# How pricing works

Pangea v4: how a coin launches today. Every new launch is a v4 launch. A v4 coin lives on up to six chains: Robinhood Chain, Base, Ethereum, BNB Chain (BSC), Solana and Elysium. The four EVM chains and Solana carry LayerZero and Hyperlane; Elysium carries Hyperlane only. This tab is all of v4: creating a coin, chains and pairs, fees and holder rewards, opening a chain later, handing over, launching from your own wallet, the Bundle Kit, bridging, contracts and the API. Coins launched before v4 are in the v3 and v2 tabs.

A coin on several chains is one coin. Its price on each chain comes from that chain's own pool, and moving it between chains never creates value out of a price gap.

## What you set

- The chains it lists, and which of them open now. A chain left closed can be opened later by anyone, at the price they pick, with liquidity of their own if they want.
- The opening price on each chain you open, and an optional first buy of your own.
- How it moves between chains: LayerZero, Hyperlane or both. A chain that has only one of them, such as Elysium, makes the coin use that one.
- Chains and transports are set for good at launch. Nobody can add a chain to the coin later.

## What keeps one price

- Buying on one chain and moving it to another is credited at the price you actually paid, plus a small margin and the move's real cost. The margin is smaller where the destination pool is deeper.
- Moving coins you already hold is priced at the lowest price of the last half minute, so a pump right before the move gains nothing.
- Anything a move would credit above that price is burned, never created. That is what holds the chains together without an oracle.
- A move waits, rather than landing at a guessed price, when a pool cannot be read, or when it would land below the least you asked for.

## What you pay

- Opening chains yourself: no launch fee. You pay each chain's network cost from your own wallet.
- Letting us open them: one launch fee, shown before you pay, in the coin you pay with. It covers the networks, including Solana's.
- Trades pay the coin's trading fee, shared between you and Pangea as the launch form shows.
