Chainslist is an open registry of EVM networks — it collects the exact settings a wallet needs to connect to a blockchain: network name, chain ID, RPC endpoint, native currency symbol and block explorer. Instead of copying those values from scattered docs, you search a network, connect a wallet, and add it in one click. Every entry can also be added manually if a wallet blocks automatic setup.
What is Chainslist?
Chainslist is an open registry of EVM networks that pairs each chain with the exact settings a wallet needs to connect: network name, chain ID, RPC URL, currency symbol and block explorer. It maintains a public, community-contributed list covering mainnets, testnets and long-tail chains.
Instead of hunting for network parameters, you search a chain, connect a wallet, and add it in one click — no account, sign-up or API key at any step. Chainslist supplies configuration only; it never takes custody of funds.
Chain IDs & RPCs
Every EVM network is identified by a unique chain ID — Ethereum is 1, Polygon 137, Arbitrum One 42161, Base 8453. An RPC endpoint is the URL your wallet sends requests to in order to read balances and broadcast transactions.
Chainslist pairs each chain ID with one or more working RPC URLs so a wallet can connect without manual configuration errors. A single chain can have many RPCs run by different providers, so you can switch endpoints if one is slow or offline.
How to add a network
Open Chainslist, search for the chain by name or chain ID, and connect your wallet. Select an RPC endpoint and click Add to MetaMask (or your wallet). Your wallet then shows an add-network prompt listing the network name, chain ID, RPC URL and currency symbol — review those values and approve.
The network is now selectable in your wallet. If an RPC is slow or returns errors, open the same entry and choose a different endpoint for the identical chain ID, then re-add or edit the network in your wallet's settings.
Public RPC endpoints
The RPC endpoints Chainslist lists are public and keyless: you connect without an API key or account. They are community-run and convenient for quick setup, wallet connection and testing.
Public RPCs are rate-limited and shared, so for production apps, high-volume reads or privacy-sensitive usage a dedicated managed RPC provider is the better choice. Use Chainslist to discover the correct chain ID and confirm a network exists, then point your application at a reliable node.
Security & safe setup
Chainslist is non-custodial: it never holds funds, never asks for a seed phrase or private key, and only supplies network configuration your wallet applies. The real risk sits with the RPC endpoint.

Networks & wallets
Chainslist works with any EVM-compatible wallet, including MetaMask, Trust Wallet, Rabby and Coinbase Wallet. Its registry covers major layer-1s and layer-2s — Ethereum, Arbitrum, Base, Optimism, Polygon, BNB Chain — alongside a long tail of newer and testnet chains.
Because networks are added continuously, the live list is always the source of truth for whether a specific chain ID and RPC are available.
Chainslist FAQ
Is Chainslist safe to use?
Chainslist is non-custodial: it never holds your funds or asks for a private key. It only supplies network settings your wallet uses to connect. The main risk is a low-quality or malicious RPC, so confirm the chain ID against official docs and review the add-network prompt before approving.
Does Chainslist cost anything?
Chainslist is free and its public RPC endpoints are keyless — no account or API key required. You still pay standard gas fees in the native token when you transact.
What is a chain ID?
A chain ID is a unique integer that identifies an EVM network and prevents a transaction signed for one chain from being replayed on another. If it does not match the network, transactions can fail.
Why won't a network add to my wallet?
It can fail if the wallet is locked, the network already exists under a different RPC, the RPC is offline, or the wallet blocks programmatic additions. Unlock the wallet, choose a different RPC for the same chain ID, or add the network manually.
Can I add a custom network manually?
Yes. Every entry shows the network name, chain ID, RPC URL, currency symbol and block explorer, so you can enter them by hand instead of using the one-click button.
Which wallets does Chainslist work with?
Any EVM-compatible wallet — MetaMask, Trust Wallet, Rabby, Coinbase Wallet — across major layer-1s, layer-2s and testnets.
Notes before you connect
- Confirm the network name, chain ID and currency symbol in the wallet prompt.
- Prefer a well-known RPC endpoint; switch endpoints if one is slow or offline.
- Remember public RPCs are rate-limited — use a dedicated provider for production.
