Overview

SPOTTED is a launchpad for memecoins that buy real billboards. Every coin launches on Pons V2, on Robinhood Chain. Its creator fees don't go to a wallet: they go to the SPOTTED screen router, which spends them on digital out-of-home screens where the coin's poster plays.

The more a coin trades, the bigger its screens: a bus shelter in its home city first, then street billboards, then the giant screens of Shibuya or Piccadilly, and Times Square at the top. People who photograph those screens in the street get paid from the coin's spot pot.

Launching

A launch is one transaction through the SPOTTED screen router. It creates the coin and its bonding curve on Pons V2, makes the coin's own fee contract its creator fee recipient, and, if you want, makes your developer buy before anyone else can trade.

• Name, ticker, meme and description, plus optional links. The meme becomes the poster that plays on the screens.
• Creator tax, on top of the 1% Pons trade fee. It is fixed at launch and can never be raised. SPOTTED caps it at 5%.
• Home city: where the coin's first shelters are booked.

The launch pays the Pons launch fee (0.0005 ETH today, read from launchFee() when you launch) plus your developer buy, if any; whatever the curve can't fill comes back. For the first seconds after launch, Pons taxes buys at up to 99%, decaying to zero, so bots can't take the curve. Your developer buy is exempt. The launch carries the terms the page showed (Pons's fee and economics, SPOTTED's split): if they change while you sign, it fails rather than launch on other terms.

Trading

Until it graduates, a coin trades on its Pons V2 bonding curve: a constant-product curve with a virtual ETH reserve that sets the opening price. The more people buy, the higher the price goes; sells bring it down. Buys pay fees on the way in, sells on the way out, and every trade has a minimum-out for slippage.

When the curve has raised its graduation target (4.2 ETH for ETH-paired coins today, read from the launch config), it closes and the liquidity moves into a Uniswap V4 pool that is locked forever. Trades then go through the pool and the Pons meme hook, which charges the same trade fee and creator tax as the curve, so the fees keep flowing to the screens. The coin page trades it through Uniswap's Universal Router.

Fees

Every trade pays the Pons trade fee (1%). Pons keeps 30% of it; the rest of that fee and the whole creator tax are the coin's creator fees. For a SPOTTED coin they are credited in the Pons fee escrow to the coin's own fee contract, a small contract the router deploys for each coin, so every coin's money stays separate. Anyone can trigger a harvest: the router collects the fees and splits them the way it was set at launch:

Nobody can change a coin's split after launch, including SPOTTED. The coin's fee contract has no way to send its fees anywhere but the router.

Screens & the ladder

Every hour SPOTTED's booker takes each coin's screen fund to programmatic out-of-home exchanges and bids on the slots its level unlocks. The level depends on the creator fees the coin has earned since launch; with a 2% creator tax that is about $50K, $500K and $5M of trading:

Ad networks review every poster once before it airs. A refused poster doesn't play: the creator can submit a new one for review, and the fund waits in the meantime. Each screen that plays a poster sends back a proof-of-play log: where, when, for how long. Every booking is recorded on chain with its amount, and the hash of its proof-of-play report is attached once the slot has aired.

If SPOTTED ever stops booking a coin's screens, the money doesn't stay locked: after 90 days without a booking of that coin, its creator can take its screen fund and spot pot back.

Spot & earn

A fifth of every coin's creator fees fills its spot pot. When you see one of its screens, photograph it and submit the photo. It is checked against the proof-of-play logs: the right poster, on that screen, at that time and place. The first valid photo of a screen each hour is paid, in ETH: $20 on shelters and billboards, $35 on giant screens and $50 on Times Square, as long as the pot holds it. Each booking pays a few spots at most (six today), only for hours it was on air, claimed within two days.

Screenshots, edited photos and photos of photos are refused.

Contracts

Pons V2 on Robinhood Chain (chain ID 4663):

The SPOTTED screen router is written and tested against the live Pons V2 contracts, but not deployed on Robinhood Chain or audited yet. Until it is, the site runs as a demo, or live on a local copy of the chain with the real Pons V2 contracts (the network switch next to the wallet).

Risks

• Memecoins are extremely volatile. Most go to zero. Only use money you can lose.
• Screens depend on ad networks accepting the poster, and on the fund covering the slot (after graduation, pool fees reach it only when Pons's operator sweeps them). A coin can trade without being on air.
• Smart contracts can have bugs. Pons V2 contracts are Pons's; SPOTTED adds the router on top.
• Screens are bought off chain and spot photos are checked off chain: you trust SPOTTED to spend screen funds on screens and to pay honest spots. Every booking and payout is public on chain.
• The router's owner (a multisig) picks who books screens and checks spots, with 3 days' public notice (meanwhile any creator can take their coin's screen fund and spot pot back), and can pause them. It can't take a coin's funds or change its split.
• Pons's owner can redirect any coin's creator fees after a 3-day public notice. SPOTTED can't prevent it; the coin's page would show it.
• Nothing on this site is financial advice.
