Real-Time Data

DexScreener operates by running blockchain nodes and indexers for each of the 100+ supported networks. When a trade occurs on any indexed DEX, DexScreener processes the transaction data from the blockchain and updates price, volume and liquidity metrics in near real time. This direct on-chain data collection is what makes DexScreener so accurate — there is no reliance on centralized exchange feeds or third-party price oracles.

Data Flow on DexScreener

Every swap event emitted by a DEX smart contract is captured by DexScreener's indexers, parsed into OHLCV (Open, High, Low, Close, Volume) data and served through the platform's API and frontend. This means you see the same price data that exists on-chain, with updates typically appearing within seconds of a block confirmation.
