xSwap is the next evolution in decentralized trading on the CrossFi Chain. Built on advanced smart contract technology and powered by the constant product formula, xSwap operates as an automated market maker (AMM) designed for efficient, secure, and censorship-resistant token swaps. This protocol represents a direct advancement from existing AMM models by enhancing liquidity provision rewards, maintaining competitive and user-friendly trading fees, and fostering a fully decentralized environment open for community contribution and scrutiny.
At its core, xSwap enables users to swap tokens—including the algorithmic stablecoin xUSD—while also allowing participation in liquidity pools, strategic token bonding powered by the ApeBond SDK, and, soon, yield farming by staking liquidity provider tokens. This versatile functionality situates xSwap as a key component of the broader CrossFi ecosystem, seamlessly connecting liquidity providers, traders, and developers.
xSwap unifies several key functions that together create a robust decentralized exchange environment. Each main function is described below:
xSwap’s swap functionality enables users to exchange ERC‑20 tokens (including xUSD) quickly and transparently. Trades are executed via smart contracts using the constant product formula (x × y = k), which dynamically adjusts prices based on liquidity reserves. This design ensures fair market rates, minimal slippage, and efficient on-chain execution—without relying on centralized order books.
All swaps are non-custodial and executed atomically, meaning tokens never leave the user’s control until the transaction is finalized. This architecture enhances security and ensures predictable outcomes. The low, fixed trading fee (approximately 1%) is split between liquidity providers and protocol operations, promoting a sustainable fee model while maintaining trader-friendly conditions.
Liquidity pools are fundamental to the xSwap ecosystem. They allow users to contribute pairs of tokens (e.g., xUSD–ETH) and receive LP tokens representing their share. These LP tokens entitle holders to a portion of the fees generated by the pool, which are automatically compounded to increase the value of their position over time.
xSwap's liquidity architecture uses pair contracts that continuously update internal token balances and pricing. This setup ensures swap pricing remains accurate, even under high-volume activity. Additionally, users can freely add or remove liquidity at any time, offering flexibility and aligning with the decentralized ethos of the CrossFi Chain.
xSwap’s Bond feature, integrated through the ApeBond SDK, introduces a sophisticated financial tool that enables users to acquire native CrossFi ecosystem tokens at discounted prices. Participants deposit select assets—such as xUSD or other approved ERC-20 tokens—and receive discounted token allocations with a predefined vesting schedule.
Bond positions are issued as transferable NFTs conforming to the ERC-5725 standard, which allows users to flexibly manage their bonded assets or transfer their vesting rights to other participants. This adds both liquidity and composability to bonded positions, making them compatible with a broader set of DeFi strategies.
The Bond mechanism not only facilitates strategic portfolio rebalancing but also provides users with a lower cost basis, making it an ideal tool during volatile market phases. By supporting on-chain, trustless, and transparent participation in token distribution, the Bond feature helps decentralize token ownership and strengthen the capital foundation of the CrossFi ecosystem.

The upcoming Farm feature will enable LP token holders to stake their positions and earn additional rewards. Yield farming complements the fee-based returns from swaps by distributing bonus incentives—often in the form of CrossFi-native tokens or ecosystem-partner rewards.
Farms will be configurable based on pool-specific parameters such as allocation points, lock durations, and reward rates. By introducing time-based incentives, the farming mechanism encourages longer-term liquidity stability, thereby improving swap efficiency and token price resilience. Farms will be fully transparent, on-chain, and governed through decentralized parameters once live.
xSwap’s strength comes from its inclusive and synergistic ecosystem design, which engages a wide spectrum of participants—each playing a distinct role in the growth and sustainability of the CrossFi Chain.
Liquidity Providers
Individuals, institutions, and token project teams supply liquidity to trading pools, earning a share of transaction fees and, in the future, farming rewards. Their contributions deepen liquidity, reduce slippage, and enhance market efficiency across the platform.
Traders
Casual users, arbitrageurs, and DApps benefit from instant token swaps with transparent pricing and minimal slippage. The combination of low fees, decentralized execution, and consistent liquidity makes xSwap a reliable foundation for everyday trading activity on the CrossFi Chain.
Strategic Bonders
Through the Bond mechanism, users can acquire ecosystem tokens at discounted rates with programmable vesting. This attracts longer-term investors, promotes sustainable token distribution, and provides a capital-efficient way to participate in CrossFi’s growth.
Developers and Builders
xSwap’s modular, open-source smart contracts and comprehensive API toolkit empower developers to integrate swap, pool, and bond functionalities into their own DApps. This extensibility fosters the creation of new financial primitives and reinforces CrossFi as a developer-friendly chain for building next-generation DeFi tools.
Together, these groups form a dynamic and self-reinforcing network that drives xSwap’s liquidity, adoption, and innovation. Their combined activity increases Total Value Locked (TVL), improves token utility, and strengthens CrossFi’s position as a decentralized financial infrastructure layer.
xSwap is architected around a modular, upgradeable smart contract system optimized for performance, scalability, and developer extensibility.
Router Contract:
Executes swaps and manages liquidity operations in a stateless and upgradeable manner.
Factory Contract:
Enables the permissionless creation of trading pairs, expanding the token swap universe within the CrossFi Chain.
Pair Contracts:
Maintain real-time reserve balances and execute pricing via the constant product formula (x * y = k). This ensures accurate price discovery and reliable liquidity for all supported pairs.
To support external integration, xSwap provides a robust API layer that grants developers access to real-time data, optimal route calculations, and direct contract interactions. These tools empower builders to compose advanced DeFi strategies, create custom trading interfaces, and launch novel financial applications atop the CrossFi Chain.
xSwap delivers tangible advantages to its participants and plays a critical role in strengthening the overall financial infrastructure of the CrossFi ecosystem.
Market Efficiency
Through real-time execution, dynamic pricing, and consistently deep liquidity, xSwap provides a reliable trading experience with minimized slippage and stable execution even during high-volume market activity.
Incentivized Participation
The protocol’s fee-sharing model and upcoming farming functionality ensure that liquidity providers are continuously rewarded, encouraging sustained capital participation and enhancing market depth.
Capital Formation & Strategic Distribution
With the Bond mechanism, CrossFi fosters long-term ecosystem alignment by enabling discounted token distribution with programmable vesting, attracting strategic investors rather than short-term speculators.
Developer-Driven Growth
An open API, transparent contract architecture, and permissionless pool creation allow developers to rapidly build, integrate, and innovate—fueling ecosystem expansion and technological diversification.
Together, these benefits contribute to a robust increase in capital utility, protocol adoption, and Total Value Locked (TVL), reinforcing CrossFi as a resilient and forward-looking DeFi environment.
xSwap redefines what a decentralized exchange can be on the CrossFi Chain—combining seamless token swaps, deep and incentivized liquidity, strategic bonding mechanisms, and soon, powerful yield farming opportunities. Its fully decentralized and transparent architecture empowers both everyday users and liquidity providers, while the open, modular API fosters a vibrant developer ecosystem capable of building the next wave of DeFi applications.
As a core component of CrossFi’s infrastructure, xSwap not only improves on-chain trading but also drives sustainable ecosystem growth, capital efficiency, and community-led innovation.
