# Ideas for integrating low code platform with Algorand!

A small comment:
We’re working on standardizing many aspects of Algorand:

Many of these “ARCs” are still in draft, some are only in PR.
For example ARC-5 to ARC-11 defines standards for interface with wallets, ARC-4 defines an ABI (that should make it simpler to have a UI component to make smart…

## When I submit a transaction what is the most efficient way to make sure it is settled on the blockchain?
You can make a rest call to the /v2/transactions/pending/{txid} endpoint with your transaction id.
There are methods on the SDK clients to make this easier, usually named something like waitForConfirmation(client, txid, rounds).
If confirmed-round is >0, the transaction has been settled, otherwise…

## Is it possible a malicious dApp creator collects a signed txn then send it to another dApp?
Your scenario indeed is possible.
A webapp can request any transaction to be signed to a user.
There is nothing at the wallet level that will check whether a given webapp is supposed to make a given transaction.
Therefore, users must be very careful when approving transactions and must read them …

## Best way to assess if application would be possible on Algorand
To complement @Maugli's response, there are many ways of managing the accounts of the users so they don’t have to deal with mnemonics and secret keys.

## AlgoExplorer API: Algorand Node API end-points will be limited
Hi,
I want to communicate to the developer community that AlgoExplorer API will limit access to [Algorand Node API](https://algoexplorer.io/api-dev/v2) only to those APIs that are not available on [Algorand Indexer API](https://algoexplorer.io/api-dev/indexer-v2).
This change does not mean that we are limiting functionality, but we want to structure queries to optimize the resources…

## Question about ASAs and Smart Contract restrictions
Yes, currently the only way to prevent any account (whether controlled by a smart contract or not) to receive any asset is to opt out of the asset.

## How to measure time inside a smart contract
Smart contracts are only executed when an application call is made.
They cannot be “scheduled”.
(To my knowledge, this is a limitation of all the main blockchains.)  
However, you can write the smart contract such that anyone can call it once every 30 days. Then you should have an external script …

## Is there a way to view the transactions that are waiting to be executed in the next block? Mempool?
Just to emphasize what @fabrice mentioned above - there is no guarantee that your node would see all the transactions which would go to the next (effective) block.
If the network is not congested, and your node has enough download bandwidth and you’re connected to relays that have seen the same set of transactions, your node may be able to view them.

## Why does Algorand need an API key
The API key is a way to control who has access to the node REST API.
Each request to the API comes with some CPU/disk/etc cost. Using a key allows the node operator to control who has access to the node.
