Case BZ-0000 · classified · opened today
Who bought in the block the coin was born?
Blockzero reads a token's first transactions straight from Solana mainnet and reconstructs its first block. Who bought next to the creation, how much of the supply the first slots took, what the creator still holds, and whether the terms are fair. Evidence, not vibes.
Or pick a fresh launch from the intake desk below.
Intake desk
Launchpad coins trending on Jupiter in the last hour and created within the past three days, plus any coins held by your connected wallet. Pick one to open a case. Top-holder share is Jupiter's own figure, printed as a second opinion beside ours.

Connect a wallet to list the coins you hold, then audit any of them.
Open a case above. A full audit reads up to 10 pages of signatures and 25 transactions, four at a time.
The creation block
Every transaction that landed in the same slot as the one that created the mint, in block order. The creator's own buy is shown separately from anyone else's. On a fair launch the second list is empty.

The block will be laid out here.
How a block is read
- A slot is a 400 ms window. The leader packs transactions into one block.
- Order is recorded. Every transaction has an index; the create comes first.
- Balances tell the story. Pre and post token balances show who received the new token.
- Same slot, same moment. A buy beside the create was prepared before anyone else could see the coin.
- The redaction lifts. Those wallets are named in Exhibit A.
Sniper share in the first slots

Fair-terms checklist score
Eight terms, each read from the chain, each worth a published number of points. Untick a line if it does not apply to this kind of coin and the score is recomputed without it.

How the audit is done
- §1
Walk back
getSignaturesForAddresson the mint, 1,000 at a time, until the oldest page. Ten pages at most; busy coins past that are reported as "creation out of reach". - §2
Open the first 25
The earliest signatures are fetched with
getTransaction, four at a time, and sorted by slot and in-block index. - §3
Diff balances
For each transaction, post minus pre token balance per owner. The owner left holding the largest balance after the create is treated as the curve or pool and excluded.
- §4
Read terms
Mint account (authorities, Token-2022 extensions), supply, the twenty largest accounts and their owners.
- §5
Score
Points per term, printed beside each line. The report is canonical JSON; its SHA-256 can be filed with one Memo.
Questions for the file
Does a same-block buy prove insider trading?
No. It proves the buy was prepared before the coin was publicly visible, which usually means the creator or someone they told. Bots that watch the creator's wallet can also do it. Blockzero shows the evidence; it does not accuse anyone.
Why can a case say "creation out of reach"?
Very busy coins have hundreds of thousands of signatures. Walking back past ten pages would hammer the shared RPC, so we stop and say so instead of guessing.
Is the score a safety rating?
No. It is a count of fair terms, each read from the chain. A coin can score well and still go to zero. Nothing here is financial advice.
What does "File case on mainnet" do?
It asks your wallet to sign one SPL Memo instruction containing the mint and the SHA-256 of the report. It costs the network fee and moves no funds.
Why do my results differ from Jupiter's figures?
Different method. Jupiter clusters wallets over a coin's whole life; we look only at the first transactions by slot. Both are shown so you can compare.
