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.

Setup

Node 22 or newer is required.

Option 1: Global install:

# Install with NPM
npm install -g @hyperlane-xyz/cli
# Or uninstall old versions
npm uninstall -g @hyperlane-xyz/cli

Option 2: Temp install:

# Run via NPM's npx command
npx @hyperlane-xyz/cli
# Or via pnpm's dlx command
pnpm dlx @hyperlane-xyz/cli

Option 3: Run from source:

git clone https://github.com/hyperlane-xyz/hyperlane-monorepo.git
cd hyperlane-monorepo
pnpm install && pnpm build
cd typescript/cli
pnpm hyperlane

Address conversion utilities

Convert address to bytes32: hyperlane address to-bytes32 --address <address> [--protocol <protocol>]

Convert bytes32 to address: hyperlane address from-bytes32 --bytes32 <bytes32> --protocol <protocol> [--prefix <prefix> | --chain <chain>]

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.

Address Conversion Utilities

Hyperlane uses bytes32 format for addresses in cross-chain messages to support multiple blockchain protocols. The CLI provides utilities to convert between protocol-specific addresses and bytes32 format.

to-bytes32

Convert an address to bytes32 format (used in Hyperlane messages).

Usage:

hyperlane address to-bytes32 --address <address> [--protocol <protocol>]

Flags:

• --address, -a - The address to convert (required)
• --protocol, -p (optional) - Protocol type: ethereum, sealevel, cosmos, cosmosnative, starknet, radix, aleo, tron. Auto-detected if not specified.

Examples:

# EVM address (auto-detected)
hyperlane address to-bytes32 --address 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266

# Solana address with explicit protocol
hyperlane address to-bytes32 -a EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v -p sealevel

# Cosmos address
hyperlane address to-bytes32 --address cosmos1wxeyh7zgn4tctjzs0vtqpc6p5cxq5t2muzl7ng --protocol cosmos

from-bytes32

Convert bytes32 to an address for a specific protocol.

Usage:

hyperlane address from-bytes32 --bytes32 <bytes32> --protocol <protocol> [--prefix <prefix> | --chain <chain>]

Flags:

• --bytes32, -b - The bytes32 hex string to convert (with or without 0x prefix) (required)
• --protocol, -p - Target protocol type (required)
• --prefix (optional) - Address prefix for Cosmos chains (e.g., "cosmos", "osmo", "neutron") and Radix chains (e.g., "account_rdx")
• --chain, -c (optional) - Chain name to automatically lookup the prefix from registry (e.g., "osmosis", "neutron", "cosmoshub"). Cannot be used with --prefix.

Examples:

# Convert to EVM address
hyperlane address from-bytes32 --bytes32 0x000000000000000000000000f39fd6e51aad88f6f4ce6ab8827279cfffb92266 --protocol ethereum

# Convert to Solana address (using aliases)
hyperlane address from-bytes32 -b 0xc6fa7af3bedbad3a3d65f36aabc97431b1bbe4c2d2f6e0e47ca60203452f5d61 -p sealevel

# Convert to Cosmos address with explicit prefix
hyperlane address from-bytes32 --bytes32 0x00000000000000000000000071b24bf8489d5785c8507b1600e341a60c0a2d5b --protocol cosmos --prefix cosmos

# Convert to Osmosis address using chain lookup
hyperlane address from-bytes32 -b 0x00000000000000000000000071b24bf8489d5785c8507b1600e341a60c0a2d5b -p cosmos --chain osmosis

# Convert to Neutron address using chain name
hyperlane address from-bytes32 -b 0x00000000000000000000000071b24bf8489d5785c8507b1600e341a60c0a2d5b -p cosmos -c neutron

Supported Protocols:

• ethereum - EVM-compatible chains (Ethereum, Polygon, Arbitrum, etc.)
• sealevel - Solana and SVM chains
• cosmos - Cosmos SDK chains using CosmWasm
• cosmosnative - Cosmos SDK chains using native modules
• starknet - StarkNet
