## Introduction

This tutorial will show you how to transfer Ethers using code rather than Metamask. The implementation makes use of the ethers library, which allows JavaScript to interact with Ethereum networks and contracts.

\
Upon completion, you will have gained a deeper understanding of how to programmatically transmit Ethers and will have a working sample for future reference.

\
## Sending Ethers without Metamask

Here is a full code performing a programmatic transaction of ethers between accounts.

\
Let's start by taking a closer look at the code and understanding how it works.

Clone this repository into your preferred working directory using the command below. Make sure you have NodeJs and Git Bash installed on your local machine before proceeding with these steps.

\
```bash
git clone https://github.com/Daltonic/tailwind_ethers_starter_kit <PROJECT NAME>
```

\
Next, you need to install the packages using `npm install` or `yarn install` on that project directory.

\
Next, create a file at the root of this project called `transactions.js` and start by importing the `**ethers**` library from hardhat:

\
```javascript
const { ethers } = require('hardhat')
```

\
Next, it defines two helper functions, `**toWei**` and `**fromWei**`, to convert between Ether and its smallest unit, Wei. This is important because the Ethereum network operates in Wei, so we need to make sure the amounts we send are in Wei.

\
```javascript
const toWei = (num) => ethers.utils.parseEther(num.toString())
const fromWei = (num) => ethers.utils.formatEther(num)
```

\
These two functions, `**toWei**` and `**fromWei**`, convert between ether and wei. `**toWei**` converts a value in ether to its equivalent in wei, and `**fromWei**` does the opposite. The `**parseEther**` and `**formatEther**` methods from the `**ethers.utils**` the module is used for this conversion.

\
```javascript
const sendEthers = async (recipientAddress, amountInWei) => {
  return new Promise(async (resolve, reject) => {
    const privateKey =
      '0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80';
    const provider = new ethers.providers.JsonRpcProvider(
      'http://localhost:8545',
    );
    const wallet = new ethers.Wallet(privateKey, provider);
    const gasPrice = provider.getGasPrice();
    const nonce = provider.getTransactionCount(wallet.address, 'latest');
    const transaction = {
      to: recipientAddress,
      value: amountInWei,
      gasPrice,
      gasLimit: ethers.utils.hexlify(100000),
      nonce,
    };
    await wallet
      .sendTransaction(transaction)
      .then((transactionHash) => resolve(transactionHash))
      .catch((error) => reject(error));
  });
};
```

\
The `**sendEthers**` function is defined to send ethers from one wallet to another. It takes two parameters: `**recipientAddress**` and `**amountInWei**` which represent the address of the recipient and the amount to be sent, respectively.

\
A `**privateKey**` and a `**provider**` are created. The transaction is signed with the private key, and the provider communicates with the Ethereum network. Using the private key and the provider, a `wallet` instance is created.

\
The provider's `getGasPrice` and getTransactionCount methods are used to obtain the current `gasPrice` and nonce of the wallet, respectively. The `gasPrice` represents the cost of one unit of gas, and the nonce represents the number of transactions sent from the wallet.

\
A `**transaction**` object is created with the following parameters: `**to**` (recipientAddress), `**value**` (amountInWei), `**gasPrice**`, `**gasLimit**` (100000 in hex), and `**nonce**`. The `**sendTransaction**` method of the `**wallet**` instance is then used to send the transaction.

\
If the transaction is successful, the promise resolves with the transaction hash, otherwise it rejects with an error.

\
```javascript
const getBalance = async (walletAddress) => {
  return new Promise(async (resolve, reject) => {
    const provider = new ethers.providers.JsonRpcProvider(
      'http://localhost:8545',
    )
    await provider
      .getBalance(walletAddress)
      .then((balanceInWei) => resolve(balanceInWei))
      .catch((error) => reject(error))
  })
}
```

\
The `**getBalance**` function returns a promise that resolves with the balance of a wallet in wei. The function creates a JsonRpcProvider object and calls the `**getBalance**` method on it.

\
The method takes the address of the wallet as an argument. The `**getBalance**` method returns a Promise that resolves with the balance of the wallet in wei. If an error occurs, the Promise is rejected with the error.

\
```javascript
async function main() {
  // the rest of the codes goes in here
}
```

\
The `**main**` function is defined to perform the transfer of ethers.

\
```javascript
;[sender, receiver] = await ethers.getSigners()
const amountInWei = toWei(4.7)

console.log('\n')
let balance = await getBalance(sender.address)
console.log('Sender balance before transfer: ', fromWei(balance))
balance = await getBalance(receiver.address)
console.log('Receiver balance before transfer: ', fromWei(balance))
console.log('\n')
```

\
The `**ethers.getSigners**` method is called to obtain the sender and receiver addresses. The amount to be sent is converted to wei using the `**toWei**` function.

\
The balance of the sender and receiver is logged before the transfer by calling the `**getBalance**` function twice and pass the addresses of the sender and receiver as arguments.

\
```
await sendEthers(receiver.address, amountInWei).then((data) =>
  console.log('Transaction Details: ', data),
)
console.log('\n')
```

\
The `**sendEthers**` function is called to initiate the transfer of ethers. The function takes the recipient's address and the amount in wei as arguments.

\
The `**sendEthers**` function returns a Promise that resolves with the transaction details. This Promise is logged into the console.

\
```javascript
balance = await getBalance(sender.address)
console.log('Sender balance after transfer: ', fromWei(balance))
balance = await getBalance(receiver.address)
console.log('Receiver balance after transfer: ', fromWei(balance))
console.log('\n')
```

\
The balance of the sender and receiver is logged again to show that the transfer was successful. The `**getBalance**` function is called twice to obtain the balance of the sender and receiver after the transfer. The result is logged onto the console.
