This is a continuation of my previous proposals, the last one being here.

Returning Note
As you may have noticed, there was no proposal from me for the month of June.
This is because, as announced in the previous thread, I decided to take a summer vacation in the month of June instead of August like I did last year.

Due to unexpected circumtansces, I wasn't able to return to work on the first of July. Instead, I started on Monday 15th. Because of this, and because I might be taking a few days off to finish some business in my personal life (Specifically Friday 19 and Monday 22), I will be asking for 10000 PIV for this month of July.

Starting from August, I continue making my regular proposals, but I will not make another progress report, due to the short amount of time between the two.

MPW work
These months were focused on optimizing MPW, specifically for those with a slow connection.
The main bundle size, was cut down from 455KB to 325KB, a ~28% reduction in size. This was achieved with the following PRs:

• https://github.com/PIVX-Labs/MyPIVXWallet/pull/355 Minimize countries.json
  We use country-locale-map to auto-detect currencies based on the user's language. However, this brings a lot of useless data, this PR tells webpack to include just the data we need.
• https://github.com/PIVX-Labs/MyPIVXWallet/pull/366 Use countries.json directly instead of the provided functions to skip some of the imports
• https://github.com/PIVX-Labs/MyPIVXWallet/pull/360 Polyfill crypto with noble
  Quite a few dependencies depended on the crypto library, but we already had a noble library available. This PR replaces crypto with noble.
• https://github.com/PIVX-Labs/MyPIVXWallet/pull/367 Polyfill all the secp256k1 with @noble/secp256k1.
  A in house replacement was made for secp256k1-noble, and tested using the same tests for the original library, which can be found here https://github.com/PIVX-Labs/secp256k1-noble
• https://github.com/PIVX-Labs/MyPIVXWallet/pull/365 Cache and prefetch shield files.
  This removes a bunch of initial download time because each shield helper script was previously fetched once per core each time MPW was opened. This not only makes it effectively fetch it one time, it also caches it between sessions.
• https://github.com/PIVX-Labs/MyPIVXWallet/pull/313 Update txid in fromHex
  This speeds up the calculation of txids, specifically for systems with slow CPUs.

Additionally, a number of improvements were made:

• https://github.com/PIVX-Labs/MyPIVXWallet/pull/369 Auto deshield transactions when sending to a transparent/exchange address, by automatically using a burner transparent address.
• https://github.com/PIVX-Labs/MyPIVXWallet/pull/325 Rewrite stake tab in vue
• https://github.com/PIVX-Labs/MyPIVXWallet/pull/318 Add commit hash to dev builds
• https://github.com/PIVX-Labs/MyPIVXWallet/pull/322 Export extended sapling spending key as well as xpriv
• https://github.com/PIVX-Labs/MyPIVXWallet/pull/336 Resync from scratch if sapling root is different that what's advertised.
  This helps in cases where the explorer might fork, previously a manual resync was necessary
