Fetch Pumpswap Pools based on a single Token Address or a Liquidity Pair
Pump AMM, the native decentralized exchange for Pump.fun tokens, utilizes liquidity pools to facilitate trading. Each pool is defined by a liquidity pair of token mint addresses. This pair is denoted by baseMint and quoteMint addresses on Pumpswap. We can add filters to these two fields, to retrieve specific pool details involving a particular liquidity pair.
For instance we are trying to get liquidity pools involving USDC and SOL, so we filter baseMintand quoteMintfields using the _in filter.
You can directly copy paste this code on replit and see it in action.
Fetch Pool by Liquidity Pair (USDC-SOL)
async function getPoolDetailsByLiquidtyPair(mintAddressA, mintAddressB) {
const SHYFT_API_KEY = "YOUR_SHYFT_API_KEY";
//query to get pool details on PumpSwap by liquidity pair
const operationsDoc = `
query MyQuery {
pump_fun_amm_Pool(where: {base_mint: {_in: ${JSON.stringify([
mintAddressA,
mintAddressB,
])}},
quote_mint: {_in: ${JSON.stringify([
mintAddressA,
mintAddressB,
])}}})
{
base_mint
creator
index
lp_mint
lp_supply
pool_base_token_account
pool_bump
pool_quote_token_account
quote_mint
pubkey
}
}
`; //you can cherrypick the fields as per your requirement
const result = await fetch(
`https://programs.shyft.to/v0/graphql/accounts?api_key=${SHYFT_API_KEY}&network=mainnet-beta`, //SHYFT's GQL endpoint
{
method: "POST",
body: JSON.stringify({
query: operationsDoc,
variables: {},
operationName: "MyQuery",
}),
}
);
const { errors, data } = await result.json();
console.dir(data, { depth: null });
}
getPoolDetailsByLiquidtyPair("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","So11111111111111111111111111111111111111112");
//getting USDC_SOL pairs, you can get other tokens by just changing the address
We can also query liquidity pool involving a particular token address, for that we would have to filter the baseMint or quoteMint field using the _in filter.
Fetch Pools involving a Token (USDC)
async function getPoolsForAToken(mintAddress) {
const SHYFT_API_KEY = "YOUR_SHYFT_API_KEY";
//query to get pool details on PumpSwap involving one token
const operationsDoc = `
query MyQuery {
pump_fun_amm_Pool(where: {_or: [{_or: {base_mint: {_eq: ${JSON.stringify(
mintAddress
)}}}},{_or: {quote_mint: {_eq: ${JSON.stringify(
mintAddress
)}}}}]}) {
base_mint
creator
index
lp_mint
lp_supply
pool_base_token_account
pool_bump
pool_quote_token_account
quote_mint
pubkey
}
}
`; //you can cherrypick the fields as per your requirement
const result = await fetch(
`https://programs.shyft.to/v0/graphql/accounts?api_key=${SHYFT_API_KEY}&network=mainnet-beta`, //SHYFT's GQL endpoint
{
method: "POST",
body: JSON.stringify({
query: operationsDoc,
variables: {},
operationName: "MyQuery",
}),
}
);
const { errors, data } = await result.json();
console.dir(data, { depth: null });
}
getPoolsForAToken("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v");
//for getting all pools involving USDC
