Opensea Seaport codebase lineage and protocol family
Opensea Seaport is published as a versioned release inside the Opensea protocol family. Releases inside the same family typically share governance, brand, and large parts of the audit history, but each version can run materially different contract logic — a release labelled v2 or v3 is not just a UI refresh. Newer versions inside a family typically launch with their own audit cycle and parameter set, so do not assume the previous release's safety record carries over without checking the linked audit reports.
Fork lineage and parent-protocol relationships are tracked by DeFiLlama for security and audit-history attribution; a fork inherits the upstream design but not necessarily the upstream audits or governance.
Security & Audits
OpenSea engaged Trail of Bits to audit the security of Seaport. From April 18th to May 12th 2022, a team of Trail of Bits consultants conducted a security review of Seaport. The audit did not uncover significant flaws that could result in the compromise of a smart contract, loss of funds, or unexpected behavior in the target system. Their full report is available here.
