Sns.sol is a decentralized system on the Solana blockchain that maps human-readable .sol domain names to on-chain data like wallet addresses, IPFS content, images, and text. This makes blockchain interactions simpler and more user-friendly by replacing complex wallet addresses with easy-to-remember names, effectively creating decentralized digital identities.

SNS domains can also link social profiles and host censorship-resistant websites, enhancing privacy and decentralization. Unlike X handles, .sol domains do not require revealing personal information or an X account.
