Whitelist

Core whitelist module logic, including Merkle proof verification.

Functions

_checkWhitelist

Verifies if an address is whitelisted for a specific amount using a Merkle proof.

Internal function to be used by vault on fractionalised token minting. If whitelisting is disabled, this function reverts.

function _checkWhitelist(bytes32[] calldata _proof, address _account, uint256 _amount) internal view returns (bool);

Parameters

Name	Type	Description
_proof	bytes32[]	The Merkle proof.
_account	address	The address to verify.
_amount	uint256	The amount associated with the address.

Returns

Name	Type	Description
<none>	bool	True if proof is valid or if whitelisting is disabled. False otherwise.

_computeLeaf

Helper function to compute the keccak256 hash of the packed address and amount.

Used to generate leaf nodes for the Merkle tree.

Hashes of the leafs are generated using keccak256(bytes.concat(keccak256(abi.encode(...)))), which is the same as OpenZeppelin/merkle-tree package.

function _computeLeaf(address _account, uint256 _amount) internal view returns (bytes32);

Parameters

Name	Type	Description
_account	address	The address to hash.
_amount	uint256	The amount associated with the address.

Returns

Name	Type	Description
<none>	bytes32	The keccak256 hash.
