cast to-bytes32

TRY ONLINE

EXAMPLES

Just adds zeros to the hex string on the right, until it is 32 bytes (hex can be with or without 0x):

cast to-bytes32 0x1

0x1000000000000000000000000000000000000000000000000000000000000000

It needs to be a hex string, it won't work with normal strings, e.g. it will work with '1234abc' but won't work with '1234xyz':

cast to-bytes32 1234abc

0x1234abc000000000000000000000000000000000000000000000000000000000

Often used to right pad zeros to addresses, for example when the address needs to be 32 bytes:

cast to-bytes32 0xbd20e68967fc2a813356bff4754bba48692d8e0d

0xbd20e68967fc2a813356bff4754bba48692d8e0d000000000000000000000000

DOCUMENTATION

Right-pads hex data to 32 bytes

$ cast to-bytes32 --help

Usage: cast to-bytes32 [OPTIONS] [BYTES]

Arguments:
  [BYTES]
          The hex data to convert

Options:
  -h, --help
          Print help (see a summary with '-h')

  -j, --threads <THREADS>
          Number of threads to use. Specifying 0 defaults to the number of
          logical cores
          
          [aliases: --jobs]

Display options:
      --color <COLOR>
          The color of the log messages

          Possible values:
          - auto:   Intelligently guess whether to use color output (default)
          - always: Force color output
          - never:  Force disable color output

      --json
          Format log messages as JSON

  -q, --quiet
          Do not print log messages

  -v, --verbosity...
          Verbosity level of the log messages.
          
          Pass multiple times to increase the verbosity (e.g. -v, -vv, -vvv).
          
          Depending on the context the verbosity levels have different meanings.
          
          For example, the verbosity levels of the EVM are:
          - 2 (-vv): Print logs for all tests.
          - 3 (-vvv): Print execution traces for failing tests.
          - 4 (-vvvv): Print execution traces for all tests, and setup traces
          for failing tests.
          - 5 (-vvvvv): Print execution and setup traces for all tests,
          including storage changes.
