Avalanche Warp Messaging

Avalanche Warp Messaging (AWM) was developed to make all Avalanche blockchains natively interoperable. Ideally, this solution would introduce as few trust assumptions as possible, meaning the blockchains would not depend on a third-party or intermediary that could risk centralization or single-point failures.

AWM allows Avalanche L1s to communicate with one another via authenticated messages by providing signing and verification primitives in AvalancheGo. These are used by the blockchain VMs to sign outgoing messages and verify incoming messages. Any Virtual Machine (VM) on Avalanche can integrate AWM to send and receive messages across Avalanche Avalanche L1s.

Therefore, AWM is not EVM specific, but rather a general cross-Avalanche L1 communication protocol.
