🧪ZetaChain SRB

Learn how ZetaChain staking rewards are calculated. ZETASRB uses the Cosmos SDK formula with annual provisions, fees, community tax, and staked ZETA tokens.

ZETASRB is a benchmark representing the mean, annualized staking rate across all active ZetaChain validators.

ZETASRB is calculated and published by Staking Rewards via the ZetaChain Profile and Data API.

TL;DR: ZetaChain staking rewards follow the Cosmos SDK formula (ATOMSRB): annual provisions plus annualized fees, minus community tax, divided by total staked ZETA tokens. Validator-level rates factor in performance and commission.

The calculations are derived from the ATOMSRB documentation, serving as the foundational reference for validator-level and real reward rate metrics.

For more information visit the ATOMSRB docs.

ZetaChain does not use the standard Cosmos SDK mint module. Instead, it uses a custom emissions module that distributes rewards from a fixed emissions pool. Annual provisions are dynamically computed from the on-chain block_reward_amount parameter rather than from mint/annual_provisions. This is a key difference from ATOMSRB.

ZETA Staking Rewards Rate: ZETASRB

$$ZETASRB = (𝑑𝑝∗𝑎𝑝+𝑑𝑓∗𝑡_𝑦)/𝑠𝑡$$

Formula Key	Metric Name	Description
dp	Distribution Proportion	Distribution Proportion is the validator emissions percentage, currently set to 75%. Read from the on-chain validator_emission_percentage parameter in the emissions module.
ap	Annual Provisions	Dynamically computed as block_reward_amount * blocks_per_year, where block_reward_amount is read from the on-chain emissions module params and blocks_per_year is derived from the actual observed block time.
df	Daily Fees	The total number of tokens paid as transaction fees.
st	Staked Tokens	The total number of tokens bonded with active, non-jailed validators.
$t_y$	Year Constant	365d

ZETA Validator Staking Rewards Rate: ZETASRB(v)

Staking Rewards calculates the ZETASRB for each validator based on their individual performance and commission rate.

$$ZETASRB(v) = ATOMSRB(v)$$

ZETA Real Reward Rate: ZETASRB^R

The real reward rate calculates the ZETASRB adjusted for inflation in the network.

$$ZETASRB^R = ATOMSRB^R$$

Inflation Rate Behavior

• ZetaChain rewards are currently funded from a fixed emissions pool established at genesis. The block_reward_amount parameter determines the per-block emission rate, which is set via governance.

• The emissions pool is projected to deplete around September 2026, at which point the protocol plans to transition to a target of ~2.5% yearly inflation based on the current circulating supply.

• Because annual provisions are dynamically computed from the on-chain block_reward_amount, any governance changes to the emission rate are automatically reflected in ZETASRB.

Other ZetaChain metrics calculated by Staking Rewards

Metric	Description
Delegated Tokens	The number of tokens delegated to validators.
Self Staked Tokens	The number of tokens staked by validators directly.
Staking Wallets	This metric refers to the total quantity of distinct delegations made. It doesn't distinguish based on unique delegator addresses and excludes considerations of any minimum delegation thresholds.
