MetaTdex

MetaTdex is a decentralized trading protocol built around an order book, with matching, clearing and custody all executed by smart contracts. The interface resembles a centralized exchange, but orders are signed in the user's wallet; bids and asks sit on an on-chain order table and the contract moves funds on fill, avoiding the slippage an automated market maker curve produces on large trades.

It is deployed on BNB Chain, Polygon, Arbitrum and HECO, with a multichain wallet, a bridge and maker rebates that return part of each fee to liquidity providers to offset resource costs. The platform token carries governance voting, staking and tiered benefits, and its node network is organized by region. Early traction centred on Turkey and the Middle East, where it was catalogued as an order-book exchange rather than an AMM.
