The screen
Every coin page on Corium, for Corium coins and pump.fun coins alike, carries a screen: the signals a trader checks before buying, read from the chain and public sources, so you don't have to leave to check.
What it reads
| Signal | What it is | Where it comes from |
|---|---|---|
| Bundlers | Wallets that bought together in one block: anyone but the creator in the coin's launch block (only a bundle lands there), or three or more wallets in any one block of the first minute, which is where a bundle sent a few seconds after the creation lands. Shown as what they bought and what they still hold: red goes by what they hold now, and a bundle that bought a share worth flagging is amber at least, whatever it holds now. | The coin's first minute of trades, read once and kept |
| Snipers | Wallets that bought within about two seconds of the launch block. | The same |
| Top 10 | The ten largest holders' share of the supply, with pools and exchanges left out. | Jupiter |
| Dev | The creator's share now, what the creator bought at launch, and whether the creator has sold out. | Jupiter and the launch block |
| Insiders | Among the largest holders, wallets whose first SOL came from the same wallet, directly or through one wallet in between, grouped, and what they hold together. A group funded by the creator is marked. Exchanges and bots, which fund thousands of unrelated wallets, never group anyone. RugCheck's own read, which links wallets by token transfers, is shown alongside, and the flag goes by the worse of the two. | Corium's trace of each holder's first transactions, and RugCheck |
| Fresh wallets | Top holders whose first transaction is from the day of the launch or later: wallets made for this coin. | The same trace |
| Creator | How many coins the creator launched, how many graduated, and whether the creator has rugged a token before. | Jupiter and RugCheck |
| Authorities | Whether the mint and freeze authorities are revoked. If not, more tokens can be printed, or wallets frozen. | Jupiter |
| Organic | Jupiter's estimate of how much of the volume is organic. | Jupiter |
Each signal is green, amber or red against fixed thresholds, and the verdict at the head of the screen is the worst of them.
| Signal | Amber from | Red from |
|---|---|---|
| Bundlers' holdings | 8% of supply | 20% |
| Snipers' holdings | 6% | 15% |
| Top 10 share | 30% | 50% |
| Dev's share | 4% | 10% |
| Insiders' holdings | 8% | 20% |
| Fresh wallets' holdings | 10% | 25% |
| Creator | 20+ coins launched and under 10% graduated | Has rugged before |
| Authorities | Mint or freeze not revoked | |
| Organic | Jupiter rates it low |
A creator who bought at launch and has sold almost all of it is amber under Dev.
Where you see it
- The coin page. The strip under the chart. Open Details for every signal's figure and the wallets the launch block names.
- Holder and trade lists. Wallets the screen knows are labelled: Bundle, Sniper, Insider, Fresh, Dev.
- Before a buy. On a coin rated red, Corium shows the red flags first. You decide; nothing is blocked.
- The pump.fun list on Bounties shows each coin's verdict as a dot, and can hide red-rated coins.
- Cori reads the same screen when you ask her about a coin.
What Corium does with it
- The free bounty that a final-stretch buy unlocks is not offered on coins the screen rates red. Corium's own SOL stays off them.
- Corium's X account does not post coins the screen rates red.
What it is not
The screen shows signals, not a verdict on anyone and not a guarantee. Tracing the holders' funding takes a few seconds the first time a coin is opened; a holder seen before costs nothing, and what wasn't reached in time is read on the next look. A label is a fact about a wallet's trades ("bought together in one block at launch"), never an accusation. A green screen does not mean a coin is safe: it means these particular signals are clear right now. Sources can be slow or down; a missing one is shown as unavailable, and the last good read stands meanwhile. Nothing here is financial advice.
