I don't think we can fix the SDK simulations, as the deposit fees generation does not take in account our minimum deposit constraint. Fixing e2e however. |

This shouldn't be under x/ as it's not a module.

Could you give more context on this change and how it tests the new ante handler?

unit tests and e2e tests need to be added:
- gov proposal with deposit less than
MiniumInitialDepositRate - gov proposal with deposit more than/equal to
MiniumInitialDepositRate - authz.msg contains gov proposal with deposit less than
MiniumInitialDepositRate - authz.msg contains gov proposal with deposit more than/equal to
MiniumInitialDepositRate

the depositAmount = 3,300uatom, is this enough ? depositAmount need to be >= 2,000,000uatom due to
MiniumInitialDepositRate = sdk.NewDecWithPrec(10, 2), gas = 200,000

if deposit IsAllLT than the required deposit, fail.
may use
if deposit IsAnyGTE than the required deposit, pass. This can do a fast looping, when find one coin GTE, return nil ?
both are fine

@yaruwangway would you mind doing the changes? I will let the pro do it. |

Closes: #2246.
This should fix the spam issue from the Cosmos Hub.
This ports CosmosContracts/juno#394 from @vuong177 and @faddat.
