Web3 Wallets: The direct access gateway to the blockchain
It is important not to confuse Web3 Wallets with electronic payment wallets or Digital Wallets typically available in the form of mobile apps.
Blockchain, besides denoting a specific type of technology, refers to a group of networks that operate on the Internet based on private (in principle) infrastructure (hardware and software), on which third parties also develop, but to which anyone can access with a minimum of knowledge and simple equipment.
To gain access to these public networks, specific tools are required: Web3 Digital Wallets.
Although their name suggests they are used to “store” values, the truth is that they are merely the anchoring and access device that stores the cryptographic keys that allow access to and eventually control of assets located on the blockchain.
When we talk about a Web3 Wallet, it is primarily a piece of specialized software (sometimes interconnected with hardware as in the case of “cold wallets” that we will see later) that becomes our unique reference point for the operations we perform on the blockchain.
They consist of two types of character groups: Public Key and Private Key. The Public Key is represented by a unique sequence of characters (alphanumeric string, such as: 0x2g45b…ef3c) composed of up to 40 positions, which becomes our identifier (something like the account number given to us by a banking institution) and is the one we share with third parties when we want them to transfer a crypto asset to our “account (the Web3 Wallet)”; and on the other hand, a smaller group of characters that will be the Private Key, which is confidential and not shared with anyone, allowing us to activate access to the Web3 Wallet.
