  $ pip install .

Usage

Check out the example.py script for a plug&play implementation

class PumpSwap(
    async_client: AsyncClient,
    signer: Keypair
)

(method) def buy(
    pool_data: dict,
    sol_amount: float,
    slippage_pct: float,
    fee_sol: float
) -> Coroutine[Any, Any, bool]
Args:
    pool_data: dict
    sol_amount: float
    slippage_pct: float
    fee_sol: float
Returns:
    bool: True if successful, False otherwise

(method) def sell(
    pool_data: dict,
    sell_pct: float,
    slippage_pct: float,
    fee_sol: float
) -> Coroutine[Any, Any, bool]
Args:
    pool_data: dict
    sell_pct: float
    slippage_pct: float
    fee_sol: float
Returns:
    bool: True if successful, False otherwise

(function) def fetch_pool(
    pool: str,
    async_client: AsyncClient
) -> Coroutine[Any, Any, dict[str, Any]]

(function) def fetch_pool_base_price(
    pool_keys: Any,
    async_client: Any
) -> Coroutine[Any, Any, tuple[Decimal, Any, Any] | None]

Examples

  # 1) Initialize PumpSwap client
  client = PumpSwap(async_client, signer=async_payer_keypair)

  # Example pool: https://solscan.io/account/9NXBQSt63ZZcw3e4DhbDPGP2FjnwW3aDJWEXRwcGEsN3
  pool = "9NXBQSt63ZZcw3e4DhbDPGP2FjnwW3aDJWEXRwcGEsN3" # Change this to the token pool address you want to buy

  # 2) Fetch pool data
  pool_keys = await fetch_pool(pool, async_client) 
  base_price, base_balance_tokens, quote_balance_sol = await fetch_pool_base_price(pool_keys, async_client)
  decimals_base = 6 # Pump.fun mints got 6 decimals, otherwise it can be read from Pool Creation, or Mint Creation transaction

  # 3) Prepare pool data
  pool_data = {
      "pool_pubkey": Pubkey.from_string(pool),
      "token_base": Pubkey.from_string(pool_keys["base_mint"]),
      "token_quote": Pubkey.from_string(pool_keys["quote_mint"]),
      "pool_base_token_account": pool_keys["pool_base_token_account"],
      "pool_quote_token_account": pool_keys["pool_quote_token_account"],
      "base_balance_tokens": base_balance_tokens,
      "quote_balance_sol": quote_balance_sol,
      "decimals_base": decimals_base
  }

  await client.buy(
      pool_data,
      sol_amount=0.002,
      slippage_pct=10,
      fee_sol=0.0005,
  )

  await client.sell(
      pool_data,
      sell_pct=100,
      slippage_pct=10,
      fee_sol=0.0005,
  )
