1/ We’re thrilled to announce that STRK Staking v2 is going live on Mainnet on June 17!
This upgrade brings two key features for validators:
> Block Attestation: Validators will now need to attest to randomly selected blocks during each epoch, proving they’re actively tracking the network and reliable.
> Commission Adjustments: Validators will be able to raise their commission, but only under strict conditions designed to protect delegators.
More details on both features in the next tweets.
To enable this upgrade on Mainnet, the staking contracts will be paused for a few hours, allowing the migration from v1 to v2 and giving validators time to integrate.
As a delegator, there’s nothing you need to do for this migration. But once v2 is live on June 17, validator liveness metrics will become visible, a key factor for your rewards. Keep an eye on it and re-delegate if necessary.
See you next week for the migration 🫵

2/ Block Attestation
Starknet will now run in epochs, and validators must attest to randomly selected blocks during each one.
Only active validators will receive staking rewards, if you're not monitoring the network, you're leaving rewards on the table. And when a validator fails to attest, their delegators lose out too.
This upgrade ensures validators are alive, responsive, and ready for future consensus duties (coming EOY). It also gives delegators visibility into validator performance.
And yes, as a delegator, you can switch validators anytime, no need to wait 21 days.
