Caldera, a blockchain-based ecosystem, has launched a free domain registration service allowing users to mint unique ".era" usernames. Each user can claim one distinct identity across the Metalayer, facilitating connection and exploration within the Caldera environment. The minting process requires connecting a wallet, signing in, and selecting a preferred name. Notably, the minting is gas-free, enhancing accessibility. Caldera recently secured $24 million in funding, led by Dragonfly, highlighting investor confidence in the project. Users are encouraged to claim their usernames promptly to ensure availability.
