About this network

Ethereum uses the same secp256k1 key pair as Bitcoin for ECDSA. The address is the last 20 bytes of Keccak-256 applied to the uncompressed public key (without the 0x04 prefix), displayed as hex with EIP-55 checksum. Balances and contracts refer to this single account format.

Address formats from your private key

• Externally owned account (EOA)

  A standard Ethereum wallet address: 20-byte identifier from your public key, shown as 0x-prefixed hex; used for sending ETH and interacting with contracts.
