# What changed from v3

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.

- One shared Pangea bridge on each chain for every v4 coin. A v3 coin keeps its own bridge. [Shared bridge →](https://www.pangea.trade/app/docs/v4#v4-shared-bridge)
- Both LayerZero and Hyperlane on every v4 coin. v3 is LayerZero only. [The two transports →](https://www.pangea.trade/app/docs/v4#v4-transports)
- Six chains: Elysium joins Ethereum, Base, BNB Chain, Robinhood Chain and Solana. [Chains and pairs →](https://www.pangea.trade/app/docs/v4#v4-chains)
- Chains can open later, and each chain's 1B is minted only when that chain opens. [Opening a chain later →](https://www.pangea.trade/app/docs/v4#v4-open-later)
- Any token can be the pair, on every chain. [Any pair, any token →](https://www.pangea.trade/app/docs/v4#v4-any-pairs)
- Launch from your own wallet with no launch fee. [Launch from your own wallet →](https://www.pangea.trade/app/docs/v4#v4-self-launch)
- The creator moves the creator role at once, or renounces it. [Handing over →](https://www.pangea.trade/app/docs/v4#v4-handover)
- Holder rewards: a reward token and a share set per chain, and one minimum holding for all chains at launch, changeable per chain after launch. [Tokenomics →](https://www.pangea.trade/app/docs/v4#v4-tokenomics)
