Avalanche Warp Navigator

[Nuttymoon]

Dependencies

• feat(jsonrpc): add error field to info structs ava-labs/avalanche-rs#34

Changes

Avalanche Warp Navigator:

• Add autogenerated WarpMessenger contract bindings (from ABI)
• Add structs to decode Avalanche Warp messages. A WarpMessage is composed of:
  • A WarpUnsignedMessage: see UnsignedMessage
  • A VerifiedWarpMessage: pre-verified Warp message as it will be parsed on the destination chain
  • A status: Sent or Signed(u16) with the number of signatures
  • A list of WarpMessageNodeSignature
• The payload of a WarpUnsignedMessage put further be decoded to an AddressedPayload (see AddressedPayload), which is specific to sending Warp messages between Subnet-EVM chains
• Add avalanche warp navigate command in the CLI

Additional comments

• Only Subnet-EVM chains are supported atm since each VM type will have its mechanism to retrieve messages (event logs of the WarpMessenger precompile in this case)
• Warp message decoding rarely fails and is done in a "best effort" way, further decoding parts of the message if possible
• I did not implement all tests for this feature since it's pretty complicated to spin up a Warp-enabled chain with ANR at the moment
• The mechanism for retrieving node signatures of messages is not optimal but I couldn't do better for the moment. See Cannot aggregate Warp message signatures with warp_getAggregateSignature ava-labs/subnet-evm#806
• We could probably move some structs to avalanche-types-rs after a discussion with Ava Labs
