D3 contributed the following description of d3-doma:

Doma Protocol provides a suite of APIs and smart contracts that enable ICANN Registrars and Registries to tokenize and detokenize domains on the blockchain. When a domain is tokenized, a Domain Ownership Token is minted on the blockchain selected by the Registrant, while Doma blockchain maintains the authoritative record of all tokenized domains. Through signature verification, Doma ensures that domains can only be tokenized only by the hosting Registrar, preventing unauthorized tokenizations.

Zellic conducted a security assessment for D3 from June 2nd to June 11th, 2025. During this engagement, Zellic reviewed d3-doma's code for security vulnerabilities, design issues, and general weaknesses in security posture.
