How Fizz works
New to token launches? Start here.
Which chain does my token live on?
Fizz runs on several chains, and a launch happens on one of them: you pick it when you create the token, and that is where the coin lives, trades and stays. Which chains are open is shown in the app itself: the picker on the create page lists the ones you can launch on, and a token's own page tells you whether trading is open where it lives. Not all of it is a rehearsal: a launch is already live on a main network, where the money is real.
Some of the chains in that list are test networks. They exist so the contracts can be exercised with nothing at stake, and a coin launched or bought on one is worth nothing and always will be. The chain control marks them, and changes colour while you are on one. Nothing there costs real money, and nothing there can earn any.
What do I pay with?
Two coins matter on any chain: the one that pays gas, and the one you buy tokens with. On some chains both are a dollar unit, which is what makes costs there predictable and leaves no volatile gas token to think about. On others gas is paid in the chain's own coin while buying happens in a dollar unit beside it. The app names both for the chain you are connected to, so it is never a guess. Amounts across the site are shown in USD because that is easier to read.
How to buy a token
- Connect a wallet and add the chain you want to launch or buy on.
- Fund it with the coins that chain uses. The app names them.
- Pick a token from the Feed.
- Enter an amount, review the quote (and slippage), and hit Buy.
- Confirm in your wallet. You receive the tokens instantly.
Selling works the same way, in reverse.
How a launch works
The whole supply goes straight into a Uniswap pool the moment the token is created, spread across a series of price bands. Buying walks the price up through them; the money paid stays in the pool as real liquidity, which is what anyone selling trades against. There is no presale and no phase to wait through. The token is on a public exchange from its first block, so any wallet, router or aggregator can reach it.
The liquidity is locked forever. It sits in a position nobody can withdraw from, not the creator and not us, because no function exists that removes it.
The cheapest band is deliberately the smallest, so buying it out immediately pushes the price into the next band up. Each token's page states the exact promise, for example “at most 5% of the supply was available under 2x the starting price”. It is not a cap on holdings. Someone with enough money can still end up with a large share; they just pay the market price for everything past that first slice. A funded bot spread across many wallets still gets a good entry, and no launch on a public exchange prevents that.
Fees
- Launch: a small fixed fee to create a token. The create page shows the exact amount, in the coin that chain charges it in.
- Trading: the pool takes a flat 1%, the same on buying and on selling. That one is the exchange's own fee, not ours, and no launch can change it; a launch chooses only who collects it, whether a list of addresses, the pool itself, or nobody at all. On chains that support it a launch can also set its own buy and sell tax on top, which is why those two can differ. It is fixed when the token is created and cannot be raised afterwards, by the creator or by us.
- No transfer tax, no wallet cap, no per block limit. Nothing inside a Fizz token can make a trade fail.
Can a token reach other chains?
A Fizz token lives on the chain it was launched on, and for almost everybody that is the whole story. It can also be made reachable from another chain, and every token we launch already carries what that needs. It is something the platform can do, not a step anyone has to take, and it is not switched on yet.
The usual way to move a token between chains is a bridge, and bridges are where some of the largest hacks in crypto have happened. Instead we use Chainlink's Cross Chain Token standard, the same infrastructure large institutions use to move value between chains. Its registry and pool factory are open to anyone, so registering a token takes no permission and no queue.
How it works. Your tokens are locked in a Chainlink pool on the chain they were launched on, and only then does a matching amount appear on the other chain. Coming back burns them there and unlocks yours here. Nothing new is ever created on the home chain: the token has no way to mint. That is not a promise, it is the contract — there is exactly one mint in it and it runs once, when the token is born.
What that gives you, and what it does not. One supply across every chain, and every token in existence traceable to the one that was minted here. It does not give you one price: each chain has its own pool, so prices sit slightly apart and traders arbitrage the gap. And the address differs per chain — the registry links them, so it is the same token, but do not check an address you copied from one chain against another.
Why it is built in already. The hook cannot be added to a token after people own it — a launchpad that ships a plain token has locked its coins out of this forever. So every Fizz token carries it from birth, whether or not it is ever used. The remote side still has to be built and reviewed before anyone can, and we will switch it on one chain at a time.
What to watch out for
- • Memecoins are extremely volatile and speculative. You can lose your entire stake.
- • Only spend what you can afford to lose. Nothing here is financial advice.
- • Anyone can launch a token. A familiar name or logo means nothing. Do your own research.
- • Read the launch terms, the holders and the socials. Be cautious of tokens where the creator holds a large share.
- • The price bands make cheap accumulation expensive. They do not stop it. Do not size up because a token looks protected.
- • Fizz can't guarantee any token's value or that a project is legitimate.
- • Always confirm you're on the real site before connecting a wallet or signing.
