B3 is a Layer 3 blockchain built mainly for games. It settles on Base, the Ethereum Layer 2 network, so it relies on the security of the layers beneath it instead of running a standalone base chain. The pitch is fast confirmations and sub-cent fees, which suit games that make many small on-chain actions. Because it sits in the Base and Ethereum ecosystem, it is generally treated as EVM-friendly, but check the official docs for exact tooling and wallet support.
The ecosystem's token is B3, which launched on Base in February and is meant to power the network's gaming ecosystem. Fees are described as very low, though the exact gas arrangement can vary by app, and some apps may sponsor fees for players. Token prices move constantly, so look at a live market source for current figures. We list no TVL figure for B3 here because it is primarily a gaming chain and not a DeFi hub.
B3 is known for gaming infrastructure rather than for a set of established DeFi leaders. In April 2026, B3 Labs announced B3OS, a modular toolkit for building on-chain operations, and the project has also discussed PC gaming plans linked to its Base ecosystem. We have no B3 dApps listed on this site at the time of writing, so this page serves as background on the chain until we add reviews.

How to Mine Cryptocurrency on Android in 2026Android phones can run mining software, but their limited processing power, battery drain and heat make profitable mining unlikely. Learn how to assess the risks, try a small proof-of-work experiment safely, and spot apps that only simulate mining or sell cloud contracts.
B3 FAQs
What is B3?
B3 is a gaming-focused Layer 3 blockchain that settles on Base. It aims to give game developers and players fast, very cheap on-chain transactions while building on Base's existing user base and tooling.
Is B3 a Layer 1, Layer 2 or Layer 3?
B3 is described as a Layer 3 that settles on Base, and Base in turn settles on Ethereum. In practice, games and apps run on B3 for speed and low cost, and the results are anchored to the layer below.
How much do transactions on B3 cost?
Project documentation describes fees as sub-cent. Actual costs depend on network conditions and on how a given app handles gas, and some apps may cover fees for users, so check the app itself before you transact.
What is the B3 token used for?
B3 is the ecosystem's native token and was launched on Base in February. It is presented as the token that powers the B3 gaming ecosystem. Its market price changes constantly and has been very low per token, so check a live source rather than relying on this page.
Are there B3 dApps listed on this site?
Not yet. We have no B3 dApps listed at the time of writing, so this page is an overview of the chain. We will add dApps once we have reviewed them.
What is B3OS?
In April 2026, B3 Labs announced B3OS, a toolkit that breaks complex on-chain tasks into modular building blocks. B3 has also talked about PC gaming plans tied to its Base-based ecosystem. Treat these as announcements and read the official docs for current status.
Do I need to be a certain age to use gambling-style games on B3?
Games and apps with betting or wagering features are restricted in many places. You must be 18 or older (21 or older in some regions), and you should confirm that online gambling is legal where you live before using any such app.
