- Step 4Metadata goes to ArweaveThe logo, then a metadata JSON pointing at it, uploaded via Irys from your wallet.
- Step 5Sign one transactionThe create, your first buy and the Solstack fee in one transaction. If any part fails, none of it is applied.

The atomic first buy
The create and buy instructions land in the same transaction, so no other buyer can trade between them. The buy comes from one wallet and is visible on-chain as the creator's buy; Solstack does not split buys across wallets.
Set by pump.fun
- Supply is fixed at 1,000,000,000 with 6 decimals.
- Mint and freeze authority are handled by the program; there is nothing to revoke.
- Trading starts on the bonding curve immediately and migrates to an AMM when the curve completes.
- Creator fees on trades accrue to your wallet's creator vault; claim them on pump.fun or from Creator Fees.
Before you start
- Have the name, ticker, a square logo and any links ready. They're written into the coin's metadata and can't be edited after launch.
- Decide the dev buy: how much SOL you'll spend on your own coin in the launch transaction. Zero is allowed.
- Keep the dev buy, the 0.05 SOL fee and a little extra for rent, uploads and network fees in the wallet. The review screen shows the total before you sign.
- Rehearse on devnet if it's your first launch: the program runs there, though pump.fun's site won't list the coin.
What it costs
| Solstack fee | 0.05 SOL per launch. |
|---|---|
| pump.fun trade fee | About 1% of the dev buy, charged by pump.fun. |
| Rent, uploads, network fee | Small amounts for the coin's accounts, the Arweave upload and the transaction, shown before you sign. |
What you sign
Irys funding approvals if needed, then one transaction: create, buy and the Solstack fee.
Troubleshooting
| Simulation fails with a seeds or account error | pump.fun has probably changed its program. Nothing was signed; launch on pump.fun directly until Solstack is updated. |
|---|---|
| Coin doesn't show on pump.fun | You're on devnet. The site only lists mainnet coins. |
| Metadata upload fails | Retry. Arweave gateways occasionally time out, and a failed upload costs nothing. |
| Image shows but socials don't | Socials come from the metadata JSON and can't be edited after creation. |
