# Metis SRB

METISSRB is a benchmark representing the mean, annualized staking rate across all active Metis validators.

METISSRB is calculated and published by Staking Rewards via the [Metis Profile](https://www.stakingrewards.com/asset/metis-token) and [Data API](https://www.stakingrewards.com/data-api).

> **TL;DR:** Metis staking rewards are calculated from the amount of rewards accrued over a 7-day period, divided by the 7-day average of sequencer staked tokens, then annualized by multiplying by 52 weeks.

### METIS Staking Rewards Rate: METISSRB

$$
METISSRB = trd / ast\*t\_w
$$

<table><thead><tr><th width="149">Formula key</th><th width="157">Metric name</th><th>Description</th></tr></thead><tbody><tr><td>trd</td><td>Total Rewards Difference</td><td>The amount of rewards accrued over the 7-day period.</td></tr><tr><td>ast</td><td>Average Staked Tokens</td><td>The 7-day average of sequencer's staked tokens.</td></tr><tr><td><span class="math">t_w</span></td><td>Week Constant</td><td>52w</td></tr></tbody></table>

#### Slashing

* METISSRB does not factor in the possibility of slashing occurrences.
* It's important to note that if validator entities face slashing, rewards will increase, as the slashed tokens are reallocated among validators.

***

### METIS Validator Staking Reward Rate: METISSRB(v)

Token holders cannot delegate assets directly to sequencers, therefore sequencers don't distribute rewards by design. Unless the sequencer is a liquid staking provider.

$$
METISSRB(v) = METISSRB
$$

***

#### Observation Period:

* The METISSRB is determined based on the latest generated block at the point of evaluation.
* This data is then annualized for a comprehensive year-long projection.

#### Calculation

The calculation happens every 1o minutes and is immediately published via [Data API](https://www.stakingrewards.com/data-api).

#### Limitations

* METISSRB excludes rewards accrued from on-chain fees.
* METISSRB employs a 365-day convention for annualizing current slot times. This convention remains consistent and does not accommodate adjustments for leap years.

***

### METIS Real Reward Rate: METISSRB^R

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

$$
METISSRB^R=1 + METISSRB/(1+ir) -1
$$

<table><thead><tr><th width="140">Formula key</th><th width="144">Metric name</th><th>Description</th></tr></thead><tbody><tr><td>ir</td><td>Inflation Rate</td><td>The annual provisions divided by the circulating supply.</td></tr></tbody></table>

**Inflation Rate Behavior**

* Metis inflation is influenced by Sequencer Mining, which allocates 3M METIS from the Ecosystem Development Fund to staking rewards. The Mining Rewards Rate is set at 20% for the first 12 months to incentivize participation in network security.
