Opening price check
Fails the launch if a pool opens too far from pool 1's price.
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
Each pool after the first must open within a tolerance of pool 1's price, converted through a reference pool. It catches a wrong opening price; it isn't an oracle.
How it works on reel
opening_tolerance_bps (1 to 1,000; 0 = off) is checked at LaunchFinalize against live reel reference pools (OpeningOutsideTolerance).
Settings · 1
Set on the launch, in the Launch account or a launch instruction, not in PoolParams.
| Setting | Min | Default | Max | What it does |
|---|---|---|---|---|
Tolerance opening_tolerance_bps | 0% | 0% | 10% | Each later pool must open within this of pool 1's price, through a live reel reference pool. 0 = off. |
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.
- Two pools or more
- A live reel pool pairing each later quote with pool 1's
Can't be combined with
Nothing: it sits beside any block.
Worked example
A 1% tolerance: pool 1 opens at 0.00001 SOL, so pool 2 must open within 1% of that in USDC, converted through a live reel SOL/USDC pool.
Solana notes
Reference pools must be live reel pools.
