Increase A Validator's $BERA Stake

The following steps will guide you through the process of increasing a Validator's $BERA stake to increase their stake weight and increase the probability of proposing blocks.

This guide assumes that a Validator is already in the Active Set.

If you would like to test this out locally, consult our guide to a local Kurtosis-based devnet, which includes instructions on testing deposits.

Active Set & $BERA Stake

Currently, the Active Set consists of 69 Validators, which is the number of Validators that can propose blocks.

The Active Set is determined by the amount of $BERA staked, where the top stakers are included in the Active Set. To be included in the Active Set, a Validator must stake at least $BERA or 1 $BERA more than the lowest staker in the Active Set (whichever is greater).

If a Validator is removed from the Active Set, all $BERA staked to that Validator will be returned to the Validator's Withdrawal Credentials Address.

Staking Considerations

There are a few points to consider with staking:

• Stake Returned To Single Address - All $BERA staked to a Validator is returned to the Validator's Withdrawal Credentials Address. If there are multiple stakers, an agreement must be put in place with the Validator to ensure that the $BERA is returned to the correct addresses.
• Liquid Staking Protocols - Managing multiple stakers with a single Validator can be difficult. As an alternative, Liquid Staking Protocols are an option.

Requirements

Before you begin, ensure you have the following:

• A Validator that is already in the Active Set
• A Validator's pubkey - PubKeys can be found at Berachain Hub Validators
• A minimum of $BERA or 1 $BERA more than the lowest staker in the Active Set (whichever is greater)
• Foundry
