Learn how Islamic Coin staking rewards are calculated. ISLMSRB is the governance-set HAQQ reward coefficient net of community tax: bonded ISLM × reward coefficient is minted per year and distributed t

ISLMSRB is a benchmark representing the mean, annualized staking rate across all active Islamic Coin validators.

ISLMSRB is calculated and published by Staking Rewards via the Islamic Coin Profile and Data API.

TL;DR: HAQQ's coinomics module mints bonded ISLM × reward coefficient per year, and the community tax is deducted before distribution. Divided by bonded ISLM, the rate is simply the reward coefficient net of community tax: ISLMSRB = rc/100 × (1 − ct) (3.0% × 0.9 = 2.70% as of September 2026). Validator-level rates factor in performance and commission as in ATOMSRB.

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

ISLM Staking Rewards Rate: ISLMSRB

$$ISLMSRB = rc /100 *(1-ct)$$

Formula Key	Metric Name	Description
rc	Reward Coefficient	Governance parameter of the HAQQ coinomics module: the annual mint as a percentage of total bonded ISLM. 3.0 since governance proposal 42 (passed 12 November 2024).
ct	Community Tax	Community Tax is the percentage of inflation rewards and fees that are sent to the community pool at each block.

ISLM Validator Staking Rewards Rate: ISLMSRB(v)

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

$$ISLMSRB(v) = ATOMSRB(v)$$

ISLM Real Reward Rate: ISLMSRB^R

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

$$ISLMSRB^R = ATOMSRB^R$$

Inflation Rate Behavior

• New ISLM is minted by the HAQQ coinomics module at the end of every block: mint = totalBonded × rc/100 × (blockTime − previousBlockTime) / year. The annual mint is therefore bonded ISLM × Reward Coefficient.

• The Reward Coefficient is a governance parameter. It was initially set to 7.78% and was reduced to 3.0% by governance proposal 42 (passed 12 November 2024). With a 10% community tax, this yields 3.0% × (1 − 0.10) = 2.70% on bonded ISLM.

• Minting is proportional to wall-clock time, not block count, so slower block production does not lower the annualized rate: a longer block mints proportionally more.

• The mint is sent to the fee collector and distributed through the standard Cosmos SDK distribution module, where the community tax is deducted.

• The HAQQ documentation specifies a maximum supply of 100 billion ISLM, after which minting stops. On-chain supply (about 18.2 billion ISLM in September 2026) is far below this cap.

• The voluntary Burn & Mint programme (burning ISLM to mint the separate HAQQ token) reduces ISLM supply but does not change the minting formula or ISLMSRB.

• The inflation rate published by Staking Rewards is the annual mint (bonded ISLM × Reward Coefficient) relative to circulating supply.

Other Islamic Coin 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 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.
