How ditch.fun works
One way to launch. Built so the first seconds go to people, not bots.
Overview
Most launches are decided in block zero: bots and bundles buy first and dump on everyone after. ditch.fun opens every coin the same way, so that stops paying.
- A coin trades the second it launches.
- Snipers pay: the fee starts at 75% and melts to 0.75% in 3 seconds.
- For its first 45 seconds a coin trades only on ditch.fun, and every buyer is checked. Then it trades everywhere.
- The creator can buy at most 5% of their own coin, enforced on-chain.
- Sells always work, everywhere, from the first second.
How a launch opens
Every launch opens the same way
Sniper fee
75% → 0.75% in 3s
Where it trades
unlocks at 45s
Bots and bundles are turned away at the door. Sells always work.
| When | What happens |
|---|---|
| 0s | The coin is live. Anyone can buy it on ditch.fun. |
| 0–3s | Sniper fee: 75% → 16% → 3.5% → 0.75%. |
| 0–45s | Only on ditch.fun. Buys from Axiom, Jupiter or a bot are refused on-chain. |
| 45s | The gate unlocks. The coin trades everywhere. |
| 85 SOL | Graduates to Meteora DAMM v2, with the liquidity locked forever (stock pairs graduate at the same dollar value). |
Sniper fee
For the first 3 seconds the pool charges a fee that starts at 75% and falls every second. It is Meteora's own fee scheduler, set when the coin is created and the same for every coin. Nobody can change it.
| Time after launch | Fee |
|---|---|
| 0s | 75% |
| 1s | 16% |
| 2s | 3.5% |
| 3s and after | 0.75% |
What 1 SOL buys: in block zero about 9.3M tokens, with 0.75 SOL going to fees. After 3 seconds, about 36.1M tokens. Waiting three seconds gets you 3.9× more.
Only on ditch.fun
For its first 45 seconds a coin can only be bought here. Every coin carries the gate: a small on-chain program (a Token-2022 transfer hook) that refuses any buy without ditch.fun's signature. We sign a buy only after checking the wallet, and turn away:
- wallets funded by the coin’s creator,
- wallets that share a fresh funder with another buyer,
- more than 3 wallets from one connection,
- brand-new wallets with no history.
Buys from Axiom, Jupiter, a Telegram bot or a script fail on-chain in that window. After 45 seconds the gate stops checking and the coin trades everywhere.
Approvals only come from this website. A request must come from our own pages and pass a quick human check (Cloudflare Turnstile), and each wallet gets at most 2 approved buys in the first 45 seconds, each connection 4. An approval is our signature on the exact transaction we built, so it can't be moved to another buy, wallet or app.
The creator's cap
The gate also knows who launched the coin: any buy that would leave the creator's wallet holding more than 5% of the supply is refused, from any app, for as long as the coin is on the curve. Sells are never refused.
What the gate can't do
- Block a sell or a transfer. It never looks at them.
- Stay on longer. The 45 seconds are written on-chain at launch, and the program refuses anything over 60.
- Hold funds. It has none, and no admin.
- Outlive graduation. Meteora removes it from the coin when the coin graduates.
Launching a coin
- 1Name it. Name, ticker, image, and optionally a description and links.
- 2Add hooks (optional). Commit a share of your creator fees to buyback & burn, holder rewards or a donation. Hooks are public, pinned to IPFS, and every claim is audited against them.
- 3Add vesting (optional). Your stock options: up to 10% of supply for you, locked until after graduation, then released over a period you choose.
- 4Launch. Sign two transactions. It costs about 0.04 SOL in rent. There is no launch fee.
Everything else is the same for every coin: 1B supply, the curve, the sniper fee, the gate and graduation. Launch a coin →
Stock pairs
A coin trades against SOL by default, or against a tokenized stock: NVIDIA, Tesla, Apple, the S&P 500 and more, as xStocks issued by Backed. Buyers pay in the stock, fees build up in the stock, and holder rewards and donations pay out in it. Everything else is the same: the 75% sniper fee, 45 seconds only on ditch.fun, locked liquidity.

