Clean
or rigged?
Every launch has a first block. We read it.
Paste any token on Ethereum or Base. First Block finds who bought in the opening blocks, which of them were funded by the same wallet, how much the dev kept, and what the pool's hook can do to your trade. Every claim links to the transaction that proves it.
The board is drawn from the scan: every polaroid is a real early buyer, every red string a shared funder.
The case
How the case is built
Find the pools
Every Uniswap v2, v3 and v4 pool for the token, from the factories' own creation events. For v4 it also reads the pool's hook.
Find the launch
The first real swap (a Swap event, not a liquidity add) by anyone but the deployer. That block is block 0.
Read the opening
Every buy in the first 30 minutes after trading opens (longer if few people bought). Buys in the first 36 seconds are snipes.
Follow the money
For each early buyer, the last ETH that reached it before it bought. Wallets fed by the same address or the same multi-send are linked. Exchanges are ignored.
Score it
Linked supply, block-0 supply, dev buys, pre-launch wallets and hook powers each take points off. The report says why.
Fine print
| Token | $FIRSTBLOCK |
| Contract | TBA |
| Chains | Ethereum mainnet and Base. Pools: Uniswap v2, v3 and v4 everywhere; on Base also Aerodrome and the other pools Dexscreener lists for the token. |
| Data | Public RPCs (Tenderly gateway, MEV Blocker, PublicNode), Blockscout API v2. No keys, no backend, no tracking. |
| What it cannot see | Wallets funded through privacy tools, CEX withdrawals, or long chains of hops look unrelated. A clean report is not a guarantee. A linked wallet is evidence, not a verdict on a person. |
