Every trade pays.
After graduation, it never stops.
A Kaching coin lives two lives: a fair bonding curve, then a real Uniswap market. Fees flow through both — in ETH — to the creator, holders, and the buyback flywheel. For the full feature tour, read the whitepaper.
One percent of every trade splits — forever — into the creator's cut, holder dividends and a $KACHING buyback, while the token side burns. $KACHING loops back as the flywheel.
The two lives of a coin
Fees exist in both phases, but they come from different places — the curve's trade fee before graduation, the Uniswap pool's swap fee after.
- 1
The bonding curve Live
Anyone launches a coin with a fixed 1,000,000,000 supply — no mint, no owner. 793.1M tokens sell on a virtual constant-product curve. Every buy and sell pays a fee, taken in ETH outside the reserves, so the curve's math stays exact — no honeypot, no hidden tax.

Graduation Live
Once the 793.1M sell out, the coin graduates automatically. The reserved tokens plus the raised ETH seed a real market, and the LP is burned and locked forever — nobody can pull the liquidity. The curve closes.

The Uniswap market Ships with mainnet
The graduated coin trades on canonical Uniswap. The locked liquidity earns a swap fee on every trade, forever — and Kaching routes that fee, in ETH, back to the creator, holders, and the flywheel.
Curve-phase fees
Only one curve fee is fixed — a 0.5% platform fee to $KACHING. Everything else is optional: you decide at launch whether your coin has a creator fee, a burn, holder dividends, or a buyback, and you set each rate yourself. Charge nothing beyond the 0.5%, or stack legs up to a 10% total — whatever you pick locks forever.
Your cut of every buy and sell.
Accrues ETH on the coin's own curve. Anyone can crank it to buy the coin off the curve and burn it — but the crank pays nothing, so most pots sit uncranked and end up as locked liquidity instead.
Streams ETH to holders — makes it a dividend coin. Anyone can flush the pot; nobody is paid to.
A price floor, not a buy: it never buys the coin back and has no crank at all. The ETH locks into the graduation liquidity, where nobody can withdraw it.
The 10% cap is absolute. The 0.5% platform fee plus whichever legs you turn on can never exceed 1000 bps, and every rate you pick is stamped into the coin at launch — changeable by no one, not you, not Kaching.
What the burn and buyback legs really do. Both accrue ETH in a pot on the coin's own curve — Kaching never holds it. The burn pot can be spent by anyone calling the permissionless crank, but the crank pays its caller nothing and no keeper runs it, so in practice pots are rarely cranked. The buyback pot has no crank at all: it never buys the coin back. Whatever is sitting in either pot at graduation is folded into the permanently locked liquidity instead — real, un-withdrawable ETH behind the coin, but not a buy and not a burn. And every one of these legs is a curve fee: after graduation they charge nothing at all.
Graduation — the numbers
Graduation isn't a vote or a threshold you set — it fires the moment the curve sells out. Because supply and the curve are fixed, it lands in the same place for every coin.
The graduation raise (~3.97 ETH) and opening cap (~19 ETH fully diluted) are the same for every launch — the ETH price × 19, whatever ETH is worth. Nothing here is set per-coin. At the fixed $3,200/ETH display rate this site uses for every dollar figure that is $60,800 — a display rate, not a live quote. Kaching has no price feed.
The perpetual engine Ships with mainnet
This is what makes graduation the beginning, not the end. Built this cycle; in external audit before it goes live with real funds.
The token half of every fee is burned to dead — permanent, automatic deflation.
Your cut of the ETH side of every swap — for as long as the coin trades.
Streams as ETH dividends to every holder, pro-rata (dividend coins).
Feeds the treasury, which buys back and burns $KACHING — the flywheel.
How long does it last?
Forever. The LP is locked permanently, so the 1% fee accrues for the life of the coin. No expiry, no unlock, no mcap trigger to switch it off.
Why Uniswap V3, not V4?
Canonical Uniswap V3, 1% fee tier — the real, verified deployment on Robinhood Chain. The fee sits in a locked, ownerless full-range position anyone can audit and crank, and the coin stays a plain ERC-20. V4's hooks would add a custom-code trust and audit surface for nothing we need here — so V3, deliberately.
Can the fee be redirected?
No. The split locks at graduation into an ownerless vault. Anyone can trigger a payout; nobody can change where it goes or pull the liquidity.
Model the perpetual fee
Illustrative · not a promise1% of every trade. The ETH side (from buys) is split; the token side (from sells) is burned. Assumes a 50/50 buy/sell mix — drag it. Real fees track real volume, which no one can promise.
What you can tune
Everything below is the creator's choice, set once at launch and then immutable. Skip it all and you get sensible defaults.
Curve fee mix
LiveSet the creator / burn / holders / buyback rates within the 10% cap. Locked forever at launch.
Dividend coin
LiveTurn on the holders fee to make it a dividend token — holders earn ETH, on the curve and (later) post-graduation.
Anti-snipe guards
LiveOptional per-wallet / per-block buy caps and an anti-bundle window for the opening blocks.
Custom post-grad split
MainnetChoose how the perpetual ETH fee divides — raise the $KACHING share, set the holders share. The 20% flywheel floor can't be lowered.
KOL cap-table
MainnetRoute a perpetual cut to collaborators — carved from your own slice, and each recipient must sign to consent.
Decaying creator curve
MainnetOptionally taper your creator share over time toward a floor; the freed share flows to holders or the flywheel.
What's live, and what's honest to say isn't
We won't tell you the perpetual engine is running when it isn't. Here's the true state.
- ✓The bonding curve, fixed supply, and all five curve-phase fees — creator, burn, holders, buyback, platform.
- ✓Automatic graduation into a real AMM at ~3.97 ETH, with the LP burned and liquidity locked.
- ✓The ETH holder-dividend and burn cranks during the curve phase — permissionless, and unpaid, so nobody runs them for you.
- ◷The perpetual Uniswap V3 fee engine — the 1% locked-LP split to creator / holders / $KACHING, forever.
- ◷Custom post-grad splits, consenting KOL cap-tables, and the decaying creator curve.
- ◷Gated on an external smart-contract audit and legal review. Built and internally reviewed — not deployed with real funds until those clear.
