OPEN SOURCE · A DEPLOYER WITH NO TOKEN OF ITS OWN

Every launchpad has a house token.
Sling has a flywheel.

The house token is the catch: the seat a launchpad keeps at its own table, the exit wearing a logo. Sling keeps nothing of the kind. The contracts are open source and frozen at birth, the liquidity can never leave, and the machine works only for the token and whoever launched it, taking its 10% in the open. Nothing of ours to dump, nothing to pull, nothing to trust. Read the code instead.

The house keeps 10%.
The other 90% never leaves the table.

00 · THE CONFLICT — WHY SLING EXISTS

A launchpad that holds its own token runs two businesses: the tokens it launches, and the token it keeps. Fees orbit the second one. Attention orbits the second one. Eventually, the exit runs through the second one.

Sling runs one business, and the margin is printed on the receipt: 10%, in the open. We deleted the second business before it could exist. There is no $SLING — not "later", not "for the community", not ever promised. The launches are the product. The loop is the point.

01 · THE LOOP — WHAT A FEE DOES HERE

90% of every fee goes back to where it came from.

Two shares leave the track — the creator's and ours. The 40% stays on it: collected permissionlessly, swapped into the token through its own pool, and parked at 0xdEaD, out of circulation forever. Every turn of the wheel is a buy the market didn't have to make.

TRADE any wallet, the pool, nothing in between 1% POOL FEE THE SPLIT 40% BUY-AND-BURN swapped into the token, parked at 0xdEaD SUPPLY OUT, FOREVER 50% THE CREATOR 10% THE HOUSE
01TRADE — any wallet, the pool, nothing in between
021% POOL FEE — every swap, every time
03THE SPLIT — 50% to the creator, 10% to the house: those two leave the track
0440% BUY-AND-BURN — swapped into the token, parked at 0xdEaD
05BACK TO 01 — supply out of circulation, wheel intact
50% THE CREATOR Claimable anytime, in both currencies. Pull-pattern — the money waits for the creator, never the reverse.
40% THE TOKEN Automatic buy-and-burn to 0xdEaD. No other launchpad on this chain returns a wei to the tokens themselves.
10% THE HOUSE Ours, in the open. That is the entire business model, visible on-chain.

Burn boost — the creator's one knob: at creation, a creator may move up to 50 points of their own 50% into the burn, permanently. A token can launch anywhere from BURN 40% to BURN 90%, and the number is printed on its card forever. It comes out of the creator's own share — the 40% burn floor and the 10% never move.

02 · THE RUG-PROOF RECEIPT

Every claim maps to something you can read on-chain.

Trust nothing. Check everything. Each line ships with a proof link the day contracts hit mainnet.

R-01Liquidity can never leave.100% of supply sits in a Uniswap V3 position owned by SlingLocker — a contract with no function to withdraw or decrease it.
R-02Supply is fixed. 1,000,000,000, once.No mint, no owner, no pause, no blacklist, no upgrade hook. The ERC-20 is frozen at birth; burned tokens sit at 0xdEaD, out of circulation forever.
R-03The split is 50/40/10, forever.Constants, not settings. There is no function that changes them and no one with the keys to try.
R-04Burns only ever reach 0xdEaD.The recycle path is the system's only swap and its output address is hardcoded to the dead address. Watch the balance grow on any explorer.
R-05No wallet holds more than 2% before graduation.Enforced by the token itself until the pool crosses 20 ETH FDV, then off permanently. Snipers fight the contract, not our goodwill.
R-06This website is expendable.Frontend is open-source with an IPFS mirror; trading lives on Uniswap and keeps working if every Sling server dies. We learned from watching the incumbent go dark for two days.

03 · THE FIELD

Everyone else kept a token they can dump.

LAUNCHPADFEE SPLITHOUSE TOKEN
LaunchHood50 creator / 50 houseyes
Robin50 creator / 50 houseyes
Hood Launcher80 creator / 20 houseyes
SLING50 creator / 40 token burn / 10 housenone

Nobody else returns a wei to the tokens themselves — and every one of them holds a platform token whose exit dilutes its own users. Sling's 40% goes into the only asset that matters here: the one being traded. Absence of a house token isn't a missing feature. It's the feature.

04 · THE LOOP, IN PUBLIC

Facts that post themselves are the only ad we run.

Creators claim in public. Burns and graduations post themselves, with proof links. Keepers get paid to keep the wheel turning. Artifacts below come from the growth-kit demo — simulated data, real code.

KEEPERSA PAID, PERMISSIONLESS JOB

Anyone who calls recycle() earns 1% of the WETH burned, same transaction, no registration. Run it from a Telegram bot, a cron job, a Raspberry Pi. The flywheel pays its own operators — that is what "doesn't need us" means.

05 · SIXTY SECONDS

Create. Trade. Collect. Nothing in between.

01 · CREATE

One transaction, gas only

Name, ticker, image. Optional dev-buy and burn boost. The pool exists and prices before the block is old.

02 · TRADE

Uniswap V3 from block one

No bonding curve, no graduation cliff, no migration event. Your wallet, the pool, nothing of ours in the middle.

03 · COLLECT

Fees split themselves

The creator claims their 50% anytime, in both currencies. The 40% burn runs permissionlessly — keepers race to trigger it because it pays them.

06 · MANIFESTO

Sling is a deployer. No roadmap. No Discord. No promises. No admin keys. No house token. The contracts are immutable. The liquidity is locked forever. 50% of every fee is the creator's; 40% burns the token itself, automatically; 10% is the house's, and the house says so out loud.

We built the loop instead of a token because a loop can't be dumped, paused, seized, or talked into a bad decision. Don't trust us today — read the constants in a year. They will say the same thing. We may disappear tomorrow. The protocol won't.
