Tx metadata support

[NeonSpaceTurtle]

Hey, with the historical epoch 258 on its way in a few days it would be great if we have the option to include metadata with transactions to participate properly. Could you please implement it soon enough?

We would like to add metadata support but it's not the priority right now so unfortunately it won't by available by epoch 258. The most direct way of submitting metadata we are aware of is via the cardano-cli tool which is described in the article as well and if you have a hardware wallet, you can use cardano-hw-cli to sign a transaction built by the cardano-cli tool. However the pull request with metadata support has not been merged yet, so you'd need to build the tool from the source code

The approach described above is technical, unfortunately, but it's the only option available right now apart from tools where you submit the metadata via a third party like the ones described in the article you referenced
