I would love to see what the team at OP Labs 
could do with this type of technology…
We have just implemented this as one of our new partners to increase security for our community and would love to see Optimism bring on new partners like this to help with the sybil attackers.
User Wallet Fraud Detection
This API flags wallets with irregular patterns that are common among malicious actors. Banks have developed the ability to identify patterns of transactions that allow them to freeze accounts complicit in money laundering. SHIELD analyzes blockchain transaction history to develop its own fraud detection models.
SHIELD gives access to input variables useful for predicting scams before they happen. Some variables include:
| Fraudulent Behavior | Money Laundering |
|---|
Wallets with abnormal/rapid movement of funds in a short time frame or interacted with a known exploit
Wallets sending amounts to an alternative wallet which then sends the same amount an exchange
Wallets has created unverified smart contracts
User Tornado Cash Compliance
Monitor your user base for malicious or irregular transaction history
This library detects wallets that have interacted with sanctioned protocols such as Tornado Cash. We also scan for “burner wallets” used to obfuscate illegitimate transfers and a growing range of indicators for malicious actors.
The U.S. Treasury Department’s Office of Foreign Assets Control sanctioned Tornado Cash on August 8th, 2022.
Transaction Verification and Simulation
Simulate expected outcome of any blockchain transaction
Shield also serves as a robust data provider for bad actor reputational data and enables protocols and infra projects to identify patterns of users that engage in malicious activity.
