vat upgrade in production: Agoric smart wallet supports NFTs

[Dan Connolly]

#49 Upgrade Smart Wallet to support NFTs just completed, in block 11731339 on the Agoric production mainnet chain.

The Persistence and Upgrade problem has been a thorny one for quite some time:

Do you, Programmer,
take this Object to be part of the persistent state of your application,
to have and to hold,
through maintenance and iterations,
for past and future versions,
as long as the application shall live?

--Arturo Bejar

The SwingSet vat-upgrade solution preserves capability security through the upgrade. It's pretty nifty.
