<p><b>Fixed limit</b> — a price you name. It rests until someone fills it or you cancel.</p>
<p><b>Dutch decay</b> — starts above your floor and falls to it over a window you choose. It has two clocks: the decay, then how long it rests at the floor before the escrow returns to you. Set that to <em>Forever</em> and it waits until you cancel.</p>
<p><b>Climbing bid</b> — the mirror: a bid that rises toward a ceiling you name.</p>
<p>Orders are escrowed on chain when placed, so a fill cannot fail for want of funds, and cancelling returns the escrow. Boards are denominated in WETH — an order asking for ETH is asking for WETH, and pays out as such.</p>
<p>The <b>book</b> under the form is live and takeable. Yours sit at the top; everyone else’s come cheapest first for the pair above, each row carrying its own unit price. <b>Fill</b> takes a single order, in part where it allows it. That same book is priced into every Swap quote — a swap that beats the pools on resting orders says <em>Orderbook</em> beside the rate, with the share it took.</p></details>

<p>Precision pools are <b>bands</b>, not endless curves. A position earns fees only while the price is inside its band, and holds one asset or the other at the edges. A wider band is safer and earns less; a narrow one is the opposite.</p>
<p>The bar on each row shows where the price sits in that band. <em>Out of range</em> means it is earning nothing right now.</p></details>

<p>One transaction, and no ether needed aside from gas. A fixed supply is minted, your allocation is paid to you immediately, and <b>everything else is seeded into a fresh ETH pool</b> — one-sided, so the pool opens holding only your token.</p>
<p><b>Starting market cap</b> is the pool's virtual ether reserve. It sets the opening price and how hard that price is to move, which are the same dial: roughly that much buying moves the market halfway. Small numbers mean the first buyer takes a large share of the supply, which is why the form says what one ether would buy.</p>
<p><b>Creator keeps</b> is a share of the token SUPPLY, minted straight to you when the coin launches — tokens, not ether, and not a fee on trading. Keep 10% of a billion and 100,000,000 land in your wallet at once, unlocked, with nothing vesting.</p>
<p>Whatever you keep does not go into the pool, and selling it later pulls ether back out of that pool — so a modest-looking percentage can be a claim on most of what early buyers put in. Anyone deciding whether to buy your coin can work that out too.</p>
<p>A <b>logo</b> is stored as contract code on Ethereum — no IPFS, no pinning service, nothing to go dark. Upload anything; the page compresses it and shows the size before you sign. You can replace it later.</p></details>
<details><summary>Launching a cause <em><svg width="12" height="12" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" aria-hidden="true"><circle cx="12" cy="12" r="9"/><circle cx="12" cy="12" r="3.5"/></svg></em></summary>
<p>The other half of the launcher, and a different thing entirely: no pool, no market, no trading. Ten million units are offered at a fixed price in ether — your <b>goal</b> divided by ten million — and what backers pay accumulates in a treasury that belongs to the cause, not to you.</p>
<p>Two clocks, and they are deliberately different lengths. <b>Runs for</b> is how long backing stays open. <b>Released over</b> sets a fixed <b>rate</b>, not a fixed fraction: the tap pays out your <em>goal</em> divided by that window, every second, whatever was actually raised. Ten ether released over a year is under three hundredths of an ether a day.</p>
<p><b>So a cause that raises less than its goal empties faster than the window suggests.</b> Raise a tenth of the goal and the treasury is drained in a tenth of the time — a tenth of a year, not a year. Since what has not been released is exactly what a backer can still burn back for, an under-subscribed cause can leave its backers with nothing well before the release window is over. Set the window long enough that a partial raise still leaves something behind, and read the daily figure below as the speed at full funding.</p>
<p>The release clock starts the moment you launch and runs whether or not anyone has backed you yet, which is why it wants to be much longer than the raise. Release over the same thirty days you raise for and the whole treasury is yours the day backing closes — and somebody who backed you on the last day gets nothing back, because there is nothing left unreleased.</p>
<p>That is what makes the token worth something on its own: <b>whatever has not been released yet can be burned back for</b>. A backer who changes their mind, or who watches a cause go quiet, redeems their share of the untouched treasury and takes their ether home. Nobody has to agree and nothing has to be voted on.</p>
