The first native Cross-Subnet message was sent on Avalanche Mainnet using Avalanche Warp Messaging (AWM) on December 22nd, 2022. Following this milestone, ACP-30 proposed activating AWM on the C-Chain and Subnet-EVM. Activating this ACP brings native cross-chain communication to every EVM Chain in the Avalanche Ecosystem and establishes a standard for future VMs to communicate using AWM.

With AWM, there are no third-party intermediaries or trust assumptions outside of the validator set of the Primary Network and the communicating Subnets. With only the validators of a Subnet, every Avalanche Subnet can send messages to one another. AWM leverages the Avalanche P-Chain as a registry of all Subnets’ validator sets including a BLS Public Key for each validator.
