like-pump

Dual Pumpfun and Pumpswap for simpler buy and sell

npm i like-pump

It automatically handles migrated tokens.

Usage

const Pump = require('like-pump')

const pump = new Pump({ key: '<... base58 private key>' })

const mint = '2fWkVf417bfxEgUemymkYNagXVitnmNxvq7dhUwnpump'

const sigBuy = await pump.buy(mint, 0.00001)
console.log(sigBuy)

const sigSell = await pump.sell(mint, Infinity)
console.log(sigBuy)

API

pump = new Pump(options)

Creates a dual Pumpfun and Pumpswap instance.

Options:

{
  rpc: new SOL.RPC(),
  keyPair: new SOL.Keypair(key),
  key, // Can be a base58 string, otherwise a buffer
  recentBlockhash: null // E.g. new SOL.recentBlockhash()
}

The keyPair option takes priority over the key option.

Better to simply use the key option by passing the private key.

reserves = await pump.getReserves(mint)

Returns:

{
  curve, // Can be null or have the bonding curve
  pool // Can be null or have the pool reserves
}

mcap = await pump.marketCap(mint)

Calculates the market cap.

availableFees = await pump.availableFees([creator])

Gets the pending creator fees from the vaults.

The creator by default is pump.keyPair.publicKey.

signature = await pump.collect()

Collects the vault fees that are pending.

collectedFees = await pump.collectedFees([creator])

Get the already claimed creator fees.

The creator by default is pump.keyPair.publicKey.

totalFees = await pump.totalFees([creator])

Get the total creator fees.

The creator by default is pump.keyPair.publicKey.

sig = await pump.buy(mint, quoteIn[, options])

Buy a pump token.

Options:

{
  reserves: null, // Useful for batch concurrent buys, e.g. pump.getReserves(mint)
  slippage: 0.05, // 5% slippage
  transact: true, // Set to false to return instructions instead of sending the tx
}

sig = await pump.sell(mint, baseIn[, options])

Sell a pump token.

The baseIn amount can be Infinity to sell all tokens.

Options:

{
  reserves: null, // Useful for batch concurrent buys, e.g. pump.getReserves(mint)
  slippage: 0.05, // 5% slippage
  transact: true, // Set to false to return instructions instead of sending the tx
}

The transact option can also be an object e.g. { unitPrice: 0.001 }.

signature = await pump.transact(tx[, options])

Sign and send a transaction.

Options:

{
  recentBlockhash: null, // Optional but recommended to optimize by avoiding a request
  signers: [pump.keyPair], // The `signers` option takes priority over the below `keyPair` option
  keyPair: pump.keyPair,
  unitPrice: 0.0, // E.g. 0.0001 for buys and 0.001 for sells
  payer: null, // Payer of tx fees (First signer by default)
  confirmed: false,
  finalized: false
}

user = await pump.user(address)

Get the user profile.

Returns:

{
  address: '...',
  likes_received: 1,
  unread_notifs_count: 3,
