tokenSupply on each pool object is the total on-chain supply of the token mint (i.e. mint.supply adjusted for decimals), not a circulating supply estimate. It is what’s used together with price.usd to derive marketCap.usd, so marketCap.usd here is fully diluted market cap.SDK Example
import { Datastream } from '@solana-tracker/data-api';
const dataStream = new Datastream({
wsUrl: 'wss://datastream.solanatracker.io/YOUR_API_KEY',
});
await dataStream.connect();
const sub = dataStream.subscribe.token('6p6xgHyF7AeE6TZkSmFsko444wqoP15icUSqi2jfGiPN').on((data) => {
console.log(data);
});
// sub.unsubscribe();
