mnemonic	string	A mnemonic phrase used for generating the wallet's private key.
env	string	A string indicating the blockchain network environment.
ecc	any	An elliptic curve cryptography library or object.

Response

Field	Data Type	Description
code	number	Indicates the status code. 1 for success, 0 for error.

Example Request and Response

Prerequisites

Before making requests with Nest SDK, you must have it installed.

You can install Nest SDK using either npm or yarn. Use the following commands to install Nest SDK:

npm install @nest25/wallet-lib
OR
yarn add @nest25/wallet-lib

Request

Here is an example of how to make a getBalanceByMnemonicrequest using the Nest SDK:

const { Wallet } = require('@nest25/wallet-lib');

const wallet = new Wallet('');

async function main() {
    const response = await wallet.chainBalances("choice kidney aerobic derive chat recall ranch siege enemy certain hand dry");
    console.log( "response --> ",JSON.stringify(response));
}

main();

Response

   response -->  {"code":1,"balances":{"AVA":{"balance":0,"balanceInUSD":"0"},"BNB":{"balance":0,"balanceInUSD":"0"},"ETH":{"balance":0,"balanceInUSD":"0"},"KLAY":{"balance":0,"balanceInUSD":"0"},"MATIC":{"balance":0,"balanceInUSD":"0"},"VLRY":{"balance":0,"balanceInUSD":"0"},"AUR":{"balance":0,"balanceInUSD":"0"},"GLMR":{"balance":0,"balanceInUSD":"0"},"GNO":{"balance":0,"balanceInUSD":"0"},"OP":{"balance":0,"balanceInUSD":"0"},"ARB":{"balance":0,"balanceInUSD":"0"},"CELO":{"balance":0,"balanceInUSD":"0"},"SOL":{"balance":0,"balanceInUSD":"0"}}}

Use Cases

• Retrieving chain balances: By invoking this function with a mnemonic and environment, you can retrieve the balances of various cryptocurrencies on different blockchain networks.

• Error handling: The function performs various checks and validations throughout the process, returning an error object with an appropriate error message if any issues arise.

• Balances conversion: The function converts the raw balance values received from the external API to the corresponding currency balance and balance in USD for easier interpretation.
