A smart-contract audit can identify serious code defects, but it cannot provide a lasting guarantee of safety once a protocol changes its permissions, upgrades its contracts, or adds dependencies such as price oracles and bridges, according to a security discussion involving Gate and GoPlus Security.
The warning comes as Hacken reported that digital-asset theft reached $1.18 billion across 107 incidents in the third quarter of 2026. The cybersecurity firm said the total was 55% higher than the previous quarter, while roughly 77% of stolen funds were linked to compromises involving tools, vendors, or other components outside the scope of a conventional smart-contract code review.
That pattern places greater weight on continuous monitoring, permission controls, wallet hygiene, and third-party risk checks. A protocol can retain an audit report showing that a particular version of its contracts passed review, yet face a materially different security position after an administrator changes a setting, a multisig signer is compromised, or an external data provider fails.
Audit reports describe a point in time
GoPlus partner Adam said audits should be read as snapshot assessments rather than permanent safety certifications. A report evaluates a defined set of code under a specific scope, usually at a particular deployment stage. It may not cover later upgrades, connected applications, governance processes, or external services that become part of the protocol’s operating model.
Readers reviewing an audit report should first establish exactly what was assessed. Gate’s security team said the document should specify its objectives, limitations, and scope, including whether reviewers examined only a core token or main contract, or also reviewed liquidity pools, strategy contracts, price feeds, bridges, and other dependencies.
A complete report should also show a measurable security rating, a summary of material findings, evidence explaining how each issue could be reproduced, remediation guidance, and confirmation that the fixes were retested, Adam said. A clean report without those details gives users little basis for judging whether the audit covered the risks that now matter.
The distinction becomes more pressing as contracts age. GoPlus said older deployed contracts can be scanned again in bulk as automated security tools improve, sometimes revealing deeper vulnerabilities within minutes. Protocols including Balancer and Yearn have operated for years before researchers uncovered serious flaws, illustrating how a prior review can become stale even where the original auditors performed their work correctly.
Contract code is only one attack surface
The session separated software vulnerabilities from operational abuse involving privileged roles. A contract may be functioning as designed while its owner retains the authority to mint tokens, alter fees, pause transfers, upgrade logic, or move treasury assets. If that authority is poorly controlled, users can suffer losses without an attacker exploiting a coding bug.
Common risks include oversized administrator permissions, leaked private keys, weak multisig approval procedures, insufficient separation of duties, and malicious governance proposals. Audits can identify dangerous access-control designs, but they cannot stop a legitimate operator from using powers that the contract intentionally grants.
External dependencies create another layer of exposure. Price oracles can provide faulty data, bridges can fail or be attacked, and front-end websites can be hijacked to direct users toward malicious approvals. These systems may sit beyond the auditor’s original assignment even though they influence whether users can trade, withdraw, borrow, or redeem assets safely.
Hacken’s third-quarter figures suggest that this boundary is where much recent damage has occurred. The firm attributed the majority of reported stolen value to compromised external tools rather than defects in the primary contracts that users may have relied on. Four major vendor compromises accounted for much of the reported loss, including a $387 million exploit involving Bitget and a $320 million theft involving the Liquid Network, according to Hacken.
Automation changes the balance between attackers and defenders
GoPlus said automated scanning has lowered the time and expertise required to search for known vulnerability patterns. Tasks that previously demanded weeks of manual work from experienced researchers can increasingly be performed in minutes, Adam said.
That does not mean automated tools can independently establish whether a protocol is secure. They can flag suspicious permission structures, common coding patterns, token-transfer restrictions, honeypot behavior, and abnormal tax settings. Interpreting those findings often requires understanding a project’s design and the privileges held by its operators.
The practical effect is that older contracts and lightly maintained projects may face more scrutiny from attackers as scanning becomes cheaper. Defenders must account for a larger range of potential weaknesses, including flaws in code, compromised infrastructure, malicious approvals, and changes to privileged roles.
Gate said it uses listing-stage reviews, periodic security assessments, and on-chain monitoring for upgrades, permission changes, and unusually large transactions. The discussion did not suggest that such monitoring replaces user caution. Exchange custody and self-custody distribute responsibilities differently, but both models leave account-level risks in the hands of the user.
Under self-custody, users must protect their private keys and assess every contract they connect to. With an exchange account, the platform manages the underlying custody infrastructure, while the user remains responsible for passwords, two-factor authentication, phishing attempts, recovery settings, and API permissions.
Practical checks before signing transactions
Users can reduce avoidable exposure by treating every token approval and wallet connection as a security decision. Before interacting with a contract, they should check whether the token has features that could block selling, impose unusual transfer taxes, blacklist addresses, mint additional supply, or give an owner unusually broad powers.
Unused token approvals should be revoked, particularly unlimited allowances that allow a contract to spend tokens from a wallet without further confirmation. Wallet users should verify the domain of an application before connecting, inspect transaction prompts rather than signing them automatically, and use separate wallets for routine applications and long-term holdings.
Hardware-wallet software should be kept current, while API keys should have the narrowest permissions needed and should never permit withdrawals unless that access is essential. Two-factor authentication, passkeys, withdrawal limits, and login alerts provide separate barriers when an account credential is stolen.
Splitting assets across wallets can also contain the damage from a compromised application or vendor. A wallet used to test new decentralized applications should not hold the same balance as long-term cold storage, and a single active account should not become the sole point of failure for an entire portfolio.
Audit reports remain useful evidence, particularly when they are recent, detailed, and matched to the contracts and dependencies a user actually plans to use. Their value falls quickly when users treat them as a substitute for checking permissions, upgrades, approvals, and the third parties connected to a protocol.
