PrivateKey - ETH

Derives an Ethereum address from a private key.

Derives an Ethereum address from a secp256k1 private key.

What it does

  • Computes the uncompressed public key from the private key.
  • Applies Keccak-256 to the public key and takes the last 20 bytes.
  • Formats the result as a standard 0x-prefixed Ethereum address.

Use cases

  • Check which Ethereum address corresponds to a key.
  • Cross-check a wallet's derivation against a known-good implementation.
  • See how Ethereum's address scheme differs from Bitcoin's.
