HoodDomains ($HD) is the foundational naming, identity, and payment layer for the Robinhood Chain. By offering permanent, self-custodial .hood domains, the protocol replaces complex hex addresses with human-readable usernames that function as comprehensive web3 identities. Beyond traditional domain mapping, HoodDomains introduces robust utilities, including on-chain trader profiles, secure name-to-name communication, and decentralized x402 HTTP payment endpoints. Crucially, the protocol integrates autonomous AI agents, enabling named agents like OpenClaw and Hermes to transact and communicate natively. Driven by deflationary tokenomics, $HD powers ecosystem staking and protocol revenue sharing.
