A live 3D city for the trenches.

City Hall: one window per citizen

City Hall, the tower in the plaza, is $PUMPCITY's building. Its height follows $PUMPCITY's market cap on the same scale as every other building. Its windows are the citizens, and together they make up the Citizenship Roll.

• A wallet gets a window with its first $PUMPCITY buy. Windows are ordered by first buy, so window #1 bought first. The order never changes.
• Labels are computed from $PUMPCITY trades only, using public on-chain data. The server is the source of truth.
• Labels depend on time, so the server re-checks every wallet every 5 seconds and sends only the changes.
• Use My window in the city to paste any address, or your connected wallet, and see its label, rank, first buy and SOL in and out.

Labels

t0 is the coin's creation time, its first trade. The first rule that matches wins.

Edge cases

• A wallet that only sells (its tokens arrived by transfer) counts as JEET at its first sell.
• Snipers: hold 30 minutes and you're an Old Timer. Sell inside ten minutes and you're a Jeet like anyone else.
• Labels are a game played on public trades. They aren't a judgement of anyone, and they say nothing about what a coin is worth.

Roll calls

At fixed moments City Hall takes the roll: the server counts every label, and every window flips to its label at once with a flash. Each roll call goes into the City pulse.

At the 30-minute and one-hour roll calls the city also names the Jeet of the Half Hour and the Jeet of the Hour: the largest single sell, in SOL, by a JEET in that window, with its transaction.

Jeet Alley

Every JEET sell goes on the Alley billboards and into the Jeet Alley list in the city, with a Solscan link to the transaction. Big jeet sells also go into the City pulse.

Bonding Curve Boulevard and the Graduation Gate

The main avenue runs from the plaza to the city's entrance. It's Bonding Curve Boulevard, and its road glows like a progress bar from the gate toward City Hall: the fill is $PUMPCITY's bonding-curve progress on pump.fun, from 0 to 100%.

At the end of the boulevard stands the Graduation Gate. It stays shut, bars glowing, until $PUMPCITY graduates. At graduation the bars slide up, fireworks go off, a light wave runs up the boulevard to City Hall, and then City Hall takes the graduation roll. The gate stays open after that.

Live Stage

A wall of six screens in a corner of the plaza shows the six biggest pump.fun livestreams right now, ranked by viewers and then market cap: thumbnail, ticker, market cap and how many are watching. It refreshes every 30 seconds. Tap a screen, or open Live Stage in the toolbar, to watch it on pump.fun.

Streams flagged NSFW or banned by pump.fun are left out. Showing a stream is not an endorsement of the stream or its coin.

Graduation fireworks

Whenever any coin graduates on pump.fun, a firework with its ticker bursts over Old Town, and the City pulse says so. The pulse also counts how many coins graduated on pump.fun tonight.

Rug Row: bury a coin

The edge of Old Town is Rug Row, the city's graveyard. Anyone can paste a pump.fun coin's address into Rug Row in the toolbar. If the coin is dead, it gets a tombstone with its name, ticker, picture, all-time-high market cap, when it peaked and when it died.

• Dead means its market cap is at most 10% of its all-time high and nobody has traded it for 30 minutes, or nobody has traded it for 6 hours.
• A coin that's still trading is turned away: Still alive: can't bury a coin that's breathing.
• One burial every 30 seconds per visitor, and Rug Row holds 300 graves. Each coin can be buried once.
• Grave #1 is $BRICK's haunted tower, the dev's last coin.

Dev Watchtower

A slim tower next to City Hall watches every wallet tagged DEV. Its beacon is green while none of them has sold $PUMPCITY and turns red, for good, the moment one does. Any sell by a DEV-tagged wallet counts. The header's Dev watch chip shows the same thing, and opening it lists every DEV sell with its transaction.

Build a building

Every lot launches a real pump.fun coin, and its building rises and falls with that coin's market cap.

