wHLP Builder Codes

Integrate Wrapped HLP (WHLP) into your app to acquire users and earn fees.

Product Overview

wHLP is a tokenized wrapper of HyperLiquidity Provider (HLP). Users mint wHLP and earn HLP trading fees while keeping full DeFi composability on HyperEVM. Integrators earn fees for every deposit attributed to their unique communityCode. For CommunityCode flow, deposits are in USDHL.

If you plan to integrate wHLP, get in touch with the Looping Collective team on Telegram @loopingcollective to further discuss reward options.

Deposit Flow

ERC‑20 Deposits (USDHL)

The CommunityCodeDepositor exposes a single deposit function. The accepted deposit asset for this flow is USDHL.

USDHL.approve(COMMUNITY_CODE_DEPOSITOR, AMOUNT);

const minimumMint = getQuote(AMOUNT, TOKEN_ADDRESS)

const cc = encodeBytes(COMMUNITY_CODE ?? '')

const args = [TOKEN_ADDRESS, AMOUNT, minimumMint, ADDRESS, cc]

const writeContractProps = {
    contractAddress: DEPOSIT_CONTRACT,
    accountAddress: ADDRESS,
    value: 0n,
    abi: DEPOSIT_CONTRACT_ABI,
    functionName: 'deposit',
    args,
    gasLimit: <estimate>
}

Parameter	Type	Description
depositAsset	address	ERC‑20 token to deposit (USDHL)
depositAmount	uint256	Amount of token to deposit
minimumMint	uint256	Minimum wHLP shares to mint, reverts if minimumMint is too high (not enough slippage deduced from: depositAmount / rate)
to	address	Address to receive minted wHLP
communityCode	bytes32	Byte‑encoded integrator code

Minimum Mint Calculation

Compute the minimum number of wHLP shares to mint, factoring in slippage.

If the calculated minimumMint is too high, the deposit call will fail.

const maxSlippage = 0.000001
const quote = new BigNumber(AMOUNT)
    .times(new BigNumber(1 - maxSlippage))
    .div(WHLP_EXCHANGE_RATE)

• WHLP_EXCHANGE_RATE is fetched via Accountant.getRateInQuote(assetAddress).

• maxSlippage defines your worst acceptable deviation.

Exchange Rate & Swap vs Mint

Before depositing, you may choose between swapping on a DEX or depositing natively:

const rate = accountant.getRateInQuote(USDHL);

Decide based on:

1. Order size (large orders may incur DEX price impact)

2. Market rate vs native rate (if on-chain swap is cheaper)

Withdrawal Flow

Requesting a Withdrawal

To redeem wHLP back to USDHL, submit/modify a request via the Atomic Queue (UCP). Solvers process requests periodically.

WHLP.approve(ATOMIC_QUEUE_CONTRACT, AMOUNT);

const threeDays = 5 * DAY_IN_SECONDS
const deadline = Math.floor(Date.now() / 1000) + threeDays
const atomicPrice = new BigNumber(1 - MAX_SLIPPAGE).times(WHLP_EXCHANGE_RATE)

const args = [
    WHLP,
    USDHL,
    [deadline, ATOMIC_PRICE, AMOUNT, false],
]

const writeContractProps: WriteContractProps = {
    contractAddress: ATOMIC_QUEUE_CONTRACT,
    accountAddress: ADDRESS,
    value: 0n,
    abi: ATOMIC_QUEUE_CONTRACT_ABI,
    functionName: 'updateAtomicRequest',
    args,
    gasLimit: <estimate>
}

Parameter	Type	Description
offer	address	Asset to withdraw from (wHLP)
want	address	Desired asset (USDHL)
deadline	uint64	Unix timestamp after which the request expires
atomicPrice	uint88	Solver price quote
offerAmount	uint96	Amount of wHLP to redeem
inSolve	bool	Used during solves to prevent duplicate users, and to prevent redoing multiple checks

• Solver frequency: ~10 min

• Min. delay: 0 days

• Expiry period: configurable by you (e.g. 5 days)

Querying & Cancelling Requests

• Fetch pending/fulfilled/cancelled requests using the Nucleus API:

GET https://backend.nucleusearn.io/v1/protocol/withdrawals
  ?chainId=999
  &vaultAddress=0x1359b05241cA5076c9F59605214f4F84114c0dE8
  &user=0xYourUserAddress
  &status=all
  &all=true

• Cancel an existing request by revoking wHLP approval or submitting a new request (automatically cancels prior pending request).
