Abstract
In the dynamic and fragmented landscape of decentralized finance (DeFi), achieving optimal trade execution across various decentralized exchanges (DEXs) presents a significant challenge. The Soroswap-Aggregator, proposed for development on the Soroban platform, aims to address this challenge by intelligently aggregating liquidity from multiple DEXs. This paper revisits the conceptual underpinnings and developmental strategies for the Soroswap-Aggregator smart contract. It emphasizes an optimization algorithm designed to minimize slippage and gas costs while maximizing trade efficiency. Through a blend of technical rigor and strategic foresight, this investigation outlines the functions, optimization processes, and key considerations essential for the smart contract’s successful implementation.1. Introduction
Amidst the burgeoning DeFi ecosystem, the dispersion of liquidity across numerous DEXs complicates the pursuit of efficient trade execution. The Soroswap-Aggregator concept harnesses the Soroban platform’s capabilities to consolidate this liquidity, facilitating superior trade outcomes. By navigating the complexities of variable gas fees, DEX transaction fees, slippage, and liquidity depth, the aggregator seeks to offer a solution that optimizes swaps for end-users.2. System Architecture and Core Functions
2.1 The Swap Function: A Closer Look
Central to the Soroswap-Aggregator is theswap function, designed with the following parameters for a user-centric trading experience:
fromTokenanddestToken: Specifies the trading pair for the swap.amount: The volume offromTokento be exchanged.amount_out_min: Ensures the trade is executed only if the return indestTokenmeets or exceeds this threshold, guarding against undesirable slippage.distribution: A strategic array dictating the apportionment of the trade across selected DEXs for optimal execution.
2.2 Optimizing Trade Execution
The underlying optimization algorithm is tasked with generating thedistribution array. This process entails a comprehensive analysis incorporating:
- Gas Costs and DEX Fees: Balancing the trade-off between transaction fees and optimal execution paths.
- Slippage Mitigation: Estimating and minimizing the price impact of trades across various liquidity depths.
- Liquidity Analysis: Assessing available liquidity to ensure the aggregator routes trades through the most efficient DEXs.