<p><b>The creator can close that exit, but not quietly and not quickly.</b> Burning calls <code>ragequit</code>, which the DAO can disable — and since the creator holds the only share, they alone can propose it and carry the vote. What they cannot do is act on it at once: the change has to go through the DAO, which queues it on chain and then waits out a <b>three-day timelock</b> before it can be executed. That queue is public from the moment it is entered, and burning back stays open the whole time. So the protection is not that nobody can take the exit away; it is that taking it away is visible, and slower than leaving.</p>
<p>Backers hold <b>loot</b>, which carries that claim and no vote. You keep a single share and the vote that comes with it, and you buy that share at the same price everyone else pays — so your claim on the treasury is the same shape as theirs.</p>
<p>Paste a cause’s token into the swap and the page prices the burn for you, against the treasury rather than against a market. It is the only price such a token has, and it is the honest one.</p></details>
<details><summary>Fees</summary>
<p>A launched market charges <b>1%</b> per swap. Half of that stays in the pool as reserves, which raises the floor for every holder. The other half is collectable, and splits <b>80% creator, 10% protocol, 10% tithe</b>.</p>
<p>The <b>tithe</b> is burned to Ethereum itself. The ether goes to the BETH burner, which destroys it and mints a BETH receipt recording that it happened. Nobody can spend it and it cannot be redeemed — the ether no longer exists. What it buys is a smaller ether supply, which accrues to everyone holding ether rather than to us.</p>
<p>The token side of collected fees is burned outright too — a launched coin's supply only ever falls.</p></details>
<details><summary>What this page is</summary>
<p>There is no server. This page is served from a contract, executes only its own bytes, and needs nothing but an Ethereum node to quote and swap. Those bytes cannot be changed by anyone, us included — a new version is a new address, not an edit. The token list is a contract too, artwork included; so are the node list, the solver roster, and the adapter an outside route settles through. It talks to your wallet, to Ethereum, and — when you ask for a quote — to the aggregators listed under Swapping. Which ones those are is itself recorded on chain and curated there, not decided by this page or by whoever answers a request; any of them can be switched off in a single transaction. They are asked for a price on a pair and a size, and <b>they are not told who is asking</b>: the address they are given is the shared adapter, the same one in every other person’s request. They never see a key, and they cannot move anything, because what they return is bounded on chain before it settles. Pin <b>On-chain</b> in the venue list to skip them entirely. WalletConnect is the other outside party: reaching your phone needs its relay. Reads go through a public node you can point anywhere you like.</p>
<p>Your keys never leave your wallet. Nothing here custodies your funds; every trade settles from your address to a contract you can read.</p>
<p>The token list is <b>zList</b>, ranked on chain by conviction staking. Anything not on it can still be traded by pasting its address.</p></details>

<details><summary>Swapping</summary>
<p>Every quote is compared across Uniswap v2, v3 and v4, Curve, Sushi, zAMM, Lido, our own Precision pools and the on-chain orderbook, and the best one wins. One route, one signature.</p>
<p>A handful of outside aggregators are asked too — 0x, 1inch, ParaSwap, KyberSwap, Enso, Bebop, OKX. They are compared on what they can be <b>held to</b>, not on what they advertise: a quote less its slippage, against the same number for the chain. One only wins if it beats the chain by a margin wide enough to cover the extra gas, and if none of them answer, nothing changes. Tap the <b>▾</b> beside the rate to see every venue that replied and what each was worth.</p>
<p>An outside route is executed through a small adapter that <b>measures what actually arrives</b> and reverts if it is less than your minimum. The adapter is named in this page's own bytes, so a bad answer from a node cannot swap it for another one.</p>
<p><b>Slippage</b> is the worst price you will accept — move past it and the trade reverts rather than filling badly. <b>Price impact</b> is how far your own size moves the price; the page warns as it grows and will not let a very bad one through quietly.</p>
<p>ETH and WETH are interchangeable here. The page wraps or unwraps whichever way the pool needs, inside the same transaction.</p></details>

<p>A plain transfer, or a <b>SLOW</b> one: time-locked, and reversible by you at any point until it matures. Useful for large amounts and for addresses you have not paid before.</p>
<p>A locked transfer does not deliver itself — someone must send the claim once it matures. Tick <b>auto-claim</b> and the page posts a small tip so a keeper does that for the recipient. The tip is refundable: reverse the trans

is minted, your allocation is paid to you immediately, and <b>everything else is seeded into a fresh ETH pool</b> — one-sided, so the pool opens holding only your token.</p>
