validateState
Check that linear-curve coefficients form a legal v1 engine.
Returns true when floor, slope, ramp, and continuity constraints hold. Snapshots loaded by the SDK are already revision-gated with assertMathRevision. Call this when you built an engine yourself (tests, charts of launchPreset()).
Import
import { validateState } from "@repo/contract-client/math";Usage
import { launchPreset, validateState } from "@repo/contract-client/math";
validateState(launchPreset());
validateState(snapshot.engine);Checks include: schemaVersion === 1, positive floor and main slope, ramp scalar > 1 WAD, rampWidth ≤ rampEnd, piecewise continuity at x2, and positive price samples.
Return Value
boolean — true if the state is legal. Does not throw on an illegal state.
Parameters
state
- Type:
{ schemaVersion, floorPriceWad, rampEndSupplyWad, rampWidthWad, rampScalarWad, mainSlopeWad }
The decoded engine. LinearCurveState (branded bigints) is accepted.
validateState(snapshot.engine);Error
None. Price helpers throw InvalidAmountError if they still run against a bad state.
