Feature Breakdown
| Feature | Rating | Details |
|---|---|---|
| Transaction Simulation | 5.0 | Predicts the exact outcome of a transaction (tokens in/out) in <300ms before it hits the chain, effectively ending "blind signing." |
| dApp Scanning | 5.0 | Crawls the web and social media to identify malicious frontends, phishing sites, and "drainers" before users even connect their wallets. |
| Malicious Token Detection | 4.0 | Automatically identifies and hides "scam airdrops" or honeypot tokens that appear in user wallets to prevent accidental interaction. |
| Blockaid Cosigner | 4.0 | An institutional-grade feature that allows multisigs (like Safe) to programmatically block transactions that violate specific safety policies. |
| Risk Monitoring API | 5.0 | A robust API for developers to monitor on-chain assets and infrastructure for anomalies, exploits, or regulatory (OFAC) risks in real-time. |
| Threat Intelligence Feed | 5.0 | A massive data network fueled by integrations with MetaMask and Coinbase, identifying new attack vectors (like Address Poisoning) instantly. |

Frequently Asked Questions
Is Blockaid a wallet I can download?
No. Blockaid is a security infrastructure provider. You don't download a "Blockaid Wallet"; instead, you use wallets like MetaMask, Coinbase Wallet, Rainbow, or World App that have Blockaid’s technology built directly into them to protect you.
Is it free for individual users?
Yes, for the end-user. If your wallet has integrated Blockaid, you get the protection (warnings and simulations) for free. Blockaid charges the wallet providers and exchanges (the businesses) to use their security engine.
How does the "Transaction Simulation" actually work?
When you are about to sign a transaction, Blockaid's engine "dry runs" it on a private version of the blockchain. It looks at the smart contract's code and predicts exactly what will happen (e.g., "You are sending 1 ETH and receiving 0 tokens"). If the result looks like a scam, it triggers a warning before you hit confirm.
Can Blockaid see my private keys or seed phrase?
Absolutely not. Blockaid only sees the metadata of the transaction you are intending to sign (like the destination address and the contract data). It never has access to your private keys or the ability to move your funds.
Does Blockaid catch every single scam?
While Blockaid has a nearly 100% success rate against known "drainers" and common phishing kits, no security tool is perfect. New, "Zero-day" exploits can emerge. You should always treat a Blockaid warning as a "definite no," but a "green light" shouldn't replace your own common sense.
