How tonkfun.fun works.

What tonkfun.fun is

A token terminal for Solana and Robinhood Chain, in five screens:

Explore

Every new token across both chains, from the major launchpads, each with its Mission score.

Swap

Trade tokens by the best route found, signed in your own wallet.

Bridge

Move major assets between 17 networks, into Robinhood Chain above all, by the best live route.

Portfolio

Your wallets' holdings and activity, read live from the chains. It only reads: it never signs or sends.

Launch

The Creator Studio, where you launch a token on tonkfun.fun's own launchpad on Robinhood Chain.

Launching a token

Launch is invite-only for now: only invited creators can launch from this site.

Tokens launch from the Creator Studio, on Launch, in four steps:

Token & basics

The name, ticker, description and links. The name and ticker are permanent; the description and links can be edited later.

Locked Mission

Whether to lock part of your dev buy, how much and for how long.

Mission economics

Your Crew Rewards and Creator Rewards, on top of the 1% protocol fee.

Token Agent

An optional persona and mission brief for your token, stored on-chain with it. Its chat is a preview for now.

The dev buy

You can buy your own token inside the launch transaction. That dev buy is exempt from the launch-block tax. It pays the 1% protocol fee and your own Creator fee, which comes straight back to you, but no Crew fee, since nobody else holds the token yet. You need a dev buy to lock tokens, and a lock to set Creator Rewards above 0.5%.

The review

Before anything is sent, a final review shows everything you're about to launch. You pay the launch fee and the dev buy in one transaction, signed in your own wallet, and the launch counts once its receipt is confirmed.

Token images come later. For now a token shows its first letter.

The bonding curve

Every tonkfun.fun token starts on its own bonding curve. The launchpad is the market: you buy from the curve and sell back to it, and the curve sets the price. Each buy raises it, and each sale lowers it.

The price comes from virtual reserves of ETH and tokens, whose product stays the same through every trade. They're virtual because the curve starts with no real ETH: the starting reserve only sets the starting price.

Every token has a fixed supply of 1 billion, all minted to the launchpad at launch: 800 million are sold on the curve, and 200 million are kept back for its pool. Nobody can mint more or freeze transfers. A sale pays out at most the ETH really in the curve.

These settings apply to new launches. Each token keeps the reserves it launched with.

Graduation

When the curve has sold all 800 million tokens, the token graduates in that same transaction. The buy that completes the curve is cut to exactly what it needs, and the rest of its ETH is refunded.

The curve's ETH, less 1.5% (1% to tonkfun.fun and a 0.5% bonus to the creator), goes with the 200 million tokens into a new Uniswap v4 pool, ETH against the token. Curve trading ends there; from then on the token trades in its pool.

The pool's liquidity is locked for good: the migrator holds the position and can only collect its fees, never withdraw it.

Only the migrator can open that pool. A guard on it turns anyone else away, so nobody can open it early at a rigged price. Trading in it is standard Uniswap v4.

Fees

Launching costs a one-time launch fee, paid to tonkfun.fun's treasury.

On every curve trade

Every buy and sale on the curve pays its fee in ETH: a fixed 1% protocol fee to tonkfun.fun, plus the token's Crew Rewards for its holders and Creator Rewards for its creator.

Crew and Creator Rewards share at most 4%, so the fees on a curve trade never come to more than 5% in all. Crew Rewards are either off or 1% or more. The creator sets both at launch, and they never change.

Creator Rewards tiers

• Up to 0.5%: no lock needed.
• Up to 2%, Standard: 50% or more of the dev buy locked for 30 days or more.
• Up to 4%, Ironclad: 80% or more of the dev buy locked for 90 days or more.

Above 0.5%, the lock must also hold at least 10 million tokens: 1% of supply.

The Crew fee is only charged once eligible holders own at least 10 million tokens, as Crew Rewards explains below.

Referrals

A curve trade made through someone's referral link pays them 25% of the protocol fee: 0.25% of the trade, out of tonkfun.fun's 1%, not on top of it. Your own link earns nothing on your own trades, and the launch fee and the creator's dev buy carry no referral share.

At graduation

1.5% of the curve's ETH: 1% to tonkfun.fun and 0.5% to the creator as a graduation bonus.

After graduation

The pool's fee is the token's full fee: 1% plus its Crew and Creator Rewards. A token with 2% Crew Rewards and 1% Creator Rewards has a 4% pool fee.

The pool's fees build up until someone shares them with Share pool fees on the token page. Anyone can, for just the network fee. The ETH side is split in the same proportions as the fee, between tonkfun.fun, the Crew and the creator, and the token side is sent to the dead address, out of circulation.

Locks

A creator can lock part of their dev buy, written into the launch itself. The launchpad holds the locked tokens, and nobody can take them early, the owner included.

Time-lock

Everything unlocks at the end.

Linear vesting

Tokens unlock continuously, second by second, until the end.

No lock

The creator's tokens are theirs at once.

A lock needs a dev buy, covers 50% to 100% of it, and runs for 7 days or more.

Unlocked tokens stay in the launchpad until the creator claims them on the token page.

Extending a lock

A lock can be made longer, by 7 days or more at a time, but never shorter. The new end counts from the old one, or from now if the old end has passed.

Extending a linear vest restarts it: what has already unlocked stays claimable, and only what hasn't vests again, from now to the new end.

