What Is Chainlist: Chain IDs, RPC URLs and EVM Network Setup (2026)

May 22, 2026 — By Tony Rabbit in Tutorials

What is Chainlist? Learn how this EVM network directory helps users find chain IDs, RPC URLs and wallet connection details in 2026.

Intent check: If you are looking for a full wallet walkthrough, use our WalletConnect guide or a wallet-specific tutorial. This page is specifically about Chainlist as a chain ID and RPC discovery tool.

Chainlist is one of those tools that becomes obvious only after you have tried to add the right network details by hand. Its core job is simple but useful: help users and builders find the correct EVM network metadata, including chain IDs and RPC options, and connect wallets to the intended chain without as much guesswork.

That makes the search evergreen because wallet setup friction never fully disappears. New chains launch, RPC options change, users move across ecosystems and builders still need a clean way to verify which network details belong to which environment. Chainlist sits right in that recurring onboarding problem.

What Chainlist does in plain English

The best way to understand Chainlist is as a lookup layer for network configuration. Instead of hunting across docs, forum posts and random screenshots to confirm a chain ID or RPC entry, users can search Chainlist and review the network information in one place.

That does not make Chainlist a wallet, a node provider or a blockchain explorer. It is a coordination tool that helps people connect the right wallet setup to the right EVM-powered network. That narrower definition is exactly what keeps the page from overlapping with broader wallet education pieces.

Where it fits

Chainlist fits when the real question is “what network am I adding, and what are the correct chain details?” rather than “how do wallets work in general?”

Why teams look at Chainlist

Users care about Chainlist because it cuts down setup mistakes. Builders care because network onboarding is one of the first points where users can get confused, especially when moving between Ethereum, Base, Arbitrum, BNB Chain and newer EVM environments. A clean directory for chain IDs and RPC options can remove a surprising amount of friction from that step.

Focus 1

Chain ID lookup

The most common use case is confirming the right network identifier.

Focus 2

RPC discovery

Users often need an RPC option or at least a place to verify one exists.

Focus 3

Wallet setup help

Chainlist supports the network-connection part of onboarding, not the whole wallet experience.

Focus 4

EVM scope

The tool is strongest when the problem lives inside EVM network configuration.

How Chainlist fits into a Web3 stack

Chainlist sits closer to wallet setup and network configuration than to raw infrastructure operations. It is best treated as a discovery and onboarding helper, not as a replacement for nodes, providers or explorers.

Question	Why it matters	Chainlist angle
Do you need the right chain ID fast?	Wrong IDs cause failed or confusing setups.	Chainlist is built around surfacing that information clearly.
Do you need to compare network entries?	Users often switch between many EVM chains.	A searchable directory is cleaner than scattered docs.
Do you need a wallet tutorial from zero?	That is a broader education problem.	Chainlist helps with network setup, not the whole wallet lifecycle.
Do you need an actual RPC provider?	A directory is not the same thing as infrastructure.	Chainlist points you toward network details, it does not replace provider selection.

How this article avoids internal overlap

We already cover wallets, RPC basics and chain-specific explorer tutorials. If this article tried to become all of those things at once, it would cannibalize our own internal guides and lose the branded query focus.

The stronger approach is to keep Chainlist narrowly defined as a directory and setup helper: chain IDs, RPC options and wallet-network connection context for EVM users.

Cannibalization guardrail

This article is intentionally about Chainlist as a network directory and setup helper. It is not a complete MetaMask course and not a generic RPC explainer.

Who Chainlist is for, and where it can feel like overkill

Chainlist is useful for wallet users, builders and support teams that regularly need to verify network details or help others connect to the correct EVM chain quickly.

It is less relevant if the need is deep infrastructure control, advanced node operations or broad wallet security education. Those are adjacent but different problems.

Final take

Chainlist matters because onboarding friction often hides in tiny details like chain IDs and network metadata. A tool that reduces those mistakes stays useful even as chains, wallets and interfaces keep changing.

FAQ

Is Chainlist a wallet?

No. Chainlist is a network directory and setup helper, not a wallet application.

Does Chainlist replace RPC providers?

No. It helps surface network configuration and RPC options, but it is not the same as choosing or operating infrastructure.

Who uses Chainlist most?

Wallet users, builders and support teams dealing with EVM network setup and connection details.

Frequently Asked Questions

What is Chainlist used for?

Chainlist is a directory that helps users find EVM network details such as chain IDs and RPC URLs, and add them to wallets like MetaMask. It is commonly used to quickly configure a wallet for a new network.

What is a chain ID?

A chain ID is a unique number that identifies a specific EVM network and helps prevent transactions intended for one chain from being replayed on another. Wallets use the chain ID to know which network they are connected to.

How do I add a custom network to my wallet?

You typically enter the network name, RPC URL, chain ID, currency symbol, and block explorer URL in your wallet settings. Tools like Chainlist can fill these details automatically to reduce manual entry errors.

Is it safe to use any RPC URL I find online?

Not always, because a malicious or unreliable RPC endpoint could log activity or serve incorrect data. It is safer to use RPC URLs from reputable sources and to verify the chain ID matches the intended network.
