Bitcoin, Ethereum, Tron & Solana wallets — made in your browser
Generate a seed phrase, derive an address from any seed or private key, mine a vanity address, and check balances. Every key is created locally with audited cryptography — nothing is uploaded.
- Keys generated in your browser
- Nothing uploaded — no trackers
- Audited noble/scure crypto
A browser is a hot environment. For real funds, generate keys offline or use a hardware wallet, and never paste a seed phrase that holds money into any website — including this one.
How it works
A wallet generator that never sees your keys
Many online generators create your key on their server — meaning they could keep it. This one runs the same audited cryptography (the @noble / @scure libraries) directly in your browser. The page works offline once loaded; only the optional balance check talks to the network, and it only ever sends a public address.
FAQ
Common questions
Is the wallet generated on a server?
No. Seed phrases, private keys and addresses are generated entirely in your browser with audited noble/scure cryptography. Nothing is uploaded. Balance checks are the only network requests and they only send your public address.
Which chains and address types are supported?
Bitcoin (native SegWit bc1… and legacy 1…), Ethereum (EIP-55), Tron and Solana. One seed derives a default account on each using standard BIP44 / SLIP-0010 paths.
How does a vanity address work?
Web Workers generate random keypairs until the address matches your chosen start or end characters. Each extra character is roughly 16× harder (hex) or 58× harder (Base58), so short patterns finish quickly and long ones can take a very long time.
Can I use these for real money?
For learning, testing and vanity experiments, yes. For meaningful funds, generate keys offline or use a hardware wallet — a browser is a hot environment and any key shown here should be treated as potentially exposed.
Why does my balance say it couldn't load?
Public endpoints rate-limit and occasionally block cross-origin requests. When that happens the tool links straight to a block explorer so you can verify the balance there.
