Gas-Free Swaps

Gas-Free Swaps allow users to execute trades without incurring gas fees or risk of front-running. This mechanism functions as a limit order with a variable exchange rate, filled by third-party resolvers. The exchange rate decreases over time in a Dutch auction style until it becomes profitable for resolvers to fill the order. Resolvers compete to fill these orders efficiently, often leveraging gas savings from batch processing, ensuring users receive favorable rates and minimizing price impact.

Limit Orders

Limit orders allow users to specify the exact price at which they want to buy or sell an asset. These orders can be highly customized with features such as partial fills, predicates for conditional execution, single and batch cancellations, and validation checks. Users place limit orders by simple on-chain signature and can be filled when conditions are met. This flexibility and efficiency make limit orders a powerful tool for precise trade management, allowing users to implement various trading strategies effectively.
