The end of block 0s, bundles and vamps. Every rule, with the number.

level launches coins on the real pump.fun bonding curve: same curve, same graduation, same liquidity. What changes is around it: who deploys, what gets block 0, what's allowed to launch, and where the creator fee goes.

You pay

0.035 SOL + the 2% guard

About 0.62 SOL today, shown exactly before you sign

Guard

2% of supply

Bought in the create, sold into snipers

Buyback

50% of fees

Buys the coin back and burns it

Fee sweep

every 5 min

One claim per cycle, all on chain

You sign exactly one thing: a fixed payment to the master. Everything on chain after that is signed by the master.

1. 1PrepareName, ticker and picture go through the vamp check. You get back one unsigned transaction: a transfer to the master for the 0.035 SOL fee plus the exact guard cost at pump.fun's fresh-curve price, and a level:<id> memo.
2. 2SignYour wallet signs it. The server stores a hash of that exact message and rejects anything else.
3. 3ConfirmThe payment is sent. The vamp check runs once more, then the master signs create + guard buy as one transaction.
4. 4Refund on failureIf the create would fail or doesn’t land, the payment goes back to your wallet automatically.
5. 5Founder buy (optional)Built after the guard, never in block 0, and capped so you can't pass 5% of supply on the curve.

Every coin here is created by the same master wallet, so "was this launched on level?" has a yes or no answer. Paste a contract address below, in the search bar at the top of every page (press /), or call /api/search.

With no dev bag, the first buys after a create are free money for bots. So your create and a 2% guard buy are one transaction: they land together, in order, or not at all. The coin address is generated on our server and stays private until it's on chain, so nobody can pre-arm a sniper.

A bundle is a dev buying the launch from a stack of wallets in the same breath as the create. Here, the create is signed by one master wallet that every coin shares, and the only buy inside it is the guard.

Ticker and name are folded to one form: case, spacing, Cyrillic and Greek lookalikes and leetspeak all collapse. That form is compared with every coin launched here, and with launches that are paying right now. A match is refused; on anything 4+ letters, one edit away is refused too. Pictures are compared by a 64-bit perceptual hash, 6 bits or fewer apart counts as the same picture. All of it runs before you pay.

// The exact fold the vamp check uses (lib/vamp.ts).
canon('P3PE')    // 'pepe'   leetspeak
canon('PЕPE')    // 'pepe'   Cyrillic Е
canon('P E P E') // 'pepe'   spacing
canon('LOL')     // 'ioi'    l and i are one glyph

collides('pepe', 'pepes') // true  — one edit, 4+ letters
collides('dog', 'dogs')   // false — too short for the edit rule

The master is every coin's creator on pump, so pump pays the creator fee into a bucket per coin. Every 5 minutes one claim sweeps those buckets. The amount booked is read from the claim transaction itself.

1. 1Sweep + collectEach coin’s bucket is swept and collected by the master in one transaction.
2. 2Split50% is owed back to that coin; the rest funds guards and refunds.
3. 3Buy back + burnOnce a coin's guard has sold and it's owed at least 0.003 SOL, the master buys it and burns the exact tokens in the same transaction.

Every step is on the flywheel ledger with its transaction.

A rank follows the founder's wallet and climbs with each coin that bonds with a clean record.

Only holders can report, once per coin. A report counts after 15 minutes if the wallet still holds, weighted by the smaller of the two balances. 5 holders with 5% of supply between them flag the coin.

Plain JSON over HTTPS on this origin. Reads need no key. Amounts are strings in base units: lamports for SOL (1e9) and 6-decimal base units for tokens. Timestamps are ISO 8601 UTC. Press Run to call the real endpoint.

Errors are { "error": string } with a matching status. A vamp also returns the coin it collides with.

{ "error": "That ticker is taken by $PEPE.", "vamp": { "field": "ticker", "mint": "<mint>", "symbol": "PEPE", "name": "Pepe" } }

• The master wallet is custodial for fees and the guard: it signs creates, guard trades, claims and burns. Every one of them is on chain.
• Founders hold their own keys, so the founder cap is a build rule, not an on-chain one. The holder check shows what they hold.
• The vamp check covers coins launched here. Copies made directly on pump.fun aren’t blocked, but Verify will say they didn’t launch here.
• Pump.fun sets the trading fee and keeps its protocol share. Its takeover (CTO) admin can reassign any pump coin’s creator fees.
• Linked wallets are found one step back. A clean holder check is evidence, not proof.
• Not affiliated with pump.fun.
