OracleReportSanityChecker

Some vital data for the Lido protocol is collected off-chain and delivered on-chain via Oracle contracts: AccountingOracle, ValidatorsExitBusOracle. Due to the high impact of data provided by the Oracles on the state of the protocol, each Oracle's report passes a set of onchain sanity checks. For the simplicity of the contracts responsible for handling Oracle's reports, all sanity checks were collected in the standalone OracleReportSanityChecker contract.

Besides the validation methods, the OracleReportSanityChecker contract contains a set of tunable limits and restrictions used during the report validation process. To configure the limits values contract provides the lever methods described in the standalone section. Access to lever methods is restricted using the functionality of the AccessControlEnumerable contract and a bunch of granular roles.

Limits List​

OracleReportSanityChecker introduces a new type LimitsList which contains all the limits used by the contract.

struct LimitsList {
    uint256 churnValidatorsPerDayLimit;
    uint256 oneOffCLBalanceDecreaseBPLimit;
    uint256 annualBalanceIncreaseBPLimit;
    uint256 simulatedShareRateDeviationBPLimit;
    uint256 maxValidatorExitRequestsPerReport;
    uint256 maxAccountingExtraDataListItemsCount;
    uint256 maxNodeOperatorsPerExtraDataItemCount;
    uint256 requestTimestampMargin;
    uint256 maxPositiveTokenRebase;
}
  • churnValidatorsPerDayLimit ∈ [0, 65535] — the max possible number of validators that might been reported as appeared or exited during a single day. AccountingOracle reports validators as appeared once them become pending (might be not activated yet). Thus, this limit should be high enough for such cases because Consensus Layer has no intrinsic churn limit for the amount of pending validators (only for activated instead). For Lido it's limited by the max daily deposits via DepositSecurityModule. In contrast, exited are reported according to the Consensus Layer churn limit.
  • oneOffCLBalanceDecreaseBPLimit ∈ [0, 10000] — the max decrease of the total validators' balances on the Consensus Layer since the previous oracle report. Represented in the Basis Points (100% == 10000).
  • annualBalanceIncreaseBPLimit ∈ [0, 10000] — the max annual increase of the total validators' balances on the Consensus Layer since the previous oracle report. Represented in the Basis Points (100% == 10000).
  • simulatedShareRateDeviationBPLimit ∈ [0, 10000] — the max deviation of the provided simulatedShareRate and the actual one within the currently processing oracle report. Represented in the Basis Points (100% == 10000).
  • maxValidatorExitRequestsPerReport ∈ [0, 65535] — the max number of exit requests allowed in report to ValidatorsExitBusOracle
  • maxAccountingExtraDataListItemsCount ∈ [0, 65535] — the max number of data list items reported to accounting oracle in extra data
  • maxNodeOperatorsPerExtraDataItemCount ∈ [0, 65535] — the max number of node operators reported per extra data list item
  • requestTimestampMargin ∈ [0, type(uint64).max] — the min time required to be passed from the creation of the request to be finalized till the time of the oracle report
  • maxPositiveTokenRebase ∈ [1, type(uint64).max] — the max positive token rebase allowed per single oracle report token rebase happens on total supply adjustment, huge positive rebase can incur oracle report sandwiching. Uses 1e9 precision, e.g.: 1e6 — 0.1%; 1e9 — 100%; type(uint64).max — unlimited rebase.

View Methods​

getLidoLocator()​

Returns the address of the protocol-wide LidoLocator instance.

function getLidoLocator() returns (address)

getOracleReportLimits()​

Returns the limits list used for the sanity checks as the LimitsList type.

function getOracleReportLimits() returns (LimitsList memory)

getMaxPositiveTokenRebase()​

Returns max positive token rebase value with 1e9 precision (e.g.: 1e6 — 0.1%; 1e9 — 100%):

note

Special values:

  • 0 (zero value) means uninitialized
  • type(uint64).max means unlimited, e.g. not enforced

Get max positive rebase allowed per single oracle report. Token rebase happens on total supply and/or total shares adjustment, while huge positive rebase can incur oracle report sandwiching stealing part of the stETH holders' rewards.

The relative positive rebase value derived as follows:

stETH balance for the account defined as:

    balanceOf(account) =
        shares[account] * totalPooledEther / totalShares = shares[account] * shareRate

Suppose shareRate changes when oracle reports (see handleOracleReport) which means that token rebase happens:

    preShareRate = preTotalPooledEther() / preTotalShares()
    postShareRate = postTotalPooledEther() / postTotalShares()
    R = (postShareRate - preShareRate) / preShareRate

here R > 0 corresponds to the relative positive rebase value (i.e., instant APR).

function getMaxPositiveTokenRebase() returns (uint256)
