Where the data comes from
| Source | What it gives |
|---|
| PumpPortal’s public feed | Every new pump.fun coin the moment it’s created: its address, name, ticker, the wallet that created it, and what that wallet bought in the create. (Coin pictures come from pump.fun’s own picture server.) |
| Solana itself (RPC) | The create’s block and the next two blocks (who bought, how much, who funded them), every wallet’s balance, the bonding curve, the mint and freeze settings. |
| DexScreener | Price, market cap, volume, buys and sells. |
| RugCheck | Holder count, the top 10 share, and wallets it links into insider networks. |
| Drop’s launch record | Every pump.fun launch since 17 Oct 2026: which wallet launched it and whether it graduated. It grows every day. |
Drop’s reader runs on our own small server. It only reads: it never trades, never signs, holds no keys to money, and needs no wallet from you.
The nine checks
Bundle 31%
Bundle
Wallets other than the dev whose buys landed in the same block as the create. Shown as their share of the 1 billion supply. Strangers almost never land in the creation block by chance; it usually takes a bundle sent together with the create.
1% to 5% note · 5% to 15% warning · 15% or more risk
Snipers 7
Snipers
Wallets that bought in the next two blocks after the create (under a second), and how much they took.
3+ wallets or 5%+ warning · 8+ wallets or 15%+ risk
Dev-funded buyers 3
Dev-funded buyers
Early buyers whose SOL came from the dev wallet, or from the wallet that funded the dev. One person buying from several wallets to look like a crowd.
any risk
Dev sold 60%
Dev sold
The dev wallet’s balance of the coin, watched live (a subscription to its token account, with a regular check as a backup). Measured against the most the dev ever held, so buying more and selling it later still counts.
10% to 50% trimmed, warning · 50% or more sold, risk · alerts at 10%, 50% and 95%
The dev is the wallet that signed the create and made the first buy. Some launch platforms put their own program address in a coin’s “creator” field; Drop follows the signing wallet instead.
Big dev buy 12%
Big dev buy
What the dev bought in the create itself, as a share of the supply. A big dev bag is a big seller later.
8% to 15% warning · 15% or more risk
Bundle sold 90%
Bundle sold
The launch-block wallets have sold most of what they got. Only flagged when the bundle held a real share; a 2% bundle taking profit is ordinary.
bundle 5% to 15% warning · bundle 15%+ risk
Serial dev 194
Dev record
Every coin this wallet launched since 17 Oct 2026: how many graduated, how many died (6 hours without graduating), how many are still young, and how many in the last 24 hours.
5+ coins, none graduated serial dev, risk · 1 in 5 graduated track record
Top 10 hold 41%
Top 10 holders
What the ten biggest wallets hold, with the bonding curve and pools left out.
35% to 50% warning · 50% or more risk
Mint open yes
Mint and freeze
Whether more of the coin can still be made (mint authority), or holders’ wallets frozen (freeze authority). pump.fun coins have both closed; a coin with either open isn’t a normal pump.fun coin.
either open risk
How alerts work
Star a coin and allow alerts once. Your browser gives us a push address from its own push service (Google, Mozilla, Apple or Microsoft). We keep that address and the coins you starred, nothing else: no name, no email, no wallet. When the dev’s bag of a starred coin drops past 10%, 50% or 95%, the reader sends one alert, encrypted for your browser only. Each coin is watched for 14 days; up to 50 coins at a time.
Turn alerts off in the terminal (the bell), or in your browser’s site settings. A push address that stops working is deleted.
