B3

• B3 is a gaming-focused Layer 3 network built on Base, itself an Ethereum Layer 2.

• It lets games run dedicated chains while sharing infrastructure and liquidity.

• B3 is the network token.

• Supply allocated across community, ecosystem and contributors.

• Used for network fees and ecosystem incentives.

Pros:

• Dedicated per-game chains avoid congestion from unrelated activity.

• Base ecosystem provides a distribution channel through Coinbase.

• Lower fees than Layer 2 for high-frequency game transactions.

Cons:

• Layer 3 adds another dependency layer, inheriting risk from both Base and Ethereum.

• Blockchain gaming retention is weak regardless of infrastructure.

• Requires studios to adopt the framework.

• Exposure to gaming infrastructure within the Base ecosystem.

• Per-game chains address a real congestion problem.

• Weigh the stacked dependency and the sector's retention record.

• Per-game chains on Base, so a busy game does not compete with unrelated applications for blockspace.

• Games generate high transaction volumes that congest shared chains and raise costs for everyone.

• Dedicated chains isolate that load while retaining shared liquidity.

• Developed by NPC Labs, founded by former Coinbase employees including chief executive Daryl Xu.

• NPC Labs raised $21 million in a round led by Pantera Capital, with Makers Fund, Hashed and Sfermion among other investors.

• No public ICO. B3 launched in February 2025 with a Season 1 airdrop to early players and builders, with further community distribution planned.

• Stacked dependency on both Base and Ethereum.

• Blockchain gaming retention is weak sector-wide.

• Studio adoption is required and uncertain.

• Competition from other gaming-focused chains.
