Avalanche introduced Helicon, a network upgrade already activated on the Fuji Testnet. It combines six Avalanche Community Proposals spanning validator economics and transaction execution on the C-Chain. Mainnet activation timing and the required AvalancheGo version will be confirmed through a separate mainnet pre-release.
The largest validator-facing change is Auto-Renewed Staking. Instead of reaching a fixed end date and manually staking again, an operator can configure a cycle duration and an auto-compound ratio. Rewards are issued automatically by consensus at each cycle boundary, while configuration changes take effect for the following cycle. The design reduces repeated key-signing work and avoids reward gaps caused by leaving and re-entering the validator set.
Helicon also shortens the minimum staking duration, raises the validator uptime requirement and gradually adjusts the minimum consumption rate used in staking economics. ACP-285 is designed to roll out progressively after activation rather than switching the full change on at once.
For the C-Chain, the upgrade introduces Continuous Execution together with a dynamic minimum gas price. Taken together, the six ACPs move Avalanche toward more continuous execution and more flexible validator economics. Operators still need to follow the official AvalancheGo pre-release for final mainnet timing and version requirements.
