Local Wallet Standard

Lightweight Wallet Signer CLI — generate wallets, derive addresses, and sign messages across EVM, Solana, Bitcoin, Cosmos, and Tron chains.

LWS CLI

Minimal, offline-first CLI for generating wallets, deriving addresses, and signing messages across multiple chains.

Installation

One-liner:

bash

curl -fsSL https://raw.githubusercontent.com/dawnlabsai/lws/main/lws/install.sh | bash

The installer will:

1. Install Rust via rustup if not already present
2. Clone the repo and build from source
3. Place the lws binary at ~/.lws/bin/lws
4. Add ~/.lws/bin to your shell's PATH (supports zsh, bash, fish)

Set LWS_INSTALL_DIR to override the install location.

From source:

bash

git clone https://github.com/dawnlabsai/lws.git
cd lws/lws
cargo build --workspace --release
cp target/release/lws ~/.lws/bin/lws
