Released April 26, 2026

​
New features

​
Plugins

The CLI now supports plugins — npm packages that add new commands to umbra. Install one and its commands are available immediately, no restart required: 
umbra plugin add jup-earn
Manage installed plugins from the terminal: Each plugin can be pinned to its own active user, so one plugin can sign with a different wallet than the one set globally.

​
Interactive token picker

You can now omit the <mint> argument on token commands and pick from a list of supported mints fetched from the relayer. Common tokens like USDC, USDT, Wrapped SOL, and UMBRA are shown by symbol: 
umbra eta deposit
umbra eta balance
umbra eta withdraw
umbra utxo create
Pass a mint address directly to skip the picker, same as before. See eta deposit and related commands for details.

​
Updates

​
Streamlined install

The post-install script has been removed. Installs are quieter and faster, and there’s nothing extra to configure after npm install -g umbraprivacy-cli.

​
Release pipeline

Releases now ship to npm more reliably, so new versions land on npm install without manual intervention.
