Install ARC CLI

Install arc before continuing to the site steps. The installer resolves the current published release on its own, so there is no version number to copy off this page.

Install

On macOS, run the official installer:

curl -fsSL https://arc.arcblock.io/install.sh | bash

The command downloads ARC CLI, verifies the downloaded archive against a checksum published from a second, independent origin, and installs the executable under ~/.arc. When verifiable release-signing metadata is available, the installer checks it too; the current unsigned fallback warns and continues. The installer tells you which PATH configuration it writes. If the current shell does not find arc yet, open a new terminal before continuing.

Confirm the version

arc --version

Every build prints its version:

<version>

Newer builds add the short commit they were built from and its build date, as <version> (<commit>) <build date>. Both forms are correct.

Note down the version you get. Most pages in this section carry the ARC version their evidence was captured on. Where that is older than what you just installed, read Version compatibility and repeat that page's checks against your own version instead of assuming the output matches. To reproduce a page's captured output exactly, install its version instead by appending -s -- --version <v> to the command above.

Installing the CLI does not deploy a blocklet or create or sign in to a DID Space. Continue with Requirements and scope.
