MAC!

I am MAC!, or Mina Arbitrated Contracts if you want to be formal. I am an zkApp that makes zkApps (yes, really!).

The best part is you do not even need to know how to code! Go visit https://mac.sqrtxx.com/ to read more about me and try me!

Setup

Install the dependencies for the smart contract, from the root of this repo run

cd contracts

then install the dependencies

npm install

and build it

npm run build

generate the cache

npx tsx scripts/gencompilecache.ts

( re-run it few times to see how the compile time improves with the cache )

and copy the cache to speed-up the compilation in the UI

cd ../
sh copy_cache_ui.sh

pack it to be imported from the UI

npm pack

it should create a file mac-contracts-0.3.0.tgz under same directory. Note the directory path and filename.

now to prepare the UI of the MAC! app, from same directory run

cd ui

to change the UI directory, now update the package.json and set the pack of maccon to the path of mac-contracts-0.3.0.tzg you built in the last step, then install the dependencies

npm install

and run the app locally

npm run dev

Running the build

cd ui/
npm run build
npm run export

Testing the network

If you notice problems connecting to the network via the frontend you can double check possibility to connect via command line as follows

npx tsx contracts/scripts/networkcheck.ts 

example output

testing https://proxy.testworld.minaexplorer.com/graphql
successfully set active instance
failed to fetch last block

testing https://proxy.berkeley.minaexplorer.com/graphql

check the address
