🔌 CONNECT TO AN EXISTING ACCOUNT

Once your provider is initialized, you can connect an existing account.

You need 2 pieces of data:

 * the address of the account
 * the private key of this account

import { Account, Provider } from 'starknet';





CONNECT TO A PRE-DEPLOYED ACCOUNT IN STARKNET-DEVNET

When you launch starknet-devnet, 10 accounts are pre-deployed with 100 dummy ETH
in each.

Addresses and private keys are displayed on the console at initialization.

> This data will change at each launch, so to freeze them, launch with:
> starknet-devnet --seed 0.

The result for account #0:

Address: 0x7e00d496e324876bbc8531f2d9a82bf154d1a04a50218ee74cdd372f75a551a
Public key: 0x7e52885445756b313ea16849145363ccb73fb4ab0440dbac333cf9d13de82b9
Private key: 0xe3e70682c2094cac629f6fbed82c07cd




Then you can use this code:

// initialize provider
const provider = new Provider({ sequencer: { baseUrl: 'http://127.0.0.1:5050' } });
// initialize existing pre-deployed account 0 of Devnet
const privateKey = '0xe3e70682c2094cac629f6fbed82c07cd';
const accountAddress = '0x7e00d496e324876bbc8531f2d9a82bf154d1a04a50218ee74cdd372f75a551a';

const account = new Account(provider, accountAddress, privateKey);




Your account is now connected, and you can use it.

> IMPORTANT: If this account is based on a Cairo v2 contract (for example
> OpenZeppelin account 0.7.0 or later), do not forget to add the parameter "1"
> after the privateKey parameter:

const account = new Account(provider, accountAddress, privateKey, '1');




> Take care that this added parameter is a string, NOT a number.


👛 CONNECT TO AN EXISTING ACCOUNT (IN ANY NETWORK)

The code is the same, you just have to:

 * connect to the appropriate network.
 * use the address of this account (public data).
 * use the private key of this account (very sensitive data: your code MUST not
   disclose it).

For example, to connect an existing account on testnet, with a private key
stored in a .env non-archived file:

import * as dotenv from 'dotenv';
dotenv.config();

// initialize provider
const provider = new Provider({ sequencer: { network: constants.NetworkName.SN_GOERLI } });
// initialize existing account
const privateKey = process.env.OZ_NEW_ACCOUNT_PRIVKEY;
const accountAddress = '0x051158d244c7636dde39ec822873b29e6c9a758c6a9812d005b6287564908667';

const account = new Account(provider, accountAddress, privateKey);
// add ,"1" after privateKey if this account is not a Cairo 0 contract
