Random Ethereum address generator
Generate a random Ethereum private key and its matching public address in your browser. Copy the values individually for development and testing.
Generate a key pair
Keep your private key secret: anyone with it can control the address. Generating again replaces the displayed pair.
Keys are generated locally using secure browser randomness. This tool does not send or save them. Copying places the selected value on your clipboard.
Key and address formats
The private key is 32 bytes shown as hexadecimal with a 0x prefix. The public address uses Ethereum’s EIP-55 mixed-case checksum.
Generating an address does not fund it or submit a transaction.
Use generated addresses in development workflows
A sample Ethereum key pair can help you test address fields and wallet-related interfaces. A private key controls its matching account, so never paste a real funded wallet’s private key into a test fixture or public example.
