Router

Query Messages

note

We will only go through the queries for this contract, as users are not allowed to execute any messages on the Router contract directly. You can read about the Router architecture here

List of queries that can be performed on the Router contract.

GetState

Quries the state of the contract.

pub enum QueryMsg {
    #[returns(StateResponse)]
    GetState {},
}

{"get_state":{}}

The query returns the following response:

pub struct StateResponse {
    pub admin: String,
    pub vlp_code_id: u64,
    pub vcoin_address: Option<Addr>,
    pub locked: bool,
}

Name	Type	Description
admin	`String`	The admin address, which is the only address allowed to call messages on the contract.
vlp_code_id	`u64`	The code_id used to instantiate new VLP contracts on the hub chain.
vcoin_address	`Option<Addr>`	The address of the Virtual Balance contract used by the router.
locked	`bool`	Whether the contract is locked or not.

GetChain

Queries information about the specified chain.

pub enum QueryMsg {
    #[returns(ChainResponse)]
    GetChain { chain_uid: ChainUid },
}

{"get_chain":{"chain_uid":"chainA"}}

Name	String	Description
chain_uid	ChainUid	The unique Id of the chain to get info for.

The query returns the following response:

pub struct ChainResponse {
