AvalancheGo Banff 5 ([email protected]) Release
AvalancheGo Banff 5 is now live, featuring Avalanche Warp Messaging (AWM), which allows developers to utilize high-performance, interoperable blockchain networks out-of-the-box.
Introduction to Avalanche Warp Messaging (AWM)
Avalanche is closing out the year strong with the final AvalancheGo release of 2022. Avalanche Warp Messaging (AWM) is rolling out in AvalancheGo Banff 5, bringing fast, reliable native communications to all Avalanche Subnets. AWM is available today in both the Golang and Rust VM SDKs for use by any VM builder. Soon, this capability will be rolled out to the subnet-evm, giving Subnet creators native, cross-chain communication capabilities out-of-the-box.
Enhancing Subnets with Native Communication
Prior to the release of Banff 5, Subnets were already a leading solution to help scale custom blockchain networks. Subnets gave anyone the power of Avalanche along with fully customizable parameters and rulesets that catered to the unique needs of every deployment. No longer do permissionless dApps have to compete with others for infrastructure resources, and no longer do large enterprise deployments have to worry about compliance, as they can be programmed in a permissioned environment.
Introducing Avalanche Warp Messaging (AWM)
The next major advancement for Subnets was native communication. Projects that wanted to transfer assets or data between Subnets had to deploy and manage their own bridges. This all ends today with the launch of Avalanche Warp Messaging (AWM) in Banff 5. Subnets will never be the same.
Technical Details of Avalanche Warp Messaging (AWM)
AWM enables Subnet Validators to collectively produce a BLS Multi-Signature that attests to the validity of an arbitrary message (e.g., transfer, contract data, etc.) that can be verified by any other Subnet. Because all Subnet Validators must validate the Primary Network via the P-Chain, they can access the stake weights and registered BLS public keys of any other Subnet at any time. This means that Subnets communicating with each other don’t need to periodically send each other information about changes in their respective validator sets to continue verifying messages, making any-to-any messaging practical. Elastic Subnets, AWM, and arbitrary VM support via both Golang and Rust Developer SDKs make Subnets the most performant and complete solution for launching your own blockchain.
Testimonials on Avalanche Warp Messaging (AWM)
“Cross-chain messaging has become a critical tool in our development toolbox enabling Kingdom Studios to build innovative on-chain experiences for the DeFi Kingdoms player base. The Avalanche Warp Messaging gives yet another reason to build in the Avalanche ecosystem, enabling secure transmission of messages between Avalanche Subnets with developer-friendly tooling. AWM allows DeFi Kingdoms to easily interact with DeFi and gaming protocols built on other Avalanche Subnets.” — Magnus Ironroot, Lead Solidity Developer at Kingdom Studios
“The scaling that Subnets introduce is incredibly powerful but their lack of horizontal composability makes the Cross-Subnet UX much harder for users to manage. The native and generic messaging provided by Avalanche Warp Messaging helps move this forward tremendously by enabling direct communication between different blockchains on Avalanche. LayerZero is super excited to build on this new primitive and collaborate on VM SDKs to make Cross-Subnet communication even easier to use.” — Bryan Pellegrino, Co-Founder & CEO at LayerZero Labs
The First Native Subnet-to-Subnet Message on Avalanche
To showcase Avalanche Warp Messaging, Ava Labs developed the XSVM with 2 basic capabilities: transferring assets on a Subnet and transferring assets between Subnets. Ava Labs deployed this VM to the “let there” and “be messaging” Subnets on Avalanche Mainnet.

Future of Avalanche Warp Messaging (AWM)
AWM is supported in the Golang and Rust VM SDKs and can be used by any VM builder today. Over the coming weeks, we will expand support to the subnet-evm. Subnets have improved and grown with more features in the last few months and are rapidly becoming the best place for building the most expressive, performant, and crypto-native platforms. Subnet builders can now utilize Elastic Staking (to allow people to stake custom tokens to validate their subnet), the Rust VM SDK (building blockchains entirely in Rust), and now, Avalanche Warp Messaging (to send messages between Subnets). See you in 2023!
