# Cross-Chain Swap Aggregation Protocol
WheelX Cross-Chain Swap Aggregation Protocol is an AI-powered aggregation and execution layer for bridging, intra-chain swaps, and cross-chain swaps across 50+ blockchains. It reduces liquidity fragmentation and routing complexity by combining bridges, DEXs, and liquidity sources into optimized transaction routes.
### High-Level Overview
WheelX acts as the central aggregation layer connecting major blockchains (Ethereum, Solana, Arbitrum, Base, BNB Chain, Tron, Bitcoin ecosystems, and more) through an AI routing engine. It selects the optimal paths by integrating leading bridges and DEXs for superior execution.
### Core Product Flows
* **Cross-Chain Bridge**: Move an asset between supported blockchain networks through a route optimized for cost, speed, liquidity, and reliability.
* **Intra-Chain Swap**: Exchange assets on the same blockchain using aggregated DEX and liquidity-pool quotes.
* **Cross-Chain Swap**: Exchange an asset and move it to another blockchain through a unified route.
### Business Benefits
* Dramatically improves user experience and conversion rates for wallets, dApps, and trading platforms.
* Increases cross-chain liquidity flow and capital efficiency for ecosystems and protocols.
* Provides enterprises and merchants with reliable, low-cost multi-chain payment rails.
* Reduces operational complexity for developers through simple SDK and API integration.
### Core Capabilities
* Support for **50+ blockchain networks** (EVM, Solana, Tron, Bitcoin ecosystems, etc.).
* Real-time aggregation across leading bridges and DEXs.
* Advanced AI-powered routing optimized for cost, speed, and liquidity depth.
* High-volume order handling with intelligent splitting.
* Enterprise-grade reliability and security.
### Instant Bridging & Onboarding
WheelX enables instant bridging and seamless onboarding across 50+ blockchains. By combining high-speed cross-chain liquidity with intelligent swap aggregation, users can deposit, withdraw, or onboard any token onto any supported chain quickly and efficiently.
#### Key Features
* **Ultra-Fast Bridging** — Median bridge times of just a few seconds across major networks.
* **Multi-VM & Broad Coverage** — Full support for leading EVM chains, Solana, Tron, Bitcoin ecosystems, and more.
* **WheelX Payment** — Onboard via direct transfers from centralized exchanges (CEX) or any wallet — no wallet connection required.
* **App & Partner Revenue** — Easy-to-implement fee system with automatic collection in stablecoins (USDC/USDT).
#### How It Works
WheelX uses intelligent cross-chain intents and AI-powered routing for low-cost, low-latency transfers. Users receive a real-time quote with exact time and cost. Upon acceptance, the transaction is validated and executed. Funds arrive instantly on the destination chain while source assets are handled securely in the background.
### Intra-Chain & Cross-Chain Swaps
WheelX supports intra-chain and cross-chain swaps across 50+ networks. It combines meta-aggregation across DEXs and liquidity pools with intelligent routing and high-speed bridging to optimize price, total cost, slippage, liquidity, and execution time.
#### Key Features
* **Smart Meta-Aggregation** — Aggregates the best on-chain swap providers and liquidity pools for superior routes.
* **Instant Cross-Chain Swaps** — Ultra-fast execution with median times of just a few seconds.
* **Multi-VM Support** — Comprehensive coverage across EVM, Solana, Tron, Bitcoin ecosystems, and beyond.
* **App & Partner Revenue** — Flexible fee system with automatic collection in stablecoins (USDC/USDT).
#### How It Works
Users receive a real-time quote detailing the expected output, time, and cost. Upon acceptance, WheelX validates the order and executes the selected route, whether it is an intra-chain swap or a cross-chain operation. Funds are delivered in the quoted destination asset.
### Integration Options
* **Bridging & Onboarding**: Add cross-chain transfers and CEX-to-chain deposits to wallets, dApps, or trading interfaces.
* **Swaps**: Integrate both intra-chain and cross-chain swaps.
Both are available via WheelX's Quote API and SDK. For technical details, refer to the [Quick Start](/api-and-developer/getting-started/quick-start.md).
### Strategic Impact
As the core engine of WheelX, the Cross-Chain Swap Aggregation Protocol serves as infrastructure for the multi-chain economy, helping users, partners, and enterprises access cross-chain liquidity through a unified experience.
