One line of paired coins

Dollhouse has one chain. Every coin in it is paired with the coin before it, called its parent. The newest coin is the head coin, and each round, a timed contest between new coins, adds the next coin below it.
Coin #3’s pool holds #2, #2’s pool holds #1, and #1’s pool holds $DOLL. Every Dollhouse pool is priced in $DOLL or a chain coin. The chain starts at link one, the pool between $DOLL and coin #1. A coin’s price is quoted in its parent. When a coin’s price moves, traders who buy in one pool carry that move up to every coin above it. A coin that wins its round joins the chain and gets a numbered spot. Its number and parent are written on-chain once and stay fixed for good. While it is the head, the candidate coins entered in the next round are priced in it. From then on, it earns a part of the chain share on every coin launched after it.

Buy-side liquidity from every pool

Every pool keeps 0.075% of each trade, in the coin that pool is priced in. That money becomes single-sided buy liquidity just under the chain coin priced in that same coin. For a coin in the chain, that is its own pool. So the more a coin trades, the more buying sits under it. Candidates in a round are all priced in the head coin. Their 0.075% goes under whichever coin wins that round. Buy liquidity is placed in portions over several days. When sellers fill it, the coins it buys stay locked in the pool too, so everything placed there stays for good.

The chain share

The chain share is 40% of the 1% fee, and all of it becomes buy liquidity. Half of it goes under every earlier coin, from $DOLL down to the traded coin’s parent. Earlier coins share it unevenly, and $DOLL always gets about twice the newest coin’s part. The other half goes under the traded coin’s parent. During a round, every candidate’s parent is the head coin. So trading candidates builds buy liquidity under the head. Each coin’s part becomes buy liquidity in that coin’s own pool, just under its price. A round’s part always goes to the coin that won that round.
