PUMPMCP never holds your keys. Every action starts with current chain state and a transaction simulation.
01 / Read the receipt
Coin name, the ends of its address, what you pay, what you get at least, every fee and the most that can leave your wallet. Match the code to your agent.
02 / Set the limits
Your minimum receive or maximum spend is part of the transaction. A sign link expires in 120 seconds and works once.
03 / Make the call
Remote actions open your wallet. Local actions ask you in your client or a local page, with default caps of 0.5 SOL per trade and 2 SOL per day.
07 / Just ask
Thirteen ways to read the market. Four ways to act. Tap a question to copy it, then paste it into your agent.
