Ethereum: how to send / receive bitcoins from the cold wallet
As a beginner in the world of cryptocurrencies, the production of a cold wallet is an essential step. In this article, we guide you from the process of sending and receiving bitcoins of the cold portfolio of the generated etherum (ETH).
What is a cold wallet?
Cold Wallet is a digital portfolio that offline the private keys, which is not connected to the Internet or another network. This ensures that cryptocurrencies remain safe and that unauthorized people cannot access.
step by step to send / receive bitcoins from the cold wallet
1. Make a new Ethereum address
To start, you need to generate a new Ethereum address using Ethaddress aircraft (available online). This provides you with a unique public and private keyboard that can be used to send and receive ETH.
[Example:] (https: //etherscan.io/addr? Addr = 0x …) Make a new Ethereum address: 0x ... `
2. Copy the public key
Copy the first part of the title generated, which is the public key (or the title). For example, if the title is0x1234567890abcdef”, the public key would be 0x1234567890abcdef.
[Example:] (https: //etherscan.io/addr? Addr = ... and pk ...) Copy the first part of the title of Ethereum:[0x1234567890abcdef]
3. Create a transaction
To send or receive bitcoins, you must create a transaction using the public key (or address). You can use the "Ethers.js" directory (available online).
[Example:] ( Use the detail of the following code as an example:
Javascript
Const eethhers = require ("ethers");
// Create a new Ethereum account using the public key
Const wallet = New Ethers.Wallet ([0x1234567890abcdef], 'Any256');
CONST-COMPT = WALLET.Getaccount ();
// Generate a new transaction to send 10 ETH to the recipient's address
Const tx = wait for the account.sendtransection ({{
Sender: account.ddress,
To: [0x ...],
Value: Ethers.utils.Towei ('1', 'ether') ,,
});
// Send the transaction
tx.send ({sign: 'my_secret_key_here'});
'
Important aspects
* Private Keys: Always keep your private keys safely. Keep them in a safe place and never share them with anyone.
* Cold wallet safety:
Make sure that the cold wallet is physically fixed, such as storage in a flame retardant box or storage of a material wallet (like the big book). Avoid leaving the cold online wallet.
* Block IP address: Define the IP address when sending Ethereum nodes. This helps prevent the spammer network with malicious activities.
Bitcoins receives
To get some somebath bitcoins, you have to follow these steps:
- Create a new transaction using the private key (or portfolio) and send it to the recipient's portfolio.
- Define the payment method on your recipient's portfolio.
[Example:] (https: //etherscan.io/addr? Addr = ... and pk ...) Use the details of the following code as an example:
Javascript
Const eethhers = require ("ethers");
// create a new Ethereum account using the private key
Const wallet = New Ethers.Wallet ([0x1234567890abcdef], 'Any256');
CONST-COMPT = WALLET.Getaccount ();
// Define the payment method on your recipient's portfolio
Wallet.sendtransection ({
To: [0x ...],
Value: Ethers.utils.Towei ('1', 'ether') ,,
});
// Create a new transaction from the private key to the sender and send it to the recipient
tx = awaiting your account.sendtransection ({{
Sender: account.ddress,
To: [0x ...],
Value: Ethers.utils.Towei ('1', 'ether') ,,
});

conclusion
Sending and receiving Bitcoins of a cold wallet is a safe process that requires basic knowledge of Ethereum.
