API: Access Based Apps data, query states, and retrieve operational information
Utils: Helper functions for calculating Participants' Weights and other miscellaneous tasks

Installation

npm i @ssv-labs/bapps-sdk

# Using yarn
yarn add @ssv-labs/bapps-sdk

# Using pnpm
pnpm install @ssv-labs/bapps-sdk

Quick Start

Initialize the SDK

import { BasedAppsSDK } from "@ssv-labs/bapps-sdk";
import { createPublicClient, createWalletClient, http } from 'viem'
import { privateKeyToAccount } from 'viem/accounts'

// Setup viem clients
const chain = chains.mainnet // or chains.holesky
const transport = http()

const publicClient = createPublicClient({
  chain,
  transport,
})

const account = privateKeyToAccount('0x...')
const walletClient = createWalletClient({
  account,
  chain,
  transport,
})

const sdk = new BasedAppsSDK({
   beaconchainUrl: 'https://example.com/beacon',
   publicClient,
   walletClient,
 })

Based App Manager Contract Call example

const receipt = await sdk.core.contracts.bapp.write.delegateBalance({
    args: {
      account: "0xA4831B989972605A62141a667578d742927Cbef9",
      percentage: 10,
    },
  }).then((tx) => tx.wait())

API Example

// get validator balance of a given account
const validatorBalance = await sdk.api.getValidatorsBalance({
    account: '0x77fc6e8b24a623725d935bc88057098d0bca6eb3',
});

console.log('response:', validatorBalance)

Utils example

const strategiesWeights = await sdk.utils.getParticipantWeights({
  bAppId: '0x64714cf5db177398729e37627be0fc08f43b17a6',
})

console.log('response:', strategyTokenWeights)
