# DeFi Swaps & Bridges

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

### Supported Liquidity & Asset Routes

* **Cross-Chain Bridges (EVM, Solana, TRON & Bitcoin):** Bi-directional bridging and liquidity routing between Solana, TRON, Bitcoin, and EVM ecosystems (Ethereum, Arbitrum, Optimism, Base, Polygon) to swap assets seamlessly with minimal slippage.
* **Same-Chain Swaps (EVM, Solana, TRON & Bitcoin):** High-speed, capital-efficient DEX swaps executed natively within supported chains.
* **Tokenized Stock Swaps (via Robinhood Chain):** Instant on-chain swaps between Robinhood Stock Tokens (e.g., NVDA, AAPL, SPY) and stablecoins (e.g., USDG) via native RFQ execution.

### Key Benefits

* **Unified API Interface:** Swap and bridge digital assets and tokenized equities across disparate blockchains using a single RESTful endpoint
* **Gasless Execution:** Integrated ERC-4337 Paymaster and Solana Gas Station infrastructure enable gasless transactions or route fee payments in stablecoins.
* **Automated Routing:** Dynamic execution across DEX and bridge venues to guarantee optimal liquidity depth and execution speed.
* **Low-Cost Settlement:** Capital-efficient trade routing with transparent execution fees starting at 0.05% per swap.

### How DeFi Swaps & Bridges Work

1. **Request a Quote:** Query the API with source and destination chains, target assets, and swap amount.
2. **Review Execution Parameters:** Live exchange rates, expected slippage, estimated execution time, and fee breakdowns are returned automatically.
3. **Generate CallData/Address & Execute:** The liquidity venue generates the optimized transaction `callData/Address`. OpenXSwitch then securely signs and executes the transaction on-chain on behalf of the smart wallet or treasury account.
4. **Monitor Lifecycle:** Real-time settlement or refund statuses are tracked via OpenXSwitch Webhooks.

### Security & On-Chain Execution

* **Protocol-Generated CallData/Address:** OpenXSwitch queries decentralized exchange and bridging protocols to construct calibrated, optimized `callData/Address` 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 a secure Trusted Execution Environment (TEE) for hardware-enforced key isolation.
* **Slippage & Deadline Controls:** Strictly enforced slippage bounds and execution deadlines protect transactions from front-running, sandwich attacks, and market volatility.
