-## MsgProveOutboundTx
-
-Casts a vote on an outbound transaction observed on a connected chain (after
-it has been broadcasted to and finalized on a connected chain). If this is
-the first vote, a new ballot is created. When a threshold of votes is
-reached, the ballot is finalized. When a ballot is finalized, the outbound
-transaction is processed.
-
-If the observation is successful, the difference between zeta burned
-and minted is minted by the bank module and deposited into the module
-account.
-
-If the observation is unsuccessful, the logic depends on the previous
-status.
-
-If the previous status was `PendingOutbound`, a new revert transaction is
-created. To cover the revert transaction fee, the required amount of tokens
-submitted with the CCTX are swapped using a Uniswap V2 contract instance on
-ZetaChain for the ZRC20 of the gas token of the receiver chain. The ZRC20
-tokens are then
-burned. The nonce is updated. If everything is successful, the CCTX status is
-changed to `PendingRevert`.
-
-If the previous status was `PendingRevert`, the CCTX is aborted.
