multiple liquidity sources, including Jupiter’s proprietary routing engines both Metis and Jupiter Z (RFQ), and third-party liquidity sources, for the best possible price. It also includes self-learning capabilities (to detect and sideline low-quality liquidity sources) which creates a competitive environment for all liquidity sources to continously optimize their performance and price.
Transaction Sending
Transaction Sending
Over the years of experiment and development, we have optimized and continues to better our transaction sending service. Using various strategies involving multiple RPCs, priority fees/Jito tips estimation, and more, we are able to send transactions at a blazing fast speed with a high success rate (while still being MEV-protected).
95% of all swaps are executed under 2 seconds via our proprietary transaction sending engine.For more information on latencies, refer to the latency section.
MEV Protection
MEV Protection
According to both our internal monitoring system and external resources such as Sandwiched.me, Ultra has the lowest incidence of MEV attacks across all existing applications, by far. Comparing using the ratio of volume to the amount of value extracted, Ultra Swap has the highest volume yet the lowest value extracted.
Real Time Slippage Estimator
Real Time Slippage Estimator
Building on top of our previous versions of slippage estimation/optimization engines, we have developed a new Real Time Slippage Estimator (RTSE), that is able to intelligently estimate the best possible slippage to use at the time of execution, balancing between trade success and price protection. RTSE uses a variety of heuristics, algorithms and monitoring to ensure the best user experience:
- Heuristics: Token categories, historical and real-time slippage data, and more.
- Algorithms: Exponential Moving Average (EMA) on slippage data, and more.
- Monitoring: Real-time monitoring of failure rates to ensure reactiveness to increase slippage when necessary.
Gasless
Gasless
Ultra Swap provides different gasless mechanisms for different scenarios.
- Gasless via Jupiter Z (RFQ): All swaps routed via Jupiter Z are gasless, as the market maker is the fee payer for the transaction.
- Gasless via Gasless Support: Depending on the tokens and trade sizes of your swap, Ultra Swap will automatically determine if it can provide gasless support to your swap by helping you pay for the transaction fee of your swap - you can identify this via the secondary signer in the transaction.

What About Legacy Swap API?
Ultra Swap API is the next evolution of our swap infrastructure, designed and continuously optimized to deliver the best possible trading experience on Solana. We are focused on providing a high-performance, reliable, and feature-rich API that incorporates the latest advancements and optimizations for users and integrators. While Ultra Swap API is engineered for optimal performance and ease of integration, the Legacy Swap API remains available for developers who require advanced customization, such as:- Adding custom instructions.
- Incorporating Cross Program Invocation (CPI) calls.
- Selecting specific broadcasting strategies for signed transactions (e.g., priority fee, Jito, etc.).
- Choosing which DEXes or AMMs to route through.
- Modifying the number of accounts used in a transaction.
- RPC management: Retrieving wallet balances, broadcasting, and tracking transactions.
- Transaction fee selection: Managing priority fees, Jito fees, and more.
- Slippage optimization: Determining the best slippage settings for trade success and price protection.
- Transaction broadcasting: Ultra Swap leverages a proprietary transaction engine for superior speed and reliability.
- Swap result parsing: Handling transaction polling, parsing, and error management.
