PendleOracle

PendleOracle prices a dated Pendle principal token from either a PT-to-asset or PT-to-SY TWAP and the configured underlying USD price. Deployment artifacts contain at least two incompatible generations.

V1 proxy generation

constructor(
    address market,
    address ptOracle,
    uint8 rateKind,
    address ptToken,
    address underlyingToken,
    address resilientOracle,
    uint32 twapDuration
)

rateKind selects PT_TO_ASSET or PT_TO_SY. BNB Chain proxy 0xEa7a92D12196A325C76ED26DBd36629d7EC46459 pointed to V1 implementation 0x8A183a0d35290D849e8915710D3aEE7e463705E7 at block 118367342.

V2 capped generation

The PendleOracle v2.16.0 source takes one 13-field structure:

struct ConstructorParams {
    address market;
    address ptOracle;
    RateKind rateKind;
    address ptToken;
    address underlyingToken;
    address resilientOracle;
    uint32 twapDuration;
    uint256 annualGrowthRate;
    uint256 snapshotInterval;
    uint256 initialSnapshotMaxExchangeRate;
    uint256 initialSnapshotTimestamp;
    address accessControlManager;
    uint256 snapshotGap;
}

It also exposes immutable MARKET, PT_ORACLE, RATE_KIND, TWAP_DURATION, and UNDERLYING_DECIMALS, plus the common V2 cap API. Construction verifies that the Pendle oracle has sufficient observation history for the requested duration.

BNB Chain PendleOracle-PT-USDe-30OCT2025 at 0xAa5138e86c078fd2859a929173B3870b5003EC30 is a non-proxy V2 example with code present at block 118367342.

A maturity date in an artifact name is not enough to delete its reference. Before labeling an instance historical, verify the current ResilientOracle token config, consuming market balances and debt, and any remaining exit or recovery duty.
