Add transaction tips (aka "meta transactions") - proto definitions #9406
Comments
@aaronc @clevinson @gamarin2 is there more context on this somewhere? I've talked it through with @clevinson and get the gist, but wondering if there are any design/architecture docs, requirements, or discussions around? |
This needs #9585 because we must only charge a tip if there was enough gas, so we need processing both before and after running msgs. |

This issue has been renamed to only deal with Proto definitions. The next step is to add a tx middleware, which is discussed in #9912. |
how's it different from feegrant module? https://docs.cosmos.network/master/modules/feegrant/ |
This is to support multi-denom fees along the lines of Ethereum meta-transactions. @gamarin2 can you share more details?
See #9912 for implementation
