Hyperlane CLI

The Hyperlane CLI is a command-line tool written in Typescript that facilitates common operations on Hyperlane, such as deploying the core contracts and/or warp routes to new chains.

Hyperlane overview

Hyperlane is an interchain messaging protocol that allows applications to communicate between blockchains.

Developers can use Hyperlane to share state between blockchains, allowing them to build interchain applications that live natively across multiple chains.

To read more about interchain applications, how the protocol works, and how to integrate with Hyperlane, please see the documentation.

Logging

The logging format can be toggled between human-readable vs JSON-structured logs using the LOG_FORMAT environment variable or the --log <pretty|json> flag.

Note: If you are unable to see color output after setting LOG_FORMAT, you may set the FORCE_COLOR=true environment variable as a last resort. See https://force-color.org/ & https://github.com/chalk for more info.

The logging verbosity can be configured using the LOG_LEVEL environment variable or the --verbosity <trace|debug|info|warn|error|off> flag.
