It takes π of every trade — half to whoever holds, half to buying its own supply back and burning it.
Scattered floor space, paid in tokenized Nvidia.
Who held how much is worked out by the launchpad, not by this site and not by a contract of ours. Pons snapshots balances at moments nobody can choose and publishes each round on chain as a Merkle root that anyone can check. There is nothing to register and nothing to poke. Because a balance is only ever read at a moment the claimant did not pick, a borrowed balance is worth nothing. What you are trusting is the launchpad's snapshot service — the same thing every launch on it trusts.
One of twelve, and the billboard on it.
A trader pays 4.14%. Up to one point of that is the launchpad's; today it keeps 0.30 and passes 0.70 on. The rest — π, or a little more — arrives as tokenized Nvidia, because that is what LDC is paired against. Half of it reaches holders. Half buys LDC off the market and burns it, so the supply actually falls. π in, and half of it never comes back.
Every action destroys tokens, half of every trade's creator fee buys tokens and destroys them, and nothing ever mints. Supply can only fall. What that means for the price of a token is not something this page will tell you.
You are sorted into a hall by your address. You do not pick — burning to move is the only way to choose. Whoever holds the largest burn weight runs it, and that weight halves every seven days, continuously. There are no monthly rounds to wait for: a burn from four weeks ago counts for a sixteenth of one made today. Sell out completely and the seat passes on the next block, whatever you burned.
Every hall has one billboard and one seat. Both are priced the same way, and both prices fall on their own.
A board. Empty, it costs 10,000 LDC to paint. Taken, it costs more than the standing of whoever painted it last — and standing halves every seven days. Paint it with 50,000 today and it takes 50,001 to paint over you today, 25,001 next week, 12,501 the week after, and 10,000 once it has fallen that far. Repainting your own board never costs more than 10,000; you do not have to beat yourself.
A seat. The seat belongs to whoever has the most standing in the
hall. Standing is everything you have burned into that hall, halving every
seven days. To take a seat you burn more than the operator's standing is
today. They are paid 30% of your burn on the way out; the rest is
destroyed. If your burn falls short, nothing happens and nothing is taken
from you — the site sends take(), which refuses a losing
challenge outright.
Holding the seat needs two things, not one. Your standing has to lead, and you have to still hold LDC — any amount at all. The second one catches people, because it has nothing to do with the building: sell your position to zero and the hall reads vacant on the very next block. Nobody has to out-burn you. While your balance is zero, burns into that hall pay you nothing — the 30% that would have been yours is destroyed along with the rest, and anyone can take the hall at the ten thousand minimum without paying you a thing.
What you keep is the standing itself. It is not
erased and it goes on decaying at the same rate as everyone else's, so holding
again — one wei is enough — switches it back on, and
unseat(hall, you) takes the hall back from whoever moved in, for
gas, if your standing still beats theirs. Which is also the warning for the
other side of that trade: a hall that reads open because its operator sold out
is not cheap. Price it against their standing, not against the minimum.
Why they are one number. A paint and a seat challenge both add to the same standing figure, per address, per hall. Paint big enough and you have taken the seat as well. The reverse is not true: taking the seat does not repaint the board. The seat is the cheaper way to hold a hall; the board is the louder way.
Why anyone pays more than the minimum. Price buys time. 200,000 of standing is still 12,500 after four weeks and does not fall to 10,000 until day 31, so nobody can touch you for a month; a seat taken at 10,000 can be taken by anyone tomorrow. And the operator is paid: 30% of every burn into the hall — every paint, every move in, every challenge that lands — goes to whoever holds the seat. A hall that is being painted is a hall whose operator is being paid.
One thing to know before you read "vacant". An operator who sells
to zero forfeits the seat, but their standing stays on the books, and a
single token back in their wallet revives it. So "vacant" here means
10,000 takes it, unless they come back first. A short challenge
against a revived operator would still cost nothing — that is what
take() is for.
| day 0 | you paint hall D for 50,000. to paint over you: 50,001. the operator was paid 15,000; 35,000 is gone. |
| day 7 | 25,001 paints over you. nobody has; it keeps falling. |
| day 9 | somebody paints for 30,000. the board is theirs; to retake it today: 30,001. |
| day 21 | their 30,000 has fallen below the floor. 10,000 paints over them. |
| Pull the liquidity | impossible — no such function exists |
| Mint more | impossible — fixed at 1,000,000,000 |
| Pause or freeze you | not us. LDC is a plain token nobody can pause; NVDA is a Robinhood Chain Stock Token with a blocklist and a pause, so a frozen wallet cannot be paid |
| Take your floor | no contract here can move your tokens; the token itself is Pons’s, and the docs above say what they can and cannot do |
| Team allocation | none — no presale, no allowlist |
| Change where the fee goes | possible for Pons, not for us. the launchpad’s owner can re-route any launch’s creator fees with a 3-day timelock; we cannot, and the keeper watches that seat |
| Stop the holders’ half | possible for Pons, not for us. rounds are published and paid by the launchpad’s distributor; if it stopped, that half would wait in the forwarder and the burn half would carry on |
| Check all of it yourself | yes — below, and every number with its tx hashes at /proof/. the token, engine, crank and building have verified source on the explorer; the holder distributor is the launchpad’s proxy, verified shell, unverified implementation; the burner and the forwarder are not verified yet, and their on-chain code matches the repo’s build byte-for-byte |
These are the only addresses. Anything else calling itself $LDC is fake.
| π collected and split | live — the engine is the creator-fee recipient; anyone pushes it through the crank |
| Half buys LDC and burns it | live — 0.5 NVDA per burn, one a minute, supply falls on chain |
| Half paid to holders in NVDA | live — rounds published and paid by the launchpad, straight to wallets |
| Burn to put an image on a billboard | live — halls H and K were painted on launch night |
| Burn to claim a name | live |
| Operator seats, standings, relocation | live |
| Receipts minted by a burn | live — plates draw the billboard image only while its on-chain hash still matches the one stamped at the burn |
| Keeper that presses the crank and the burner | not yet — until it runs, fees move when someone presses the buttons on the site |
| Independent audit | none. an adversarial review of the live contracts is being run and will be published here |
Honest limits: the building keeps the last 64 lines of the record and the last 128 ledger entries readable on chain; older ones survive only in the event log, which this chain’s public nodes prune. The burn is permanent; the display is a window. A name is held per exact label: every label you ever claimed stays yours until someone burns more for it, and losing any of them clears the name you show. Look-alike labels are separate labels.
rounds, whales, claim buttons, keys, plates, seats, buttons: plain answers, with the addresses to check them.
