Title: InfraredBERAWithdraworLite

This contract is only responsible for handling involuntary exits from the CL. It is a light version of the InfraredBERAWithdrawor contract.

This contract should be upgraded once withdrawals are enabled by https://github.com/berachain/beacon-kit.

expects compliance of https://github.com/ethereum/EIPs/blob/master/EIPS/eip-7002.md

State Variables

WITHDRAW_REQUEST_TYPE

The withdrawal request type, execution layer withdrawal.

uint8 public constant WITHDRAW_REQUEST_TYPE = 0x01

WITHDRAW_PRECOMPILE

The address of the Withdraw Precompile settable in the next upgrade.

address public WITHDRAW_PRECOMPILE

InfraredBERA

The address of the InfraredBERA.sol contract.

address public InfraredBERA

claimor

The address of the InfraredBERAClaimor.sol contract.

This contract will be set in the next upgrade.

address public claimor

requests

Outstanding requests for claims on previously burnt ibera The key = nonce associated with the claim

mapping(uint256 => Request) public requests

fees

Amount of BERA internally set aside for withdraw precompile request fees

uint256 public fees

rebalancing

Amount of BERA internally rebalancing amongst Infrared validators

uint256 public rebalancing

nonceRequest

The next nonce to issue withdraw request for

uint256 public nonceRequest

nonceSubmit

The next nonce to submit withdraw request for

uint256 public nonceSubmit

nonceProcess

The next nonce in queue to process claims for

uint256 public nonceProcess

__gap

Reserve storage slots for future upgrades for safety

uint256[40] private __gap

Functions

initialize

Initialize the contract (replaces the constructor)

function initialize(address _gov, address _keeper, address ibera)
    public
    initializer;

Parameters

_enoughtime

Checks whether enough time has passed beyond min delay

function _enoughtime(uint96 then, uint96 current)
    private
    pure
    returns (bool has);

Parameters

Returns

reserves

Amount of BERA internally set aside to process withdraw compile requests from funds received on successful requests

function reserves() public view returns (uint256);

queue

Queues a withdraw from InfraredBERA for chain withdraw precompile escrowing minimum fees for request to withdraw precompile

not used until next upgrade.

function queue(address, uint256) external payable returns (uint256);

execute

Executes a withdraw request to withdraw precompile

not used until next upgrade.

function execute(bytes calldata, uint256) external payable;

process

Processes the funds received from withdraw precompile to next-to-process request receiver

Reverts if balance has not increased by full amount of request for next-to-process request nonce

not used until next upgrade.

function process() external pure;

sweep

Handles Forced withdrawals from the CL.

RESTRICTED USAGE: This function should ONLY be called when:

• A validator has been forced to exit from the CL.

The funds will enter the IBERA system as a deposit via the InfraredBERADepositor.

function sweep(bytes calldata pubkey) external onlyGovernor;

Parameters

sweepUnaccountedForFunds

Handles excess stake that was refunded from a validator due to non-IBERA deposits exceeding MAX_EFFECTIVE_BALANCE

RESTRICTED USAGE: This function should ONLY be called when:

• A non-IBERA entity deposits to our validator, pushing total stake above MAX_EFFECTIVE_BALANCE
• The excess stake is refunded by the CL to this contract

The funds will enter the IBERA system as yield via the FeeReceivor

This should NEVER be used for:

• Validators exited due to falling out of the validator set

Note: access: Only callable by governance

function sweepUnaccountedForFunds(uint256 amount) external onlyGovernor;

Parameters

receive

receive() external payable;

Structs

Request

The request struct for withdrawal requests.

struct Request {
    address receiver;
    uint96 timestamp;
    uint256 fee;
    uint256 amountSubmit;
    uint256 amountProcess;
}
