Follow a wallet
The tape, the watchlist and the Telegram bot: what an address did, read off the chain.
A social trading app lets you follow a trader who has an account there. Most of the money on this chain has no account anywhere, only an address. Collapick follows the address: the tape shows what the busiest wallets are doing right now, the watchlist shows what the ones you picked did today, and the Telegram bot sends you each trade the minute it lands.
The tape
/flow reads the recent trades across the busiest pool of each of the busiest tokens and sums them per wallet. “Buying the most” is dollars spent inside the window. “Taking money off the table” is dollars sold minus dollars bought, which is not profit and is not called profit: a wallet that bought yesterday and sold today shows up here, because today it took money out. One hot pool can print three hundred trades in six minutes, so the tape shows the newest few of each token rather than sixty rows of one coin. Every wallet links to its bag and every token opens in fomo.
How a trade is recognised
A wallet’s day is read from its own Transfer events, grouped by transaction. Money out and a token in is a buy. A token out and money in is a sell. A token out and a different token in is a swap. Anything else is a transfer and is labelled as one, because “sent” is a fact and “sold” would be a guess.
Trades placed from fomo are paid in native ETH, and native ETH leaves no Transfer behind. Those are read from the PoolManager’s Swap event instead: ETH is always currency0 of a v4 pool, so a receipt with swaps and no USDG or WETH transfer is an ETH trade, and the swap’s amount0 is what the wallet paid or received. Anything that does not fit either shape is left as a transfer rather than forced into a trade.
The watchlist
/follow keeps the wallets you follow in your own browser and nowhere else. There is no account and no server copy, because a list of whose money you watch is the one thing on this site that would be a record of a person. Follow from the tape, from a wallet page, or paste an address; the page merges every followed wallet’s day into one feed, newest first.
The bot
The same reads, delivered. The bot needs no account either: a chat and a list of addresses is all it keeps.
| Command | What it does |
|---|---|
| /follow 0x… name | Message me the minute this wallet buys or sells. The name is optional and is what the messages call it. |
| /unfollow 0x… | Stop. |
| /list | Every wallet this chat follows. |
| /tape | The busiest wallets right now, both tables of /flow. |
| /bag 0x… | What an address holds, priced in dollars, and how its day compares with SPY. |
| /recent 0x… | What an address did in the last day. |

An alert is one line of fact and three links: what the wallet did, for how much, then the token in fomo, the wallet’s bag, and the transaction. Transfers with no money leg and trades under twenty dollars are not sent. Each trade is sent to each follower once; a retry never sends it twice. Up to twenty-five wallets per chat.
How soon an alert arrives. Followed wallets are checked at most once a minute, and the check runs off ordinary traffic to the site rather than a clock, so in a quiet hour it may be a few minutes rather than one. The message says when the trade happened, not when it was noticed.
The same data by API
curl -s "https://collapick.tech/api/v1/activity?address=0x1b0b102c5ee767fbc422a9c04c4764d5f2175ac0" curl -s "https://collapick.tech/api/v1/flow" Both are documented on the API page, both answer without a key, and the MCP server offers them as wallet_activity and tape.