<p><b>Starting market cap</b> is the pool's virtual ether reserve. It sets the opening price and how hard that price is to move, which are the same dial: roughly that much buying moves the market halfway. Small numbers mean the first buyer takes a large share of the supply, which is why the form says what one ether would buy.</p>
<p><b>Creator keeps</b> is a share of the token SUPPLY, minted straight to you when the coin launches — tokens, not ether, and not a fee on trading. Keep 10% of a billion and 100,000,000 land in your wallet at once, unlocked, with nothing vesting.</p>
<p>Whatever you keep does not go into the pool, and selling it later pulls ether back out of that pool — so a modest-looking percentage can be a claim on most of what early buyers put in. Anyone deciding whether to buy your coin can work that out too.</p>
<p>A <b>logo</b> is stored as contract code on Ethereum — no IPFS, no pinning service, nothing to go dark. Upload anything; the page compresses it and shows the size before you sign. You can replace it later.</p></details>
<details><summary>Launching a cause <em><svg width="12" height="12" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" aria-hidden="true"><circle cx="12" cy="12" r="9"/><circle cx="12" cy="12" r="3.5"/></svg></em></summary>
<p>The other half of the launcher, and a different thing entirely: no pool, no market, no trading. Ten million units are offered at a fixed price in ether — your <b>goal</b> divided by ten million — and what backers pay accumulates in a treasury that belongs to the cause, not to you.</p>
<p>Two clocks, and they are deliberately different lengths. <b>Runs for</b> is how long backing stays open. <b>Released over</b> sets a fixed <b>rate</b>, not a fixed fraction: the tap pays out your <em>goal</em> divided by that window, every second, whatever was actually raised. Ten ether released over a year is under three hundredths of an ether a day.</p>
<p><b>So a cause that raises less than its goal empties faster than the window suggests.</b> Raise a tenth of the goal and the treasury is drained in a tenth of the time — a tenth of a year, not a year. Since what has not been released is exactly what a backer can still burn back for, an under-subscribed cause can leave its backers with nothing well before the release window is over. Set the window long enough that a partial raise still leaves something behind, and read the daily figure below as the speed at full funding.</p>
<p>The release clock starts the moment you launch and runs whether or not anyone has backed you yet, which is why it wants to be much longer than the raise. Release over the same thirty days you raise for and the whole treasury is yours the day backing closes — and somebody who backed you on the last day gets nothing back, because there is nothing left unreleased.</p>
<p>That is what makes the token worth something on its own: <b>whatever has not been released yet can be burned back for</b>. A backer who changes their mind, or who watches a cause go quiet, redeems their share of the untouched treasury and takes their ether home. Nobody has to agree and nothing has to be voted on.</p>
<p><b>The creator can close that exit, but not quietly and not quickly.</b> Burning calls <code>ragequit</code>, which the DAO can disable — and since the creator holds the only share, they alone can propose it and carry the vote. What they cannot do is act on it at once: the change has to go through the DAO, which queues it on chain and then waits out a <b>three-day timelock</b> before it can be executed. That queue is public from the moment it is entered, and burning back stays open the whole time. So the protection is not that nobody can take the exit away; it is that taking it away is visible, and slower than leaving.</p>
<p>Backers hold <b>loot</b>, which carries that claim and no vote. You keep a single share and the vote that comes with it, and you buy that share at the same price everyone else pays — so your claim on the treasury is the same shape as theirs.</p>
<p>Paste a cause’s token into the swap and the page prices the burn for you, against the treasury rather than against a market. It is the only price such a token has, and it is the honest one.</p></details>
<details><summary>Fees</summary>
<p>A launched market charges <b>1%</b> per swap. Half of that stays in the pool as reserves, which raises the floor for every holder. The other half is collectable, and splits <b>80% creator, 10% protocol, 10% tithe</b>.</p>
<p>The <b>tithe</b> is burned to Ethereum itself. The ether goes to the BETH burner, which destroys it and mints a BETH receipt recording that it happened. Nobody can spend it and it cannot be redeemed — the ether no longer exists. What it buys is a smaller ether supply, which accrues to everyone holding ether rather than to us.</p>
<p>The token side of collected fees is burned outright too — a launched coin's supply only ever falls.</p></details>
<details><summary>What this page is</summary>
