# Platform Mechanics Unigox automates crypto-fiat trades using four core systems: #### **On-chain escrow** Crypto is held in a smart contract on the Unigox appchain until fiat payment is confirmed. Both parties can verify escrow status at any time. #### **Liquidity aggregation** Every order is matched against multiple sources — P2P vendors, licensed exchanges, and business integrations. You get the best available rate without browsing through offers. #### **Non-custodial wallet with gasless transactions** Users control their own keys. Create a wallet with email or connect an existing wallet (MetaMask, Rabby, Phantom). Send tokens like USDT or USDC on the Unigox appchain without needing a gas token. #### **Automated matching engine** Orders are matched instantly to the best available offer based on amount, currency, and payment network. No chats. No manual approvals. Transfer fiat to the provided bank details and the trade completes automatically. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
