An EVM-compatible blockchain testnet for the Bsquared Network, optimized for low fees and high throughput with native B2 gas and Bitcoin-centric interoperability.
B2 Hub Testnet is the EVM‑compatible test environment for B2 Network’s cross‑chain bridge and routing layer, using B2 as the native gas token. It lets teams safely test cross‑chain asset transfers, liquidity routing, and generalized message passing across supported BTC‑aligned and EVM networks for dApp, wallet, relayer, and validator integrations. As of Sep 2025, no canonical benchmarks for average gas cost, block speed, TPS, or network activity are publicly published; use the project’s testnet explorer linked from bsquared.network to observe live metrics for comparisons.
B2 Hub Testnet is unique for combining a Bitcoin‑aligned cross‑chain bridge with full EVM tooling, enabling end‑to‑end testing of BTC‑aligned liquidity flows and standard ERC‑20 interactions in one unified hub. It mirrors mainnet bridge logic and offers familiar RPCs, faucets, and SDKs, giving deterministic, production‑like cross‑chain testing without mainnet risk. Compared to generic L2 testnets, it prioritizes interoperability over raw throughput; official gas, block‑time, TPS, and activity figures are still being finalized and should be verified via the testnet explorer.
B2 Hub Testnet uses B2 as the gas token for transaction fees. You can obtain B2 by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge B2 to B2 Hub Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select B2 Hub Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on B2 Hub Testnet you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add B2 Hub Testnet to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send B2 on B2 Hub Testnet, ensure your wallet is connected to the B2 Hub Testnet network, enter the recipient's address, specify the amount of B2 to send, review the gas fee, and confirm the transaction in your wallet.
