The method
A quoin is the cornerstone that locks the wall. This yard applies the idea to liquidity: set the stone once, bond it, and let the chain do the holding.
One transaction, five moves
- 1. mint — the quarry, cut once. Never again.
- 2. split — the mason's course to the mason's wallet; the rest stays for the arch.
- 3. seat — the arch becomes one v4 position, opening at the fixed price in the code.
- 4. bond — the Banker wedges the arch into the Keystone. BONDED. Done means done.
- 5. groundwork — any ETH sent along buys through the fresh pool, paying the same lime.
The words on this yard
- Banker
- the launchpad contract — the mason's bench. `set` cuts a coin; `setHouse` cuts $QOIN, once, by the yard.
- Stone
- a coin. A plain, renounced ERC20 — nothing in it for a scanner to squint at.
- Mortar
- one shared Uniswap v4 hook every pool is laid in. It takes the lime and keeps the troughs.
- The arch
- the single LP position holding the pool's supply, seated from the opening price down.
- Keystone
- the position-NFT locker. The Banker wedges the arch in at set with BONDED — no strike call exists for it.
- Lime
- the swap fee, taken on each swap's ETH side and booked to the mason's trough. `slake()` draws it.
- The mason's course
- the share of supply that goes to the coin's creator at set.
- Groundwork
- ETH sent along with `set` — a dev-buy in the same transaction, same pool, same lime.
- Hod
- the router and quoter: buy, sell, quoteBuy, quoteSell.
- Lintel
- an ERC20 lock and linear vest, so a mason who wants their course provably locked can prove it.
Asked straight, answered straight
+Can the LP be pulled?
No. At set, the position NFT moves into the Keystone with a bond that has no unlock path. Not the mason, not the yard, not a new owner of anything can take it out. This is the pad's one idea.
+So a stone cannot rug at all?
At the LP, it cannot. The honest rest: the mason holds a course of supply and can sell it into the pool. Each stone's page shows the mason's live balance so you can see whether they have.
+Where does the lime go?
All of it to the mason's trough in the Mortar, in ETH, per swap. The yard takes no share of trades; its only income is a small flat fee on optional Keystone and Lintel use.
+What does a coin open at?
The same fixed market cap, every time. It is a constant in the code — no oracle, no signer, nothing to lean on. The exact figure is in the contract, where it belongs.
+Why 'bonded' and not 'burnt'?
Because burnt would be a lie. The NFT sits in the Keystone, not the dead address; some scanners will still show their burn badge red. The lock is real and the words stay exact.
