 # Axelar CGP Sui
 
-An implementation of the Axelar gateway for the Sui blockchain.
+An implementation of the Axelar cross-chain contracts in Move for the Sui blockchain.
 
 ## Installation
 
-Install Sui and run a local Sui network: https://docs.sui.io/build/sui-local-network.
-The copy `.env.exaple` to `.env` and add a valid private key for sui. If you want to deploy to testnet you shoukd have its address be funded.
+Install Sui as shown [here](https://docs.sui.io/guides/developer/getting-started/sui-install)
 
-## Deployment
+Install node.js 18+
+
+Build all Move packages
+
+```sh
+npm ci
 
-To deploy to testnet run `node scripts/publish-package axelar testnet` 
+npm run build
+```
 
 ## Testing
 
-run `npm run test` to run move tests on all the move packages.
+Run tests for all Move packages
+
+```sh
+npm run test
+```
+
+### Development
+
+If using VS Code, install `move-analyzer` via `cargo`,
+
+```sh
+cargo install --git https://github.com/move-language/move move-analyzer --features "address20"
+```
+
+Next, install the `move-analyzer` extension in VS Code.
+
+## Deployment
+
+Copy `.env.example` to `.env` and add a valid private key for sui. If you want to deploy to testnet the corresponding address should be funded.
+
+Run a [local](https://docs.sui.io/build/sui-local-network) Sui network for local testing, or use testnet.

 The gateway lives in a few modules but has all of its storage in a single shared object called `AxelarValidators`. This is not very aptly named and we might rename it.
 
+## Relayer Spec
+
+Relaying to Sui is a bit complicated: the concept of 'smart contracts' is quite warped compared to EVM chains.
+
+### The Problems
+
+Firstly, all persistent storage stems from `Objects` that have the `key` property and are either shared or owned by an account. These objects have a specific `type`, which is defined in a certain module, and only that module can access their storage (either to read or to write to it). This means that instead of calling a smart contract with some data, in Sui one needs to call a module, pass the Objects that are to be modified as arguments, alongside extra arguments that specify the kind of change that should occur. This additionally means that the concept of `msg.sender` does not apply to applications, and a certain `capability` object that functions like a 'key' to unlock certain functionality needs to be used instead.
+
+The second issue is the lack of interfaces whatsoever. It is impossible for a module to ever call a module that is published at a later time. This means applications that want to interface with future applications must be called by those future applications, but need to call pre-existing ones. To expand on this, we expect contract calls that are received to potentially modify the storage of multiple objects in a single call, which makes it impossible to require modules to implement a 'standardized' function that a relayer will call, because the number of arguments required varies depending on the application (or the type of call).
+
+Finally, we do not want to require the payload of incoming calls to have a certain format, because that would mean that working applications that want to exapnd to Sui need to redesign their working protocoll to accomodate Sui, discouraging them from doing so.
+
+### The Solutions
+
+First of all, as we mentioned before, for applications to 'validate' themselves with other applications need to use a `capability` object. This object will be called `Channel`, and it will hold information about the executed contract calls as well. It has a field called `id` which specifies the 'address' of the application for the purposed of incoming and outgoing extenral calls. This `id` has to match the `id` of a shared object that is passed in the channel creation method (alongside a witness for security). This shared object can easily be querried by the relayer to get call fullfilment information. Specifically:
+
+- The shared object has to have a field called `get_call_info_object_ids` that is a `vector<address>`.
+- The module that defined the shared object type has to implement a function called `get_call_info`, which has no types, and takes the incoming call `payload` as the first argument, followed by a number of shared objects whose ids are specified by the `get_call_info_object_ids` mentioned above. This function has to return a `std::ascii::String` which is the JSON encoded call data to fullfill the contract call.
+- This calldata has the following 3 fields:
+  - `target`: the target method, in the form of `packag_iId::module_name::function_name`.
+  - `arguments`: an array of arguments that can be:
+    - `contractCall`: the `ApprovedCall` object (see below).
+    - `pure:${info}`: a pure argument specified by `$info`.
+    - `obj:${objectId}`: a shared object with the specified `id`.
+  - `typeArguments`: a list of types to be passed to the function called
