Contracts

xSwap has revolutionized the DeFi space with its unified smart contract repository, integrating all components of its Automated Market Maker (AMM) system into a single, accessible location. This approach not only simplifies the development process but also ensures a cohesive and streamlined interaction for developers looking to build on or integrate with the xSwap platform.

Core Contracts: The Foundation

The core of xSwap's smart contract architecture features the essential elements of the protocol:

• Factory Contract: Central to xSwap's operation, the factory contract initiates the creation of pair contracts for each unique token combination. It's designed with a focus on system integrity, facilitating the initiation of the protocol's trading charges to offer competitive rewards for liquidity providers.

• Pair Contracts: These contracts act as automated market makers, managing the reserves of token pairs to enable seamless swaps. They play a pivotal role in maintaining liquidity and are integral to the platform's functionality, also supplying data critical for decentralized oracle operations.

Unified Repository: A Developer's Hub

Recognizing the importance of developer accessibility and efficiency, xSwap consolidates its core functionality within a single repository. This centralization:

• Facilitates Interaction: Developers can easily navigate and interact with xSwap's comprehensive suite of contracts, enhancing the development experience and reducing the learning curve.

• Ensures Consistency: Housing all contracts in one location ensures version consistency and simplifies updates, providing developers with the latest features and improvements without the need to juggle multiple repositories.

Enhanced User Interaction

While core contracts form the backbone of xSwap, the platform acknowledges the need for user-friendly interfaces:

• Router: This contract is the primary interface for users and front-end applications, supporting trading, liquidity management, and special transactions involving wrapped tokens to ensure a seamless user experience.

• Library: A toolkit offering a range of convenience functions for interacting with core contracts, from price calculations to data retrieval, designed to make developer interaction as straightforward as possible.

Key Design Decisions

xSwap's architecture is underpinned by several innovative design choices:

• Streamlined Token Transfers: By calculating token transfers based on balance changes, xSwap optimizes the efficiency of swaps and interactions, moving away from traditional transfer mechanisms.

• Wrapped Token Integration: To simplify interactions with native CrossFi tokens, xSwap utilizes wrapped tokens (WXFI), streamlining contract operations and enhancing ecosystem compatibility.

• Minimum Liquidity Thresholds: To address potential precision issues and establish a reliable liquidity baseline, xSwap implements a mechanism to burn the initial liquidity tokens, setting a foundational supply floor.
