There's no full verification of anything on the dollar side that is genuinely possible, BUT yes Taro and open stablecoins do remove one side of the obscurity over how much is being issued. It at least gives a public stablecoin audit to compare it to.

Yes. I'm imagining that part of the public attestation by the custodying party could effectively defer the claim to a 3rd party with some sort of read-only API access. With the various neobank and neobroker products now available, the company managing the claim liabilities via Taro and the one actually custodying the underlying assets would be separate.
