Protocol parameters

This page separates constructor defaults from mainnet values read on 2026-07-23. Owner-mutable values can change later. Values are 1e18 fixed-point unless noted. Source of truth: contracts/BrilaDATRebaser.sol.

Rebase policy

Parameter	Constructor default	Live mainnet	Cap / constraint	Meaning
targetRate	1e18	1e18	> 0; immutable in USD mode (= $1.00/DAT, F20)	The peg target.
deviationThreshold	5e16 (5%)	5e16 (5%)	<= 5e17 (50%)	No supply change when deviation is strictly below this; exactly 5% is actionable.
rebaseLag	10	10	> 0	Off-peg % is divided by this per rebase (damping).
rebaseMintPerc	1e17 (10%)	1e17 (10%)	<= 1e18	Share of a positive rebase minted toward the treasury.
maxSlippageFactor	9e17 (90%)	9e17 (90%)	(0, 1e18]	Share of the positive-rebase mint budget sold; existing treasury DAT funds it first.
minRebaseTimeIntervalSec	12h	43200 (12h)	window must fit interval	Minimum spacing between rebases.
rebaseWindowOffsetSec	28800 (08:00 UTC)	28800 (08:00 UTC)	< minInterval	Start of the twice-daily rebase window (08:00 and 20:00 UTC at the 12h interval).
rebaseWindowLengthSec	1h	3600 (1h)	(0, minInterval]	Length of the rebase window.
rebaseDelay (TWAP warmup)	12h	3600 (1h)	unbounded	Delay after init_twap before activate_rebasing.

Oracles

Parameter	Constructor default	Live mainnet	Cap / constraint	Meaning
usdPegMode	constructor	true	immutable	True iff a reserve/USD oracle was set at deploy.
reserveUsdOracle	constructor	Perp adapter	USD mode: rotatable via 24h timelock; never unsettable	Primary reserve→USD feed; see addresses.
secondaryReserveUsdOracle	constructor	Spot adapter	USD mode: required, distinct from primary; 24h-timelocked	Independent reserve→USD feed; bracketed every rebase.
maxReserveOracleAge	1h	3600 (1h)	USD mode: [1m, 2h]	Staleness bound for both reserve/USD feeds.
maxCommitRevealOracleDrift	2e16 (2%)	2e16 (2%)	USD mode: [5e15, 1e17] (0.5%–10%)	Max reserve/USD move tolerated between commit and reveal.
secondaryOracleEnabled	false	false	owner toggle; not required to activate	Optional Chainlink bracket on the pool-TWAP leg.
secondaryOracle	0 (set via setSecondaryOracle)	0	—	The TWAP-leg sanity oracle (both modes).
maxOracleDeviation	1e17 (10%)	1e17 (10%)	[5e15, 2e17] (0.5%–20%)	Tolerance for the oracle brackets (TWAP-leg and the USD dual-feed bracket).
maxSecondaryOracleAge	1h	3600 (1h)	[1m, 2h]	Staleness bound for the TWAP-leg oracle.

Constants (not configurable)

Constant	Value	Meaning
MIN_TWAP_WINDOW	1h	_getTWAP() reverts on a shorter sample window.
COMMIT_BLOCKS	25	Min blocks between commitRebase and revealAndRebase.
REVEAL_BLOCKS	50	Reveal may land through commit block + 50; it expires after.
MAX_RATE	10e18	Off-peg percentage cap (1000%).
ORACLE_ROTATION_DELAY	24h	Timelock on reserve/USD feed rotations.

Token constants (DAT)

Constant	Value
BASE (fragment precision / genesis scaling factor)	1e18
INTERNAL_DECIMALS (underlying precision)	1e24
MIN_SCALING_FACTOR	1e15 (0.001×)
maxScalingFactor()	type(uint256).max / initSupply (shrinks as supply grows)
storage gap	uint256[45] __gap

Reward contracts

Parameter	Contract	Constraint / behavior
DURATION	Both pools	Immutable and nonzero.
START_TIME	Both pools	Immutable and nonzero.
initreward	Incentivizer	Starts nonzero, then halves when stake or getReward rolls an ended period forward.
MIN_STAKED_BLOCKS	Distribution pool	Immutable and nonzero; every stake resets the account's claim timer.

BrilaDATIncentivizer is deployed. BrilaDATDistributionPool is present in source but has no recorded deployment, so it has no live parameter values.

Live incentivizer

Parameter	Mainnet value
DURATION	7776000 seconds (90 days)
START_TIME	1781987792 (2026-06-20 20:36:32 UTC)

Oracle adapter and zap constants

Constant	Value	Meaning
HyperCoreOracleAdapter.DECIMALS	8	Decimal precision returned through IPriceOracle.
BrilaDATZap.MIN_RESERVE	1000	Private per-side reserve floor used before zap math.
