# Blockaid

> Blockaid is a web3 security platform that detects and responds to scams, fraud, financial risk, and smart-contract exploits in real time. Its API scans transactions, addresses, tokens, dApp sites, and messages across EVM chains, Solana, Bitcoin, Stellar, Sui, Starknet, Tron, and Hedera, returning a risk verdict that wallets, exchanges, and marketplaces (MetaMask, Coinbase, Uniswap, OpenSea) use to block malicious activity before it happens.
