WBETHOracle

WBETHOracle obtains BETH per WBETH from WBETH.exchangeRate(), then uses the configured ETH price from the ResilientOracle. It inherits the capped V2 base.

constructor(
    address wbeth,
    address eth,
    address resilientOracle,
    uint256 annualGrowthRate,
    uint256 snapshotInterval,
    uint256 initialSnapshotMaxExchangeRate,
    uint256 initialSnapshotTimestamp,
    address accessControlManager,
    uint256 snapshotGap
)

The BNB mainnet v2.16.0 artifact is the non-proxy contract 0x49938fc72262c126eb5D4BdF6430C55189AEB2BA. At block 118367342, its snapshot interval was 2,592,000 seconds, its growth rate was 1,471,334,348 per second, its gap was 4,215,128,607,557,400, and isCapped() returned false.

BNB testnet deployment artifacts include an older proxy shape. Select ABI by address and environment rather than applying this mainnet V2 constructor globally.
