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. Synthetix: issuing (aka minting) sUSD, burning sUSD and transferring SNX & Synths: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix
2. Exchanges: synth Exchange Volume and fees generated: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix-exchanges
3. Rates: 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 in the Depot: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix-depot
5. Loans: loans created and closed using EtherCollateral: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix-loans
6. Binary Options: Binary options data: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix-binary-options

To run and deploy locally

For any of the four subgraphs: snx, exchanges, rates, depot, loans and binary-options as [subgraph]

1. Run the npm run codegen:[subgraph] task to prepare the TypeScript sources for the GraphQL (generated/schema) and the ABIs (generated/[ABI]/*)
2. [Optional] run the npm run build:[subgraph] task for the subgraph
3. Deploy via npm run deploy:[subgraph]. Note: requires env variable of $THEGRAPH_SNX_ACCESS_TOKEN set in bash to work.

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.
