We are DEx.top a decentralized exchange built on blockchain smart contract. We are the first decentralized exchange that utilizes ROC mechanism (Replayed on Chain).

Things We Promise:

Your funds are secure

Your deposits directly go to the smart contract https://github.com/dexDev/DEx.top, and your orders are signed by your private key. The smart contract ensures that your orders are executed or expire correctly and that withdrawals from your balance always go back to your wallet. DEx.top has no custody of or access to your funds, nor your private key. It is just a service of order matching and a source of liquidity. Don't trust the words - read the code https://github.com/dexDev/DEx.top.

Instant Trading

Order placing, canceling, matching and executing are all instant - no waiting for blockchain confirmation. It is made possible by our RoC (Replayed-on-Chain) mechanism: trading actions are confirmed on the off-chain ledger of DEx.top at first, and then asynchronously sent to the blockchain for settlement. The action sequence will be "replayed" by the smart contract to produce exactly the same trading history.

Less Gas, More Features

DEx.top smart contract is heavily optimized for gas cost efficiency. It uses bit-compaction to minimize the amount of input data and the size of contract state. It supports batch processing which can significantly reduce the amortized gas cost of trade execution (see our gas cost chart https://github.com/dexDev/DEx.top/blob/master/smart-contract/dextop-gas-cost.md). No gas cost for unfilled orders. Cost reduced, not the features - DEx.top smart contract supports IOC Order, Checked Order Expiration, Hard Order Cancellation, Fee Rebates and much more.