<p>There is no server. This page is served from a contract, executes only its own bytes, and needs nothing but an Ethereum node to quote and swap. Those bytes cannot be changed by anyone, us included — a new version is a new address, not an edit. The token list is a contract too, artwork included; so are the node list, the solver roster, and the adapter an outside route settles through. It talks to your wallet, to Ethereum, and — when you ask for a quote — to the aggregators listed under Swapping. Which ones those are is itself recorded on chain and curated there, not decided by this page or by whoever answers a request; any of them can be switched off in a single transaction. They are asked for a price on a pair and a size, and <b>they are not told who is asking</b>: the address they are given is the shared adapter, the same one in every other person’s request. They never see a key, and they cannot move anything, because what they return is bounded on chain before it settles. Pin <b>On-chain</b> in the venue list to skip them entirely. WalletConnect is the other outside party: reaching your phone needs its relay. Reads go through a public node you can point anywhere you like.</p>
<p>Your keys never leave your wallet. Nothing here custodies your funds; every trade settles from your address to a contract you can read.</p>
<p>The token list is <b>zList</b>, ranked on chain by conviction staking. Anything not on it can still be traded by pasting its address.</p></details>

<details><summary>Swapping</summary>
<p>Every quote is compared across Uniswap v2, v3 and v4, Curve, Sushi, zAMM, Lido, our own Precision pools and the on-chain orderbook, and the best one wins. One route, one signature.</p>
<p>A handful of outside aggregators are asked too — 0x, 1inch, ParaSwap, KyberSwap, Enso, Bebop, OKX. They are compared on what they can be <b>held to</b>, not on what they advertise: a quote less its slippage, against the same number for the chain. One only wins if it beats the chain by a margin wide enough to cover the extra gas, and if none of them answer, nothing changes. Tap the <b>▾</b> beside the rate to see every venue that replied and what each was worth.</p>
<p>An outside route is executed through a small adapter that <b>measures what actually arrives</b> and reverts if it is less than your minimum. The adapter is named in this page's own bytes, so a bad answer from a node cannot swap it for another one.</p>
<p><b>Slippage</b> is the worst price you will accept — move past it and the trade reverts rather than filling badly. <b>Price impact</b> is how far your own size moves the price; the page warns as it grows and will not let a very bad one through quietly.</p>
<p>ETH and WETH are interchangeable here. The page wraps or unwraps whichever way the pool needs, inside the same transaction.</p></details>
<details><summary>Sending</summary>
<p>A plain transfer, or a <b>SLOW</b> one: time-locked, and reversible by you at any point until it matures. Useful for large amounts and for addresses you have not paid before.</p>
<p>A locked transfer does not deliver itself — someone must send the claim once it matures. Tick <b>auto-claim</b> and the page posts a small tip so a keeper does that for the recipient. The tip is refundable: reverse the transfer and it comes back.</p></details>
<details><summary>Orders</summary>
<p><b>Fixed limit</b> — a price you name. It rests until someone fills it or you cancel.</p>
<p><b>Dutch decay</b> — starts above your floor and falls to it over a window you choose. It has two clocks: the decay, then how long it rests at the floor before the escrow returns to you. Set that to <em>Forever</em> and it waits until you cancel.</p>
<p><b>Climbing bid</b> — the mirror: a bid that rises toward a ceiling you name.</p>
<p>Orders are escrowed on chain when placed, so a fill cannot fail for want of funds, and cancelling returns the escrow. Boards are denominated in WETH — an order asking for ETH is asking for WETH, and pays out as such.</p>
<p>The <b>book</b> under the form is live and takeable. Yours sit at the top; everyone else’s come cheapest first for the pair above, each row carrying its own unit price. <b>Fill</b> takes a single order, in part where it allows it. That same book is priced into every Swap quote — a swap that beats the pools on resting orders says <em>Orderbook</em> beside the rate, with the share it took.</p></details>
<details><summary>Liquidity <em><svg width="12" height="12" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" aria-hidden="true"><path d="M12 3.2c3.6 4 6 7.2 6 10.1a6 6 0 0 1-12 0c0-2.9 2.4-6.1 6-10.1z"/></svg></em></summary>
<p>Precision pools are <b>bands</b>, not endless curves. A position earns fees only while the price is inside its band, and holds one asset or the other at the edges. A wider band is safer and earns less; a narrow one is the opposite.</p>
<p>The bar on each row shows where the price sits in that band. <em>Out of range</em> means it is earning nothing right now.</p></details>