The Locked badge

Crew Rewards

When the creator turns them on, Crew Rewards share 1% to 4% of every curve trade with the token's holders: in ETH, and in proportion to what each holds.

Every holder is eligible except the launchpad itself (which holds the unsold curve tokens and the creator's locked ones), the token's own contract, its Uniswap pool, the burn addresses, and any contract the owner excludes, such as a vault. Only contracts can be excluded, and only for good.

The 10 million minimum

No Crew fee is charged until eligible holders own at least 10 million tokens: 1% of supply. Until then, curve trades pay only the protocol fee and Creator Rewards, so a tiny holding can never collect the whole Crew fee.

Getting paid

Rewards build up as trades happen. They're sent to your wallet automatically whenever your balance of the token changes, and anything unpaid can be claimed on the token page at any time.

After graduation

The Crew's share of the pool fees reaches holders the same way, each time someone shares the fees. If eligible holders own less than 10 million tokens at that moment, it goes to tonkfun.fun's treasury instead, so later holders never inherit it.

The launch-block tax

In the launch block and the next one, every buy pays a 99% tax, the creator's own later buys included. Only the dev buy made inside the launch transaction is exempt.

The tax is burned: sent to the dead address, where nobody can ever spend it, tonkfun.fun included. The other 1% of the buy goes through the curve as usual.

It keeps bots from sniping a token the moment it launches. The blocks are Robinhood Chain's own, counted by the chain, not by a timer.

To spare you the tax, this site sends no buys until two blocks after launch. If a buy doesn't go through in the first seconds, wait a moment and try again.

Mission score and badges

Every token on Explore has a Mission score from 1 to 99, worked out from what the chain and the market show. It errs on the side of caution. It's a guide, not advice: no score makes a token safe to buy.

• Safe75 and up: the checks turned up little to worry about.
• Caution50 to 74: something calls for a closer look, such as a token under ten minutes old or a creator buy that isn't locked.
• RiskyUnder 50: clear warning signs, such as a creator who can still mint or freeze the token, a few wallets holding most of the supply, or a pool too thin for its price.

What it weighs

It starts at 50, then adds points for good signs and takes them away for warnings: whether anyone can still mint or freeze the token, whether its pool's liquidity is locked or burned, the creator's buy and how much of it is locked, Crew Rewards of 1% or more, how concentrated the holders are, the last hour's trading and price, the day's volume, the pool's depth, and the first ten minutes, which are too early to tell.

A tonkfun.fun launch is scored from its own chain facts: a fixed supply nobody can freeze, the creator's dev buy and lock, its Crew Rewards and its age.

Badges

Safety

Beta: there has been no outside audit. The launchpad's contracts have had internal reviews only, so using them carries smart-contract risk. Only put in what you can afford to lose.

What was checked, and how to report a flaw: the Security page

Starting limits

The owner sets the starting ETH reserve for new launches, between 1 and 100 ETH. A curve never holds more ETH than it takes to graduate, so that reserve also limits how much ETH any one curve can hold.

Launch is invite-only for now.

Who controls what

The contracts are owned by the team's Safe account. The owner can pause and unpause the launchpad, set the launch fee (up to 0.05 ETH) and the starting ETH reserve, choose the treasury that receives fees, and exclude a contract from Crew Rewards.

The owner can't take the ETH in a curve, a creator's locked tokens or a pool's liquidity. It can't change a token's fees or lock, or the migrator, which was set once for good, and it can't give up ownership.

If the launchpad is paused

A pause stops new launches and buys on the curve. Selling to the curve always stays open: the contract's sell can't be paused. Claims, withdrawals, lock extensions and edits keep working, and graduated tokens keep trading in their pools.

The contracts

On Robinhood Chain mainnet: each contract, its source verified on Blockscout, then the Safe account that owns them.

FAQ

Why didn't my buy go through in the first seconds?

In the launch block and the next one, every buy except the creator's dev buy loses 99% to the launch-block tax, so this site sends no buys until two blocks after launch. Wait a moment and try again.

When does my token graduate?

The moment its curve has sold all 800 million tokens. The bonding curve section shows how much ETH that takes for a new launch today.

Where do the fees go?

The launch fee and the 1% protocol fee go to tonkfun.fun's treasury, less a referrer's 25% share of the protocol fee. Crew Rewards go to the token's eligible holders and Creator Rewards to its creator. At graduation, 1% of the curve's ETH goes to the treasury and 0.5% to the creator.

Can the creator sell their locked tokens?

Not before they unlock. The launchpad holds them, the creator can claim only what has unlocked, and a lock can be extended but never shortened.

Can I always sell?

To the curve, yes, even while the launchpad is paused: a sale pays out at most the ETH really in the curve. After graduation, you sell in the token's pool.

Why is there no Crew fee on my trade?

The Crew fee starts once eligible holders own at least 10 million tokens, 1% of supply. Until then, trades pay only the protocol fee and Creator Rewards.

How do I get my Crew Rewards?

They're sent to your wallet whenever your balance of the token changes. Anything unpaid can be claimed on the token page at any time.

Is the liquidity locked after graduation?

Yes, for good. The migrator holds the pool position and can only collect its fees: nobody can withdraw the liquidity, tonkfun.fun included.

Can a token's fees or lock change after launch?

The fees never change, and a lock can only be made longer. The creator can edit the description, links and agent brief; the name and ticker stay as they are.

Has the launchpad been audited?

Not by an outside auditor: it has had internal reviews only. The Security page lists what was checked.
