This repository contains a modified version of the CloudFlare wrangler deployed in the Stellar FCA00C Challenge.
Unlike the actual deployment, this implementation only contains the logic for gathering the users' performance (namely CPU and size).
When a user submits a solution, a local soroban-host-env is spun up in which the uploaded WASM is sandboxed and executed.
As the wrangler is written in Rust we need to have the rust toolchain and cargo installed.
The wrangler utilizes a build.rs to automatically source all required dependencies, which are given as WASM files, and includes them as handy constants in the
fca00c:embedded:contracts package.
To compile the rust code into a wrangler readable format, we need to have worker-build installed.
The installation of this binary is already included in the make all script.
After we set up everything (by just running make all), we are able to deploy the wrangler using the default wrangler.
To run the wrangler locally, one can utilize wrangler dev, or alternatively make local.

If the result is not 200: the field message will contain further information.
This endpoint requires authorization.
The parameter task is as defined above.
The body of this request must contain the soroban contract to be submitted in WASM format. The body is to be submitted as binary blob.
If successful (200):
