# Governance
|
|
|
|
This document gives an overview of how the various governance
|
|
proposals interact with the CosmWasm contract lifecycle. It is
|
|
a high-level, technical introduction meant to provide context before
|
|
looking into the code, or constructing proposals.
|
|
|
|
## Proposal Types
|
|
We have added 5 new wasm specific proposal types that cover the contract's live cycle and authorization:
|
|
|
|
* `StoreCodeProposal` - upload a wasm binary
|
|
* `InstantiateContractProposal` - instantiate a wasm contract
|
|
* `MigrateContractProposal` - migrate a wasm contract to a new code version
|
|
* `UpdateAdminProposal` - set a new admin for a contract
|
|
* `ClearAdminProposal` - clear admin for a contract to prevent further migrations
|
|
|
|
For details see the proposal type [implementation](https://github.com/CosmWasm/wasmd/blob/master/x/wasm/internal/types/proposal.go)
|
|
|
|
A wasm message but no proposal type:
|
|
* `ExecuteContract` - execute a command on a wasm contract
|
|
|
|
### Unit tests
|
|
[Proposal type validations](https://github.com/CosmWasm/wasmd/blob/master/x/wasm/internal/types/proposal_test.go)
|
|
|
|
## Proposal Handler
|
|
The [wasmd proposal_handler](https://github.com/CosmWasm/wasmd/blob/master/x/wasm/internal/keeper/proposal_handler.go) implements the `gov.Handler` function
|
|
and executes the wasmd proposal types after a successful tally.
|
|
|
|
The proposal handler uses a [`GovAuthorizationPolicy`](https://github.com/CosmWasm/wasmd/blob/master/x/wasm/internal/keeper/authz_policy.go#L29) to bypass the existing contract's authorization policy.
|
|
|
|
### Tests
|
|
* [Integration: Submit and execute proposal](https://github.com/CosmWasm/wasmd/blob/master/x/wasm/internal/keeper/proposal_integration_test.go)
|
|
|
|
## Gov Integration
|
|
The wasmd proposal handler can be added to the gov router in the [abci app](https://github.com/CosmWasm/wasmd/blob/master/app/app.go#L306)
|
|
to receive proposal execution calls.
|
|
```go
|
|
govRouter.AddRoute(wasm.RouterKey, wasm.NewWasmProposalHandler(app.wasmKeeper, enabledProposals))
|
|
```
|
|
|
|
## Wasmd Authorization Settings
|
|
|
|
Settings via sdk `params` module:
|
|
- `code_upload_access` - who can upload a wasm binary: `Nobody`, `Everybody`, `OnlyAddress`
|
|
- `instantiate_default_permission` - platform default, who can instantiate a wasm binary when the code owner has not set it
|
|
|
|
See [params.go](https://github.com/CosmWasm/wasmd/blob/master/x/wasm/internal/types/params.go)
|
|
|
|
### Init Params Via Genesis
|
|
|
|
```json
|
|
"wasm": {
|
|
"params": {
|
|
"code_upload_access": {
|
|
"permission": "Everybody"
|
|
},
|
|
"instantiate_default_permission": "Everybody"
|
|
}
|
|
},
|
|
```
|
|
|
|
The values can be updated via gov proposal implemented in the `params` module.
|
|
|
|
### Enable gov proposals at **compile time**.
|
|
As gov proposals bypass the existing authorzation policy they are diabled and require to be enabled at compile time.
|
|
```
|
|
-X github.com/CosmWasm/wasmd/app.ProposalsEnabled=true - enable all x/wasm governance proposals (default false)
|
|
-X github.com/CosmWasm/wasmd/app.EnableSpecificProposals=MigrateContract,UpdateAdmin,ClearAdmin - enable a subset of the x/wasm governance proposal types (overrides ProposalsEnabled)
|
|
```
|
|
|
|
### Tests
|
|
* [params validation unit tests](https://github.com/CosmWasm/wasmd/blob/master/x/wasm/internal/types/params_test.go)
|
|
* [genesis validation tests](https://github.com/CosmWasm/wasmd/blob/master/x/wasm/internal/types/genesis_test.go)
|
|
* [policy integration tests](https://github.com/CosmWasm/wasmd/blob/master/x/wasm/internal/keeper/keeper_test.go)
|
|
|
|
## CLI
|
|
|
|
```shell script
|
|
wasmd tx gov submit-proposal [command]
|
|
|
|
Available Commands:
|
|
wasm-store Submit a wasm binary proposal
|
|
instantiate-contract Submit an instantiate wasm contract proposal
|
|
migrate-contract Submit a migrate wasm contract to a new code version proposal
|
|
set-contract-admin Submit a new admin for a contract proposal
|
|
clear-contract-admin Submit a clear admin for a contract to prevent further migrations proposal
|
|
...
|
|
```
|
|
## Rest
|
|
New [`ProposalHandlers`](https://github.com/CosmWasm/wasmd/blob/master/x/wasm/client/proposal_handler.go)
|
|
|
|
* Integration

|
```shell script
|
|
gov.NewAppModuleBasic(append(wasmclient.ProposalHandlers, paramsclient.ProposalHandler, distr.ProposalHandler, upgradeclient.ProposalHandler)...),
|
|
```
|
|
In [abci app](https://github.com/CosmWasm/wasmd/blob/master/app/app.go#L109)
|
|
