In the rapidly expanding world of blockchain technology, understanding ChainIDs is essential for developers, decentralized application (dApp) creators, and crypto enthusiasts. A ChainID uniquely identifies a blockchain network within the Ethereum Virtual Machine (EVM) ecosystem, preventing transaction replay across chains and ensuring secure cross-chain interactions.
This guide presents a curated list of active blockchain networks, their ChainIDs, and native currencies—offering a reliable reference for wallet configuration, dApp development, and network integration.
What Is a ChainID?
A ChainID is a unique numerical identifier used in EVM-compatible blockchains to distinguish one network from another. It plays a critical role in transaction signing: without the correct ChainID, transactions can be misrouted or even replayed on unintended chains, leading to potential fund loss.
For example:
- Ethereum Mainnet uses ChainID
1 - Binance Smart Chain uses ChainID
56 - Polygon uses ChainID
137
Using the correct ChainID ensures compatibility with wallets like MetaMask, hardware signers, and smart contract deployment tools.

Frequently Asked Questions (FAQ)
What is the purpose of a ChainID?
A ChainID prevents transaction replay attacks between different blockchains. It ensures that a transaction signed on one network cannot be valid on another, enhancing security across EVM-compatible systems.
How do I add a custom RPC using ChainID?
In wallets like MetaMask:
- Go to "Networks" > "Add Network".
Enter network details including:
- Network Name
- New RPC URL
- ChainID
- Currency Symbol
- Block Explorer URL
- Confirm and save.
Ensure all fields match official sources to avoid phishing risks.
Can two blockchains have the same ChainID?
No. Each EVM-compatible blockchain must use a unique ChainID. Duplicate IDs would cause transaction conflicts and compromise security.
Why do some ChainIDs have very large numbers?
Large ChainIDs (e.g., over 1 trillion) are typically used for testnets or experimental chains. They help avoid collisions with mainstream networks and signal non-production status.
Is ChainID the same as Network ID?
Not exactly. While often used interchangeably, Network ID was used in earlier Ethereum implementations. Today, ChainID is the standard for transaction signing, whereas Network ID may refer to peer-to-peer network segregation.
How can I verify a ChainID’s legitimacy?
Always cross-reference ChainIDs with official documentation, GitHub repositories, or trusted databases like chainlist.org. Avoid unverified third-party lists to prevent wallet compromise.
