Frequently asked questions

Is it safe to add B2 Hub 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 B2 Hub Mainnet Chain ID?▾
The Chain ID of B2 Hub Mainnet is 213. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need B2 tokens to use B2 Hub Mainnet?▾
Yes. Every transaction on B2 Hub Mainnet requires B2 to pay gas fees. You can purchase B2 on exchanges and bridge it to B2 Hub Mainnet, or use a faucet if this is a testnet.
What is the B2 Hub Mainnet RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the B2 Hub Mainnet blockchain — sending transactions, reading balances, and checking state. One popular B2 Hub Mainnet RPC is https://hub-rpc.bsquared.network. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says B2 Hub Mainnet already exists when I click Add — what do I do?▾
That's completely normal. If B2 Hub Mainnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added B2 Hub 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.
