Conventions

The Web3 library follows the following conventions.

Bytes vs Text

• The term bytes is used to refer to the binary representation of a string.
• The term text is used to refer to unicode representations of strings.

Hexadecimal Representations

• All hexadecimal values will be returned as text.
• All hexadecimal values will be 0x prefixed.

Addresses

All addresses must be supplied in one of three ways:

• While connected to mainnet, an Ethereum Name Service name (often in the form myname.eth)
• A 20-byte hexadecimal that is checksummed using the EIP-55 spec.
• A 20-byte binary address.
