What is Ethernova Mainnet?

Ethernova Mainnet is an EVM (Ethereum Virtual Machine) compatible blockchain network. Any EVM wallet — MetaMask, Rabby, OKX Wallet, Trust Wallet, Coinbase Wallet — can connect and transact on Ethernova Mainnet once you add the network configuration.

Why do you need to add Ethernova Mainnet to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on Ethernova Mainnet, you need to add the network first. Entering an incorrect Chain ID or RPC can put your assets at risk. Use the "Add to wallet" button above — data sourced directly from chainid.network, the canonical Ethereum chain registry.

How to add Ethernova Mainnet to your wallet

  1. 1

    Click Add to wallet

    Press the "Add to wallet" button above. MetaMask, OKX Wallet, Rabby Wallet or Trust Wallet will show a popup asking you to confirm adding the Ethernova Mainnet network.

  2. 2

    Confirm in your wallet

    Your wallet shows the Ethernova Mainnet network details: Chain ID 121525, native token NOVA. Verify the Chain ID is correct, then click "Approve" or "Add Network".

  3. 3

Frequently asked questions

Is it safe to add Ethernova Mainnet to MetaMask?▾
Yes, if you use the "Add to wallet" button on this page. Data is sourced from chainid.network — the community-audited Ethereum registry. Adding a network does not expose your private key or grant any permissions to the dApp.
What is Ethernova Mainnet Chain ID?▾
The Chain ID of Ethernova Mainnet is 121525. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need NOVA tokens to use Ethernova Mainnet?▾
Yes. Every transaction on Ethernova Mainnet requires NOVA to pay gas fees. You can purchase NOVA on exchanges and bridge it to Ethernova Mainnet, or use a faucet if this is a testnet.
What is the Ethernova Mainnet RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Ethernova Mainnet blockchain — sending transactions, reading balances, and checking state. One popular Ethernova Mainnet RPC is https://rpc.ethnova.net. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Ethernova Mainnet already exists when I click Add — what do I do?▾
That's completely normal. If Ethernova Mainnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Ethernova Mainnet but the network won't load — what's wrong?▾
The most common cause is a broken or overloaded RPC endpoint. Your wallet uses RPC to connect to the blockchain — if the RPC is down, the network won't load even if it was added correctly. Fix: copy a different RPC from the list above (prefer green low-latency ones), then go to Settings → Networks in your wallet and replace the old RPC with the new one. Watch the tutorial video above for step-by-step instructions on updating your RPC.
