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

Installation

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

npm install @chorus-one/near --save

Usage

Here is a basic example of how to use the Chorus One SDK to build, sign, and broadcast a staking transaction using Fireblocks as the signer.

// Configuration
// -------------

import { NearStaker, CHORUS_ONE_NEAR_VALIDATOR } from '@chorus-one/near'

const staker = new NearStaker({
  networkId: 'mainnet',
  rpcUrl: 'https://rpc.mainnet.near.org'
})

await staker.init()

// Building the transaction
// ------------------------

const delegatorAddress = 'your.near'

// You can use the Chorus One validator address or specify your own
const validatorAddress = CHORUS_ONE_NEAR_VALIDATOR
// 'chorusone.poolv1.near'

const { tx } = await staker.buildStakeTx({
  delegatorAddress,
  validatorAddress,
  amount: '1' // 1 NEAR
})

// Signing the transaction with Fireblocks
// ---------------------------------------

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

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

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

// Broadcasting the transaction
// ----------------------------

const {
  transaction: { hash: txHash }
} = await staker.broadcast({ signedTx })

// Tracking the transaction
// ------------------------

const { status, receipt } = await staker.getTxStatus({
  address: delegatorAddress,
  txHash
})

console.log(status) // 'success'
