SEO-friendly FAQs about Ethereum (ETH) wallet generation, private keys, seed phrases, and bulk wallet generation.
How do I generate an Ethereum (ETH) wallet?
Use the Single Generator to create a new Ethereum wallet locally in your browser. You’ll get an address, private key, public key, and a 12-word recovery seed phrase.
Is this a real Ethereum wallet generator?
Yes. This tool uses a real Ethereum wallet derivation (secp256k1 keys and the correct address derivation). Treat all generated secrets as highly sensitive.
Are Ethereum wallets generated offline?
Wallets are generated locally in your browser using CSPRNG. For true offline generation, run this page on a machine that is not connected to the internet.
What is a 12-word seed phrase (recovery phrase)?
A seed phrase is a human-readable backup that can recreate your wallet. Anyone with your seed phrase can control your funds.
What is the private key and why must it be secret?
The private key authorizes spending. If someone gets your private key (or seed phrase), they can move your ETH and tokens.
Can I generate multiple Ethereum wallets in bulk?
Yes. The Bulk Generator creates multiple wallets in one batch. Bulk generation is useful for testing and operations, but increases the risk of accidental exposure—store results securely.
Does exporting JSON include private keys and seed phrases?
Yes. Export JSON includes wallet secrets. Treat exported files as highly sensitive and store them encrypted if possible.
How do I verify an Ethereum address is valid?
A typical Ethereum address starts with 0x and has 40 hex characters. For strongest verification, import the seed into a trusted wallet and confirm the derived address matches.
What are common mistakes when generating wallets?
Generating on a compromised machine, storing seeds in cloud notes, pasting seeds into chats/emails, and leaving seed logs readable on a public server.
Can I use this for cold storage?
Yes. Generate offline, record the seed securely (paper/metal), and never expose it to an online device. Test recovery before funding.
Does this work for ERC-20 tokens too?
Yes. Tokens live at your Ethereum address. If you control the private key/seed for an address, you control ETH and tokens at that address.
Why is an air-gapped machine recommended?
Air-gapping reduces malware and exfiltration risks. For real funds, offline generation and secure storage are best practice.
