bundle.ninja Documentation
bundle.ninja runs scheduled token launches on Solana. A creator picks a launch time, buyers reserve seats in advance, and everyone goes in together the moment the token is created — so your share is decided by your bid instead of by how fast your bot is.
The whole app is two pages: the homepage, where launches are listed and joined, and your dashboard, where your wallets, launches and rewards live. You sign in with a Solana wallet (Phantom, Solflare or Backpack) — there is no email or password.
How a launch works
- Scheduled. The creator sets a launch time, at least 30 minutes ahead, and funds the launch from their dev wallet.
- Open for seats. The launch appears under Upcoming on the homepage. Anyone can take a seat by placing a bid and choosing how much SOL that seat will buy. A launch has up to 50 seats.
- Auction closes 5 minutes before launch.At that point the seat list is final, each bid is charged, and every seat’s exact token amount is calculated and recorded.
- Launch.The token is created and the group buys straight away. The creator’s own buys happen inside the very same transaction that creates the token, so nothing can get in front of them.
What your bid does
Your bid decides your rank, and rank decides how many tokens you get for your money — seat 1 gets a better rate than seat 2, which gets a better rate than seat 3, and so on. The amounts are worked out when the auction closes and written down before the token exists, so you are not racing the other buyers in the group either.
- Minimum bid: 0.02 SOL
- Maximum a single seat can buy: 1 SOL
- The bid is the fee — it buys the seat and sets the rank, and it is only charged when the auction closes
- Leaving before the auction closes is free — nothing has been charged yet
- You can hold several seats in one launch, one per trading wallet
Why the token address stays hidden
A launch’s contract address is not shown to anyone — including the creator — until the moment it launches. If the address got out early, outsiders could prepare a purchase for it in advance and land right behind the group. It becomes visible as soon as the launch is done.
Creating a launch
Press Create Launch on the homepage. You will need:
- Token identity— name, ticker, an image, and optionally a description and website / Telegram / X links. These are pinned to IPFS and become the token’s metadata on pump.fun.
- Your own buy — how much SOL your dev wallet buys at creation, plus optionally up to 5 of your own trading wallets buying alongside it (max 1 SOL each). They buy from their own balance.
- Launch time — at least 30 minutes ahead. This is re-checked when you fund, so a draft left sitting too long has to be rescheduled.
Creating a launch is free. The only SOL you need is the funding itself: your own buy plus roughly 0.055 SOL that covers creating the token on Solana and the network fees.
Your dev wallet is the address that creates the token, which means pump.fun’s creator rewards from trading accrue to you — see below.
Joining a launch
Click any launch under Upcoming. Pick which of your trading wallets take seats, set a bid and a buy amount for each, and confirm. Each wallet needs enough SOL to cover its bid, its buy, and about 0.01 SOL kept back for network fees.
You can raise a bid or add wallets any time before the auction closes. Once it closes the launch shows the final ranking instead of a join form.
After a launch lands
Open the token from the homepage or your dashboard to see its live chart and market cap, what each of your wallets holds, what it cost, and the profit or loss on it. You can sell any amount from 25% to 100% per wallet straight from that window.
The same window shows the book — every seat in that launch with its rank, bid and allocation. It is public once the launch is done, so anyone can check that the ladder was honoured.
Your dashboard
- Dev wallet— the address that creates your tokens. Only fund it if you want to launch something; taking seats in other people’s launches does not use it. Withdraw from it any time.
- Trading wallets — up to 20 separate wallets used to take seats. Generate them, fund them from your dev wallet, and sweep them back out whenever you like.
- Mixing wallet — fund it, then send SOL from it to your trading wallets through FixedFloat, so the payouts arrive from the exchange instead of as direct transfers. Minimum 0.1 SOL per wallet.
- Creator rewards — pump.fun pays the creator of a token a share of every trade on it. Your claimable balance shows here; you keep 70% of what you claim.
- My launches and joined bundles — everything you have created or taken a seat in.
What it costs
- Creating a launch: free
- Funding a launch: your own buy plus about 0.055 SOL for creating the token
- Taking a seat: your bid, plus whatever you choose to buy with
- Everything else:ordinary Solana network fees, and pump.fun’s own trading fee
Worth being clear about
bundle.ninja changes how you get into a launch. It does not make any token a good investment. Newly created tokens are extremely risky and most lose most of their value. Never put in money you cannot afford to lose.
