[Guide] Market Making Tool

Market Making Tool #

The market making tool automatically performs buy, sell, gas top-up, collection, and batch transfer actions for a token. It manages the main wallet and trading wallets locally in the browser, then keeps running according to your transaction interval, buy probability, buy amount range, and sell ratio settings.

Steps #

  1. Open the market making tool and connect your wallet.

  5. Generate or import trading wallets. Before importing private keys, make sure the device is trusted and existing wallets are backed up.
  6. Set the transaction interval, buy probability, buy amount range, sell ratio, and minimum sell threshold.
  7. If needed, set Gas Limit, Gas Price, or choose a more stable RPC node.

FAQ #

  • Can I close the page after starting? No. The tool runs locally in the browser, so the page must stay open while trading is running.

  • Why do changed parameters not take effect immediately? A running task continues using the configuration from when it started. Stop trading, update the parameters, and restart.

  • Why do some wallets automatically switch to buy? If the selected wallet does not have enough tokens to sell, the tool switches to buy to keep the process running.

  • Are private keys safe? The tool uses private keys locally for automated trading, but private keys are highly sensitive. Use only trusted devices and back up or remove wallets you no longer need.
