Industry Security Mega Test, Self-Custody Wallet is the Future of Web3

Source: OKX

The algorithmic wave never stops, and a security incident is like the sword of Damocles hanging over one's head, not a matter of "if" but "when." Recently, both CEX and DeFi have frequently fallen victim to hacker attacks, with asset losses, contract vulnerabilities, and trojan viruses casting shadows over the market, once again making "security" a focus. The crypto world has never been absolutely secure, only with constantly evolving security strategies. As the traditional financial "too big to fail" rule fails in the Web3 world, the industry faces an unprecedented question: Whom should we entrust our asset security to?

OKX clearly recognizes the security risks in the crypto industry, but we focus on solutions rather than fear—fear does not solve problems; technological innovation is the answer. We care about the security of all crypto users, no matter where everyone trades. We always advocate for higher security standards and, through technologies such as self-custody wallets and POR, empower users to truly own their asset sovereignty. This is not marketing but rather the inevitable direction of industry development.

We believe that the future of Web3 is not built on centralized trust platforms but on code, transparency, and user sovereignty. True security does not rely on a single platform but is controlled by the users themselves. Therefore, the self-custody wallets we advocate for are not just a product concept but a paradigm shift in the industry, representing a return to trustlessness, transparency, and individual sovereignty. OKX is committed to promoting higher security standards, not only for itself but also for the entire industry, to provide more transparent and trustworthy solutions.

We hope to strengthen OKX's commitment to crypto security by helping users understand the concept of self-custody wallets, assisting users in making informed decisions, and raising awareness of security. OKX firmly believes that the industry must continue to evolve to protect user asset security. We support stricter security standards to ensure the long-term development of the entire industry.

The essential difference between "platform security" in the traditional paradigm and "self-sovereign security" in the Web3 era is significant. "Not your key, not your money"—self-custody wallets give users absolute control over their crypto assets, enabling decentralized management through unique private keys. Users can complete asset storage, transactions, and other operations without relying on third-party institutions, truly becoming managers of their personal digital assets. This security mechanism based on mathematical proof completely breaks free from the traditional security framework reliant on human operations, safeguarding not only the integrity of asset ownership and privacy but also avoiding redemption risks due to centralization platform crises. However, absolute control comes with full responsibility, as users must independently uphold security obligations like safeguarding mnemonic phrases.

When it comes to account generation and private key backup, unlike traditional wallets that only support deriving multiple wallets from one set of mnemonics, the OKX Web3 Wallet is the only wallet that can create multiple sets of mnemonic wallets and derive multiple accounts from one set of mnemonics. This enhances user flexibility and security in asset management, effectively reduces the risk of private key exposure. In addition, the OKX Web3 Wallet has revamped the backup process, allowing users to simply log in to their iCloud/Google account and set an encryption password to complete an off-chain backup. This solution breaks free from traditional hardware dependencies, enabling quick asset recovery through cloud-verified encrypted backups even in cases of device loss or forgotten mnemonics. The triple protection system—cloud storage + password verification + local encryption—not only lowers the operational threshold but also establishes a single-point-of-failure-resistant insurance mechanism for encrypted assets.

Simultaneously, the OKX Web3 Wallet offers robust private key protection features such as prohibiting users from taking screenshots or screen recordings of private keys and mnemonics to prevent information leaks. To further enhance security, it also supports functions like segmented private key copying to ensure protection at every step. Through these protective measures, users' private keys and mnemonics are always kept under strict security measures, reducing potential security risks.

According to a public audit by SlowMist Technology, all private keys and mnemonics of OKX Web3 Wallet users are stored only on their local devices and are not uploaded to any external servers. Furthermore, the OKX Web3 Wallet's related SDK is open-source, having undergone extensive validation and continuous review by the global developer community, ensuring greater transparency. The OKX Web3 Wallet's private key security module complies with financial-grade security standards, ensuring mnemonic offline storage throughout without ever touching the internet.

To address the prevalent "infinite allowance" risk in the DeFi ecosystem, the OKX Web3 Wallet features built-in smart contract permission management functions, supporting custom authorization limits, one-click revocation of risky authorizations, continuous risk monitoring, 30-day inactive DApp risk alerts, regular pop-up warnings of risks, and other highlight features. This further eradicates asset exposure risks caused by over-permissions, establishing a "least privilege" security paradigm.

For instance, many users have previously authorized various contracts, but contracts that have remained inactive for an extended period may become targets for hacker attacks due to lack of maintenance by project teams. The OKX Web3 Wallet records user-authorized contracts via on-chain retrieval functionality and tracks and manages risk-free contracts. For long-inactive contracts, the system automatically detects them and promptly alerts users upon identifying risks. Every 30 days, the system sends a reminder to users who have not revoked authorizations for long-inactive contracts, advising them to regularly manage wallet contract authorizations, cancel unused contracts promptly to reduce potential risks. Moreover, the OKX Contract Monitoring Engine provides 24/7 security protection, continuously scanning user-authorized contracts and promptly notifying users to revoke authorizations upon identifying risks; if authorizations are not canceled within 24 hours, the system will issue another pop-up reminder.

Regarding on-chain interaction risk, the OKX Web3 Wallet provides powerful risk transaction identification capabilities, such as integrating the Eye of God KYT system to build an active defense network, real-time scanning of a risk address label library. At key points such as DApp interaction, asset transfer, etc., through machine learning to dynamically identify threats such as malicious contracts, phishing addresses, it achieves millisecond-level risk prevention before transactions. This protection system deeply integrates user autonomy with professional risk control capabilities, allowing self-custodial wallets to maintain decentralized characteristics while obtaining security capabilities that surpass centralized platforms.

The future of the industry is still unknown, but self-custodial wallets are undoubtedly a deterministic path—becoming the "Noah's Ark" of user asset security.
