Clicking the AlgoOpt button will assemble an app opt-in transaction and open a new window prompting the user to confirm the transaction.


The rendered AlgoOpt button below is nonfunctional. To see it in action, check out the Component Demo!


The AlgoOpt button executes transactions on the MainNet by default. To switch to TestNet, check out SwitchNet Component

Upon confirmation, it returns the transaction id to the context and key specified. Failing to include to correct object parameters, or setting them incorrectly will result in a transaction not executing.

Accessing returned transaction id

The returned id can be accessed several different ways. Setting the context prop to {this} and the returnTo prop to a state key (as string) will return the number directly to your parent component's state without the need for additional callback or event handler code, but can also be accessed with an onChange handler:

handleChange = (value) =>{
this.setState({txId: value})
