Chainlist - An indispensable multi-chain blockchain connection tool for Web3 users

In the modern Web3 ecosystem with hundreds of blockchains operating simultaneously, managing and connecting wallets to different networks has become complex. Chainlist was created as an optimal solution, allowing Web3 users to automate this process with just a few clicks.

What problem does Chainlist solve in Web3?

Web3 often encounters “network mismatch” errors when users see “Chain ID not recognized” or incorrect network configurations. This issue occurs because each EVM blockchain (Ethereum, Polygon, Arbitrum, Optimism, BNB Chain, Base, Blast, zkSync, etc.) has its own set of information, including Chain ID, network name, RPC URL, currency symbol, and Block Explorer URL.

Chainlist addresses this by providing a centralized, community-verified database (with over 100K contributors). Instead of manually searching for each parameter, users can simply visit Chainlist and add networks to their wallets in seconds.

How does Chainlist automate adding blockchain networks?

Chainlist functions as an aggregator of EVM network data, continuously updated by the Web3 community and maintained by developers. The process is straightforward:

• Step 1: Connect your Web3 wallet (MetaMask, Rabby Wallet, Coinbase Wallet, Frame, etc.) to Chainlist
• Step 2: Search for the desired network from a database of over 1,000 Chain IDs
• Step 3: Click “Add to Wallet” and confirm (Approve) in your wallet
• Step 4: Chainlist automatically adds the Chain ID, RPC URL, and Block Explorer to your wallet within seconds

Thanks to open-source code on GitHub, Chainlist is maintained by the community, ensuring data accuracy and transparency.

Detailed steps for using Chainlist

Connect your wallet to Chainlist:

• Visit the official site: chainlist.org

Security tips when using Chainlist

Always verify official sources: Access chainlist.org directly from the address bar; avoid clicking links from unknown sources to prevent phishing.

Do not paste unknown RPC URLs: Only use verified RPC URLs from Chainlist. Never paste URLs from untrusted or unverified sources.

Prioritize verified Chain IDs: Always select Chain IDs confirmed by the community, usually marked with a green checkmark next to the network name.

Protect your seed phrase: Chainlist is a network management tool and does not require entering your seed phrase. If any site asks for it, exit immediately to avoid asset loss.

Check network details: Before confirming, double-check the Chain ID and RPC URL to ensure they match the network you intend to add.
