Buying a share

Every venue on this chain sells you a token. You pick an amount of token, you get that amount of token, and what it stands for is your problem. After a dividend or a split that is a different quantity of company than it was the week before, and nothing on the screen says so.

Collapick takes the order in shares. You say two and a half shares of Apple; the order that reaches the pool is two and a half divided by the multiplier, because that is how many tokens stand for that many shares today. The division is the whole product. It is one line of arithmetic and nobody else on the chain does it.

What happens when you press the button

• 01Shares become tokens: tokens = shares ÷ uiMultiplier(), read live from the token contract.
• 02The venue is chosen: the deepest Uniswap v3 pool pairing that token with USDG, out of the four fee tiers.
• 03The pool is asked for a real quote. The router runs the swap inside an eth_call and reverts with the answer, so the number accounts for the ticks the order would cross rather than assuming the spot price holds.
• 04You approve exactly the amount the order needs. Not an unlimited allowance, and never one that outlives the trade.
• 05The swap goes through CollapickRouter with a minimum output and a deadline. Both are enforced on chain, which is the only place a slippage promise means anything.
• 06Your wallet signs. Collapick never holds the funds, never takes a fee and cannot move a token of yours.

The order is recorded after the fact so the operator can count orders, and the row is marked filled or failed only once the receipt has been read from the chain. What your browser believed at the time it signed is never treated as what happened.

What this does not do

• 01It is not a brokerage. You are trading a token in a pool, not buying stock from an issuer.
• 02It does not route across venues or split an order. One pool, one hop, chosen for depth.
• 03It cannot fill what the pool cannot fill. A large order moves the price, and the quote shows you by how much before you sign.
