rABCdd17b5dae543: [Cashtab] Update tx history to parse eCashChat authentication txs

Summary

v1.5.2 of eCashChat will utilize onchain authentication transactions to verify ownership of addresses on mobile devices. This is done by passing a BIP21 querystring to Cashtab.com on mobile devices with a pre-populated dust send tx.

It's done this way because the use of signature verification is very laborious and Cashtab Extensions is not available on Android/iOS.

This diff updates Cashtab to recognize these transactions.

cashtab/src/chronik/index.js
204	this file isn't being changed at all by this diff...can you back out these formatting changes?
cashtab/src/components/Home/Tx/index.js
450	would be nice to include a brief spec of what such a tx is expected to look like in the parsing is there no case for "invalid auth tx" ? Just any app tx with the prefix and then anything else is an auth tx? if so, worth mentioning in a comment. Do you have a spec for the many types of ecash chat txs now possible somewhere? could add this to the monorepo doc? or mb a dev section on ecash chat?

This revision now requires changes to proceed.Aug 11 2024, 14:06

Updated comments

cashtab/src/components/Home/Tx/index.js
450	Added comment to indicate authentication tx opreturns are basically authPrefixHex + a random string. A websocket listens for a tx with an opreturn that contains that random string and if so, authenticates the sending address. Latest spec is available here: https://github.com/ethanmackie/ecash-chat/blob/uat/README.md I will update the monorepo prefix doc separately.
