The Avalanche (@avax) Foundation has activated the Helicon upgrade on the Fuji Testnet. The upgrade went live on July 28, 2026, at 11:00 AM ET, bringing auto-renewed staking, shorter minimum staking durations, and Continuous Execution to the network.
The upgrade is driven by six Avalanche Community Proposals (ACPs) and is currently in testnet-stage testing rather than live on mainnet, so any staking-economics changes are not yet in effect for $AVAX holders. It builds on the earlier Octane and Granite upgrades.
One of the headline changes is the introduction of Continuous Execution to the Avalanche C-Chain. The C-Chain runs an EVM-compatible smart contract environment, sits alongside the X-Chain for asset issuance and the P-Chain for validator coordination, and is at the heart of most consumer-facing activity on the network.
On the staking side, the upgrade draws on proposals including ACP-236. Continuous staking makes it easier for users to keep their funds staked longer by reducing friction and the number of transactions required, with validators able to stake continuously and accrue rewards once per specified cycle.The current system restricts flexibility by requiring stakers to specify an explicit end time and enforcing minimum and maximum staking durations, limiting their ability to respond to changing market conditions or liquidity needs.
Ava Labs founder Emin Gün Sirer (@el33th4xor) noted that the changes prioritize correctness over convenience, signaling that the team is taking a measured approach before committing to mainnet activation. The Foundation confirmed that mainnet timing will be announced in a future pre-release update.
Avalanche Community Proposals are how protocol upgrades are introduced and discussed within the ecosystem. Rather than implementing changes immediately, proposals are published publicly so validators, developers, researchers, and community members can review them before they are adopted.
The Fuji Testnet serves as Avalanche's primary staging environment before any changes reach production. It is used to safely trial upgrades, smart contracts, and cross-chain features before mainnet deployment.
