# gat0 — the black cat with a floor

*A sat0 successor for Robinhood Chain. One immutable contract. No owner, no dev, no off-switch. It
buys the cat and it can't be stopped.*

---

## 1. The one-paragraph version
gat0 is a token whose price sits on a curve backed by a real ETH **floor** that can only ever go
**up**. Every buy pays a small fee into a **pouch**; the pouch autonomously buys **CASHCAT** (the
chain's top memecoin) on Uniswap, and whenever that bet is in profit the gains are ratcheted into the
floor — so holders' redemption price keeps rising. The contract hits **nine "lives"** as it grows, and
at the last one it **retires its own tax to zero**. If nobody feeds it, **the cat starves** — the
pouch drains into the floor instead. It is a single contract with **no admin key**: nobody can pause,
upgrade, mint, or drain it. Ever.

## 2. How the curve + floor work
- **Price curve.** GAT0 is minted on an exponential bonding curve, `price = p0 · e^(k·supply)`. Early
  buyers pay less; each buy nudges the price up. Max supply is **9,000,000 GAT0**. The first 1% of
  supply costs about **1.09 ETH**; by the final life the price is ~**148×** the genesis price.
- **The floor.** Every net ETH you pay to mint goes into `curveReserve` — the **redemption floor**.
  You can **sell** your GAT0 back to the curve at any time and get ETH out of that reserve (on-chain,
  selling is the `burn` function: your tokens are destroyed and the vault pays you). Solvency is
  a hard rule of the contract: **the reserve always covers every holder's redemption**
  (`reserve ≥ R(supply)`) — it held across millions of simulated transactions and a full live
  dress-rehearsal before launch.
- **Ratchet up, never down.** `p0` (the floor parameter) only ever increases. Sell fees, hunt profits,
  donations, and "starve" drains all push it up. The floor is a one-way ratchet.

## 3. Tokenomics (fair launch, no premine)
| | |
|---|---|
| **Max supply** | 9,000,000 GAT0 |
| **Distribution** | 100% via the open bonding curve. **No premine, no team allocation** — the deployer mints on the same curve as everyone else, if at all. |
| **Mint fee (levy)** | **2.25%** to the pouch (the hunt fund); the other 97.75% goes straight into your floor. |
| **Launch ramp** | The levy starts at 9% and decays to 2.25% over the first 50 ETH of volume (anti-snipe). |
| **Anti-whale** | For the first 24h, no single buy can take more than 1% of supply. |
| **Sell fee** | **0.9%**, and it's **re-donated to the floor** — so even exits make the floor rise. |
| **Keeper bounty** | **0.3%** of each hunt action, paid to whoever calls it (see §6). |
| **Retirement** | At the 9th life the mint levy drops to **0% forever**. |

There is no emission, no inflation, no unlock schedule, no treasury. What you see is the whole design.

## 4. Nine lives
As cumulative buying grows past nine milestones (24 → 2,646 ETH of net mints), the cat gains a
**life**. Each life takes 9% of the pouch and **drips it into the floor over 9 hours** (lives are
spaced ≥24h apart, so the schedule can't be gamed). Lives are **one-way** — they never un-happen, even
if everyone sells out and the supply returns to zero. Hitting the **9th life triggers retirement**:
the mint tax turns off permanently, and gat0 coasts on its floor.

## 5. The hunt — gat0 buys CASHCAT
The pouch doesn't sit idle. It **hunts**:
- **Pounce** — buys CASHCAT with the pouch (bounded to a chunk size, only within a manipulation-
  resistant 4-hour TWAP price, so it never overpays).
- **Claw** — when the position is up ≥1.5×, it sells part and **ratchets the profit into the floor**.
- **Starve** — if an epoch (9 days) passes with little buying, the pouch **drains into the floor**
  instead. A neglected cat feeds the floor.
- **Deadprey** — if CASHCAT truly dies (price collapses to ≤30% of its peak for a sustained 4h, or the
  oracle goes dark for a week, or the position stays underwater for 60 days), the hunt **ends
  permanently**.
- **Scavenge** — after death, whatever CASHCAT is left is liquidated back to the floor.

