Chorus One SDK: Substrate

All-in-one toolkit for building staking dApps on Substrate Network SDK blockchains(Polkadot, Kusama, etc.).

Documentation

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

Installation

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

npm install @chorus-one/substrate --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 { SubstrateStaker, RewardDestination, CHORUS_ONE_SUBSTRATE_VALIDATORS } from '@chorus-one/substrate'

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

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

const staker = new SubstrateStaker({
  rpcUrl: 'wss://rpc.polkadot.io',
  denomMultiplier: 1000000000000,
  rewardDestination: RewardDestination.STASH
})

await staker.init()

// Building the transactions
// -------------------------

const delegatorAddress = '5CavrskYZHeLxTwERikgZDCZPmhpsM7oXZQmL6rkNryDD8FwN'

// You can use the Chorus One validator address or specify your own
const validatorAddress = CHORUS_ONE_SUBSTRATE_VALIDATORS.POLKADOT[0]
// '16XF84j2wQ9wjkqRM2Y8ceCaw8dQu7t3ve9P9XbBj5kaRZxY'

const { tx: stakeTx } = await staker.buildStakeTx({
  amount: '1' // 1 DOT
})

const { tx: nominateTx } = await staker.buildNominateTx({
  validatorAddress
})

// Signing the transactions with Fireblocks
// ----------------------------------------

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

const { signedTx: signedNominateTx } = await staker.sign({
  signer,
  tx: nominateTx
})

// Broadcasting the transactions
// -----------------------------

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

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

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

console.log(status) // 'success'

// Closing the connection
// ----------------------

await staker.close()
