Before a new asset can be received by a specific account in your Pera Wallet (such as rewards), you, as the receiver, need to opt-in to receive that asset. This ensures that your account only receives the assets you actively engage with.
An opt-in transaction involves transferring the asset with a value of 0 to the account opting in, which also increases the account's minimum balance by 100,000 microAlgos.
If you sign up for the UrbanChange mobile app using the Pera Wallet connection, you are prompted to opt-in to the "Resident" asset, which whitelists your account, and to your community's specific asset (e.g., "LocalCoin") to enable your account to receive the corresponding asset.
If you are a business owner using a Pera Wallet account and already applied to get your business on the app, you will be asked to opt-in to the "Business" asset to whitelist your business account with UrbanChange. This will automatically publish your business profile in the app and will make your business viewable - meaning users of the app will now be able to discover your business and spend their LocalCoins at your place!
*Opt-in to assets is needed only for those who choose to use the Pera Wallet connection method and is a one-time action. Once you have completed the opt-in process, you do not need to repeat it unless there are specific changes or updates related to the assets in the future.
