Overview

Understanding how the execution layer works.

SwapExecutor: The SwapExecutor provides a unified interface for executing swaps. It handles interactions with the underlying liquidity pools, manages token approvals, controls input/output amounts, and ensures gas-efficient and secure execution. Each protocol must implement its own SwapExecutor (a Solidity contract) tailored to its specific logic and requirements.

SwapEncoder: The SwapEncoder encodes protocol components and swap parameters into valid calldata for the corresponding SwapExecutor contract. It ensures that swap details—including input/output tokens, pool addresses, and other protocol-specific parameters—are accurately formatted and encoded before being sent to the SwapExecutor. Each protocol must implement its own SwapStructEncoder Python class to maintain compatibility with its SwapExecutor.
