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.
