One number for how launches look today.
The share of new pump.fun launches that showed a bundle pattern in their first seconds on-chain. Measured on a sample SOLVET cannot choose, sealed every hour, checkable by anyone.

HOURLY · LAST 7 DAYS
An hour with fewer than 10 checked coins stays empty instead of showing a guess.
What the number counts
A pattern, read from the chain
A launch counts when any of these is true in its first seconds: buyers inside the creation transaction, two or more other transactions in the launch block, or six or more in the first three blocks. Nothing else. No opinion, no score.
A sample nobody picks
A coin is in the sample if the first 8 hex digits of sha256(address), as a number, mod 1000, are below 200. Sampled coins are always checked first, so the number is not pushed up by coins that look suspicious. Bot and launch-service wallets (40+ launches a day) are left out.
Is your coin in the sample?
Paste any address. Your browser does the maths, SOLVET is not asked.
Every hour is sealed
Ninety minutes after an hour ends, SOLVET hashes that hour’s counts and puts the fingerprint into the public hourly SOLVET Proof. Pick an hour and your browser recomputes the fingerprint and the seal’s Merkle root.

What the Index does not say
Not that a coin is good or bad
A launch pattern is a fact about the first seconds. It is not a verdict on a coin and not advice. Many coins with the pattern are never touched again; many without it are.
Only new pump.fun launches
Other launchpads and older coins are not counted. If the stream is down for part of an hour, that hour shows fewer launches. Its coverage figure stays printed.
Not a long history yet
The first reading was sealed when SOLVET started the Index. “Usual” is the mean of the previous 7 days and needs at least 3 days of readings.
No number is better than a guess
With fewer than 40 checked sampled coins, or less than half of the sample checked, SOLVET shows no number and says why.
