Methodology

The annualized yield earned by miners who hold unclaimed SLVR mining rewards in the Miner State Vault. Funded by the refining fee when miners cash out — currently 20% on fresh rewards, decaying to 10% over 24 hours — and redistributed to remaining unclaimed holders.

APR = ( minerIndex(t) − minerIndex(t − W) ) / 1e18 × ( 31,536,000 / W )

W = 86,400 seconds (trailing 24 hours)

Annualization: Δindex / 1e18 × 365

minerIndex

Global cumulative refining fee per 1 unclaimed SLVR, WAD-scaled (1e18 = 1.0). Selector: 0x9806b4d2

W

86,400s — a trailing 24-hour window. A new accumulator is withheld as "early" until the first full window exists.

31,536,000

Seconds per year (365 days). Annualization constant.

A 24-hour window responds quickly to refining activity and can remain volatile, especially when the unclaimed pool is small. The formula is mechanically exact for a continuously unclaimed position, but the annualized rate is not a promise of future returns.

The original and gas-optimized lotteries each kept their own miner state. At round 33,500, miner state moved to a separate, permanent vault. All three minerIndex accumulators are independent; an APR window must never cross a reset.

Index values are read directly at both window boundary blocks through archive-capable Robinhood Chain RPCs. The vault contract is independently verifiable on the Blockscout explorer.

tokenIds     = every ve lock ever minted   (ERC-721 Transfer from 0x0)
for each id: (amount, lockStart, lockEnd, permanent, …) = locks(id)
total_staked = Σ amount   where amount > 0            (active locks only)
permanent    = Σ amount   where permanent OR lockEnd = 0
timelocked   = total_staked − permanent

Reading current on-chain state (rather than replaying events) means withdrawals and permanent-conversions are handled for free. Permanent locks burn the underlying SLVR, so their amount also appears in the “emitted” figure below.

circulating    = totalSupply() − balanceOf(teamVesting) − balanceOf(growthFund)
cumulativeBurned = Σ value of Transfer(to = 0x0) on the SLVR token
emitted        = totalSupply() + cumulativeBurned      (total ever minted)
emitted_pct    = emitted / 500,000                     (progress toward cap)
max_supply     = 500,000 SLVR (hard cap)

The vitals “% mined / 500K” progress bar uses emitted_pct, not totalSupply / cap.

emitted(t)     = totalSupply(t) + cumulativeBurned(t)
remaining      = 500,000 − emitted(now)
window         = [ max(genesis, now − 30d), now ]
grossEmitted   = emitted(now) − emitted(window_start)   (SLVR minted in window)
perDayGross    = grossEmitted / window_days
runway_months  = remaining / perDayGross / 30.44

If perDayGross ≤ 0 the estimate is withheld (insufficient data).
