The kept pool.
When a pool opens, the curve's liquidity stays in the hook as protocol-owned liquidity. No function withdraws it.
It is shown separate from the fee split because it is depth, not a price. Green marks the pool.
Shown separately · depth, not a price
The pool is kept. No function withdraws it.
When a pool opens, the curve's liquidity stays in place as protocol-owned liquidity. It is separate from the four fee buckets. Green marks the pool.
What is in it
The hook seeds the position once, at the open, with the quote the curve collected and the token reserve it held back. The position sits on the same PoolId the token launched on.
What the toll does
The toll does not go into the pool. The four buckets take all of it, and the pool's own LP fee is zero. The buyback share buys the UNTOLL token, so it leaves this pool too.
Bounds A pool is kept only if its token reaches the open. It is per-asset, not a reserve anyone can redeploy.
