What is B2 Testnet?

B2 Testnet 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 B2 Testnet once you add the network configuration.

Why do you need to add B2 Testnet to your wallet?

MetaMask and most wallets only come pre-configured with Ethereum Mainnet. To transact, swap tokens, or use dApps on B2 Testnet, 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 B2 Testnet 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 B2 Testnet network.

  2. 2

    Confirm in your wallet

    Your wallet shows the B2 Testnet network details: Chain ID 1123, native token BTC. Verify the Chain ID is correct, then click "Approve" or "Add Network".

  3. 3

  • •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 B2 Testnet 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 Testnet Chain ID?▾
The Chain ID of B2 Testnet is 1123. This unique number identifies the network and prevents MetaMask and other EVM wallets from mixing up transactions across different chains.
Do I need BTC tokens to use B2 Testnet?▾
Yes. Every transaction on B2 Testnet requires BTC to pay gas fees. You can purchase BTC on exchanges and bridge it to B2 Testnet, or use a faucet if this is a testnet.
What is the B2 Testnet RPC endpoint?▾
An RPC endpoint is the server address your wallet uses to communicate with the B2 Testnet blockchain — sending transactions, reading balances, and checking state. One popular B2 Testnet RPC is https://b2-testnet.alt.technology. This page shows live latency for each RPC so you can pick the fastest one.
My wallet says B2 Testnet already exists when I click Add — what do I do?▾
That's completely normal. If B2 Testnet is already in your wallet, it will simply switch to that network instead of adding a duplicate — no error or conflict.
I added B2 Testnet 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.
