Pool queries

Endpoint: https://subgraph.barkswap.fi/subgraphs/name/barkswap/core

These are the queries the BarkSwap app uses for pool data.

List pools

query PoolsList {
  pools {
    id
    fee
    deployer
    token0 { id symbol name decimals derivedMatic }
    token1 { id symbol name decimals derivedMatic }
    sqrtPrice
    liquidity
    tick
    tickSpacing
    totalValueLockedUSD
    volumeUSD
    feesUSD
    token0Price
    token1Price
    poolDayData(first: 1, orderBy: date, orderDirection: desc) {
      id
      date
      feesUSD
      tvlUSD
      volumeUSD
    }
  }
}

Add first, skip, orderBy, and where to paginate/sort, e.g. the top pools by TVL:

{
  pools(first: 20, orderBy: totalValueLockedUSD, orderDirection: desc) {
    id
    token0 { symbol }
    token1 { symbol }
    totalValueLockedUSD
  }
}

A single pool

id is the pool address, lowercased.

query SinglePool($poolId: ID!) {
  pool(id: $poolId) {
    id
    fee
    token0 { id symbol decimals }
    token1 { id symbol decimals }
    sqrtPrice
    liquidity
    tick
    tickSpacing
    totalValueLockedUSD
    volumeUSD
  }
}

{ "poolId": "0x1234abcd…" }

Pools for a token pair

{
  pools(where: { token0: "0xaaa…", token1: "0xbbb…" }) {
    id
    fee
    totalValueLockedUSD
  }
}

Pool ticks (liquidity distribution)

Ticks are paginated 1000 at a time; increment skip until you get fewer than 1000 back.

query allTicks($poolAddress: String!, $skip: Int!) {
  ticks(
    first: 1000
    skip: $skip
    where: { poolAddress: $poolAddress }
    orderBy: tickIdx
  ) {
    tickIdx
    liquidityNet
    liquidityGross
    price0
    price1
  }
}

{ "poolAddress": "0x1234abcd…", "skip": 0 }

Daily history

{
  pool(id: "0x1234abcd…") {
    poolDayData(first: 365, orderBy: date, orderDirection: desc) {
      date
      volumeUSD
      feesUSD
      tvlUSD
    }
  }
}
