Syncing Mainnet Wormchain

Sync From Snapshot

Build Latest Wormchain Release

# checkout git repository
git clone https://github.com/wormhole-foundation/wormhole

# checkout latest release (v2.24.2-wormchaind at time of writing)
cd wormhole
git checkout v2.24.2-wormchaind

# build wormchain
cd wormchain
make build/wormchaind

Get a Recent Wormchain Snapshot

Please ask the Wormhole contributors for a recent Wormchain snapshot to use.

You can also use daily snapshots exported by various teams:

Download and Clean Snapshot

After you download the snapshot, you'll need to clear the wasm cache:

# before starting your node
rm -r /data/wasm/cache

Now you should be able to successfully start your node!

Troubleshooting

We were just able to successfully statesync when retaining the wasm folder and deleting the wasm cache, just fyi:

  • you need the wasm folder from a synced node
  • then configure statesync + unsafe-reset-all
  • then copy in wasm state cp -r <your-wasm-folder-location> $DAEMON_HOME/data
  • delete wasm cache rm -r $DAEMON_HOME/data/wasm/cache
  • then start the node & statesync
