Managing digital assets securely is more important than ever in the fast-evolving Web3 landscape. With increasing interactions across decentralized applications (dApps), users need transparent and comprehensive control over their wallet permissions. To address this critical need, OKX Wallet has introduced a powerful new feature: full historical approval tracking.
This update empowers users with complete visibility into their past smart contract authorizations—giving them greater control, improved security, and peace of mind when navigating the decentralized ecosystem.
👉 Discover how full approval history can protect your crypto assets today.
What Is Wallet Approval?
Wallet approval is a fundamental security mechanism in blockchain transactions. It allows users to grant specific smart contracts limited access to their tokens. For example, if you want to swap 1,000 USDT on a decentralized exchange like Uniswap, you must first approve the Uniswap contract to spend that amount from your wallet.
While approvals enhance operational flexibility—enabling seamless swaps, staking, and yield farming—they also carry risks. Once approved, a malicious or compromised contract could potentially transfer your funds without requiring further permission.
That’s why understanding and managing these permissions is essential for safeguarding your digital assets.
Why Full Approval History Matters
Previously, OKX Wallet only displayed approvals made after the wallet was created or those initiated within the app itself. Historical approvals—especially those made through third-party platforms or early dApp interactions—were not visible, leaving users unaware of lingering authorizations.
With the launch of full historical approval analysis on October 13, 2023 (HKT), OKX Wallet now scans on-chain data to retrieve all past approval transactions associated with your wallet address.
This means:
- You can see every contract you've ever approved.
- You can identify outdated or suspicious authorizations.
- You can revoke unnecessary permissions in one click.
This proactive approach helps prevent potential exploits and reduces the risk of unauthorized asset transfers.
Supported Blockchains
The full approval history feature is currently available across multiple major blockchain networks, including:
- Ethereum
- OKTC
- BNB Chain
- Polygon
- Avalanche C-Chain
- Fantom
- Optimism
- Arbitrum One
- Gnosis
- zkSync Era
Additional chains will be added in the near future, ensuring broader coverage as the multi-chain ecosystem continues to expand.
Security Risks & Best Practices
Despite advancements in wallet technology, phishing and fraud remain persistent threats in the Web3 space. Malicious actors often exploit user trust by deploying fake contracts that request excessive permissions or charge abnormally high gas fees during approval or revocation.
Key Risks to Watch For:
- Phishing Contracts: Fake dApps may mimic legitimate services to trick users into granting approval.
- Infinite Approvals: Some contracts request unlimited token access, which can be dangerous if the project turns malicious.
- Gas Fee Exploits: Hackers may manipulate gas estimates to drain wallets during approval transactions.
Recommended Safety Measures:
- Always verify the authenticity of dApps before approving any contract.
- Use the "Revoke" function regularly to remove unused permissions.
- Check gas fee estimates carefully—abnormally high values may indicate foul play.
- Prefer granting minimum necessary allowances instead of unlimited approvals.

Frequently Asked Questions (FAQ)
Q: Where can I find the approval management tab?
A: Open your OKX Wallet app, go to the homepage, and tap the "Approval" tab. From there, you can view, analyze, and revoke all your historical smart contract approvals.
Q: Why are new approval records appearing after the update?
A: These are not new approvals. The update enables OKX Wallet to detect and display previously invisible historical approvals that occurred before you used the wallet or through external platforms.
Q: Can I revoke multiple approvals at once?
A: Currently, revocations must be done individually. However, OKX is exploring batch-revocation features for future updates to improve user efficiency.
Q: Does viewing approval history cost gas?
A: No. Viewing your approval records is completely free. Gas fees only apply when you initiate a transaction to approve or revoke a contract.
Q: Is my private key exposed when checking approval history?
A: Absolutely not. The analysis is performed off-chain using public blockchain data. Your private keys and seed phrases remain secure and never leave your device.
Q: How often should I review my approval settings?
A: We recommend reviewing your approvals monthly—or immediately after using a new dApp—to minimize exposure to potential risks.
