On-chain functions

Developers interact primarily with StakingManager and the FHYPE ERC20.

• Staking

function stake(address validatorChoice) external payable;

Pass address(0) to use the default validator, or an active validator address on first stake.

• Unstaking

function queueWithdrawal(uint256 fHYPEAmount) external;
function confirmWithdrawal(uint256 withdrawalId) external;
function batchConfirmWithdrawals(uint256[] calldata withdrawalIds) external;

Queue, wait for withdrawalDelay, then confirm to receive HYPE. A 0.1% unstake fee (default 10 bps) goes to treasury.

• Exchange rate and conversions

function getExchangeRate() external view returns (uint256);
function HYPEToFHYPE(uint256 hypeAmount) external view returns (uint256);
function fHYPEToHYPE(uint256 fHYPEAmount) external view returns (uint256);

Returns HYPE per fHYPE scaled to 1e18. Conversions don’t include the unstake fee.

• FHYPE token (ERC20)

function balanceOf(address account) external view returns (uint256);
function decimals() external pure returns (uint8); // 18

fHYPE uses 18 decimals and supports standard ERC20 operations.
