# Assets Swaps

The OpenXSwitch Swap API allows developers to execute instant same-chain and cross-chain asset swaps programmatically across supported blockchain networks. By routing liquidity through decentralized exchanges (DEXs), automated market makers (AMMs), and Request-for-Quote (RFQ) venues, OpenXSwitch provides fast, low-cost asset conversions directly within your user wallets or treasury operations.

#### Supported Liquidity & Asset Routes

* **EVM Cross-Chain & Same-Chain Swaps:** Enables capital-efficient, high-speed DEX swaps across Ethereum L1 and EVM L2s (Arbitrum, Optimism, Base, Polygon) with minimal slippage.
* **Tokenized Stock Swaps (via Robinhood Chain):** Facilitates instant on-chain swaps between Robinhood Stock Tokens (e.g., NVDA, AAPL, SPY) and stablecoins (e.g., USDG) via native RFQ execution.
* **Bitcoin & Non-EVM Swaps (*Coming Soon*):** Enables decentralized cross-chain swaps between native Bitcoin (BTC) and EVM ecosystems.

#### Key Benefits

* **Unified API Interface:** Swap digital assets and tokenized stocks across disparate blockchains using a single RESTful endpoint.
* **Gasless Execution:** Integrate with OpenXSwitch's built-in ERC-4337 Paymaster infrastructure to execute swaps gaslessly or allow users to pay route fees in stablecoins.
* **Auto-Routing:** Automated routing across DEX venues to guarantee optimal liquidity depth and execution speed across crypto and tokenized equities.
* **Low-Cost Settlement:** Capital-efficient trade routing with transparent execution fees starting as low as 0.0.5% per swap.

#### How Asset Swaps Work

1. **Request a Quote:** Query the OpenXSwitch Swap API with the source chain, source asset, destination chain, destination asset, and amount.
2. **Review Execution Parameters:** The API queries underlying DEX aggregators to return live exchange rates, expected slippage, estimated execution time, and fee breakdown.
3. **Generate CallData & Execute:** The DEX or liquidity venue generates the optimized transaction `callData`. OpenXSwitch then securely signs and executes the transaction on-chain on behalf of the smart wallet or treasury account.
4. **Monitor Lifecycle:** Track settlement status in real-time via OpenXSwitch Webhooks.

#### Security & On-Chain Execution

* **DEX-Generated CallData:** OpenXSwitch queries decentralized exchange protocols to construct calibrated, optimized `callData` payload parameters without exposing private keys or taking unneeded custody during route generation.
* **TEE Security & On-Chain Execution:** Every transaction payload is validated, signed, and broadcast inside OpenXSwitch’s secure **Trusted Execution Environment (TEE)**. This ensures key isolation, hardware-enforced integrity, and institutional-grade transaction orchestration directly to the destination blockchain network.
* **Slippage & Deadline Controls:** Every generated swap payload includes strictly enforced slippage tolerance bounds and transaction execution deadlines to protect users from front-running, sandwich attacks, or extreme market volatility.
