According to @sns, the .sol subdomain registrar is now live and open for registrations, enabling users to claim subdomains under existing .sol names, source: @sns on X, x.com/sns/status/1987809145819406538. On Solana, each registration and update is an on-chain transaction that requires SOL to pay network fees, source: Solana Documentation, docs.solana.com/transaction_fees. Solana destroys 50% of all transaction fees by protocol design, so registrar usage directly contributes to incremental SOL fee burn, source: Solana Documentation, docs.solana.com/transaction_fees. The Solana Name Service supports hierarchical subdomains that map human-readable .sol names to on-chain addresses used across wallets and dApps, providing scalable identity and routing for users and brands, source: Solana Name Service Docs, docs.bonfida.org/solana-name-service/sns-sol-domains/subdomains. As registrations and updates occur, this registrar becomes a new on-chain activity vector tied to SOL fee payments and burns, which traders can track to assess short-term demand within the Solana ecosystem, source: @sns on X, x.com/sns/status/1987809145819406538 and Solana Documentation, docs.solana.com/transaction_fees.
