The policy states that OpenSea makes blockchain activity data, including purchases, sales, and transfers, available to external websites and applications via API as part of service delivery.

This provision authorizes disclosure of blockchain transaction data to third-party websites and applications beyond the OpenSea platform. The legal basis asserted is contract performance, which may require evaluation under GDPR purpose limitation and data minimization principles depending on the scope and nature of data exposed.
Interpretive note: The scope of data categories exposed via API and the identity or categories of API recipients are not specified in the policy, creating uncertainty about the full extent of disclosure.
Under this clause, blockchain activity data associated with a user's wallet address and OpenSea activity may be accessed by third-party developers and applications through OpenSea's API. The agreement does not specify the categories of third parties that may access this data or the controls applied to their use of it.

"In order to provide our Services in accordance with our contract with you, we may display or share information relating to your public activity on blockchains, OpenSea, and/or OpenSea Pro. For example, we use technology like APIs to make certain information like your blockchain activity available to websites, apps, and others for their use.Excerpt from OpenSea's Privacy Policy
(1) REGULATORY LANDSCAPE: This provision may require evaluation under GDPR purpose limitation (Article 5) and data minimization principles, as API-based disclosure to unspecified third parties on the basis of contract performance may be a broader basis than GDPR anticipates for secondary data use. The relevant enforcement authorities are EU data protection authorities and the UK ICO. (2) GOVERNANCE EXPOSURE: Medium. The provision asserts contract performance as the legal basis for broad API-based data disclosure to external parties, which may face scrutiny under GDPR if the scope of data disclosed or the identity of recipients is not sufficiently defined or communicated to users. (3) JURISDICTION FLAGS: EEA and UK users have heightened exposure given GDPR requirements for transparency about recipients and legal bases for processing. California users under CCPA are entitled to disclosure of categories of third parties with whom personal information is shared. (4) CONTRACT AND VENDOR IMPLICATIONS: Third-party developers and applications accessing the API should assess their own data processing obligations upon receipt of user blockchain activity data. OpenSea's policy does not explicitly address contractual restrictions imposed on API recipients. (5) COMPLIANCE CONSIDERATIONS: Compliance teams should assess whether the API disclosure is adequately scoped in user-facing notices, whether recipients are subject to data processing agreements, and whether the contract performance basis is appropriately applied under GDPR given the breadth of potential disclosures.
