A developer looking to test a newly launched Layer 2 network no longer needs to hunt through Discord channels or forums for potentially outdated or incorrect network configuration details. Instead, they can simply visit the Chainlist website, search for the network name, and click "Connect to MetaMask." The entire process of adding the network is completed securely and seamlessly.
Chainlist has become an indispensable part of the Web3 infrastructure. This community-driven open-source project helps users worldwide streamline their connection to the multichain ecosystem.
Challenges and Solutions in the Multichain Ecosystem
The crypto landscape is no longer dominated by Ethereum alone. Today, dozens of blockchain networks—including Polygon, BSC, Arbitrum, Optimism, and Avalanche—coexist, creating a vibrant yet complex multichain ecosystem. This decentralized network structure presents a practical challenge: How can users seamlessly switch between different blockchains?
Many newcomers to blockchain find themselves overwhelmed by a slew of confusing RPC parameters. Manually entering network configurations is not only tedious but also highly error-prone, especially when dealing with testnets or newer blockchains.
Entering technical parameters by hand can also pose security risks. An incorrect RPC endpoint might connect a wallet to a malicious network, potentially resulting in asset loss.
Chainlist: Foundational Infrastructure for Simplified Multichain Connectivity
Chainlist is a free, open-source platform designed to provide users with a simple and reliable way to add various blockchain networks to Ethereum Virtual Machine (EVM)-compatible wallets. Its core function is to serve as a verified directory for EVM-compatible blockchain networks, currently supporting over 385 blockchains.
Chainlist operates in a straightforward and secure manner. Users visit the official site, connect their wallet, search for the desired network, and click the "Add to Wallet" button. The platform’s main value lies in its streamlined process—it eliminates the need to manually copy and paste network parameters, automatically handling the input of crucial configuration details like chain ID, RPC URL, and block explorer URL.
As an open-source project, Chainlist’s codebase is hosted on GitHub, allowing anyone to review, audit, or contribute to the project. This transparency significantly boosts its credibility within the Web3 developer community.
MetaMask: The Bridge to Web3
MetaMask is one of the world’s most popular cryptocurrency wallets and has become the de facto standard for connecting to the Web3 universe. As of January 2026, this wallet—launched by ConsenSys—has earned the trust of over 100 million users for buying, selling, and managing digital assets.
MetaMask is more than just a wallet; it’s a powerful gateway that enables users to interact with thousands of decentralized applications. The wallet supports a wide range of networks, including Ethereum, Linea, BSC, zkSync, Base, Arbitrum, Solana, Avalanche, and Polygon. Its versatility shines in its ability to store and manage thousands of tokens, including ETH, USDC, USDT, wBTC, and many more.
While MetaMask comes preloaded with several mainstream networks, its default list doesn’t include every available blockchain. Users often need to manually add specific networks to interact with certain dApps, which is why tools like Chainlist are essential for extending MetaMask’s functionality.
The Perfect Pair: Chainlist and MetaMask
Combining Chainlist with MetaMask delivers a seamless multichain experience for users. This synergy is especially valuable for DeFi users, NFT collectors, and developers who frequently switch between different networks.
In most real-world scenarios, Chainlist’s most popular feature is its integration with MetaMask. The connection process is simple and intuitive: On the Chainlist website, click "Connect Wallet," select MetaMask, and authorize the connection. One of Chainlist’s main conveniences is its "one-click wallet integration." After searching for the desired network, users can simply click "Add to MetaMask," and all necessary parameters are automatically populated in the wallet.
Chainlist is particularly useful for developers. For example, adding the Sepolia network—the main Ethereum testnet for developers—can be done effortlessly through Chainlist. Similarly, Coinbase’s Layer-2 solution Base is also listed on Chainlist, allowing users to add it to their wallet with a single click. This makes it easy to experiment on low-cost, high-speed networks.
Security Guidelines and Best Practices
Chainlist’s security is widely recognized, but users should still follow basic safety practices. The key principle is to use only the official website and stay vigilant against phishing sites that mimic the original. Users should understand that Chainlist is a non-custodial tool—it will never ask for your private key or seed phrase. It interacts only with your wallet’s public interface, requesting permission to add networks.
To further enhance security, users are advised to prioritize well-known networks when adding new ones to MetaMask. Before using new or unverified chains, always confirm RPC information through official chain documentation or GitHub repositories.
When dealing with testnets or unknown RPCs, it’s wise to use a separate test wallet instead of your primary one. Notably, while Chainlist itself does not provide faucet services, many listed testnets such as Sepolia include links to external faucets. These links allow developers to claim free testnet tokens for development purposes.
Gate: The Ideal Gateway for Secure Multichain Exploration
Once you’ve mastered tools like Chainlist and MetaMask for navigating the multichain world, your next logical step is to choose a secure, efficient, and asset-rich platform for trading and managing your holdings. As a leading global cryptocurrency exchange, Gate is built to meet this very need.
