How do I use the "Optional Tag" field in the GUI light wallet?

Question

• What exactly is this field for?
• What format is the "tag" supposed to be in?
• Does the recipient see it? Does this info survive a snapshot?

Answer 1

It just adds an user-defined tag to your transaction.

Format

It contains 27 trytes (=uppercase ABCDEFGHIJKLMNOPQRSTUVWXYZ and the number 9)

• If you enter "MY9CUSTOM9TAG" the actual tag will be MY9CUSTOM9TAG99999999999999
• If you leave the field empty, the tag will be 999999999999999999999999999

• The recipient sees it.
• It can be viewed in Tangle explorers (like thetangle.org)
• It does not survive snapshots but you can still look at it in Tangle explorers that support viewing transactions before snapshots

Current usage

• If you want to quickly find your transaction you can add a tag (e.g. BRENT9BUTLER) to your transactions and search by tag in a Tangle explorer
• You can leave friendly messages with your transfers
