Interacting with other contracts

Interacting with Intelligent Contracts

As GenLayer calldata is dynamically typed users can send whatever they want to a contract, or use statically typed interface to facilitate type checking and autocompletion

🏗️

Exact parameters of .view() and .write() are subject to change

Dynamically typed approach

address = Address("0x03FB09251eC05ee9Ca36c98644070B89111D4b3F")
result = gl.ContractAt(address).view().method_name(1, '234')
gl.ContractAt(address).write(gas=10**5).method_name(1, '234')
# ^ write methods do not return anything!

Statically typed approach

@gl.contract_interface
class GenLayerContractIface:
    class View:
        def method_name(self, a: int, b: str): ...
 
    class Write:
        pass
 
### in your contract method ###
 
address = Address("0x03FB09251eC05ee9Ca36c98644070B89111D4b3F")
result = GenLayerContractIface(address).view().method_name(1, '234')

Interacting with Ghost Contracts

Eth contracts have statically typed calldata format, which means that only statically typed approach with interfaces is applicable

🏗️

This is not supported in the Studio right now

@gl.ghost_contract
class GhostContractIface:
    class View:
        def method_name(self, param: str, /) -> tuple[u32, str]: ...
 
    class Write:
        def bar(self, param: str, /): ...
 
### in your contract method ###
 
address = Address("0x03FB09251eC05ee9Ca36c98644070B89111D4b3F")
i, s = GhostContractIface(address).view().method_name('234')
