I have a reserved balance on my account of n DOT but I cannot remember what I did that would cause the amount to be reserved.
Is there a way that I can discover the reason for the reservation, and ultimately what I need to do to free up the reserved balance?
I must say, this is quite inconvenient.
Unlike the balance lock, there's no "reserve ID" available for this.
Ideally, a good pallet should keep a record of such transactions. For instance, when setting a proxy on the blockchain, the proxy pallet should store how many tokens were allocated for reservation in storage.
Previously, removing a pallet without releasing the reserved funds could permanently lock those tokens. Worse still, some problematic pallets failed to keep records; they relied solely on a runtime-configured dynamic formula (e.g. T::DepositAmount::get()), which could change with any runtime upgrade. If they forget to provide a migration, the funds will also be locked forever.
All these factors need to be taken into account.
If everything work as expected, the most accurate method is to check all pallets and determine their reservation storage.
Maybe you set an identity or a proxy ? As mentioned in the wiki these can be two possible reasons for your reserved funds. If that is the case, as soon as you clear the identity or remove a proxy, your funds will be unreserved/freed.
You could also use an explorer like Subscan to check the extrinsics related to your account. For example, if you check in the extrinsics list of this account you will find two calls alongside others :
identity (set_identity) andidentity (set_subs) callBy clicking on either of these extrinsics (22676473-2 or 22676503-2) to see the details (e.g. events triggered for set_subs) you will see a balances (Reserved) event, indicating some funds were reserved.
