# Gap v4: handing over the creator role

Pangea v3: every new launch, stock pairs and questions. Every launch since 2026-11-02 is a v3 launch, made by factory v3 on all five chains. This tab is everything new in v3: the factories, the fee hook, launch buys, stock pairs, the bridge price-gap fee, Solana, the security model, and plain-language questions and answers at the end. Bridging, routes and the APIs are in the V2 tab and hold for v3 except where this tab says otherwise. A Gap v4 coin lives on up to six worlds: Robinhood Chain, Base, Ethereum, BNB Chain (BSC), Solana and Elysium. The four EVM chains and Solana carry LayerZero and Hyperlane; Elysium (chain id 99901, gas in HYPE) carries Hyperlane only.

- The creator role is the wallets that receive the creator fees, one for the EVM chains and one for Solana. The current creator moves it themselves, on the coin's home chain, in one transaction, at once. There is no propose and accept step.
- The change is then copied to every other open chain by a bridge message. The profile page offers one push per other open chain, priced first, and whoever sends a push pays its transport and delivery fee. Until a copy lands, seconds to minutes, that chain still pays the old wallet.
- The creator can also renounce the role, at once, after typing the coin's symbol to confirm. The creator share of the fees is then burned, and anyone may ask the home chain to authorise opening the coin's remaining chains.
- The platform can still move the role, as for v3 coins: it names a new wallet and that wallet accepts. This also ends a renounce. A creator's own moves cannot cancel it, so a stolen creator wallet cannot block a recovery.
- An authorisation to open a chain given before a handover or a renounce stops counting once the new role reaches that chain; the new creator gives it again.
- v4 coins have no separate buy or sell fees and no launch tax.

## From a program

`POST /api/v1/launch/v4/handover` builds the move or the renounce for the current creator's own wallet, on an EVM-home coin's home chain. A Solana-home coin's handover is a Solana instruction signed on the coin page: the API answers 409 for it. See Gap v4 from a program.
