Solidity Datatypes List

solidity_datatypes.md

value types and reference types don't need to be referred to as such in the UI.

We might want to support a backup UI that allows inputting encoded constructor args in cases where a constructor argument is a struct, as that makes the UI more complicated.

Value Types

• uint

  • default is uint256, and can be specified in intervals of 8 like uint8, uint16, etc.
  • uint256 matches regex ^\d{0,79}$

• int

  • default is int256, and can be specified in intervals of 8 like int8, int16, etc.
  • int256 matches regex ^-?\d{0,78}$

• address

  • matches regex ^(0x)?[a-fA-F0-9]{40}$

• bytes

  • matches regex ^(0x)?[a-fA-F0-9]*$

• boolean

  • only true or false

Reference Types

these types are combinations or arrays of value types: please see this article for more information
