Concerns

• PublicKey.empty() returns an address - B62qiTKpEPjGTSHZrtM8uXiKgn8So916pLmNJKDhKeyBQL9TDb3nvBG
• Is this what it is supposed to be? How do you represent empty values?
• StackOverflow occured with 3 properties of same type (Dicsicpline) example on branch additional-properties
• using structs with nextjs and not in a useEffect results in navigator not defined
• Does a txnSigned.isSuccess mean the contract was successful?
• If not failures will cause the firestore to become out of sync
• if so is it secure to run on the client?
• off-chain solution brittle
• is the use of firebase, merklemaps, and contracts client side secure??

• using structs with nextjs and not in a useEffect results in navigator not defined

type DashboardState = { martialArtsLoaded: boolean, martialArts: Array, } export default function Dashboard() {

let [state, setState] = useState({
martialArtsLoaded: false, martialArts: [], });

How do I deploy smart contracts that do not inherit from SmartContract directly?

The code in the zkapp-cli looks specifically for classes that inherit from SmartContract You could probably walk up the tree

[anandcsingh]

Compilation for simple contracts takes to long Up to 2 mins for simple contracts

How do I develop the web app using the local Blockchain to speed up development?

[anandcsingh]

Interacting with multiple contracts from the same web app was problematic first contract was loaded second contract failed to send/get data stating zkapp could not be found, call fetchAccount but that did not work

[anandcsingh]

Sending multiple transactions one after the other fails with the following error message. The transactions were in a loop that do not change state

Error: Failed to send transaction {
  statusCode: 200,
  statusText: `Couldn't send zkApp command: ["Insufficient_replace_fee"]`
}

[anandcsingh]

Calling fetchAccount from the zkApp UI with larger contract takes very long Impractical AllMartialArtsEvents

[anandcsingh]

My contract takes 4 + mins to comiple that is not the end version The end version throws an exception trying to compile or deploy cant recall ATM

Office hours eluded me,

• I would have a problem before office hours
• struggle get some success
• So I had to just work no need for help
• Office hours would come around
• After office hours another problem would come up
• Stuggle
• Success
• Work
• Office Hours
• Problem
• 😥

The documentation search not working https://docs.minaprotocol.com/zkapps/how-to-write-a-zkapp-ui

Maybe it is now

[anandcsingh]

Fetching again taking too long, guess it is just the first time it is loaded in the browser, but devs need to know that to expect it otherwise they may go down some rabbit holes

[anandcsingh]

Tried pass around the smart contract function so that it could be invoked dynamically Call bjj vs judo based on condition Got a null exception I believe when executing the transaction
