DON

Decentralized Oracle Network

On demand Oracle system.

Chainlink price feeds are used in most cases, but prices are updated every few minutes/ hours depending on volatility. DEXYNTH trades synthetic assets, meaning that it does not generate any price for trading pairs. The need of a real time price feed, gives origin to our DON. Every time a trade is open, it makes a request in real time to the 8 nodes, which fetch the price from the 8 exchanges’ high quality APIs, then sends the median to the custom aggregator contract and finally sends the median to the trading contract to execute the order with a real time price. The platform then leverages the existing Chainlink price feeds’ security by checking each of the on demand Chainlink nodes’ answers with the corresponding price feed, rejecting potential outliers.

This means you can open and close trades on all the trading pairs nearly instantly, instead of waiting in profit until the trading pair moves. Also avoids price manipulation, as the final price is a median and peaks are diluted.
