Synthetix Subgraph

The Graph exposes a GraphQL endpoint to query the events and entities within the Synthetix system.

Synthetix has four bundled subgraps, all generated from this one repository:

1. Minting, Burning and Transferring SNX & Synths: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix
2. Synth Exchange Volume and fees generated: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix-exchanges
3. Historical rates on-chain for the various synths to USD: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix-rates
4. Depot deposits, withdrawls and successful exchanges: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix-depot

To query these subgraphs

Please use our node & browser utility: synthetix-data.

Or to query the subgraphs without any JS library

In it's simplest version (on a modern browser assuming async await support and fetch):

// Fetch all Exchanges in the last 24hrs s
(async () => {
  const ts = Math.floor(Date.now() / 1e3);
  const oneDayAgo = ts - 3600 * 24;
  const body = JSON.stringify({
    query: `{
      synthExchanges(
        orderBy:timestamp,
        orderDirection:desc,
        where:{timestamp_gt: ${oneDayAgo}}
      )
      {
        fromAmount
        fromAmountInUSD
        fromCurrencyKey
        toCurrencyKey
        block
        timestamp
        toAddress
        toAmount
        toAmountInUSD
        feesInUSD
      }
    }`,
    variables: null,
  });

  const response = await fetch('https://api.thegraph.com/subgraphs/name/synthetixio-team/synthetix-exchanges', {
    method: 'POST',
    body,
  });

  const json = await response.json();
  const { synthExchanges } = json.data;
  // ...
  console.log(synthExchanges);
})();

Note: due to The Graph limitation, only 100 results will be returned (the maximum allowed first amount). The way around this is to use paging (using the skip operator in GraphQL). See the function pageResults in synthetix-data for an example.
