 # CW1 Spec: Proxy Contracts
 
-CW1 is a specification for proxy contracts based on CosmWasm.
-It is a very simple, but flexible interface designed for the case
-where one contract is meant to hold assets (or rights) on behalf of
-other contracts.

-The simplest example is a contract that will accept messages from
-the creator and resend them from its address. Simply by making this
-transferable, you can then begin to transfer non-transferable assets
-(eg. staked tokens, voting power, etc).

-You can imagine more complex examples, such as a "1 of N" multisig,
-or conditional approval, where "sub-accounts" have the right to spend
-a limited amount of funds from this account, with a "admin account"
-retaining full control.

-The common denominator is that they allow you to immediately

 ### Messages
 
-`Execute{msgs}` - This accepts `Vec<CosmosMsg>` and checks permissions
-before re-dispatching all those messages from the contract address.
+`Execute{msgs}` - This accepts `Vec<CosmosMsg>` and checks permissions before re-dispatching all those messages from the

+
+| Key      | Value        |
+| -------- | ------------ |
+| "action" | "execute"    |
+| "owner"  | [msg sender] |
 
 ### Queries
 
-`CanExecute{sender, msg}` - This accepts one `CosmosMsg` and checks permissions,
-returning true or false based on the permissions. If `CanExecute` returns true
-then a call to `Execute` from that sender, with the same message, 
-before any further state changes, should also succeed. This can be used 
-to dynamically provide some client info on a generic cw1 contract without 
-knowing the extension details. (eg. detect if they can send coins or stake)
