Why it matters

Multisig transactions can be opaque. Safe Shield cuts through that by showing:

• Security signals from trusted providers (e.g., Blockaid, Tenderly, Hypernative).

• Context on recipients/contracts (new interactions, address book status, activity).

• Outcome checks via pre-execution simulation when available.

How it works

When you prepare a transaction, Safe Shield runs a pre-transaction analysis and displays results inline. Each item carries a clear severity:

Key features

Recipient & Contract Checks

• Flags first-time and recurring interactions.

• Shows whether the address appears in your Safe{Wallet} address book (local and shared address book, if any)

• Highlights verified vs. unverified contracts based on data from Etherscan, Sourcify and Blockscout.

• Surfaces unusual patterns (e.g., destination with very limited history).

Threat & Risk Checks

Threat and risk checks identify potential security issues or suspicious patterns before you approve a transaction.

• Surfaces malicious or suspicious activity detected by trusted providers (e.g., Blockaid, Tenderly).

• Highlights moderate risks or unusual transaction behavior for review.

• Warns about critical contract or ownership changes, like mastercopy or module updates.

• Provides clear severity levels — Accept, Warn, or Deny — so you can decide whether to proceed safely.

• Helps protect against phishing, drainer contracts, and unsafe configuration changes.

Safe Configuration Checks

Safe configuration checks help ensure your transaction doesn’t break compatibility or alter your Safe setup unexpectedly.

• Detects incompatible Safe versions before execution.

• Warns when ownership is missing or mismatched on the target Safe.

• Flags if the target network isn’t supported in Safe{Wallet}.

• Alerts when Safe setups differ (e.g., owners, modules, or thresholds).

• Encourages manual review when configuration mismatches are found — helping prevent access loss or setup conflicts.

Guard Configuration Checks

Guard checks confirm whether your Safe’s built-in protection layer is active and functioning as intended.

• Shows if a Guard is installed and actively monitoring transactions.

• Warns if no Guard is configured, so you’re aware of reduced protection.

• Flags Guard configuration errors that may stop rules from applying correctly.

• Helps ensure your Safe operates under the intended security policies

Transparency & limits

Safe Shield depends on third-party data and internal services. If a provider is down or a check times out, you’ll see an explicit notice so you can decide how to proceed. No tool can guarantee absolute safety; Safe Shield makes the risks and context obvious before you sign.
