Launch on Solana.
Carve it into Bitcoin.
Pick the chain your coin belongs to. The moment it goes live, its ticker and contract are written into a block on that chain, permanently. Its address ends in that chain's letters, so anyone can tell at a glance.

Launch a coin
One signature in Phantom. The chain you pick keeps the record.
Carvings
Every coin launched here, and the block that holds it.
How it works
Pick a chain, then a name, ticker and image. Sign once. The coin is created on pump.fun with you as creator, and its address ends in that chain's letters.
It trades on pump.fun's curve like any other coin and graduates to a Solana DEX when the curve fills. One billion supply, fixed.
CARV writes the launch into the chain you picked. Once it's in a block, it stays there for as long as that chain exists.
Docs
What exactly gets written, and where?
The text CARV <TICKER> <contract address>, written into the one chain you picked. On Bitcoin it's an OP_RETURN output. On EVM chains it's the data of a small transaction. Anyone can read it on mempool.space or the chain's explorer, and your coin page links straight to it.
Who pays for the carving?
CARV does, from its own wallet on that chain. It's covered by the 0.01 SOL launch fee. You don't need BTC, ETH or anything else.
How long until my coin is carved?
The carving goes out within a minute of your launch fee landing. EVM chains confirm in seconds. Bitcoin mines a block about every 10 minutes. If fees spike, the carving waits for them to settle.
Why does my address end in BTC, ETH or hood?
Your coin's mint address is generated in advance so it ends in your chain's letters. Some endings are lowercase, like hood for Robinhood Chain, because a capital O can't appear in a Solana address.
Is my coin on that chain? Can I trade it there?
No. Your coin lives and trades on Solana. The chain you picked holds a permanent record of its launch: name, ticker and contract, stamped with a block number.
Fees
0.01 SOL to CARV per launch, paid as its own small transfer after your launch confirms. You also pay pump.fun's creation cost, Solana network fees and any first buy you choose.
Risks
Memecoins are extremely volatile and most go to zero. Anyone can launch anything. Transactions on every chain are final. CARV is not affiliated with pump.fun or any chain it writes to, and nothing here is financial advice.
