How it works

  • BTC and ETH both use the same secp256k1 curve, so a single 32-byte key derives addresses on both chains.
  • ETH address = last 20 bytes of keccak256(pubkey_xy), then EIP-55 checksum casing.
  • BTC P2PKH = base58check(0x00 || RIPEMD160(SHA256(pubkey))).
  • WIF (Wallet Import Format) is the base58check encoding of the private key for use in Bitcoin Core / Electrum.

Never paste a real private key controlling real funds into a website.

This tool computes everything locally with no network calls, but you cannot verify that with the naked eye. Use it only for testnet keys, learning, and burner wallets.
