Improve user security, and verify dapps, smart contracts and their websites, against 17,000+ projects, across dozens of chains.

Use the DappRadar API to verify whether a smart contract or website belongs to a certain dapp. This helps developers to create an environment where users can explore Web3 securely.

Thousands of Smart Contracts and DApps
DappRadar has access to well over 300,000 smart contracts, and that number increases each day. In total more than 17,000 dapps are tracked.

Protect Users Through Contract Verification
Dapps, tools and crypto wallets can use this data to protect users from scams, even before the scam is publicly known. This can help users to protect themselves against phishing attacks, wallet hijacking and other threats. Developers can for example show a prompt, before signing a transaction, to warn users when the smart contract isn’t listed on DappRadar.

Support For 30+ Chains
DappRadar keeps expanding its API services, but currently offers support for more than 30 chains, including the mainnets of Ethereum, Solana, Optimism, Arbitrum, Celo, Polygon, Avalanche, Fantom, Bitcoin, Stacks, NEAR, Flow, Tron, and Binance Smart Chain.
