Additional context

Upgrade 14 RC0 testing against http://bafybeiaacac4p2xuuljvwdgzr4dgh3zgjw6w2lm4h4ut3qbf4b5nyoximy.ipfs.cf-ipfs.com/?#/vaults ~2 weeks ago was successful - did not run into this same issue

Screenshots

From @samsiegart: It seems when we updated @agoric/cosmic-proto in dapp-inter we were seeing issues broadcasting transactions. It might be because of the message types that we import here not matching what the upgrade-14 chain expects (would they be different)?

[samsiegart]

Closing this because the broken version was never an endorsed UI in mainnet, emerynet, or elsewhere. It was just the latest main that was broken at one point and is now fixed as of https://github.com/Agoric/dapp-inter/pull/253.
