1 Overview
Koi is a memecoin launchpad and trading platform on Sui. Anyone can launch a token for free, and every token starts the same way: the same fixed supply, the same locked mint, and the same open bonding curve. When a token proves demand, its liquidity moves to Cetus — Sui’s largest decentralised exchange — and the liquidity is burned forever. A single 1% fee on every trade is shared between the token’s creator, the referrer who brought the trader, and the platform.
2 Why Koi
Same rules for everyone. The creator buys on the same curve at the same price as anyone else. No presale, no allowlist, no insider allocation.
Rug-proof by design. Fixed supply, locked mint, burned liquidity and a fixed fee split are written into the contract itself.
A fair board. Trending is earned by real trading, never bought. Nothing on the board is promoted or paid for.
Built for speed. Sui settles a trade in under half a second, and Koi is built to keep up: one-tap trades with no wallet popups, several at once.
3 Launching a token
A launch is one transaction and costs only gas — a fraction of a cent. Pick a name, a ticker (up to 12 letters and digits, unique on Koi), an image, and optionally a description and links (X, Telegram, website).
Every token has exactly 1,000,000,000 supply. The mint is locked at launch, so no more can ever be created, and the token’s bonding curve opens for trading straight away.
The dev buy
A creator can add a first buy to the launch. It pays the same opening price as everyone else and is labelled on the token’s page, like every dev trade after it.
What the creator earns
55% of every trade fee on their token, forever — on the curve and after graduation alike, claimable at any time from the profile page.
4 The bonding curve
Until graduation, every token trades against its own bonding curve. There is no order book and nobody to wait for: you can always buy or sell instantly. Each buy pushes the price up along the curve, and each sell brings it back down.
5 Trading
Every trade — buy or sell, curve or pool — pays one 1% fee, in SUI. No deposit fees, no withdrawal fees, no listing fees, no subscriptions.
Slippage, handled for you
Every trade has a minimum you will accept. If the price moves past it, the trade simply does not happen — you are never filled at a bad price. By default Koi sets this automatically for each trade: tight on a small buy, wider on a big buy into a thin curve. Fixed settings (10/30/50% or your own) are one tap away, and the panel always shows your minimum before you trade.
Busy tokens
When a token is hot, Koi bids a little extra gas (still a fraction of a cent) so your trade gets in, and retries it for you if the network drops it. You do not have to do anything.
Tokens from other launchpads
Trenches and Trending also show tokens launched elsewhere — SuiPump today — and graduated tokens’ Cetus pools, each marked with where it trades. You buy and sell them from the same panel with the same one-tap buttons. Their own launchpad fee applies, and Koi adds a small routing fee of 1% in SUI.
Limit orders
Set a price and walk away. Your order and its funds sit on chain, not in your browser, so closing the tab or locking your phone changes nothing. When the price hits your trigger, the order fills and the tokens or SUI go straight to you. You can cancel any time for a full refund. An order still open when its token graduates is cancelled and refunded.
6 Graduation
When buys fill the curve (≈ 10,000 SUI), the token graduates. All the SUI raised and the reserved tokens move into a brand-new Cetus pool, and that liquidity is burned. Burned liquidity can never be pulled, by anyone: the pool’s depth is permanent.
After graduation, keep trading on Koi exactly as before — same panel, same fee, same one-tap buttons. The token also trades on Cetus and any Sui aggregator.
7 Fees & rewards
One fee: 1% of every trade, in SUI, on the curve and after graduation. The split is fixed in the contract:
Example: 1,000 SUI of volume on a token pays 10 SUI in fees — 5.5 SUI to its creator, 1.0 SUI to referrers and 3.5 SUI to the platform. Creators and referrers claim their share straight from the site.
Referrals
Share your referral link. When someone trades through it, they are linked to you on chain — and from then on, every trade that wallet makes pays you the referrer’s share automatically, on any token, forever. No payout run, no waiting: you are paid inside each trade.
8 The quick wallet
A wallet popup takes longer than Sui takes to settle a trade. The quick wallet removes the popup: a small trading wallet in your browser that signs instantly while 1-click is on. Deposit a trading balance from your main wallet, trade with zero popups, and withdraw everything back whenever you like.
Tap as fast as you want: rapid buys go out side by side instead of waiting in a queue. You can keep several pockets and trade from all of them at once.
Keep it safe
The quick wallet is a hot wallet. Its key is made in your browser or imported from your own wallet app, and it stays in that browser. Save a copy of a key Koi made for you — the wallet card can show and copy it — because clearing the site’s data removes it from the browser. Keep only a trading balance in it, never your savings.
9 How trending works
Trending ranks tokens by real activity over the chosen time window: volume (50%), number of trades (25%) and unique wallets (25%), with price movement and a short boost for brand-new launches. Unique wallets matter most: thirty real buyers beat one wallet trading with itself. Nothing on the board is promoted or paid for.
10 Trade smart
Memecoins are high-risk and can go to zero. Burned liquidity stops a rug pull, but it cannot make people want a token. Keep your quick wallet to a trading balance, and trade only what you can afford to lose.
11 FAQ
Is there a Koi platform token?
No, and none is planned or presold. Anyone claiming to sell you a Koi token is running a scam.
How is the fee split?
Every trade pays 1%, split 55/10/35 between the creator, the referrer and the platform.
Why did my trade fail?
Almost always slippage: the price moved past your minimum before the trade landed, so it did not fill at a worse price than you accepted. Nothing is lost but a tiny bit of gas. Try again, or raise the slippage a little on a very busy token.
What happens to my quick wallet if I clear my browser?
The key is removed from that browser. A key you imported is still in the wallet app it came from; a key Koi made for you is wherever you saved it. Import it again and everything in the wallet is yours again.
How do referrals work?
The first time a wallet trades through your link, it is linked to you for good. You earn the referrer’s share of every trade that wallet makes, on any token, paid inside each trade.
Which wallets are supported?
Every Sui wallet — Slush, Suiet, Ethos, Martian, OKX, Backpack, Nightly and more — is detected automatically.
