Get Wallet Address

Fetching a wallet address

The getWallet function returns the wallet address for a given private key.

Basic Syntax

The function is called as follows:

import { getAddress } from 'arweavekit/wallet'

const address = await getAddress({params});

Input Parameters

The following params are available for this function:

• key: JWKInterface : The private key for the wallet address to be fetched. The wallet key file can be loaded as follows:

import { readFileSync } from 'fs';

const key = JSON.parse(readFileSync('wallet.json').toString());

Private keys must be kept secure at all times. Please ensure that the wallet.json file is not pushed to a version control (eg. GitHub).

It is important to JSON.parse the read file as this returns the key in the correct format (object) for further use.

• environment: 'local' | 'mainnet' : The active environment on which the wallet is interacting with.

An arlocal instance must be running on port 1984 for the function to work with the local environment. To create one, simply run npx arlocal in the command line. Learn more about arlocal here.

Example

const walletAddress = await getAddress({
    key: { KEY_OBJECT },
    environment: 'local',
});

This returns the wallet address of the key entered as part of the parameters for the chosen environment.

Returned Data

The function call returns the following data:

'WALLET_ADDRESS'

• address: string : The wallet address corresponding to the private key input is returned as type string.
