Wormhole v2 Testnet

This Wormhole testnet connects the following chains:

It runs the v2.1.1 guardiand reference implementation.

Important differences from v2

Wormhole v2 is a full redesign and not backwards compatible.

When it comes to guardiand operation, the basics stay the same - we observe events from various connected chains, sign them and broadcast the signature to the network. Here's the main operational differences compared to v1:

  • guardiand now has a data directory and is no longer stateless. guardiand will start maintaining local network state like a gossip address book, persisted signed VAAs and a high watermark to catch up on missed blocks. You do not need to back up the data directory, but it's recommended to copy it when migrating between servers - doing so will improve network health.

  • Terra is no longer optional - you need to connect a Terra node.

  • guardiand no longer sends on-chain transactions. This means that no wallets or funds are required anymore 🎉 It also means that the Rust agent is no longer required.

Network parameters

Gossip network name:

/wormhole/testnet/2/1

Gossip bootstrap node:

/dns4/wormhole-testnet-v2-bootstrap.certus.one/udp/8999/quic/p2p/12D3KooWBY9ty9CXLBXGQzMuqkziLntsVcyz4pk1zWaJRvJn6Mmt

gRPC-web/REST API:

https://wormhole-v2-testnet-api.certus.one

Guardian set

Current generation: 0, containing only the Certus One bootstrap node with the address 0x13947Bd48b18E53fdAeEe77F3473391aC727C638.

See v1.prototext 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 on how to set up a node. Example systemd unit file:
