What We Do
Blockaid is the onchain security platform trusted by chains, protocols, wallets, exchanges, banks, and digital asset managers to understand and secure what matters most. Our platform provides unmatched visibility from direct integrations with the most used web3 wallets, plus internet-wide monitoring that detects threats before they reach users. Not only does this give us the most comprehensive coverage of any security provider, but the more pre-transaction, onchain, offchain, and threat intelligence data our system sees, the more our models improve. This flywheel effect has made us the platform of choice for industry leaders like Coinbase, Kraken, MetaMask, Uniswap, World App, and Stellar—as well as traditional institutions and fintechs.
