# Wormhole v2 Mainnet

Wormhole mainnet connects the following chains:

- Solana [Mainnet Beta](https://docs.solana.com/clusters#mainnet-beta).

- Ethereum Mainnet.

- Terra Columbus mainnet.

- Binance Smart Chain mainnet.

It runs the [v2.5.0](https://github.com/certusone/wormhole/releases/tag/v2.5.0) guardiand reference implementation.

## Network parameters

Gossip network name:

    /wormhole/mainnet/2

Gossip bootstrap node:

    /dns4/wormhole-mainnet-v2-bootstrap.certus.one/udp/8999/quic/p2p/12D3KooWQp644DK27fd3d4Km3jr7gHiuJJ5ZGmy8hH4py7fP4FP7
