Generate educational Bitcoin and Ethereum-style keypair examples to learn how wallet creation works.
Educational use only — never use these keys for real funds.
Never share or store a private key you intend to use.
These keys are generated in your browser but use a simplified derivation, not production-grade elliptic-curve math.
For real wallets, use a hardware wallet (Ledger, Trezor) or audited software (MetaMask, Bitcoin Core).

Select a cryptocurrency and click Generate. A fresh 32-byte private key is created using crypto.getRandomValues() — the same entropy source browsers use for secure tokens.