Crucially, **the hunt can only ever risk the 2.25% pouch — never the floor.** Even if CASHCAT rugs to
zero, holders' redemption backing is untouched. The hunt is a *bonus bet on top of* a protected floor,
not a bet *with* it.

## 6. Ownerless by construction
gat0 has **no owner, no admin, no upgrade path, no pause, no selfdestruct, no delegatecall**. Every
parameter is frozen at deployment. The only things anyone can do are the public actions:
`mint`, `burn`, `donate` (anyone can pump the floor), and the permissionless hunt/maintenance calls
(`pounce / claw / deadprey / scavenge / starve / settleDrip / pokeOracle`), which pay a 0.3% bounty to
whoever runs them — so the machine keeps itself running without any privileged operator.

## 7. Why it works (the moat)
- **The floor only goes up.** Buys, sells, hunt profits, starves, and donations all ratchet it. There
  is no mechanism that lowers it. Downside is bounded by a rising floor; that's the whole appeal.
- **It backs the chain's runner.** gat0 systematically accumulates CASHCAT and turns wins into floor —
  aligning gat0 holders with the ecosystem's flagship memecoin, autonomously.
- **It ends its own tax.** Retirement is a built-in "the team can't rug the fees" guarantee, because
  there is no team and the fee turns itself off.
- **You cannot be rugged by a dev.** There is no dev with a lever. The contract is the whole thing.

## 8. Who wins, who loses — an honest model
We simulated **10,000 buyers** aping different amounts (many shrimp, a few whales) at random points
from genesis all the way to mint-out, on the exact production curve. No hype math — this is the shape
of the game:

**The road to mint-out**

| Milestone | What it takes | Price | Market cap |
|---|---|---|---|
| Life 9 — the tax retires | ~2,710 ETH of buys · **85% of supply minted** | 148× genesis | ~13,300 ETH |
| Mint-out (all 9,000,000) | ~6,480 ETH of buys | 359× genesis | ~37,900 ETH |

**At mint-out** — everyone still holding, bags valued at what selling would pay (after the 0.9% fee):

| Who | Outcome |
|---|---|
| The first buyer at genesis | **~310×** |
| A 59-ETH whale who aped mid-curve | ~6× |
| The median buyer | **~2×** |
| The very last buyer of the last push | **−0.9%** (just the sell fee) |

On the way **up**, nobody is ever down more than fees — the floor pays every exit at the current curve
price. The way **down** is a different story: read the next section. (Every floor ratchet — hunt wins,
exit fees, donations — shifts all of these numbers upward; we counted none of it here.)

## 9. Risks — real talk, read this twice
- **The floor protects the curve, not your entry price.** When people sell out, the price walks back
  *down* the curve. Your guaranteed exit is the sell **at the current curve price** — not at the price
  you paid.
- **You can absolutely get rekt.** There is **no guarantee you get out whole**. If you ape at the very
  top and everyone sells before you do, the math is brutal:

  | Supply that exits before you | Your bag |
  |---|---|
  | 5% | −26% |
  | 10% | −45% |
  | 25% | −77% |
  | 50% | **−95%** |

  Yes, **−95% or worse is possible**. The curve giveth on the way up and taketh on the way down — the
  only thing it *promises* is that selling always pays and the floor parameter never falls. Timing is
  on you. (The flip side: whoever buys low structurally can't be dumped below their entry — the genesis
  buyer's worst case, if literally everyone exits before them, is about −10%.)
- **CASHCAT is external and unverified.** Its behaviour (tax, liquidity) can change after launch. gat0
  treats it as hostile — the worst case is the *pouch* bleeding or some CASHCAT getting stranded,
  **never the floor**. A public monitor watches CASHCAT + pool health.
- **Immutable means immutable.** Nothing can be changed after launch — nobody can fix, pause, or
  rescue anything. That is the point.
- **Your exit is always the sell.** In every scenario, you can sell your GAT0 back and the reserve
  pays you the current curve price. It has no external dependency and cannot be blocked.
