This is a noop if it’s already enabled Callable by the admin origin
Disables XCM transactions for the statemint parachain, if configured.
This is a noop if it’s already disabled Callable by the admin origin
Sets the statemint config.
Callable by the admin origin
NOTE It is assumed that the PINT parachain’s local account on
the statemint parachain (sibling account:
polkadot_parachain::primitives::Sibling) has the permission to
modify the statemint PINT asset.
Attempts to transfer the given amount of index token to statemint.
This is executed as reserve based transfer, the given amount is transferred from the sender’s balance to the account designated for the Statemint parachain. This amount is then send via XCM into the caller’s account on the statemint parachain.
Sends an XCM bond_extra call
Sends an XCM unbond call
An unbond call must be signed by the controller account.
Sends an XCM withdraw_unbonded call
Remove any unlocked chunks from the unlocking queue.
An withdraw_unbonded call must be signed by the controller
account.
This essentially gives the PINT’s reserve account hold of the balance

The ledger of deposited funds and funds about to be withdrawn
This mirrors the deposited and withdrawn amounts from the asset index until
Separating this from the MultiCurrency balances, which is used to represent any kind of
funds (for example assets minted via governance proposal), ensures that this the real inflow
of reserve backed assets.
NOTE: This expects the deposited funds to be backed by reserve deposits on the assets
native location. For DOT for example this expects the deposited funds to be available on
the Polkadot relay chain in the sovereign account of the PINT parachain.

Returns the current storage version as supported by the pallet.
Returns the on-chain storage version of the pallet as stored in the storage.
Check for staking related XCM we need to get in to this block
This will compare the pending withdrawals against the free balance of each asset and determine whether an XCM unbond, bond_extra or withdrawal is in order.
Executing XCM on another chain is subject to fees that will be paid for with the balance which is under control of the PINT’s account on that chain (the reserve held for all xcm deposits sent to PINT), therefore it is feasible that a certain amount of each asset is kept idle (not staked) at all times to mitigate the risk of lacking founds for the fees for unstaking. This reserve balance has fixed lower barrier and an additional buffer which reflects the NAV_asset of the asset in relation to the NAV of the index, since the amount of on asset a LP receives upon redeeming their PINT directly correlates with the value of each asset.
If an asset’s chain supports staking (it was previously bonded with
pallet_staking::bond) then we need to check what action is appropriate in this for
this asset’s staking pallet. Following states exists:
Idle: nothing to bond_extra, unbond or withdrawBondExtra: new deposits were added to the PINT’s parachain balance sheet and can now be bonded. This will also check if currently unbonded funds can be rebonded again instead.Unbond: pending withdrawals reached a threshold were we need to unbund staked funds.Withdraw: The bonding duration of an unlocking chunk is over and the funds are now safe to withdraw viawithdraw_unbonded
The maximum number of separate xcm calls we send here is limited to the number of liquid assets with staking support.
