🛡 Crypto Security: Token Approvals
Protect your assets by managing contract permissions
🎯 What Are Token Approvals?
When you use a DEX, staking platform, or any dApp, you approve the smart contract to spend your tokens. These approvals can be unlimited and remain active even after you're done — creating a security risk if the contract is compromised.
⚠️ Why This Matters
- 🔒 Unlimited approvals give contracts permanent access to your tokens
- 💣 Exploited contracts can drain approved tokens even months later
- 🌎 Phishing sites trick users into approving malicious contracts
- 💰 Your tokens are at risk until you revoke the approval