1. Pick an empty lot. Click Build, then any glowing lot. Skyline Row faces the plaza, Downtown rings it, and The Trenches are everywhere else: their lots are foxholes.
2. Name your coin. Name (up to 32 plain letters; fewer with emoji), ticker (up to 10 letters or numbers), a picture, optional links, and an optional first buy in SOL.
3. Approve in your wallet. Batch-signing wallets use one approval for both transactions: the lot's toll, then the coin's creation on pump.fun, your first buy, and the locked fee split. Other wallets ask twice, before either transaction is sent.
4. It goes up. The city checks on-chain that the coin exists and the split is locked, then your building breaks ground. From then on it follows the market cap: 1 storey up to $4K, then 2 more every time the market cap doubles, up to 60.

Lots & tolls

The city has 1,260 lots on a 12 × 12 grid of blocks. Where you build sets the toll. The toll buys $PUMPCITY and burns it in the same approval as your launch. The city never holds it.

One lot holds one coin, forever. Buildings are never evicted or resold. Toll prices are SOL quotes, with up to 5% slippage. Besides the toll you pay Solana's account rent and network fees, plus whatever first buy you choose. If the toll confirms but creation fails, retry the same lot: your paid toll stays credited and your lot stays reserved.

Skyline Row: residents only

The 24 lots facing the plaza can only be launched by a wallet whose label on the Citizenship Roll is OLD TIMER or DEV, and which still holds $PUMPCITY on-chain at launch time. The server checks both before it reserves the lot. If you don't qualify yet, the launch stops before anything is signed and the panel says:

The rule switches on once $PUMPCITY is live. Downtown and The Trenches are open to everyone.

Creator rewards on city coins: 80% to you

Every trade on a pump.fun coin pays a small fee, and part of it goes to the coin's creator. For every coin launched from a city lot, that creator reward is split:

Locked at launch

The split is set with pump.fun's own fee-sharing program in the same transaction that creates your coin, and it's locked right away. Nobody can change it afterwards, not you and not us.

Hourly payouts

Rewards collect in the coin's vault. Every hour, vaults holding at least 0.01 SOL pay out: 80% to the launcher and 20% to the city wallet, straight into the wallets. You don't have to claim anything. Payouts can be delayed if the city's gas wallet or RPC is unavailable.

$PUMPCITY

• $PUMPCITY is the city's coin, launched on pump.fun. Its building is City Hall, in the plaza.
• Every city launch pays a lot toll that buys $PUMPCITY and burns it. Burns are linked in the City pulse with their transactions.
• The dev wallet is tagged DEV on the Citizenship Roll, live, and the Dev Watchtower shows whether it has sold.
• Same builder as Build the City. $BRICK's tower stands in this city, haunted: the dev's last coin and grave #1 in Rug Row.

Verify it yourself

Everything the city does happens on Solana, through pump.fun's programs.

1. Copy a coin's contract address from its card and open it on Solscan. Its creation transaction contains pump.fun's create, the fee-sharing config and the locked update, all in one.
2. The fee-sharing config is owned by pump.fun's fee program, lists the launcher at 80% and the city wallet at 20%, and is locked.
3. Any window's label can be checked against that wallet's $PUMPCITY trades on Solscan or pump.fun. Jeet Alley and the pulse link the sell transactions.

The city never holds your SOL or your tokens. Your wallet signs every transaction, and the site shows what it asks you to approve.

Risks, plainly

• Memecoins are extremely volatile. Most go to zero. Nothing here is financial advice.
• Labels read public trades with a few seconds of delay. Data sources can lag or pause, and a label can be briefly wrong until the next check.
• An OLD TIMER label opens Skyline Row. It doesn't make anything safe or valuable.
• Trading can start immediately, including from bots. Trading activity and creator rewards are not guaranteed.
• Locked means locked for us and for the launcher. pump.fun keeps admin powers over its own programs.
• Being in Old Town, on the Live Stage or in Rug Row doesn't mean a coin's team endorses the city, or that the city endorses the coin.
• A grave in Rug Row is a game read from public trades, not a verdict on anyone. Dead coins sometimes come back.
