sapysol_raydium_amm

sapysol Raydium AMM V4 direct swap implementation. Based on JavaScript from Raydium SDK, written from scratch.

sapysol_raydium_amm fetches information from Solana blockchain and doesn't rely on Raydium public web APIs (https://api.raydium.io/v2/sdk/liquidity/mainnet.json), that means if you know pool address you can start trading right away without the need to wait for the Raydium pool cache to be updated.

WARNING! sapysol_raydium_amm is currently in alpha version, so, bugs, lack of tests and descriptions are expected. Some things may not work, future versions may bring breaking changes.

Installation

pip install sapysol

Note: Requires Python >= 3.10.

Usage

# Raydium AMM Swap, WSOL for MEW example
#
from solana.rpc.api      import Client
from sapysol             import *
from sapysol.token_cache import *
from typing              import List
from sapysol_raydium_amm import *

SetupLogging()

connection: Client  = Client("https://api.mainnet-beta.solana.com")
payer:      Keypair = MakeKeypair("/path/to/keypair.json")
POOL_ID:    Pubkey  = MakePubkey("879F697iuDJGMevRkRcnW21fcXiAeLJK1ffsw2ATebce") # MEW-WSOL AMM Pool ID

amm: SapysolRaydiumAMM = SapysolRaydiumAMM.FromPoolAddress(connection=connection, poolAddress=POOL_ID)
ixList = amm.GetSwapInstruction(walletAddress  = MakePubkey(payer),
                                tokenFrom      = WSOL,
                                tokenTo        = MEW,
                                amountIn       = 0.01,
                                inLamports     = False,
                                txComputePrice = 10_000)
tx: SapysolTx = SapysolTx(connection = connection, 
                          payer      = payer, 
                          txParams   = SapysolTxParams(maxSecondsPerTx=60, sleepBetweenRetry=1))
tx.FromInstructionsLegacy(ixList)
tx.Sign().SendAndWait()

But if you wanto FKIN SNIPE the pool that was not created yet, knowing only OpenBook Market ID, I got you! This library can pre-calculate all needed addresses from Market ID only! Transactions will fail until the actual pool is created of course, but you may be one of the first ones to make a buy.

Contributing

All contributions are welcome! Although the devil is in the details:

One of the main requirements is to keep the same coding style for all future changes.

If you want to help the project and implement adding/removing liquidity, etc - you are welcome!
