One signature. A coin and its chain.

$
SOL

Your first buy lands in the same transaction as the launch, so no one can snipe it.

About 0.02 SOL in network and pump.fun fees, plus your dev buy. One signature creates the coin, makes your first buy and registers the chain. Creator fees are paid to your wallet.

Chains

No chains yet.

The first launch is block zero of the first chain.

Launch a chain

From launch to block one.

  1. Launch

    Fill in the coin. One wallet signature creates it on pump.fun, makes your first buy and registers the chain, all in a single transaction.

  2. Get a chain

    The coin is assigned a chain ID derived from its address, a network name, an RPC and an explorer page. Block 0 is the launch transaction.

  3. Watch it run

    A new block lands every 2 seconds. Each trade on the bonding curve is placed in a block and linked to its Solana signature.

What is a virtual chain?

A ledger of one coin's Solana activity, cut into 2 second blocks. It has its own chain ID and an RPC you can query.

It is not a separate network. Nothing is bridged and nothing runs validators, so it does not belong in your wallet's network list.

$ curl -s https://pumpchain.wtf/rpc/482133 \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"vnet_blockNumber","params":[]}'

{"jsonrpc":"2.0","id":1,"result":"0xc5"}

Methods: vnet_chainId, vnet_networkInfo, vnet_blockNumber, vnet_getBlock, vnet_getRecentTransactions, vnet_getHolders, vnet_getBalance. Example id shown; every chain has its own.

Questions.

Is this a real blockchain?

No. A Pumpchain chain is a virtual ledger built from your coin's real activity on Solana. Trading happens on pump.fun and settles on Solana. Pumpchain adds a chain ID, an RPC and an explorer on top.

Can I add a chain to my wallet?

No. The RPC answers vnet_* methods only and rejects eth_* calls. It is for reading the ledger, not for sending transactions.

Where does the chain ID come from?

It is derived from the coin's mint address, so there is no counter and nobody can pick or reserve one.

Where do blocks come from?

From the clock. A block is produced every 2 seconds from genesis whether or not anyone trades. Trades on the pump.fun bonding curve are placed in the block of their Solana timestamp. Once a coin graduates to PumpSwap the ledger keeps its blocks but stops listing new trades.

Who earns the creator fees?

You do. The launching wallet is the coin's creator on pump.fun, so creator fees are paid to it directly. Pumpchain takes no fee of its own.

How is a registration verified?

The launch transaction carries a memo signed by your wallet, and Pumpchain checks that the coin's bonding curve names that same wallet as creator. A chain cannot be registered for someone else's coin.
