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.

​
Common Use Cases

  • Stock & Equity Trading: Enable users to trade in and out of tokenized stocks using stablecoins inside your application.
  • Cross-Chain Treasury Rebalancing: Automatically sweep or balance treasury funds across different EVM chains into stablecoins on a single primary network.
  • In-App Asset Conversion: Allow users to convert BTC or ETH directly into stablecoins or tokenized equities.
  • Same-Chain Swaps & Token Trading: Execute instant, low-cost asset swaps between native tokens, stablecoins, and altcoins on the same blockchain network without leaving your application.
