The skyline is the chart.

Build a building

1. Pick an empty lot. Click Build, then any glowing lot. Skyline Row faces the plaza, Downtown rings it, the Outer city is everywhere else.
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. We check on-chain that the coin exists and the split is locked, then your building breaks ground. From then on it follows the market cap.

Lots & tolls

The city has 1,260 lots on a 12 × 12 grid of blocks. Where you build sets the toll. The toll is swapped to $BRICK and burned 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, which vary, 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.

Creator rewards: 80% to you

Every trade on a pump.fun coin pays a small fee, and part of it goes to the coin's creator. On the bonding curve that's 0.30% of every buy and sell. After graduation to PumpSwap it's 0.05% to 0.95% depending on market cap. Traders pay it as part of their trade.

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, not us. The coin's on-chain "creator" is the split itself, so rewards follow it automatically, before and after graduation.

Hourly payout rounds

Rewards collect in the coin's vault. Hourly payout rounds check vaults holding at least 0.01 SOL and eligible under pump.fun's distribution rules: 80% to the launcher and 20% to the city wallet, straight into the wallets. You don't have to claim anything. The city pays the network fee; payouts can be delayed if its gas wallet or RPC is unavailable. Recent payouts appear in the City pulse with their transactions.

Trade from any building

Click a building to open its card. Buy with SOL, or Sell 25%, 50%, 100% or any amount you hold. The card shows your balance and a quote from pump.fun before you approve. Buys push the building up; sells bring it down.

• Trades go through pump.fun's own programs: the bonding curve, or PumpSwap after graduation.
• The city adds no fee. pump.fun's normal trading fees apply.
• Your wallet signs; the city relays the transaction and resends it until it lands. You can always trade the same coin on pump.fun directly.

How buildings move

If the price feed drops, buildings freeze and the city says it's reconnecting. Missing data never shrinks a building.

Old Town

The north-east corner holds coins that were trading on pump.fun before the city existed, like Fartcoin, CATE, PARASITE and AIRPAD, so the city is alive from day one. They're guests: placed by the city, not for sale, no toll, and their fees stay exactly where they were. Being in Old Town doesn't mean a coin's team is involved with the city.

$BRICK

$BRICK is the city's coin, launched on pump.fun. Its building is the tower in the middle of the plaza, and it follows $BRICK's market cap on the same scale as everything else.

• Every new city launch burns $BRICK. Each available lot's toll buys $BRICK and burns it before coin creation. Old Town guests and coins placed before $BRICK went live paid no BRICK toll. Burns reduce $BRICK's supply for good; recent burns link their transactions in the City pulse.
• The HUD shows the total verified $BRICK toll burns and their quoted SOL value.

The dev wallet

$BRICK is launched from 6ddF5B57F2YdPtQg6TcgNCEiTM8tQWCAaVXdxXvkuyYf, which is also the city wallet that receives the 20% share. The dev holds for at least 72 hours after launch, then sells no more than 10% of the original dev buy per day, announced 24 hours ahead. Every move is visible on-chain.

Verify it yourself

Everything the city does happens on Solana, through pump.fun's programs. Check any building:

1. Copy the 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 city wallet at 20%, and is locked (admin revoked). If the city wallet itself launches, the two roles are the same address and the config lists it once at 100%. Payout transactions show the actual amounts.
3. Toll burns and payouts are linked from the City pulse with their transactions.

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

Risks, plainly

• Memecoins are extremely volatile. Most go to zero. Nothing here is financial advice.
• Trading can start immediately, including from bots. Trading activity and creator rewards are not guaranteed.
• Market caps are thin and easy to move. A tall building is not a safe coin.
• Locked means locked for us and for the launcher. pump.fun itself keeps admin powers over its own programs.
• Prices come from pump.fun trades and public data sources; they can lag or pause. Buildings freeze rather than guess.
• Being in Old Town doesn't mean a coin's team endorses the city.
