Author: StakeWise

Defines the functionality for checking signatures of oracles for validators consolidations

State Variables

uint256 private constant _signatureLength = 65;

bytes32 private constant _consolidationsCheckerTypeHash =
    keccak256("ConsolidationsChecker(address vault,bytes validators)");

IKeeper private immutable _keeper;

Constructor

constructor(address keeper) EIP712("ConsolidationsChecker", "1");

Parameters

Name	Type	Description
`keeper`	`address`	The address of the Keeper contract

Verifies the signatures of oracles for validators consolidations. Reverts if the signatures are invalid.

function verifySignatures(address vault, bytes calldata validators, bytes calldata signatures) external view override;

Parameters

Name	Type	Description
`vault`	`address`	The address of the vault
`validators`	`bytes`	The concatenation of the validators' data
`signatures`	`bytes`	The concatenation of the oracles' signatures

Function for checking signatures of oracles for validators consolidations

function isValidSignatures(address vault, bytes calldata validators, bytes calldata signatures)
    public
    view
    override
    returns (bool);

Parameters

Name	Type	Description
`vault`	`address`	The address of the vault
`validators`	`bytes`	The concatenation of the validators' data
`signatures`	`bytes`	The concatenation of the oracles' signatures

Returns

Name	Type	Description
`<none>`	`bool`	`true` if the signatures are valid, `false` otherwise

Internal function for verifying oracles' signatures

function _isValidSignatures(uint256 requiredSignatures, bytes32 message, bytes calldata signatures)
    private
    view
    returns (bool);

Parameters

Name	Type	Description
`requiredSignatures`	`uint256`	The number of signatures required for the verification to pass
`message`	`bytes32`	The message that was signed
`signatures`	`bytes`	The concatenation of the oracles' signatures

Returns

Name	Type	Description
`<none>`	`bool`	True if the signatures are valid, otherwise false
