# Cronos SRB

Learn how Cronos staking rewards are calculated. CROSRB uses the Cosmos SDK formula with annual provisions, fees, community tax, and bonded CRO tokens.

CROSRB is a benchmark representing the mean, annualized staking rate across all active Cronos validators.

CROSRB is calculated and published by Staking Rewards via the [Cronos Profile](https://www.stakingrewards.com/asset/crypto-com-coin) and [Data API](https://www.stakingrewards.com/data-api).

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

{% hint style="info" %}
The calculations are derived from the ATOMSRB documentation, serving as the foundational reference to ensure the accuracy of relevant metrics.

### CRO Validator Staking Rewards Rate: CROSRB(v)

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

### CRO Real Reward Rate: CROSRB^R

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

$$
CROSRB^R = ATOMSRB^R

#### Inflation Rate Behavior (Cronos POS)

{% hint style="warning" %}
Cronos POS does not use the Cosmos Hub bonded-ratio inflation curve described in the ATOMSRB section above. The rules below replace it for CRO; the inflation-rate formula (annual provisions adjusted by actual block time, divided by total supply) is unchanged.
{% endhint %}

* The base inflation rate is fixed at 1% (`inflation_min` = `inflation_max` = 1%, `inflation_rate_change` = 0), so it does not respond to the bonded ratio.
* Since the V7 upgrade, the `x/inflation` module decays that base rate continuously by `decay_rate` = 6.8% per month, where a month is `blocks_per_year / 12` blocks: `inflation = 1% × (1 − 0.068)^(blocks since decay start / 525,960)`. Annual provisions therefore fall by roughly 6.8% each month.
* As of 10/09/2026 the chain's nominal inflation is about 0.72% and annual provisions are about 715M CRO.
* Total supply, net of burned addresses, is capped at 100B CRO (`max_supply`). At the current decay schedule, cumulative future emission stays below this cap.

#### Base Rewards Floor

* The `x/tieredrewards` module sets a staker reward floor of `target_base_rewards_rate` = 3% of bonded CRO per year. In each block, if emission after community tax pays stakers less than this target, the shortfall is topped up from the module's RewardsPool and distributed to bonded validators pro rata.
* The top-up is a transfer from an existing pool, not new issuance, so it does not change the inflation rate.
* As of 10/09/2026 the floor is not active: emission pays stakers about 40% more than the floor target. On the current decay schedule it becomes active around March 2027. Once active, the floor holds only while the RewardsPool is funded.
* CROSRB currently reflects emission only. Once the floor becomes active, CROSRB is planned to be calculated as the greater of the emission-based rate and the floor.

***

#### Limitations

* CROSRB excludes the optional tier bonuses of the `x/tieredrewards` module (+2%, +4% and +7% annual bonus for 1-, 2- and 4-year locks). These are opt-in lock products funded from the RewardsPool, not base staking rewards.

### Other Cronos metrics calculated by Staking Rewards

<table><thead><tr><th width="188">Metric</th><th>Description</th></tr></thead><tbody><tr><td>Delegated Tokens</td><td>The number of tokens delegated to validators.</td></tr><tr><td>Self Staked Tokens</td><td>The number of tokens staked by validators directly.</td></tr><tr><td>Staking Wallets</td><td>This metric refers to the number of unique delegator addresses with at least one delegation on-chain. An address delegating to several validators is counted once. It excludes considerations of any minimum delegation thresholds.</td></tr></tbody></table>
