The post titled “Security Audit Report: Reentrancy & Access Control Review: Gemini” exists, but its claims about a Gemini smart-contract audit are not corroborated by Gemini’s public materials reviewed here. Those materials describe an exchange and custodian, account security, API permissions, and corporate cybersecurity—not a matching Solidity codebase or contract-level audit. Treat the post’s Gemini-specific findings as unverified, not as an established audit report.
Is there a verified Gemini smart-contract audit report?
A DEV Community post by DannyDoes, published September 28, 2026, uses the matching title and names several purported Gemini contracts. But Gemini’s official materials reviewed here do not confirm those contracts, an audit engagement, or the post’s claimed findings. No primary audit report or verifiable contract scope was established. The post’s vulnerability totals, severity ratings, code version, dates, TVL, and impact claims therefore should not be treated as verified facts.
Gemini’s Trust Center lists corporate financial audits and SOC 1 and SOC 2 Type 2 examination periods. These are not evidence of a Solidity contract audit. Likewise, Gemini’s general smart-contract-audit explainer describes the audit process; it is not a report on Gemini contracts.
What reentrancy means—and what evidence would establish it
Reentrancy is a smart-contract control-flow risk. When a contract makes an external call, it may hand control to another contract that can call back into the original before the first operation has finished. If state or accounting remains stale during that callback, an operation may be repeated in an unsafe way.
#1 Best Overall
Ethereum.org’s smart-contract security guidance describes the checks-effects-interactions pattern: check conditions, update contract state, then interact externally. This can reduce the opportunity for a callback to repeat an action against stale state. It is general guidance, not a finding about Gemini.
To substantiate a reentrancy finding in a particular contract, a report should identify the code and execution path: the external interaction, how a callback can occur, which state or invariant is affected, and why the impact is realistically exploitable. No Gemini contract source or primary report confirming such a path was established here.
What “access control” means for a contract versus a Gemini account
In a smart-contract review, access control concerns who can invoke protected operations and how the contract enforces that authorization. A credible finding should name the operation, show the relevant check—or its absence—and explain privileged actors and deployment or configuration assumptions. Gemini’s API-key roles are a separate system: they govern permitted operations through Gemini’s exchange APIs, not Solidity ownership or contract modifiers.
Gemini API-key roles
Gemini’s developer documentation describes these roles and capabilities:

| Trader | Trading-related operations. |
| Fund Manager | Trading-related operations plus withdrawals and internal transfers. |
| Auditor | Read-only access. |
| Administrator | Administration of accounts in a master group; available only for Master API keys. |
These permissions help distinguish API access levels. They do not establish how any purported Gemini smart contract authorizes calls. For operational use, check Gemini’s live documentation for the current requirements of each endpoint.
What Gemini says about account and corporate security
Gemini’s security page says that two-factor authentication is required by default to access an account and make withdrawals. It also describes hardware security keys such as YubiKey as an option for a more secure 2FA experience, and withdrawal address allowlisting. Gemini further cites third-party security assessments, including SOC 2 Type 2, ISO 27001, and annual penetration testing. These are Gemini’s published descriptions of account and organizational controls, not proof that a particular smart-contract implementation is safe.
Those account protections address access to a Gemini account and withdrawal controls. They do not fix faulty contract logic or establish whether a smart contract has a reentrancy or authorization flaw.
Gemini’s 2025 Form 10-K describes a cybersecurity risk-management program integrated into enterprise risk management and aligned with the NIST Cybersecurity Framework and other applicable frameworks. It outlines a three-lines model, board and audit-and-risk committee oversight, and security leadership. The filing says Gemini had not identified known cybersecurity threats or incidents that materially affected, or were likely to materially affect, the company as of the report date. That is a dated company disclosure, not a guarantee of future security or evidence about the unverified contract claims. Read the filing.

How to assess a claimed smart-contract audit
Before relying on a report that names an exchange or protocol, check whether it provides enough information to connect its conclusions to real code and deployments:
- Auditor and report: Is the auditor named, and is the complete report available from a verifiable source?
- Code identity: Does the report specify the exact repository, commit or version, and deployed contract addresses it reviewed?
- Scope and exclusions: Does it say which contracts and components were included, and what was excluded?
- Finding evidence: For each issue, does it show the affected code, relevant execution path, assumptions, and reasoned severity?
- Remediation and retest: Does it document whether the issue was fixed and whether the changed code was checked again?
Gemini’s educational overview describes common audit work such as manual analysis, architecture documentation, bug identification, and testing. A title, a list of contract names, or an impact assertion alone cannot establish that those steps were performed or that a finding is reproducible.
