Real-time transaction simulation that flags risks before funds move

Blockfence simulates every transaction in a sandboxed environment before it executes on-chain. This allows the tool to detect malicious contract behavior — such as hidden approvals or token drains — without exposing real funds. The simulation runs within seconds, making it practical for everyday trading.

Business outcome: Reduces the likelihood of approving malicious transactions by catching scams at the simulation stage.

Phishing and scam detection across websites and dApps

The browser extension continuously scans websites and decentralized applications for known phishing signatures and impersonation patterns. When a user lands on a suspicious site — such as a fake Uniswap clone — Blockfence displays a prominent warning before any interaction occurs.

Business outcome: Minimizes exposure to phishing attacks that target crypto credentials and seed phrases.

Developer API for embedding security checks into any Web3 product

Blockfence offers a RESTful API that allows developers to integrate transaction scanning and threat detection directly into wallets, DeFi platforms, or NFT marketplaces. The API returns risk scores, contract analysis, and known scam signatures in real time.

Business outcome: Enables Web3 platforms to offer built-in security features without building detection infrastructure from scratch.

Threat intelligence dashboard with real-time scam tracking

The dashboard aggregates data from Blockfence’s scanning network, showing trending scams, flagged addresses, and threat severity levels. Teams can use this data to adjust security policies or alert their user base about emerging risks.

Business outcome: Provides actionable intelligence that helps security teams stay ahead of evolving scam tactics.

Multi-wallet support including MetaMask, WalletConnect, and Coinbase Wallet

Blockfence integrates directly with popular browser wallets, intercepting transaction requests before they are signed. This means users get risk assessments regardless of which wallet they use, creating a unified security layer across different platforms.

Business outcome: Ensures consistent protection across multiple wallets and chains, reducing fragmentation in security coverage.

Multi-chain support for Ethereum, BSC, Polygon, and more

The tool scans transactions across major EVM-compatible blockchains, including Ethereum, Binance Smart Chain, Polygon, Avalanche, and Arbitrum. This multi-chain coverage is essential for teams operating across different ecosystems.

Business outcome: Protects assets across the most active blockchain networks, not just a single chain.

• Phishing site detectionIdentifies fake dApps and phishing pages before users interact with them, reducing credential theft.
• Developer-friendly APIRESTful API makes it straightforward to embed security checks into existing Web3 products.
• Multi-chain coverageSupports Ethereum, BSC, Polygon, and other EVM chains, making it useful for cross-chain teams.

• Limited to EVM chainsDoes not support non-EVM chains like Solana or Bitcoin, limiting its use for multi-chain teams.
• No hardware wallet integrationCannot protect against private key theft or physical security breaches.
• Free plan is basicThe free tier only covers one wallet and lacks advanced threat intelligence features.
• Professional RealityBlockfence is a strong first layer of defense for transaction-level scams, but teams handling large treasuries should combine it with cold storage and multi-sig wallets.

Individual crypto traders managing active portfolios

A trader executing multiple swaps per day can use Blockfence to scan each transaction before signing. The tool catches hidden approvals and malicious contract interactions that could drain the wallet.

DeFi development teams building secure dApps

Developers integrating Blockfence’s API can offer their users real-time transaction risk scores directly within the dApp interface, reducing support tickets related to scams.

Crypto treasury teams managing DAO funds

DAO treasuries handling large token holdings can use Blockfence to pre-screen all outgoing transactions, ensuring no malicious contract is approved during governance operations.

Security researchers tracking emerging scams

Researchers can use Blockfence’s threat intelligence dashboard to monitor trending scam addresses and analyze new phishing patterns across multiple chains.
