DARs

The DARs tab lists every Daml package the participant knows about, and lets you upload new ones.

Columns

Column	Contents
Name	The package name.
Version	The package version.
Package ID	The full package hash, truncated, with a copy button.
Size	Package size.
Known since	When the participant first saw the package.

Searching

The search box matches on name, version, or package ID, and is forgiving: it matches substrings and in-order character sequences, so partial or approximate terms work. Search results replace the table; clear the box to return to the full list.

Uploading a DAR

1

Click Upload .dar

A file picker opens, filtered to .dar files.

2

Choose the file

An upload strip appears below the toolbar showing the file name, its size, a progress bar, and the status Ready to upload.

3

Click the upload button

The status changes to Uploading… and the progress bar advances.

4

Check the result

On success the status becomes Uploaded <filename> and the package list refreshes. On failure the error message from the participant is shown in place of the status.

Use the dismiss button to clear the strip and pick a different file.

There is no confirmation step. Clicking upload sends the DAR to the participant immediately. Uploading a Daml package cannot be undone — packages are permanent on the ledger — so check you have the right file and the right validator first.

The file picker will accept a file that is not really a DAR. Validation happens on the participant, so an invalid file produces an upload error rather than being rejected in the browser.

Very large DARs may be rejected before reaching the participant, by the request size limit on the API. If a large upload fails with a size-related error rather than a Daml error, raise it with IntellectEU support — the limit is a platform setting, not something you can change from the UI.
