The factory contract can perform creation of secretswap pair contract and also be used as directory contract for all pairs.

Register verified pair contract and token contract for pair contract creation. The sender will be the owner of the factory contract.

{
    /// Pair contract code ID, which is used to
    pub pair_code_id: u64,
    pub token_code_id: u64,
    pub init_hook: Option<InitHook>,
}

UpdateConfig

The factory contract owner can change relevant code IDs for future pair contract creation.

{
    "update_config":
    {
        "owner": Option<HumanAddr>,
        "pair_code_id": Option<u64>,
        "token_code_id": Option<u64>,
    }
}

Create Pair

When a user execute CreatePair operation, it creates Pair contract and LP(liquidity provider) token contract. It also creates not fully initialized PairInfo, which will be initialized with Register operation from the pair contract's InitHook.

{
  "create_pair": {
    "asset_infos": [
      {
        "token": {
          "contract_addr": "terra1~~"
        }
      },
      {
        "native_token": {
          "denom": "uusd"
        }
      }
    ]
  }
}

Register

When a user executes CreatePair operation, it passes InitHook to Pair contract and Pair contract will invoke passed InitHook registering created Pair contract to the factory. This operation is only allowed for a pair, which is not fully initialized.

Once a Pair contract invokes it, the sender address is registered as Pair contract address for the given asset_infos.

{ "register":
    "asset_infos": [{
        "token": {
            "contract_addr": "terra1~~",
            }
        }, {
            "native_token": {
                "denom": "uusd",
            }
    }],
}
