How 1 works

1 is a Solana memecoin launchpad with one rule: one name, one ticker, one identity — forever.

The rule

A name can only be launched once on 1. A ticker can only be launched once on 1.
They become permanently reserved only when the coin's mint is confirmed on Solana.
When you continue to payment, the name and ticker are held for your launch for 30 minutes. If you don't pay, or the launch fails before anything reaches Solana, they're released.
If a launch transaction was sent but its outcome is unclear, the hold stays until recovery confirms whether a coin exists — so nobody else can take it in the meantime.
This is enforced by the database with unique constraints, not just by the website. Two people racing for the same name: exactly one wins.
Uniqueness applies within 1 only. Other launchpads may use the same names.

Normalization (exact rules)

Ticker: Unicode NFKC, trim, remove a leading $, uppercase. Valid: A–Z and 0–9, 1–10 characters. $moon, MOON and Moon are the same ticker.

Name: Unicode NFKC, lowercase, look-alikes folded (0→o, 1→l, 5→s, $→s, @→a), then every character except a–z0–9 removed. Valid: 2–32 characters after that. Moon Cat, moon-cat and M00N CAT are the same name. The name shown on your coin keeps your original spelling.

Launching

Upload an image, pick a name and ticker (live availability), add optional description and links, and an optional dev buy.
Review the exact costs, then hold your name and ticker and get a fresh payment address for this launch only.
Send the SOL shown. Payment is detected on-chain; the launch on pump.fun starts automatically.
When the mint is confirmed, the name and ticker are claimed forever and the coin page goes live.

Refreshing, double-clicking or retrying reuses the same launch session — you can't be charged twice or create two coins from one payment.

Costs

1 platform fee: 0 SOL today.
Launch price: a flat 0.05 SOL covers pump.fun creation, Solana rent and network fees (third-party costs), plus the standard 0.001 SOL first buy. Any unused buffer stays with 1's launch infrastructure.
Optional dev buy: goes to the pump.fun bonding curve, and the coins go to your wallet.

$1 buy & burn

Coins launched on 1 route their pump.fun creator fees to 1. 100% of the fees 1's treasury actually receives from those coins are used to buy the main $1 token and burn it, in 10-minute cycles. Trading fees kept by pump.fun, Solana or anyone else are not included.

Each cycle: sum finalized eligible fees not yet used → check them against the real treasury balance (keeping a small reserve for network fees) → quote a swap with a slippage cap and minimum output, skipping if liquidity is thin → persist, broadcast and confirm the swap → burn exactly the $1 bought with an irreversible SPL burn → confirm, check supply dropped → record amounts and signatures. A window can never be spent or burned twice; interrupted cycles resume.

Accounting: eligible fees received = fees waiting to be used + SOL used in buys. Network fees come from the treasury reserve, not from eligible fees.

The canonical $1 mint is set by an admin, and every change is recorded in an audit log. It is never guessed from a ticker or name. Until the mint, treasury and a tested execution path are in place, the Burns page says Not live, and no burns are shown or simulated.

Legacy coins

Coins from earlier products on this infrastructure still have their pages and records, and anything still owed on them is kept. They aren't listed, counted or covered by the one-name rule.

Risks

Memecoins are speculative and can go to zero. Nothing here is a share, security or promise of returns. Solana transfers are final. See Risks.
