What is Hubble Exchange?

Hubble Exchange 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 Hubble Exchange once you add the network configuration.

Why do you need to add Hubble Exchange to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on Hubble Exchange, 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 Hubble Exchange 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 Hubble Exchange network.

  2. 2

    Confirm in your wallet

    Your wallet shows the Hubble Exchange network details: Chain ID 1992, native token USDC. Verify the Chain ID is correct, then click "Approve" or "Add Network".

  3. 3

    Switch to the new network

    After confirming, your wallet automatically switches to Hubble Exchange. You can start transacting right away — you will need USDC to pay gas fees.

  • •If the "Add to wallet" button doesn't work, your wallet may not support wallet_addEthereumChain — add the network manually using the details below

Frequently asked questions

Is it safe to add Hubble Exchange 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 Hubble Exchange Chain ID?▾
The Chain ID of Hubble Exchange is 1992. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need USDC tokens to use Hubble Exchange?▾
Yes. Every transaction on Hubble Exchange requires USDC to pay gas fees. You can purchase USDC on exchanges and bridge it to Hubble Exchange, or use a faucet if this is a testnet.
What is the Hubble Exchange RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the Hubble Exchange blockchain — sending transactions, reading balances, and checking state. One popular Hubble Exchange RPC is https://rpc.hubble.exchange. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says Hubble Exchange already exists when I click Add — what do I do?▾
That's completely normal. If Hubble Exchange is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added Hubble Exchange 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.
