Five of the agency's cats, in one extension, running in your own browser against your own wallet. Nothing here is advice, and nothing here has an edge until you have measured it.
CoinMarketCat — agentic trading for Solana in plain English: it trades spot tokens from a strategy you write, through your own Anthropic key, inside limits the model cannot change. Paper by default; set it up in Options. CoinMarketCat is not affiliated with CoinMarketCap.
Snipurr — the pump.fun sniper cat: it crouches ten seconds over every new launch and pounces only if the launch is still at or above its would-have entry price, inside limits you set on this page.
Popcat — the cat-coin scanner: new cat coins on pump.fun, each with its twelve on-chain checks, as text. It trades nothing.
CashCat — launches a cat coin of your own on pump.fun, from the autopilot wallet, after the same content rules and checks the agency's CashCat runs. Its auto mode is off until you arm it.
Crying Cat — the rug check: paste any mint and read what the chain says about its authorities, extensions, holders and curve.
This page sets up what the trading cats share — your RPC, Phantom, who signs — and Snipurr, the sniper cat's lane. The agent is set up in Options → Agent; CashCat's Pinata key in Options → CashCat.
1 Connect: an RPC, and your Phantom
The cat reads the chain through an RPC you choose. The public mainnet RPC refuses browsers, so paste one from Helius, Triton or QuickNode. It stays in this browser.
Phantom only runs inside web pages, so it lives on the console page. Open it and press Connect Phantom there. In Phantom mode, keep that tab open: every trade is one approval window on it.
Phantom: not connected
2 Pick a style
A style fills in your limits. Every style keeps the entry rule the record supports: wait 10 s, and buy only a launch that still marks at or above its would-have fill. You can change any number in the next step, and later in Options.
3 Your limits
These are hard limits. The lane never spends more than the ticket on one launch or more than the day's budget in any rolling 24 hours, and a live position always leaves in full at the first exit that fires.
4 Stock tokens to focus on (optional)
pump.fun lets a launch be priced in a tokenised stock (xStocks) instead of SOL. Tick a stock and the cat may pay for such a launch with that stock, from the stock already in the wallet it trades from. Leave everything unticked and the cat stays SOL-only.
Amounts here are in that stock's own units (for example 0.01 GLDx), not SOL. The network fee and account rent of a stock trade are still paid in SOL and count against your SOL budget.
Nothing about stock-priced launches has been measured: no win rate, no fee on a buy. Every xStock's issuer can freeze, pause or claw it back. Listing a stock means the lane will not arm until you have chosen a stop.
5 Who signs each trade
What autopilot changes. A key in a browser is a bigger attack surface than Phantom: it is encrypted under your passphrase at rest, but while it is unlocked, malware on this machine or a hostile extension could read it. What is at risk is what you fund it with — the balance caps your exposure. Locking clears the unlocked key; sweeping sends everything back to Phantom.
Create the autopilot wallet now. Choose a passphrase of at least 12 characters and write it down somewhere that is not this browser: there is no reset.
Then, in the popup: Fund from Phantom (one approval, default: your daily budget), Unlock, and arm. Sweep back returns everything to Phantom when you are done.
6 Start in Observe
Saving puts the lane in Observe: the cat evaluates every launch, keeps a would-have book, and signs nothing. Watch it, export the book, and grade it before any money moves.
How arming works. When you are ready, choose Execute in the popup. The lane prints a checklist — every item must be green — and a sentence naming your wallet and your limits. Type that sentence exactly and press Arm. Change a limit, a stock or the signer, and the sentence changes: you type it again.
Set up.
Click the cat in the toolbar for the popup. Everything here is editable in Options, and this page is there too, under “run the setup again”.
