Asset registration and closuse

General

Hi,

Let’s assume a user registers for an asset (sending himself a 0 amount transfer). Then he transfer all his fund using the close operation.

Do he need to re-register to receive that type of asset again right?

Regards,
Mauro.

Hello @mxmauro

Yes. Let’s explore in more detail.

An account $RECEIVER desiring to hold an ASA $ID must first perform an opt-in transaction:

goal asset send --sign --out asset-send-opt-in.stxn --amount 0 --assetid $ID --from $RECEIVER --to $RECEIVER --datadir $DATA
goal clerk rawsend --filename asset-send-opt-in.stxn -d $DATA

Next, $SENDER will send an amount $AMOUNT of ASA to $RECEIVER

goal asset send -s -o asset-send-to-receiver.stxn -a $AMOUNT --assetid $ID -f $SENDER -t $RECEIVER -d $DATA
goal clerk rawsend -f asset-send-to-receiver.stxn -d $DATA

At this point, $RECEIVER has a balance of ASA

goal account list -d $DATA

$RECEIVER may send all of the ASA back to $RECEIVER

goal asset send -s -o asset-send-return-to-sender.stxn -a $AMOUNT --assetid $ID -f $RECEIVER -t $SENDER -d $DATA
goal clerk rawsend -f asset-send-return-to-sender.stxn -d $DATA

Checking the account balance again will indicate a zero-balance of the ASA for $RECEIVER

goal account list -d $DATA

$SENDER may again send the ASA to $RECEIVER at this time

goal asset send -s -o asset-send-to-receiver.stxn -a $AMOUNT --assetid $ID -f $SENDER -t $RECEIVER -d $DATA
goal clerk rawsend -f asset-send-to-receiver.stxn -d $DATA

This time, use the close-to flag to send all of the indicated ASA back to $SENDER and remove the ability for $RECEIVER to hold this asset (until a future opt-in transaction)

goal asset send -s -o asset-send-return-to-sender-and-close.stxn -a $AMOUNT --assetid $ID -f $RECEIVER -t $SENDER --close-to $SENDER -d $DATA
goal clerk rawsend -f asset-send-return-to-sender-and-close.stxn -d $DATA

Checking the account balance again will not indicate the ASA association for $RECEIVER and will require an opt-in transaction to receive this ASA in the future.

goal account list -d $DATA
