Plan your sale

Every setting here is fixed at creation and cannot change later.

1. The coin

• A new coin with zero supply. The sale mints the full supply itself. A coin that has minted anything cannot be used.
• Registered in Sui’s coin registry with its final name, symbol, decimals, and icon. They show in wallets and on the pool and cannot change.
• Total supply. The number of tokens that will ever exist.
• Fixed or burn-only. Either the supply never changes, or holders can burn tokens to reduce it. Nobody can mint more.
• Quote coin. The coin buyers pay with, such as SUI. Blast decides which quote coins sales may use.

2. The supply split

The shares must add up to exactly 100%.

Share	Who receives it	Rules
Buyers	Everyone who commits, pro rata	Required, more than 0
Liquidity	The launch pool	Required, more than 0
Blast	Blast’s token fee	Set by Blast, may be 0
Recipients	Treasury, team, advisors, and anyone else you name	Up to 64 wallets, each optionally vested

3. The raise

• Raise target. The quote coin the sale must reach to launch. Otherwise everyone is refunded.
• Raise split. At launch the target is divided between your raise recipients (up to 64, each optionally vested), Blast’s raise fee, and the pool. The pool gets whatever is left and must get something.

Only the target is split. Anything committed above it is refunded to buyers.

4. Price

Your choices produce two prices:

• Presale price = raise target ÷ buyers’ tokens
• Launch price = quote coin in the pool ÷ tokens in the pool

If the launch price is below the presale price, buyers start at a loss. Most teams set the pool’s shares so it is at or above the presale price. Try your numbers in the price simulator.

Example

Supply of 1,000,000,000 tokens. Raise target of 100,000 SUI.

• Buyers get 40% of supply (400,000,000 tokens). Presale price: 100,000 ÷ 400,000,000 = 0.00025 SUI.
• The pool gets 20% of supply (200,000,000 tokens) and 60% of the raise (60,000 SUI). Launch price: 60,000 ÷ 200,000,000 = 0.0003 SUI, 20% above the presale price.
• The other 40% of supply and 40% of the raise go to your recipients and Blast’s fees.

5. Timing

• Start time. When commitments open. You can publish the sale earlier so people can read the terms.
• Duration. How long the window stays open. A hard-capped sale can end sooner if you choose to close it when full (see the hard cap).
• Liquidity window. How long after the sale ends a funded sale can still launch before anyone may cancel it and refund buyers. At least seven days. Launch normally follows the window immediately, so this is a safety net for buyers.

6. Who can buy

Choose one.

Open sale. Anyone can join.

• Wallet cap: the most one wallet can commit.
• Minimum: the least one wallet’s total can be. No higher than the wallet cap.
• Participant limit: up to 65,536 wallets.
• Minimum × participant limit must reach the raise target, so the sale cannot fill with tiny wallets and never reach its goal.

Allowlist sale. Only listed wallets can join, each with its own cap. Caps can be equal, tiered, or custom. Up to 65,536 wallets. No minimum.

7. The no-cap phase (optional)

Lift wallet caps for the last part of the window to help the sale fill. The contract calls this the uncapped phase. It only lifts caps; whether the sale stops at its target is the hard cap’s job.

• When: how long after the start the phase begins.
• Who: wallets that were already eligible, or anyone. Opening it to anyone requires a participant limit and minimum for the extra wallets, sized so the raise can still be reached.

8. The hard cap (optional)

By default a sale keeps accepting coins past its target and fills every buyer at the same rate. A hard cap instead stops the sale at its target, first come, first served. Each commitment takes only what is left and the rest goes straight back to the buyer. A hard cap does not lift wallet caps.

• From when: how long after the start the hard cap begins. Before then, the sale accepts coins past the target as usual. It must begin before the window ends.
• Close when full: whether the sale ends, and can launch, as soon as it reaches its target, or keeps running to its end time.

Common choices:

You want	Set
Everyone filled at one rate for the whole window	No hard cap
First come, first served, within wallet caps	A hard cap from the start
First come, first served, without caps	A no-cap phase and a hard cap, both from the start
A capped round where everyone gets the same rate, then a first-come round without caps	A no-cap phase and a hard cap from the same time

Closing when full

A sale that closes when full can launch in the same moment it fills. Whoever fills it can then also be the first to buy in the new pool. The launch price is the same either way. If you want the pool to open at a public, announced time, choose not to close when full.

9. Buyer vesting (optional)

Buyers’ tokens unlock over time. You set a cliff, a step length, and a number of steps. Each buyer’s schedule starts when they claim.

10. The pool

• Exchange: Cetus or Bluefin, fixed at creation.
• Fee tier: the trading fee the pool charges. Pick it with the Blast team; your developer turns it into the exchange’s settings.
• On Cetus, the quote coin must be allowed by Cetus at that tier. On Bluefin, the coin’s symbol must be 32 bytes or fewer (32 plain letters).

11. Trading-fee split

After Blast’s share, the pool’s trading fees are split between:

• up to 16 fee recipients, which can include you, paid directly each time fees are collected;
• a holder allocation, whose quote-coin part funds rewards to your coin’s holders. Its sale-token part goes to Blast’s governed treasury.

The two must add up to 100%. Fee shares cannot vest. See Fees and revenue.

12. Partner (optional)

If a Blast partner referred you, the sale can name that partner at creation only. The partner earns a cut of Blast’s fees, never of yours.
