A sample from the Single Buys lane on Solana, recorded by Early Bird Calls on 2026-09-23. The live board above keeps updating; this log does not.
Recorded values, not live prices. Charts open on GMGN with the publisher's referral code.
A Single Buys alert means one tracked wallet bought the token.
Put simply, a buy is a fact. The reason behind it is a guess. Early Bird Calls uses the Single Buys channel for the facts and keeps the guessing for later.
Put simply, wallet alerts show what money did, which is harder to fake than a post. Early Bird Calls follows Single Buys on Solana and asks whose wallets they are and what they did before.
One habit: Check whether several buying wallets were funded from one source a few minutes earlier. Open the buying wallet and read its last twenty trades before trusting the buy.
| Token | Chain | First alert cap | Tracked cap | Multiple | Report |
|---|---|---|---|---|---|
| S3 | SOL | $87K | $6000K | 70x | 2026-09-08 |
| MAGNET | SOL | $42K | $846K | 20x | 2026-09-10 |
| fone | SOL | $44K | $23800K | 538x | 2026-08-30 |
| Frug | SOL | $29K | $551K | 19x | 2026-08-26 |
Selected dated examples from XTRACK reports: multiple = tracked market cap at the report date divided by the market cap at first alert. These are not typical results and not realised profits.
Telegram is where every Single Buys alert lands first. These are the verified routes for Early Bird Calls.
Run these on every contract, in this order.
Filters are a choice, not a truth. This is the choice Early Bird Calls made for Single Buys alerts:
At build time the lane held 47 recent alerts covering about 1 hours; 0 of them cleared the screen. 9 out of 47 alerts showed a pool smaller than a tenth of the cap — a warning sign on its own. Median concentration in the lane: 21 % of supply in the top ten wallets.
None of the recent alerts passed at build time, so the board may show a wider view until new alerts qualify.
Values measured on 2026-09-23 from the Empire feed. The screen is a filter, not a recommendation.
Over the last 7 mature days the network alerted 1301 tokens in Single Buys on Solana. 20 % reached 2x within 24 hours and 7 % reached 5x; 53 % died inside a day, usually after about 4.9 h. The Solana average for all topics was 25 % reaching 2x. With 95 % confidence this lane did worse than the rest of Solana on the 2x measure, which is why the checks matter more here.

It is one of the Empire's public desks. It watches Single Buys alerts on Solana, prints them live and explains how to check each one.
An alert means the token matched a filter. Trust comes only from your own checks.
In the last 7 measured days, 20 % of Single Buys alerts on Solana reached 2x within 24 hours (1301 tokens). The same share can be very different next week.
No. Alerts are observations from public data. Every token here can lose all of its value, and you decide what to do with the information.
