Contract Interfaces and ABI

Contract Addresses & ABI

Below is the HyperFlash ABI used to query the on-chain state and make transactions.

hyperflash.abi

The contract has been deployed to the following addresses:

Location	Contract Address
HyperEVM Testnet	--
HyperEVM Mainnet	0x34a70Db6c0E3d5f93d7026fa6dCd6e11adFd56C5

Once our second audit concludes, the contracts will be verified on HyperEVM explorers.

On-chain functions

Developers can interact with HyperFlash at the smart contract level with an ABI. We detail the relevant functions here:

Staking

function stake() public payable;

Use this function to stake HYPE and get back flashHYPE, using msg.value to send HYPE.

Unstaking

function unstake(uint256 flashHYPEAmount) public;

Use this function to unstake HYPE by burning flashHYPE. If the smart contract has enough in reserve, then the HYPE is returned to the user immediately. Otherwise the user enters a queue to unstake. A 0.1% unstaking fee is charged on the HYPE.

Get Exchange Rate

function getExchangeRate() public view returns (uint256);

Returns the current exchange rate between flashHYPE and HYPE. In particular, it is defined the ratio of the totalHYPE owned by the contract divided by the totalFlashHYPE in existence. There are 18 decimals to this quantity.

We provide two other helpers function to disambiguate the conversion:

function getFlashHYPEForHYPE(uint256 hypeAmount) public view returns (uint256);
function getHYPEForFlashHYPE(uint256 flashHYPEAmount) public view returns (uint256);

This allows for a simple conversion between the two quantities. The unstake fee is not accounted for in these calculations.

Balance

function balanceOf(address user) public view returns (uint256);

The staking contract doubles as an ERC20, which supports balanceOf and other operations. The number of decimals of flashHYPE is 18.
