Digital asset management in the decentralized world demands both security and transparency. One of the most essential yet often overlooked features in crypto wallets is the ability to check and manage token authorizations. With imToken, a leading non-custodial wallet, users gain full visibility into how their ETH and ERC20 tokens are being used across decentralized applications (dApps). This guide walks you through everything you need to know about imToken wallet authorization checks, including what they are, why they matter, and how to use them effectively.
Understanding Token Authorization on Ethereum
Before diving into the functionality within imToken, it's crucial to understand what token authorization means in the context of the Ethereum blockchain.
When you interact with decentralized finance (DeFi) platforms—such as swapping tokens on a decentralized exchange or lending assets—you often need to approve a smart contract to access your tokens. This approval creates an authorization address, which is essentially granting permission for a specific contract to spend a certain amount of your ERC20 tokens.
👉 Discover how secure token management starts with proper authorization control.
While this mechanism enables seamless interactions across dApps, it also introduces potential risks. If a malicious or compromised contract has approval access, it could drain your funds—up to the approved amount—without further consent.
That’s why tools like imToken’s authorization checker are vital for maintaining control over your digital assets.

How imToken Helps You Manage Token Approvals
imToken provides a built-in feature that allows users to view, manage, and revoke token authorizations directly from the wallet interface. This functionality empowers users with transparency and control—two pillars of true digital ownership.
By checking your authorization addresses, you can see exactly which dApps or smart contracts have been granted spending rights on your behalf. More importantly, you can revoke these permissions at any time, closing potential security gaps.
Key Benefits of Using imToken’s Authorization Tool
- Transparency: See all active approvals linked to your wallet.
- Security: Identify suspicious or outdated authorizations.

This level of oversight is especially important if you've used multiple DeFi platforms over time. Many users unknowingly leave old approvals active, creating unnecessary exposure.
Step-by-Step Guide: How to Check Authorization in imToken
Follow these simple steps to audit your current token permissions using imToken:
- Open the imToken App
Ensure you’re logged into your wallet securely. - Navigate to Your Assets Tab
Select the Ethereum network and locate the ERC20 token you want to review (e.g., USDT, DAI, UNI). - Enter the Token Details Page
Tap on the token to open its full information panel. - Find the “Authorized Addresses” Section
Scroll down to locate this option—usually found near transaction history or contract details. - Review Active Approvals
You’ll see a list of smart contracts or dApps that have been granted spending rights, along with the approved amount and date. - Revoke Unnecessary Permissions (Optional)
If you spot an unfamiliar or outdated authorization, tap on it and choose “Revoke” to remove access immediately.
👉 Learn how top users protect their wallets by managing dApp permissions early.
Regularly auditing your approvals—say, once a month—can significantly reduce your risk surface in the DeFi ecosystem.
Frequently Asked Questions (FAQ)
What is a token authorization in imToken?
A token authorization allows a smart contract to spend a specific amount of your ERC20 tokens. It's required when using DeFi services but should be managed carefully to avoid security risks.
Can I revoke a token approval in imToken?
Yes. imToken lets you revoke any existing authorization directly from the token’s detail page under “Authorized Addresses.” This stops the contract from accessing your funds beyond the already-spent amount.
Why should I check my authorization addresses?
Checking helps you detect potentially risky contracts that may have been approved unintentionally or forgotten over time. Revoking unused permissions enhances wallet security.
Does checking authorization cost gas fees?
Revoking an approval requires a blockchain transaction and therefore incurs a gas fee. However, simply viewing your current authorizations is free and doesn’t interact with the network.
Is imToken safe for managing sensitive authorizations?
imToken is a non-custodial wallet, meaning only you control your private keys. As long as you keep your recovery phrase secure and avoid phishing sites, it remains one of the safest options for managing Ethereum-based assets.
Can I see past authorization transactions?
Yes. While imToken shows current active approvals, you can also view historical approval transactions via block explorers like Etherscan by checking your wallet’s transaction history.
Best Practices for Secure Token Management
Beyond just using imToken’s tools, consider adopting these habits:
- Audit Regularly: Schedule monthly reviews of your token approvals.
- Use Revoke Tools: Even if not built into your wallet, external tools can help identify and cancel old authorizations.
- Limit Approval Amounts: When possible, approve only the exact amount needed instead of infinite allowances.
- Stay Informed: Follow trusted sources on emerging scams related to token approvals.
