Launch on pump.fun. Your coin boots its own layer 1 and is its gas. Every block gets two post‑quantum seals.

From a coin to its own chain, in one launch.

Name it
Pick a name, a ticker and an image. Your Solana wallet signs once. That is the whole form.

Two things go live
Your coin goes live on pump.fun. At the same time, a new layer 1 starts and makes its first block.

Bridge in, spend as gas
Holders move the coin onto the chain 1:1. On the chain, the coin pays for every transaction. A faucet pays for your first one.
Two seals on every block. Check em.
sample blocksTwo families of math. If one breaks, the other still holds. One operator, two signatures. The bytes shown here are a sample.
Post-quantum
- Every transaction on your chain, ML-DSA-65
- Every block your chain makes, ML-DSA-65
- A hash-based SLH-DSA seal in every block
Not post-quantum
- The coin on Solana
- The bridge between Solana and your chain
- Your Solana wallet
These use the same signatures as all of Solana. We say it here so nobody has to guess.
Private from the public. Not from the operator.
Fixed sizes
A private transfer moves one of four set amounts: 100, 1,000, 10,000 or 100,000. Everyone in the pool looks the same, so nobody outside can match who paid whom.
Sealed for later, too
Private notes are sealed with NIST post-quantum encryption. Notes copied today stay closed when quantum computers arrive.
What the team still sees
The team that runs the chain can see who paid whom, plus every deposit from Solana and the time of each transfer. We say it here because it is true.
Only if you choose it
The creator turns it on for the chain, then you choose it per transfer. Until a size has 20 deposits, the page tells you the pool is not big enough yet.
Private transfers are not live yet. They come after an independent review.

Questions.
Is my coin post-quantum?
No. The coin lives on Solana and uses Solana signatures. The chain we start for it signs its transactions with ML-DSA-65 and seals every block twice. The bridge between the two is not post-quantum.
What are the two seals?
Every block is double-sealed. The validator signs it with ML-DSA-65, a lattice signature (3,309 bytes). Each block also carries an SLH-DSA signature, a hash-based one (17,088 bytes), over the chain state after the block before it. It is one operator with two signatures, not two validators.
What does "the coin is the gas" mean?
On your chain, every transaction is paid in your coin. To use the chain, people bridge the coin from Solana, 1:1. The bridged amount stays locked on Solana until it comes back.
What does it cost?
0.1 SOL to launch. Bridging costs 0.5% in each direction. The pump.fun creator fee is shared: half goes to you, automatically, with a public log of every payment.
What is on the chain on day one?
A faucet that pays for your first transaction, transfers in public or in private, and a chain page where your browser checks both signatures of every block. A launchpad for tokens on your chain comes later.
Are transfers private?
Only if you choose it. Private transfers use fixed sizes, so nobody outside can match who paid whom. The team that runs the chain can still see it.
Who runs the chain?
We do. Each chain has one validator, and that validator is us. It is fast and cheap, and it is centralized. We say it up front.
What happens if nobody uses my chain?
Bridged coins can always come back to Solana, 1:1. We publish the exact rule for quiet chains before launch.
