Revoking Approvals Made Earlier in EVM Wallets

Why approvals matter

When you connect your wallet to a dApp, you often grant it permission (an approval) to spend or interact with your tokens. These approvals are stored permanently on-chain until you revoke them.

If left unchecked, scammers can exploit old or unlimited approvals by hacking or abusing the connected smart contracts — potentially draining your funds, even if you no longer use that dApp.

That’s why regularly reviewing and revoking unused approvals is a critical security practice.

Types of approvals

There are generally two categories of approvals in EVM-based wallets:

1. By Contracts – Approvals you granted to specific smart contracts (e.g., DEX, NFT marketplace, lending protocol).
2. By Assets – Token-level approvals allowing dApps to spend a specific token (e.g., USDT, SHPRO, ETH).            Both types can be abused if left active.

The risks of unused approvals

• Hacked dApps or contracts → If a protocol you once trusted is compromised, attackers can use your old approvals.
• Rug pulls & exploits → Malicious developers may design contracts that exploit broad token approvals.
• Forgotten connections → Even if you no longer use a dApp, its approvals may still be active forever.

Revoking approvals reduces your attack surface and protects your wallet.

How to revoke approvals

We recommend using Rabby Wallet for managing and revoking approvals. Rabby provides a clean, user-friendly interface to view all your past approvals across different tokens and contracts.

Steps:

1. Open Rabby Wallet and go to the Approval Management section.
2. Review the list of contract approvals and asset approvals.
3. Identify those you no longer use or trust.
4. Revoke them with one click.
5. Confirm the transaction in your wallet.

Gas & cost considerations

• Revoking costs gas on the chain (ETH gas on Ethereum; BNB gas on BSC; etc.).
• Batching saves money → Most UI tools revoke one approval per transaction, but Rabby Wallet supports batch revokes, letting you revoke multiple approvals in a single transaction. This saves both time and fees.
• Timing matters → If possible, revoke during off-peak hours to pay lower gas.

ShieldGuard Recommendation

• Audit your approvals at least once every 2–3 weeks, or after using new dApps.
• Always revoke approvals for projects you no longer trust or use.
• Use Rabby Wallet’s batch revoke to efficiently clean your wallet in one go.

By staying proactive, you minimize attack risks and ensure your funds remain safe.
