Initialize SDK overview
Push Chain SDK enables seamless integration with Push Chain, a Proof-of-Stake layer 1 blockchain optimized for building hyper-scalable, consumer-centric web3 applications. This guide covers the installation and initialization of the SDK.
Initialize Push Chain API
- js
- react
- reactnative
// Import Push Chain SDK for blockchain interactions
import { PushChain, CONSTANTS, createUniversalSigner, createUniversalAccount } from '@pushchain/devnet';
// Import utility functions from viem
import { hexToBytes } from 'viem';
import { privateKeyToAccount, generatePrivateKey } from 'viem/accounts';
const privateKey = generatePrivateKey(); // Replace it with your private key generation logic
const account = privateKeyToAccount(privateKey);
// Create Signer. Defaults to Ethereum Sepolia
const signer = createUniversalSigner({
address: account.address,
signMessage: async (data) =>
hexToBytes(await account.signMessage({ message: { raw: data } })),
});
const pushChain = await PushChain.initialize(signer);

const pushChain = await PushChain.initialize(signer);
Note: If signer is not provided or is
null, then the SDK will switch to read-only mode. This means that you can only read data from the blockchain and not send transactions.
Initialize Push Chain parameters
When initializing your Push Chain instance, you can customize the process using several parameters. Here's a breakdown:
| Param | Type | Default | Remarks |
|---|---|---|---|
universalSigner | UniversalSigner | null | Signer responsible for signing when sending transactions. Only used for send function |
options.network | ENV | devnet | Push Chain environment |
