# v3 coins: bridging a coin launched before Gap v4

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.

Every coin launched before Gap v4 is a v3 coin and stays one. Its token is its own LayerZero OFT on each of its chains, it keeps the v3 bridge price-gap fee exactly as it launched with it, and the shared v4 bridge never carries it. The sections that follow, up to the trading section, describe these v3 coins.
