What is the Random Ethereum Address Generator?
An Ethereum address is a 20-byte identifier written as 0x followed by 40 hexadecimal characters, such as 0xf80fc399f45a2ca16a5266ece9d28db7a48432ea. Wallets, smart contracts, block explorers and dApps all need to accept, display and validate these values, which means developers need plenty of realistic samples to test with.
This generator creates random addresses in exactly that format, up to 100 per batch, using the Web Crypto API in your browser. The addresses are output in lowercase, which is a valid representation; they do not include the mixed-case EIP-55 checksum, so use them where plain hex addresses are accepted or apply a checksum with your own library.
Crucially, these addresses are not generated from a private key. Nobody holds the keys to them, so any funds sent to one would most likely be lost forever. Use them only for UI testing, form validation, placeholder data and documentation — never as a destination for real transactions.
How to use the Random Ethereum Address Generator
- Enter How many? addresses you need, up to 100.
- Press Generate to create random 0x addresses.
- Copy a single address or the full list.
- Export the addresses as CSV, JSON or TXT for your tests.
Popular uses
- dApp developers — test address inputs, display truncation and validation.
- QA testers — fill wallet and payout forms with correctly formatted values.
- Designers — show realistic addresses in wallet and explorer mockups.
- Technical writers — use neutral example addresses in docs and tutorials.
Why use RandNow?
- Instant & unlimited — no sign-up, no daily caps.
- Private by design — results are generated in your browser, not on our servers.
- Export-ready — copy, CSV, JSON and TXT downloads built in.
- Cryptographically random — powered by the Web Crypto API.
Testing only — never send funds
A random address is valid in format, but nobody controls it. Transactions on Ethereum cannot be reversed, so sending real ETH or tokens to a generated address means losing them. Use test networks and your own test wallets when you need to move funds, and never use generated data to mislead or defraud anyone.
About checksummed addresses
EIP-55 encodes a checksum in the capitalization of the letters, helping wallets catch typos. Most libraries can convert a lowercase address to its checksummed form. Press Generate again for a fresh set — it’s free and unlimited.
Frequently asked questions
Are these real Ethereum addresses?
They have a valid format, but they are random and not derived from any private key, so no one controls them. Never send funds to them.
Why are the addresses all lowercase?
Lowercase is a valid hex form of an address. The mixed-case EIP-55 checksum is not applied; your Web3 library can add it if needed.
Can I use these addresses on a test network?
You can use them as recipients in tests, but since no one holds their keys, any test tokens sent to them cannot be recovered.
How many addresses can I generate at once?
Up to 100 per batch.
