Launch a coin

One signature creates your coin through the Launchkey FOUNDING config on Raydium LaunchLab — your dev buy included. Your wallet signs; this page never sees a key or seed phrase. What you launch is written to your public file at birth.

1 · Connect wallet — your key

No wallet connected

RPC endpoint

If the default endpoint fails (rate limits, 403 errors), paste a custom RPC URL into the field above — e.g. the RPC URL from your Helius dashboard — and tap Apply RPC. The page remembers your endpoint in this browser. Only the hostname is ever shown outside this field.

2 · Your coin

Coin name (1–32 characters) Ticker (2–10 letters or numbers) Description (optional, 500 characters max — it goes in the coin's metadata and its public file)

0/500

Image URL (https — the image your metadata points at) …or pick an image file to preview it

The preview is local only — nothing is uploaded by this page. The launch uses the image URL above, so host the image and paste its https URL before you sign.

Website (optional, https) X / Twitter (optional, https link)

3 · Your dev buy + lock

Dev buy (SOL) — bought in the same transaction as the launch

Percentages are estimates from the standard curve (30 SOL virtual reserve). The fill the chain records is what your file prints.

Lock the dev buy for 7 days (default on). This is a launch commitment printed on your public file: right after the launch confirms, you place the lock as a separate step from the same wallet. A lock claim without the lock is a file entry too.

4 · Pairing

SOL — standard BTC — later ETH — later Stablecoins — later Tokenized stocks — later

Every key pairs SOL at launch today. The wider catalog opens by grade as the doors are built — a chip marked “later” is not a button.

5 · Your public file, as the world will see it

Fees, printed plainly — charged on trades, not on the launch itself:

Platform fee — FOUNDING config: 0.5%

Creator fee — to the launching key: 0.5%

Raydium protocol fee: 0.25%

Total: 1.25%

Founding Key Terms: keys that launch through the FOUNDING config pay the 0.5% platform rate for the life of the service.

Metadata URI (https — this exact JSON must be live at this address when you launch; it is written into the coin's on-chain metadata)

Metadata JSON — the document that URI must serve

Safety

No keys, ever. If anything — a page, a popup, a person — asks for a seed phrase or private key, it is a scam. This page only asks your wallet to sign.

Review before you sign. The launch parameters are printed in the log and in your wallet's approval screen. The mint address is generated in this tab at launch time and shown before anything is sent — record it even if the send fails.

Your file is a record, not a promise. It prints what the chain shows: your key, your grade at launch, your buy, your lock commitment, and your moves after. Grades summarize a wallet's observed record under the published rules.
