Every order joins the set.
Buys and sells that arrive during a batch wait together. Nothing executes early, so landing in the first slot changes nothing.
a few slots · one set · cancel until it closes
Every buy and sell that lands in the same batch clears at one price. Being first buys nothing, so there is nothing to snipe and nothing to bundle.
On a normal launch the first transaction gets the best price, so bots race for block 0. A set has no first place.

a few slots · one set · cancel until it closes

When the batch closes, buys and sells cross first. Only the imbalance trades on the Meteora curve, and every order shares the price it lands on.
buys ⇄ sells · imbalance → curve · one price

The token's transfer hook refuses any trade on the curve outside a batch settlement. A sniper just joins the set and pays what everyone pays.
transfer hook · settle only · no block 0
Six people buy within a few slots. On a normal curve, arriving first decides the price. In a set, it decides nothing.

The opening auction collects every order before trading starts. Then a new batch opens every few slots.

Orders land in the open batch. Pull yours back at any moment until it closes.

A keeper settles the batch: buys and sells cross, the imbalance trades on the curve, one price for all.

Claim your tokens or SOL from the settled batch. Unfilled amounts come back to you.

Sets run on a Meteora bonding curve. When it fills, the token moves to a Meteora DAMM v2 pool, the batch rule lifts, and it trades like any other token.
A batch of slots. Every order that lands in it, buy or sell, settles together at a single clearing price instead of one by one.
There is no block 0 to win. The token's transfer hook only lets the Meteora pool move tokens inside a batch settlement, so an early transaction just joins the set and pays the same price as everyone.
Yes. Until the batch closes you can pull the order back and get your SOL or tokens returned in full.
As soon as the batch settles, usually a few seconds after it closes. Claim from Your orders; any unfilled part is refunded in the same transaction.
When the curve reaches 85 SOL, the pool migrates to Meteora DAMM v2 and the transfer hook is revoked. From then on the token trades freely on any Solana venue.
