Supply you keep
Declares on chain the most of a new token's supply the creator may hold at launch.
Where it runs
Launch
An option of the launch, not of each swap.
Status on reel
Launch option
An option of reel's launch flow, fixed when the launch is created (PROGRAM.md §5, §7).
Set by
You, at launch
Launch · Live
What it does
The most of a new token's supply the creator may keep when the launch finalizes: dev buys plus supply no pool took. The launch fails if it is exceeded. With a dev buy, 5% applies on top.
How it works on reel
max_retained_bps at LaunchCreate. LaunchFinalize checks escrow_left + dev_bought ≤ max_retained, and ≤ 5% with a dev buy (RetainedAboveCap); LaunchReturn later sends the escrow's leftover to the creator.

Set on the launch, in the Launch account or a launch instruction, not in PoolParams.
| Setting | Min | Default | Max | What it does |
|---|---|---|---|---|
Most you keep max_retained_bps | 0% | 100% | 100% | Of a new token's supply, dev buys plus what no pool took, checked at finalize. 10,000 is no cap; existing-token launches are forced to 10,000.With a dev buy, at most 500 (5%) applies on top. |
Fees and who's paid
Paid to
Nobody: it charges nothing.
Protocol share
reel takes no share of it.
Requires and can't be combined with
Requires
No other block.
- New tokens only
Can't be combined with
Nothing: it sits beside any block.
Worked example
Supply 1,000,000,000 with a 2% cap: if the pools take 985,000,000 and the dev buy brings 10,000,000, the creator holds 2.5% and finalize fails.
Solana notes
It works as on hookr; amounts are in SOL or the pool's quote, and times in seconds.

Other blocks in Team tokens
Dev buy and lock
LAUNCHOne first buy per pool inside the launch, then the launch liquidity stays locked.
Liquidity lock
LAUNCHKeeps the launch liquidity in its pools for a set time, or hands the launch to a lock.
Vesting Milestone
LAUNCHLocks a team allocation that vests after a cliff, then linearly.
Dev Drip
LAUNCHReleases the creator's own allocation through the pool, a slice per window.
