Any mini app txs get simulated and scanned to ensure they’re not malicious and won’t result in the loss of funds(using Blockaid). This is also why for every tx we show a diff of the assets going in and out of the account

For those not aware, mini app transactions are simulated and scanned using Blockaid to prevent malicious activity resulting in the loss of funds

Hello everyone,

I'm writing to follow up on a recent post I made two days ago regarding what I initially believed to be suspicious transactions in my Farcaster in-app wallet https://farcaster.xyz/sunnyebinum/0xa95f210a At the time, I was concerned that my wallet, along with others, had fallen victim to a crypto drainer. I'm pleased to report that this was not the case, and I'm here to share the crucial insights I gained from this experience.

Here are the key takeaways from this journey:
1. Transparency is Key: When you suspect you've been targeted by a scam or phishing attempt, it's vital to speak up. Your voice can lead to a solution for you and, more importantly, can help prevent others from falling for the same trap.

2. Beware of Zero-Value Attacks: This is a new and subtle trick in the crypto phishing playbook. As explained brilliantly by @linda https://farcaster.xyz/linda/0x3b7c296e these attacks leverage transactions with a zero value to trick you into approving a malicious contract. It's a clever, stealthy tactic designed to fly under the radar.

3. The Power of Wallet Name Services: Alphanumeric wallet addresses are a vulnerability that zero-value attacks can exploit. This risk is significantly mitigated by using wallet name services like ENS. While not a complete antidote, it's a powerful layer of defense.

4. The Farcaster Team is on It: I'm incredibly grateful for the proactive support of the Farcaster team. @linda was quick to respond to my initial post and provided invaluable assistance and a swift resolution. Their commitment to user security is truly commendable.

In light of these lessons, I have a few recommendations for enhancing the Farcaster in-app wallet experience:

1. Filter Zero-Value Transactions: I recommend implementing a feature to automatically filter out all zero-value transactions from the Farcaster wallet. I understand from Linda's response that this is already in the works, which is fantastic news.

2.  Flag Known Threats: It would be a significant security enhancement to label known phishing or scam transactions directly within the in-app wallet's transaction history. This would serve as a clear warning to users.

3.  Integrate Farcaster Profiles with Wallets: Consider a feature that allows Farcaster profile names to double as wallet addresses, enabling users to receive crypto using their profile name. This would not only streamline transactions but also make it more difficult for attackers to spoof addresses. This could be a game-changer for user experience. I'm tagging @linda, @dwr.eth , and @ted  for their consideration.

This experience was a powerful reminder that in the fast-paced world of crypto, every interaction is a learning opportunity. Stay safe out there, fam.
