Moonbeam <-> Moonriver Bridge Support

Commands for running the Moonbeam <-> Moonriver Bridge:

To run the bridge between Moonbeam and Moonriver, you'll need to adapt the example below with your relayer private key.

<relayer_private_key>: A 32-byte hex-encoded key (must be 0x-prefixed and consist of 64 hexadecimal characters).

Alternatively, you can load the private key from a file using the --{target,moonbeam,moonriver}-signer-file <FILE> parameter.
