How to use

• Use the endpoints to control, send any POST requests to:

  2. http://localhost:3000/api/monitor/stop for stop(all current tokens will be processed, new tokens will be stopped monitored).
• Check logs in a console.

Config setup

See .env.example Create .env file in the project root near the env.example and write the config from .env.example on it.

MAX_LAMPORTS = max transaction fee for each TX(150000 ~= 0.000155 SOL)
MAX_RETRIES = max retries to send a new token
TOKEN_AA_ADDRESS = Solana address by default is "So11111111111111111111111111111111111111112", do not touch it
TOKEN_AA_DECIMALS = Solana decimals by default is "9", do not touch it
TOKEN_AA_AMOUNT = the SOL amount for which new tokens should be purchased
TX_DIRECTION = transaction direction by default is "in", do not touch it
SELLING_TIMEOUT = time to sell a new token(1000 = 1sec)
IS_BURNED_CHECK = use LP burned check for new tokens

SOLANA_RPC_URL = https://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY
SOLANA_WS_URL = wss://mainnet.helius-rpc.com/?api-key=YOUR_API_KEY
PAYER_WALLET_PRIVATE_KEY = Your Solana wallet private key like: "wG7LPvk...Z6gSEeZ". Tokens will be bought/sold from this wallet, also paid fee.

Tips and tricks

• Don't use free RPC nodes.
• Try increasing fees(MAX_LAMPORTS) to increase the prioritization of your transactions.
• When setting a timeout for token sales, please note that sending and confirming the transaction will take time too.
