MetaTdex provides users with both asset security of DEX and smooth trading experience of CEX. There is no Gas fee for pending orders on MetaTdex. Besides, after an order is completed, the matching fee will be paid in USDT instead of the on-chain Gas fee. So users no longer need to prepare mainchain tokens for gas fee payment.
Currently, MetaTdex's orderbook matching mode only supports Polygon chain and two trading pairs (WBTC/USDT and WETH/USDT). The quantity of trading pairs and public blockchains will gradually increase in the future. MetaTdex is committed to bringing users a more convenient trading experience with great depth, fast trading speed, zero slippage, free Gas fee and more.
1. 0 Fee for Pending Orders:
There will be no fees if a pending order is not successfully traded. At the same time, the transaction fee has been substantially reduced compared to the original basis.
2. Gas-Borrowing Transactions with More Convenience:
Users no longer have to prepare or covert for the Gas fee required MATICs in advance. In the Gas-borrowing transaction service, users are able to select the token they want to trade and pend orders directly. When a transaction is completed, the system will automatically deduct a corresponding amount of USDTs as Gas fee. Hence, there is no need for users to prepare or covert for MATICs any more. This newly launched function enables users to trade in a more convenient and time-saving way.
Definition of Product Terms
- Match Engine: Centralized monitoring and smart matching for reverse pending orders, greatly reducing the Gas fee required for original tdex users to pend orders.
- Match Efficiency: Pending orders near the orderbook, and the time for an pending order to be executed is about 10-120 seconds.
- Pending Order: Under the 0x protocol, no Gas fee is required for pending orders. User assets will be deducted only after the matching is successful.
- Cancel Order: There is no need to pay Gas fee for active order cancellation. If an order is not executed within 1 hour after pending, the system will automatically cancel the order without charging Gas fee.
- Match-Based Order: An order is matched and executed successfully according to the pending order amount and target token quantity. During the process, users need to pay the matching fee, while the transaction fee is deducted from the target tokens acquired by users. User orders are completely executed on the blockchain so that the corresponding data is truthful and verifiable.
- Match Fee: The match fee, required for the successful execution of a pending order, is mainly used for hedging the transaction fee and on-chain trading Gas fee (uniformly deducted in USDT). Affected by the fluctuation of on-chain Gas price, the match fee fluctuates from 0.2 USDT to 1.0 USDT.
- Transaction Fee: After an order is matched and executed successfully, a 0.2% transaction fee will be deducted in target token of the order as the platform income.
