Base data in Grok, in short

Setup: Custom connector, sign in once. No API key needed.
Connection: One MCP link for every chain and source: https://data.stalkchain.com/mcp
Coverage: Base (chain id 8453) is one of the 7 chains. Every FOMO tracked-trader tool, every cross-chain wallet and price tool, the DeFi tools, alerts and the agent wallet work on Base.
Data: Tracked traders' Base positions, fills, bags and PnL. Per token: tracked holders, dev and insider bags, buy/sell flow, theses. Any 0x wallet: holdings, transfers, age. Token prices, metadata and history.
History: Fills and positions page back months, one token at a time. Price history by day, hour or 5 minutes. The alerts feed pages back by cursor. Holder history comes from snapshots the agent keeps and diffs.
Freshness: Buys and sells reach the feed within seconds and the live stream can be sampled for up to 120 seconds. Boards and leaderboards cache 5 minutes. Alerts are checked about every 5 minutes.
Address format: 0x plus 40 hex characters for wallets and tokens. Chain is spelled base (or 8453) on FOMO tools, base on wallet and price tools, and network base on theses by token.
Upstream: FOMO (fomo.family) for tracked traders, theses and the alert feed. A multi-chain node and price provider for wallets, transfers, metadata and prices. DefiLlama for TVL, yields and exploits.
Best for: Seeing which Base tokens tracked traders are entering, who holds a Base token and whether they are selling, and sizing up a 0x wallet that just aped.
Not covered: Deployer history, sniper and bundler checks, on-chain PnL for a raw wallet, exit quotes, wash-trade scores and the milestone study are Solana-only. StonkFun is a Solana launchpad. Candles are gated to higher FOMO data tiers.

Know before you ask

What should Grok know about Base data?

Spell the chain: Pass chain: "base" (or 8453) to the FOMO tools, chain: "base" to wallet and price tools, and network: "base" to stalkchain_fomo_theses_for_token. Alerts need chain: "base" too: a 0x token with no chain defaults to Ethereum.
Buy sizes: On a buy alert, usdValue is the position's mark after the fill, not the fill size. Use tradeUsd when present, or stalkchain_fomo_trade_detail (swaps[].humanUsdAmountIn) for the real buy size.
Feed coverage: One alerts page is 100 items. Filtered to Base buys it covered about 23 hours today; unfiltered it covers roughly 10 minutes. Narrow by chain and type, and page with cursor for exactly-once resume.
PnL on Base: PnL exists for tracked FOMO traders (positions, swaps, leaderboard). There is no on-chain PnL tool for a raw Base wallet: for an unknown 0x address use portfolio, transfers and age.
Tokens outside the directory: Stats, devs and analysis need chain: "base" for tokens FOMO has not indexed, or the upstream returns 400. An empty devs list means no known dev holding, not that the token is safe.

FAQ

Base data in Grok: questions

Add StalkChain to Grok (custom connector, sign in once), then ask a Base question in plain words. It takes about a minute and needs no API key. The same connection covers every other chain and source too.

Yes. The multi-trader entries tool groups the Base buy feed by token and counts distinct tracked traders, so one call answers which tokens three or more of them entered in a window. Today it returned EDEL with 14 traders and STONKEX with 6. Pass chain base so the 100-alert page covers hours instead of minutes.

Not on Base. Deployer history, early buyers, bundler share, exit quotes and wash-trade scores are Solana-only tools. On Base you get the deployer's and insiders' own positions from FOMO, the age and funding transfers of any suspicious 0x wallet, and the token's metadata and price.

For tracked FOMO traders, yes: positions with entry and exit prices, fill-by-fill swaps, and PnL over 24h, 7d, 30d and all time. For a random 0x address there is no on-chain PnL tool on Base. You can still see what it holds, what it moved and when it was first active.

Yes. Three kinds: price above, price below, and smart-money buy, which fires when at least N tracked traders buy the token. Delivery is email or your own Discord, Slack or Telegram webhook. Alerts fire once, are checked about every 5 minutes, and you can keep 20 active.

It can trade if you switch trading on. Your agent gets one EVM wallet that works on Base, funded in ETH, and can buy or sell a token as a single swap within the per-trade and daily limits you set. It only trades when you ask in the conversation, never because a thesis or token page said to.

Those show one wallet or one pair per tab, with no idea who the trader is. StalkChain resolves FOMO handles to their real wallets and brings their Base positions, fills and theses into the chat, next to per-token holders, flow and any 0x wallet's holdings. One question instead of five tabs.

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.
