Transaction Insights: Advanced Web3 Firewall features

Zengo Pro customers also benefit from Transaction Insights, which includes the ability to review transactions before granting final approval. This level of detail is thanks to Transaction Simulations, which help show a best estimation of what you’re approving before you sign an on-chain transaction.

A new paradigm in Web3 security: Web3 Firewall

Zengo’s Web3 Firewall classifies sensitive on-chain transactions into 3 risk levels, based on transaction sensitivity, levels of permission granted to external systems, and known scams. Just like a stoplight, with 3 levels of safety.

Green:

You are interacting with a verified Dapp and/or known smart contract.

Yellow:

This interaction is context-dependent but generally reflects uncommon behavior: Stay alert and confirm that intent is aligned with expected results.

Red:

The Web3 Firewall has detected highly unusual behavior and immediate attention is required. Most of the most sensitive red transactions require a double-confirmation.

Green alerts: Verified dapps

Zengo is integrating leading Web3 Dapps and known smart contracts to confirm when you are connecting to original contracts, and not fake or phishing websites that try and confuse you into giving away your assets. Look for the green checkmark during the signing process.

Verified smart contracts: Zengo has incorporated verified smart contracts on Dapps like OpenSea and Uniswap to provide the clarity and assurance that you are interacting with the legitimate dapps’ smart contracts.*

Yellow alerts: Suspicious approvals & uncommon behaviors

Some transactions are potentially suspicious, others are absolutely fine: Many times it depends on the context of the transaction and your intention. Millions of dollars have been stolen in transactions because it was unclear to the user what they were approving. The Web3 Firewall brings a new level of transparency and clarity to these types of transactions:

Do you intend to send or transfer your crypto or NFTs to a private address, when you thought you were actually engaging with a Web3 dapp smart contract?
If the answer is yes – great: Go ahead. But if the answer is NO: Then the Web3 Firewall alert might just save you from losing millions of dollars
