🔐 Before You Sign: Understand What Your Wallet Is Asking
In Web3, your wallet signature is the final authorization before an action happens. Understanding what you’re signing is critical to protecting your assets.
✍️ Two Types of Wallet Signatures:
1️⃣ Transaction Signing (On-Chain)
This executes an action on the blockchain, such as sending cryptoSwapping tokensInteracting with smart contracts
Once confirmed, the transaction is irreversible.
2️⃣ Message Signing (Off-Chain)
This usually doesn’t move funds immediately, but it can grant permissions to smart contracts. Malicious DApps may request signatures like Permit or Permit2, which can allow attackers to access or move your tokens later.
⚠️ Stay Alert
If a signature request seems unrelated to the action you're performing, do not sign it. Always pause and review before approving any request.
Your signature is the key to your wallet. Use it with extreme caution.
