Launch a pump.fun coin from your bot wallet with your main wallet set as creator. The bot signs and pays; the main wallet shows as dev and receives creator fees.
Switch your wallet extension to the bot account before connecting.
Not connected
The bot wallet is still visible on-chain as the signer and fee payer. Anyone opening the create transaction on Solscan can see it. Do a small test launch first to confirm pump.fun shows your main wallet as dev.
