Querying the Cow Subgraph

The Subgraph is constantly indexing the protocol, making all the information more accessible. It provides information about trades, users, tokens and settlements. Additionally, it has some data aggregations which provides insights on the hourly/daily/totals USD volumes, trades, users, etc.
The SDK provides just an easy way to access all this information.
You can query the Cow Subgraph either by running some common queries exposed by the CowSubgraphApi or by building your own ones:
const chainId = 1 // Mainnet
const cowSdk = new CowSdk(chainId)
// Get CoW Protocol totals
const { tokens, orders, traders, settlements, volumeUsd, volumeEth, feesUsd, feesEth } =
await cowSdk.cowSubgraphApi.getTotals()
console.log({ tokens, orders, traders, settlements, volumeUsd, volumeEth, feesUsd, feesEth })
// Get last 24 hours volume in usd
const { hourlyTotals } = await cowSdk.cowSubgraphApi.getLastHoursVolume(24)
// Get last week volume in usd
const { dailyTotals } = await cowSdk.cowSubgraphApi.getLastDaysVolume(7)
// Get the last 5 batches
const query = `
query LastBatches($n: Int!) {
settlements(orderBy: firstTradeTimestamp, orderDirection: desc, first: $n) {
const variables = { n: 5 }
const response = await cowSdk.cowSubgraphApi.runQuery(query, variables)
