I am looking for some Pyteal / AlgoSDK functions: The function writing the global states of specified external contracts. Currently, the function of App.globalPut in pyteal is only able to write global state inside the given contract. I think the functionality I am looking for looks like App.glob…

For security reasons, a smart contract can only modify its own state. Otherwise, you could bypass the logic of any other smart contract by creating your own smart contract. What you can do however, is allowing creating a group of transactions with calls to multiple smart contracts. The smart contrac…

Thanks @fabrice for your reply. I think the function listing all opted accounts will be really helpful to my project. However, the app searching functions, like indexer.applications and indexer.search_application, do not return the results that I want. Is there any other function showing the opted…

Also, I have some questions about what you mentioned in your previous answer. “What you can do however, is allowing creating a group of transactions with calls to multiple smart contracts”. Here, what is creating a group of transaction means? Is that meaning making transactions modifying the global…

Regarding your question on transaction groups ( or transaction grouping ): A single transaction is trivial. It ensures that once the transaction is submitted and included in a block, the content of the transaction is applied. Transactions groups extends that to multiple transactions - it allows yo…

Hi fabrice and tsachi, thank you for your help! Our goal is to store many users’ information on Algorand. This can be achieved by asking users to opt in one app where we deploy our smart contract and use their local states as storage of individual user’s information. However, if anyone who wants to …

However, if anyone who wants to see information of all users opted in this app, it’s that possible to achieve this goal using the algosdk? Yes, this is possible. You can use the indexer for that purpose. See the REST call there: indexer - Algorand Developer Portal The SDKs support this call. H…

Thank fabrice for your reply. I am wondering about the function displaying all info about opted-in users. I believe there should be some functions of algoSDK wrapping the REST call you have mentioned. But, as far as I know, the indexer functions in algosdk, including indexer.account_info, indexer.a…

You need to use “Search Accounts”. See Algorand Developer Docs The second example filters by assetID. Just replace assetID by applicationID, and remove currencyGreaterThan. Concretely, in JS, something like: (async () => { let applicationID = 312769; let accountInfo = await indexerClien…

take a look at this example to see parsing individual state values for accounts opted into stateful smart contracts: smart-contracts/dex.js at master · algorand/smart-contracts · GitHub
