☄️Andromeda SRB

Learn how Andromeda staking rewards are calculated. ANDRSRB uses the Cosmos SDK formula with annual provisions, fees, community tax, and staked ANDR tokens.

ANDRSRB is a benchmark representing the mean, annualized staking rate across all active Andromeda validators.

ANDRSRB is calculated and published by Staking Rewards via the Andromeda Profile and Data API.

TL;DR: Andromeda staking rewards follow the Cosmos SDK formula (ATOMSRB): annual provisions plus annualized fees, minus community tax, divided by total staked ANDR tokens. Andromeda mints nothing: its annual provisions are a drip of 2.5 ANDR per block from a finite, governance-funded rewards_dripper account. The drip counts only while that account holds at least one block's worth; when it is empty, annual provisions are 0. Validator-level rates factor in performance and commission.

The calculations are derived from the ATOMSRB documentation, serving as the foundational reference to ensure the accuracy of relevant metrics.

ANDR Staking Rewards Rate: ANDRSRB

$$ANDRSRB = \frac{(ap + df \cdot 365) \cdot (1 - ct)}{st}$$

The formula has the same shape as ATOMSRB. The difference is where annual provisions ($ap$) come from:

$$ap = \begin{cases} rpb \cdot bpy & \text{if } b_{rd} \geq rpb \\ 0 & \text{otherwise} \end{cases}$$

Formula Key	Metric Name	Description
$ap$	Annual Provisions	ANDR paid to stakers per year from the rewards drip
$rpb$	Rewards Per Block	Governance-set drip per block (rewards_per_block in Andromeda's distribution module, currently 2.5 ANDR)
$bpy$	Blocks Per Year	Observed blocks per year, from the chain's actual block time, not the static mint parameter
$b_{rd}$	Rewards Dripper Balance	Current balance of the rewards_dripper module account
$df$	Daily Fees	Average daily transaction fees over the last 30 days
$ct$	Community Tax	Share of rewards sent to the community pool (community_tax, currently 2%)
$st$	Staked Tokens	ANDR bonded to active validators

• Andromeda's mint module is disabled: its annual provisions and inflation parameters are all 0. Staking rewards are instead paid from the rewards_dripper module account, which governance funds from the community pool (for example proposal 12). Each block, that account sends rewards_per_block to the distribution module.

• The account is finite. Once it holds less than one block's drip, distribution stops until governance refills it. Reading rewards_per_block alone would overstate rewards, because the parameter keeps its value after the account is empty. ANDRSRB therefore gates annual provisions on the live account balance, and provisions resume on their own after a refill.

• The rewards_dripper account ran empty at block 14,999,251 (2026-09-10). Since then annual provisions are 0 and ANDRSRB reflects fees only.

• Andromeda's distribution module is a fork of Cosmos x/distribution registered under the andromeda.distribution.v1beta1 namespace. Both rewards_per_block and community_tax are read from it.

• Non-compounded, and includes both claimed and unclaimed rewards.

ANDR Validator Staking Rewards Rate: ANDRSRB(v)

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

$$ANDRSRB(v) = ATOMSRB(v)$$

ANDR Real Reward Rate: ANDRSRB^R

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

$$ANDRSRB^R = \frac{1 + ANDRSRB}{1 + ir} - 1$$

Where $ir$ = Inflation Rate.

Inflation Rate Behavior

Andromeda is non-inflationary, so the inflation rate is 0.

• The mint module issues nothing: inflation, inflation_min, inflation_max and annual_provisions are all 0.

• The rewards drip moves tokens that already exist, out of a pre-funded account, so it is not issuance.

• On-chain supply is falling.

With $ir = 0$, the real reward rate equals the reward rate: $ANDRSRB^R = ANDRSRB$.

Other Andromeda metrics calculated by Staking Rewards

Metric	Description
Fee Revenue	The Fee Revenue reflects the annualized transaction fees, derived from the fees accumulated within the last 24 hours, evaluated at the prevailing USD rate.
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 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.
