+# Wormhole v2 Mainnet
+
+This Wormhole testnet 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 [v2.2.0](https://github.com/certusone/wormhole/releases/tag/v2.2.0) 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/12D3KooWL6xoqY8yU2xR2K6cP6jix4LnGSrRh94HCKiK371qUFeU

+
+The Terra deployment is still in progress. Specify `--terraContract "pending"` in the meantime - the Terra
+watcher will fail, but all other chains will work.
+
+## Guardian set
+
+Current generation: **0**, containing only the Certus One bootstrap node with the
+address `0x58CC3AE5C097b213cE3c81979e1B9f9570746AA5`.
+
+See [v1.prototext](guardianset/v1.prototxt) for the first guardian set update that will be executed once everyone's
+node on the network is live.
+
+## Example command line options
+
+Refer to the [operations guide](https://github.com/certusone/wormhole/blob/dev.v2/docs/operations.md) on how to set up a node.
