If users want to enter the Web3 realm and interact with a blockchain, each user must authenticate themselves using a verification tool. While most users authenticate with MetaMask when interacting with Ethereum dapps (decentralized applications), the number one wallet to authenticate Solana users with is Phantom. That’s also the case when building Web3 apps. When you decide to build Ethereum dapps, you utilize MetaMask for developers, but when creating Solana dapps, you utilize the Phantom wallet to authenticate users. Since Solana might be the primary contender to all programmable blockchains, we’ve decided to provide a straightforward authentication solution to those who want to utilize its network. Thus, follow along as we discover how to authenticate Solana users with the Phantom wallet!
Herein, we will use Next.js to create a Moralis dapp that will authenticate Solana users. However, before we dive into this article’s example project, let’s go through some basics. We will first explore Solana authentication and cover the basics of the Phantom wallet. Moreover, to get ready for the upcoming tutorial, create your free Moralis account!
Exploring Solana Authentication
If you are new to Web3, you might wonder, “why is it necessary to authenticate users?”. Without digging too deep into the functionality of blockchain technology, you need to know that cryptography plays a vital role in the crypto realm. Further, there needs to be some sort of gateway that determines who gets to interact with any particular chain. This is where users’ wallet addresses come into the picture.
Web3 or crypto wallets come in many forms, although primarily, they are split into two categories: hot and cold wallets. Both types of wallets store a collection of keys and are used to receive, send, and track ownership of cryptocurrencies. When creating a new wallet, a key pair of a private key and a public key is securely generated. So, a wallet provides the means to interact with these keys. Furthermore, you ought to know that public keys are usually referred to as “wallet addresses”. The word “public” suggests that these addresses can be shared and displayed freely. For instance, you’d share this address with someone when you want them to send you some SOL tokens. In addition, public addresses are also what blockchain apps use to authenticate users. As such, it is important to use a wallet that supports the chain you want to interact with.
It’s essential to point out that not all wallets support all chains. For instance, you can’t authenticate with MetaMask on Solana. When you want to explore Solana authentication options, you need to check out Solana’s ecosystem. Moreover, when it comes to using crypto wallets to authenticate users for devs, wallets that offer browser extensions are the way to go. With that said, Phantom is currently the most popular tool to authenticate Solana users.
