MeteoraDAMM2
Meteora DAMM v2¶
Meteora constant-product pools (v2). Includes pool discovery, pricing, and swap builders with typed SwapParams.
Overview¶
- Class:
MeteoraDamm2 - Core:
DAMM2Core,DAMM2SwapBuilder,SwapParams
Quickstart¶
from CobraRouter.CobraRouter.router.meteora_damm_v2.damm2_swap import MeteoraDamm2
from solders.keypair import Keypair
md2 = MeteoraDamm2(async_client)
pool = await md2.core.find_pools_by_mint(mint)
state = await md2.core.fetch_pool_state(pool)
swap_params = await md2.build_swap_params(state, pool, mint, tokens_in=1000000, keypair=keypair)
tx = await md2.buy(swap_params, keypair)
API¶
from solders.keypair import Keypair
from solders.pubkey import Pubkey
from typing import Optional
class MeteoraDamm2:
core: "DAMM2Core"
async def build_swap_params(self, state: dict, pool: str | Pubkey, base_mint: str | Pubkey, tokens_in: int, keypair: Keypair, minimum_amount_out: int = 0) -> "SwapParams": ...
async def swap(self, action: str, pool: str | Pubkey, state: dict, keypair: Keypair, tokens_in: int | None = None, slippage: float = 0.5, percentage: float | None = None) -> str | None: ...
async def buy(self, params: "SwapParams", keypair: Keypair, return_instructions: bool = False): ...
async def sell(self, params: "SwapParams", keypair: Keypair, return_instructions: bool = False): ...
async def close(self) -> None: ...
class DAMM2Core:
async def fetch_pool_state(self, pool_address: str | Pubkey) -> dict: ...
async def find_pools_by_mint(self, mint: str | Pubkey, sol_amount: float = 0.01, limit: int = 10) -> str | None: ...
async def get_price(self, mint: str | Pubkey | None = None, *, pool_addr: str | Pubkey) -> dict | None: ...
Note
tokens_in are base token units for buy/sell in builder methods; UI conversions required.
Temporary WSOL accounts are created and closed automatically.
swap(action=...) convenience path builds and sends a transaction directly.
Pricing¶
DAMM2Core.get_price(pool_addr=...) returns a dict with pool, token_mint, and price (SOL per 1 token).