Good to know
- To buy, you need the stock in your wallet (and a little SOL for network fees).
- Graduation targets are set to about the dollar value of 85 SOL, in each stock.
- Backed, the issuer, can pause or claw back xStock transfers. A pause would pause trading in coins paired with that stock too.
- xStocks are not offered everywhere (for example, not to US persons). Check the rules where you live.
No copycats
A coin can't take the ticker or name of a coin that already exists: one already on ditch.fun, an established Solana token (verified on Jupiter, or worth over $1M), or one of the stock pairs. The first coin keeps its ticker.
- Matching ignores case, $ signs, spaces and accents, and catches digits posing as letters: PEP3 is PEPE, B0NK is BONK.
- The launch form checks as you type, so you never pay to launch a copy.
- Copies made outside the app fail the “original” check and are never listed on ditch.fun.
Fees
| Trading fee | 0.75% once the sniper seconds pass |
| Who gets it | Creator 40% · ditch.fun 40% · Meteora 20% |
| After graduation | 0.25% pool fee. Locked-liquidity fees go 50% to the creator, 50% to ditch.fun. |
| To launch | Free (about 0.04 SOL in rent) |
| To graduate | Free |
Creators claim their fees from the Creators page, whenever they like.
Graduation
When 85 SOL is in the curve (or the same value in the coin's stock), the coin moves to a Meteora DAMM v2 pool. All of its liquidity is locked forever: nobody can pull it. You can keep trading it here, or anywhere else.
Bundle radar
Every coin gets a grade from A to F from its first buyers: wallets that share a funder, Jito bundles, wallets linked to the creator, and how much supply they hold. You see it on the board and on the coin's page.
Checks
Before a coin is listed, we rebuild its on-chain config with our launch builder and it must match byte for byte. That covers the fixed 1B supply, no mint authority, the sniper fee, the gate window, the locked liquidity, no dev discount and more. Every coin page shows its checks. A coin that fails one isn't listed.
FAQ
Can I buy on Axiom or Jupiter in the first 45 seconds?+
No. Buys from anywhere else fail on-chain until the gate unlocks. Buy on ditch.fun, or wait 45 seconds.
Can I always sell?+
Yes. Anywhere, any time, from the first second. The gate never looks at sells or transfers.
My buy was turned away. Why?+
In the first 45 seconds we refuse wallets that look like bundles: brand-new wallets, wallets funded by the creator, wallets sharing a fresh funder, or too many wallets from one connection. After 45 seconds anyone can buy.
Does the creator get a cheap first buy?+
No. The creator buys like everyone else and pays the same sniper fee, and the gate refuses any buy that would leave the creator’s wallet holding more than 5% of the supply. A launch can’t bundle a dev buy.
Can a bot get buys out of your API?+
Only as a person would. In a coin’s first 45 seconds the chain refuses any buy without our co-signature, and we only co-sign requests from our own pages that pass a human check, for wallets that pass the checks above, at most 2 buys per wallet. The co-signature covers the exact transaction we built, so it can’t be reused for another buy.
Who gets the sniper fee?+
It’s a normal trading fee, just bigger, so it splits like one: creator 40%, ditch.fun 40%, Meteora 20%.
What if ditch.fun goes down during a launch?+
Then nobody can buy that coin until its 45 seconds are up, and after that it trades everywhere as normal. Sells keep working throughout.

Risks
- Memecoins are risky. Only trade what you can afford to lose.
- ditch.fun is non-custodial: we never hold your keys or your coins.
- No launchpad can stop one person running many wallets. We price the first seconds against snipers, turn the obvious bundles away for 45 seconds, and show the rest on the radar.
- The gate program is open source and tested against Meteora’s real programs. It has not had an external audit yet.
- Stock-paired coins also carry the stock issuer’s risk: Backed can pause or claw back xStock transfers.
