-The `"type": "axfer"` distinguishes this as an asset transfer transaction. The fields used in the transaction are the same as any other asset transfer. What distinguishes it as an opt-in transaction is in how those fields are specified and the sender account's asset holdings state prior to sending the transaction. In particular, the address `"QC7XT7...` is both the [sender](../../reference/transactions.md#sender) and [asset receiver](../../reference/transactions.md#assetreceiver) and it is assumed that the sender does not yet possess any of the desired asset identified with the [asset ID](../../reference/transactions.md#xferasset) `168103`. The asset amount is not specified in this example, which is equivalent to adding an [asset amount](../../reference/transactions.md#assetreceiver) equal to 0 (`"aamt": 0`). This transaction is valid on TestNet between rounds 6631154 and 6632154.
