Launch a coin that's born proven.
Launch a real coin on pump.fun, stamped with Bitcoin proof-of-work before it exists. Your browser makes the mint address, binds it to the latest Bitcoin block by hashing, and writes the stamp into the coin's metadata. Your wallet signs one transaction and the coin goes live on pump.fun's bonding curve.

Why stamp first
The work comes after the address
The stamp hashes the mint address itself, so it can't be mined in advance or copied onto another coin. Anyone can re-hash it from what's in the description.
Your keys
Nothing leaves your browser
The mint keypair and the stamp are made in this tab. The server only uploads your image and asks PumpPortal for an unsigned transaction. It never sees a private key.
Verify any stamp
Check it yourself
sha256d("PROOF-OF-COIN:v1" ‖ bitcoin block ‖ mint ‖ creator ‖ nonce) must have the zeros the stamp claims. The docs have the exact bytes.
