BIP38 Wallet — Generate, Recover, Spend

Client-side Bitcoin wallet

Create a protected paper wallet.

Generate a fresh Bitcoin key pair and encrypt its private key with BIP38. Everything happens inside this browser window.

Create a protected wallet

Choose a passphrase and an entropy source. The private key is always returned BIP38-encrypted.

Computer-generated pseudo-randomness Uses the browser’s cryptographic random-number generator.

Physical dice randomness Derive the key from 99 rolls of a six-sided die (B6), then encrypt with BIP38.

How do I make a wallet using dice? What is B6?

An important part of creating a Bitcoin wallet is ensuring the random numbers used to create the wallet are truly random. Physical randomness is better than computer generated pseudo-randomness. The easiest way to generate physical randomness is with dice.

To create a Bitcoin private key you only need one six sided die which you roll 99 times, stopping each time to record the value of the die. When recording the values follow these rules: 1=1, 2=2, 3=3, 4=4, 5=5, 6=0. By doing this you are recording the big random number, your private key, in B6 or base 6 format.

Enter the 99 character base 6 private key below, set your password, and click Generate protected wallet. You will see the Bitcoin address and a BIP38 encrypted private key that requires your password to spend.

Base 6 private key (99 rolls)

Accepts digits 0–5, or 1–6 (6 becomes 0)0 / 99

For real funds: use Download for offline use, disconnect from all networks, then open the file locally. Never upload or share the encrypted-key QR together with its password. Full walkthrough: /guide.

Recover BIP38 to WIF

Decrypt a password-protected BIP38 key to WIF for import into Electrum, Sparrow, BlueWallet, and similar wallets.

Warning: WIF can spend funds immediately. Only recover on a trusted, preferably offline computer.

Sign a spend

Decrypt BIP38, load UTXOs from mempool.space, and create a signed raw transaction hex to copy. Publishing comes later on a separate page.

Note: UTXO lookup uses mempool.space. Signing stays in your browser. Copy the raw hex to publish later.
