Synthetix Subgraph
The Graph exposes a GraphQL endpoint to query the events and entities within the Synthetix system.
Synthetix has three bundled subgraps, all generated from this one repository:
- Minting, Burning and Transferring SNX & Synths: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix
- Synth Exchange Volume and fees generated: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix-exchanges
- Historical rates on-chain for the various synths to USD: https://thegraph.com/explorer/subgraph/synthetixio-team/synthetix-rates
Using this as a JS module
Supported queries
exchanges.since({ timestampInSecs = 1 day ago })Get the lastNexchanges since the given timestampInSecs (in seconds, so one hour ago is3600). These are ordered in reverse chronological order.exchanges.total()Get the total exchange volume, total fees and total number of unique exchange addresses.depot.userActions({ user })Get all depot deposit (sUSD) actions for the given user -deposit,withdrawl,unaccepted,removed.depot.clearedDeposits({ fromAddress, toAddress })Get all cleared synth deposits (payments ofETHforsUSD) either from a givenfromAddressor (and as well as) to a giventoAddress
How to query via the npm library (CLE)
# get last 24 hours of exchange activity, ordered from latest to earliest
npx synthetix-subgraph exchanges.sinceUse as a node or webpack dependency
const snxData = require('synthetix-subgraph');
snxData.exchanges.since().then(exchanges => console.log(exchanges));Use in a browser
<script src="//cdn.jsdelivr.net/npm/synthetix-subgraph/index.min.js"></script>
<script>
window.snxData.exchanges.since().then(console.log);
</script>Or 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
100results will be returned (the maximum allowedfirstamount). The way around this is to use paging (using theskipoperator in GraphQL). See the functionpageResultsin index.js for an example.
