Chorus One SDK: Hyperliquid

All-in-one toolkit for building staking dApps on Hyperliquid network.

Documentation

For detailed instructions on how to set up and use the Chorus One SDK for Hyperliquid staking, please visit our main documentation.

Installation

In the project's root directory, run the following command:

``bash
npm install @chorus-one/hyperliquid
`

Usage

Here is a basic example of how to use the Chorus One SDK to build, sign, and broadcast staking transactions on Hyperliquid.

$3

`javascript
import { HyperliquidStaker } from '@chorus-one/hyperliquid'

const staker = new HyperliquidStaker({
chain: 'Testnet' // or 'Mainnet'
})
`

$3

`javascript
const delegatorAddress = '0xYourAddress'

// Get spot balances (HYPE and USDC)
const spotBalances = await staker.getSpotBalances({ delegatorAddress })
console.log(
'Spot HYPE Balance:',
spotBalances.balances.find((b) => b.coin === 'HYPE')
)
console.log(
'Spot USDC Balance:',
spotBalances.balances.find((b) => b.coin === 'USDC')
)

// Get staking summary
const summary = await staker.getStakingSummary({ delegatorAddress })
console.log('Delegated (staked to validators):', summary.delegated)
console.log('Undelegated (available in staking account):', summary.undelegated)
console.log('Total Pending Withdrawals:', summary.totalPendingWithdrawal)
console.log('Number of Pending Withdrawals:', summary.nPendingWithdrawals)

// Get staking rewards
const rewards = await staker.getDelegatorRewards({ delegatorAddress })

// Get delegation history (useful for verifying transaction success)
const history = await staker.getDelegatorHistory({ delegatorAddress })
`

$3

Move tokens from your spot account to staking balance:

`javascript
import { FireblocksSigner } from '@chorus-one/signer-fireblocks'

const signer = new FireblocksSigner({...})
await signer.init()

const { tx } = await staker.buildSpotToStakingTx({
amount: '100' // Amount in HYPE
})

const { signedTx } = await staker.sign({
signer,
signerAddress: delegatorAddress,
tx
})

const { txHash } = await staker.broadcast({
signedTx,
delegatorAddress
})
`

$3

Delegate tokens from your staking balance to a validator. Once delegated, there is a 1-day lockup period before you can undelegate those tokens:

`javascript
const validatorAddress = '0xValidatorAddress'

const { tx } = await staker.buildStakeTx({
validatorAddress,
amount: '50' // Amount in HYPE
})

const { signedTx } = await staker.sign({
signer,
signerAddress: delegatorAddress,
tx
})

const { txHash } = await staker.broadcast({
signedTx,
delegatorAddress
})
`

$3

Undelegate tokens from a validator (instant, returns tokens to staking account). Note: You must wait 24 hours after delegation before you can undelegate:

`javascript
const { tx } = await staker.buildUnstakeTx({
validatorAddress,
amount: '25' // Amount in HYPE
})

const { signedTx } = await staker.sign({
signer,
signerAddress: delegatorAddress,
tx
})

const { txHash } = await staker.broadcast({
signedTx,
delegatorAddress
})
`

$3

Move tokens from staking balance back to spot account (7-day queue, max 5 pending withdrawals):

`javascript
const { tx } = await staker.buildWithdrawFromStakingTx({
amount: '10' // Amount in HYPE
})

const { signedTx } = await staker.sign({
signer,
signerAddress: delegatorAddress,
tx
})

const { txHash } = await staker.broadcast({
signedTx,
delegatorAddress
})
`

Key Features

- REST API Based: Uses Hyperliquid's REST API endpoints (/info and /exchange)
- EIP-712 Signing: All transactions are signed using EIP-712 typed data
- Human-Readable Amounts: Pass token amounts as strings (e.g., '1.5'), conversion to 8-decimal wei format is handled automatically
- Query Methods: Read spot balances, staking data, delegations, rewards, and history
- Write Operations: Transfer between spot/staking, stake to validators, and unstake
- Lockup Periods:
- Delegations: 1-day lockup period before undelegation is allowed
- Undelegation: Instant (tokens return to staking account)
- Withdrawals: 7-day unstaking queue from staking to spot (max 5 pending withdrawals per address)
- Staking Rewards: Auto-compounded daily, ~2.37% APY (at 400M HYPE staked), distributed based on validator performance
- Validator Economics: Validators charge commissions (max 1% change per update), can be jailed for poor performance

Important Notes

- Token Amounts: Pass amounts as human-readable strings (e.g., '1.5' for 1.5 HYPE). The SDK automatically converts to Hyperliquid's 8-decimal wei format internally.
- Delegation Lockup: After delegating tokens to a validator, you must wait 24 hours before you can undelegate those specific tokens. After the lockup expires, undelegation is instant and returns tokens to your staking account.
- Transfer Characteristics:
- Spot → Staking: Instant transfers (no waiting period)
- Staking → Spot: 7-day unstaking queue (maximum 5 pending withdrawals per address)
- Transaction Confirmation: Hyperliquid API doesn't provide transaction status queries. Use getDelegatorHistory()` to verify transaction success.
- Staking Epochs: Staking epochs are 100,000 rounds (~90 minutes). Rewards are based on minimum balance held during each epoch.
- Reward Distribution: Rewards accrue every minute based on validator performance, are distributed daily with auto-compounding, and require no manual claiming
