According to @MonkeDAO, traders can qualify for a free monkedao.sol subdomain by holding a Gen2 or Gen3 MonkeDAO NFT, verifying ownership in the SNS Discord through @MatricaLabs, and ensuring the subdomain is linked to the same wallet (source: @MonkeDAO Twitter, June 2024). The subdomains are currently free, providing immediate utility for NFT holders and increasing engagement with the Solana ecosystem, a key factor for those trading or speculating on Solana-based NFT projects.
