Real StalkChain answers captured 2026-10-01. Handles are public FOMO traders. ### Which tokens are 3+ tracked traders aping right now?

All 7 chains through one connector. Codex reads FOMO traders, StonkFun launches and wallet and token data on every one, from the last hour back to all-time. ## Can't Codex just look this up itself? Not well. FOMO sits behind a login, explorers show one wallet per tab, and Codex's memory stops at its training cutoff. StalkChain closes all three gaps. | | By hand | Codex alone | Codex + StalkChain | | --- | --- | --- | --- | | FOMO trader wallets, PnL and theses | In the app, one profile at a time, wallets hidden | Can't log in | FOMO handles resolved to real wallets | | Live entries, holders and flow | Refresh tab after tab | Web search snippets at best | Last hour, across 7 chains | | History: PnL, fills, prices, launches | Exports and spreadsheets | Training data, months old | 24h to all-time, fill by fill | | Dev, sniper and exit checks | Four sites, four tabs | Educated guesses | One question (on-chain checks on Solana) | | One wallet across every chain | One explorer per chain | Page by page, if it loads | Holdings on all 7 chains, one answer | ## What can Codex do with StalkChain? Ask like you'd ask the group chat. Codex picks the tools and comes back with wallets, dollar amounts and timestamps. - **Catch smart-money entries:** See which tokens three or more tracked traders bought in the last hour, who they are and how big they went. Example: "which tokens did 3+ tracked traders ape in the last hour? skip any where the dev already sold" - **Check a token before you ape:** Deployer's past launches, snipers, LP burn, wash-trade score and a real exit quote. Solana tokens. Example: "check this CA before i ape. snipers still in? deployer rugged before? can i exit $5k without eating 20% slippage?" - **Research a trader before you copy:** Real wallets, PnL from 24h to all-time, average hold time, open bags and the theses they wrote. Example: "research pricedin before i copy him. 30d vs all-time pnl, avg hold time, what's in his bags rn" - **See if KOLs are exiting:** How many tracked traders hold a token, what they paid, and what share of them sold recently. Example: "are the KOLs dumping $CATE? what % of tracked holders sold recently and who's still holding" - **Size up any wallet:** Holdings on all 7 chains for any address. On EVM, its age and who funded it. On Solana, its PnL. Example: "fresh wallet just aped $40k on Base. how old is it, who funded it, what else is it holding?" - **Go back in time:** All-time PnL, fill-by-fill trade history, past prices, a deployer's earlier launches and the theses traders posted. Example: "pull the top theses on $ORBIO. who posted with a real bag, and who sold after posting?" ## What is the StalkChain MCP? The StalkChain MCP is a Model Context Protocol server that gives Codex 70+ tools for live and historical blockchain data across 7 chains, FOMO trader activity included. - One link with OAuth sign-in. No API key needed in chat - 70+ tools for traders, tokens, wallets, launches and DeFi - Live and historical: last-hour entries, all-time PnL, past fills, price history - 7 chains: Robinhood Chain, Solana, Base, BNB Chain, Ethereum, Monad, Hyperliquid perps - Research tools read public data. Never asks for a seed phrase or private key - **Traders:** search, resolve to wallets, positions, fills, PnL per window, spotlight, followers - **Tokens:** holders, KOL holders, dev and insider bags, buy/sell flow, sell pressure - **Live:** alert feed, multi-trader entries, coordinated buys, live stream - **History:** all-time PnL, past fills, price history, launch records, exploits - **Solana on-chain:** deployer history, snipers, real holders, wash trading, exit liquidity - **Wallets & DeFi:** cross-chain portfolios, wallet age, yields, protocol risk ## How do I get a daily smart-money digest? Codex can't ping you, but codex exec runs without a chat window. Add StalkChain with an API key, schedule one script, and a fresh digest is waiting every morning. ```sh # digest.sh — run from cron or CI export STALKCHAIN_API_KEY=sc_your_key codex exec --skip-git-repo-check --ephemeral \ -c 'mcp_servers.stalkchain.default_tools_approval_mode="approve"' \ "7d FOMO leaderboard: top 10, one line each with pnl and biggest bag. flag any token 3+ of them hold." \ >> ~/stalkchain-digest.md # crontab -e: every morning at 08:00 0 8 * * * ~/digest.sh ``` ## Codex CLI, IDE extension or desktop app? It works in all three. - **Codex CLI:** OpenAI's coding agent in your terminal. One command adds StalkChain, and with an API key it runs on a schedule. (codex mcp add · or an API key) - **IDE extension:** Codex inside VS Code, Cursor and Windsurf. Add StalkChain from the gear menu, or reuse the server you added in the CLI. (Gear menu → MCP servers) - **ChatGPT desktop app:** Codex runs inside the ChatGPT app on Mac, Windows and Linux. Add StalkChain under Settings; it shares config with the CLI. (Settings → MCP servers) ## What does it cost? Connecting is free and needs no card. Free tools, like the live feed sample, work right away. Research lookups run on credit packs that never expire. ## Is it safe? You sign in with OAuth, so Codex never sees a password or API key. The research tools read public data, and StalkChain never asks for your seed phrase or private keys. Disconnect any time. ## Something not working? - **StalkChain tools don't show up:** Start a new chat and make sure StalkChain is enabled for it. - **A tool says you're out of credits:** The free tools keep working. Top up in your StalkChain dashboard, then ask again. - **Sign-in keeps looping:** Remove the connector, add the link again and approve once. ## FAQ ### What does StalkChain add to Codex? Data Codex can't reach on its own. One link gives it 70+ tools for live and historical blockchain data across 7 chains, plus FOMO trader activity: handles resolved to real wallets, PnL from 24h to all-time, positions and written theses. ### Why can't Codex read FOMO data by itself? FOMO's trader data sits behind a login, inside an app that only renders with JavaScript, so a plain web fetch comes back empty. StalkChain resolves FOMO handles to their Solana and EVM wallets and returns PnL, positions, fills and theses. ### How do I connect StalkChain to Codex? Run codex mcp add stalkchain --url https://data.stalkchain.com/mcp. Codex opens your browser; sign in and approve, no API key needed. In the ChatGPT desktop app or IDE extension, add the same link under MCP servers as Streamable HTTP. ### Which Codex plans can use it? Codex comes with every ChatGPT plan, from Free to Enterprise, or an OpenAI API key. OpenAI lists MCP support on Plus, Pro, Business, Enterprise, Edu and API-key sign-in. Free and Go get Codex in the desktop app, subject to rollout. ### Does it work in Codex Cloud? Not directly. Codex connects to custom MCP servers from your machine: the CLI, IDE extension and ChatGPT desktop app, which share one config. Codex Cloud tasks and ChatGPT on the web use installed plugins and don't read that config. ### Is StalkChain free? Connecting is free and needs no card. Free tools, like the live feed sample, work right away. Most research lookups are paid; the plans are listed on data.stalkchain.com. ### Which chains and data sources are covered? Robinhood Chain, Solana, Base, BNB Chain, Ethereum, Monad and Hyperliquid perps. Trader data comes from FOMO, launch data from StonkFun, plus Jupiter. Deployer and sniper checks are Solana-only; wallet age and funding checks are EVM-only. ### How far back does the data go? From the last hour back to all-time. Codex can pull PnL for 24h, 7d, 30d or all-time, fill-by-fill trade history, past prices, a deployer's earlier launches and DeFi exploit records. ### Can Codex alert me when a KOL buys? Yes. Ask Codex to set a StalkChain alert: when a token crosses a price, or when two or more tracked traders buy it within a few minutes. It fires once, by email or to a Discord, Slack or Telegram webhook, and works on Solana, Ethereum, Base and BNB Chain. ### Is it safe? Does it touch my wallet? It never touches your wallet. The research tools work on public data, and connecting never asks for a seed phrase, private key or signature. You sign in with OAuth and can disconnect any time. ### Is this financial advice or a signals service? No. StalkChain gives Codex data, not signals: who bought, what they hold, what they sold and when. What you do with it is your call. ## Let Codex pull the receipts FOMO and more, live and historical, in the chat you already use. Free to connect. Not financial advice. - Connect: https://data.stalkchain.com/mcp - Start free: https://data.stalkchain.com/?utm_source=stalkchain&utm_medium=ai-page&utm_campaign=codex - Product docs for agents: https://data.stalkchain.com/llms.txt - This page: https://stalkchain.com/ai/codex
