Base launched Basenames on August 20, 2024, allowing users to claim unique base.eth usernames, simplifying onchain interactions, collaborations, and contributions.

What are Basenames?
Basenames are essential onchain identifiers that enable users to establish their identity on Base by registering human-readable names linked to their wallet address(es). Built entirely onchain, they leverage the same technology as ENS names and are deployed on Base. These names can be used when connecting to onchain apps, sending, and receiving transactions on Base, and across other EVM chains.

How to Get a Free or Discounted Basename?
You can obtain one free Basename (with 5 or more letters) for one year if you meet any of the following criteria:

• Coinbase Verification
• Coinbase One Verification (free renewals with an active subscription)
• Summer Pass Level 3 NFT
• Buildathon participant NFT
• base.eth NFT holder
• cb.id username (acquired before Friday, August 9, 2024)
• BNS name owner - free 4+ letter name (basename.app)

Your Basename can be used across apps in the Base ecosystem, starting with base.org, Onchain Registry, and Onchain Summer Pass. Additionally, it can be utilized for sending and receiving transactions on Base and other EVM chains.
