addLiquidity(asset1: StagingXcmV4Location, asset2: StagingXcmV4Location, amount1_desired: u128, amount2_desired: u128, amount1_min: u128, amount2_min: u128, mint_to: AccountId32)​

  • interface: api.tx.assetConversion.addLiquidity

  • summary: Provide liquidity into the pool of asset1 and asset2. NOTE: an optimal amount of asset1 and asset2 will be calculated and might be different than the provided amount1_desired/amount2_desired thus you should provide the min amount you're happy to provide. Params amount1_min/amount2_min represent that. mint_to will be sent the liquidity tokens that represent this share of the pool.

    NOTE: when encountering an incorrect exchange rate and non-withdrawable pool liquidity, batch an atomic call with [Pallet::add_liquidity] and [Pallet::swap_exact_tokens_for_tokens] or [Pallet::swap_tokens_for_exact_tokens] calls to render the liquidity withdrawable and rectify the exchange rate.

    Once liquidity is added, someone may successfully call [Pallet::swap_exact_tokens_for_tokens] successfully.

  • interface: api.tx.collatorSelection.setInvulnerables

  • summary: Set the list of invulnerable (fixed) collators. These collators must do some preparation, namely to have registered session keys.

    The call will remove any accounts that have not registered keys from the set. That is, it is non-atomic; the caller accepts all AccountIds passed in new individually as acceptable Invulnerables, and is not proposing a set of new Invulnerables.

    This call does not maintain mutual exclusivity of Invulnerables and Candidates. It is recommended to use a batch of add_invulnerable and remove_invulnerable instead. A batch_all can also be used to enforce atomicity. If any candidates are included in new, they should be removed with remove_invulnerable_candidate after execution.

    Must be called by the UpdateOrigin.

updateBond(new_deposit: u128)​

  • interface: api.tx.collatorSelection.updateBond

  • summary: Update the candidacy bond of collator candidate origin to a new amount new_deposit.

    Setting a new_deposit that is lower than the current deposit while origin is occupying a top-DesiredCandidates slot is not allowed.

    This call will fail if origin is not a collator candidate, the updated bond is lower than the minimum candidacy bond, and/or the amount cannot be reserved.

  • summary: Transfer some assets from the local chain to the destination chain through their local, destination or remote reserve, or through teleports.

    Fee payment on the destination side is made from the asset in the assets vector of index fee_asset_item (hence referred to as fees), up to enough to pay for weight_limit of weight. If more weight is needed than weight_limit, then the operation will fail and the sent assets may be at risk.

  • interface: api.tx.polkadotXcm.transferAssetsUsingTypeAndThen

  • summary: Transfer assets from the local chain to the destination chain using explicit transfer types for assets and fees.

    assets must have same reserve location or may be teleportable to dest. Caller must provide the assets_transfer_type to be used for assets:

    • TransferType::LocalReserve: transfer assets to sovereign account of destination chain and forward a notification XCM to dest to mint and deposit reserve-based assets to beneficiary.

    • TransferType::DestinationReserve: burn local assets and forward a notification to dest chain to withdraw the reserve assets from this chain's sovereign account and deposit them to beneficiary.

    • TransferType::RemoteReserve(reserve): burn local assets, forward XCM to reserve chain to move reserves from this chain's SA to dest chain's SA, and forward another XCM to dest to mint and deposit reserve-based assets to beneficiary. Typically the remote reserve is Asset Hub.

    • TransferType::Teleport: burn local assets and forward XCM to dest chain to mint/teleport assets and deposit them to beneficiary.

      On the destination chain, as well as any intermediary hops, BuyExecution is used to buy execution using transferred assets identified by remote_fees_id. Make sure enough of the specified remote_fees_id asset is included in the given list of assets. remote_fees_id should be enough to pay for weight_limit. If more weight is needed than weight_limit, then the operation will fail and the sent assets may be at risk.

      remote_fees_id may use different transfer type than rest of assets and can be specified through fees_transfer_type.

      The caller needs to specify what should happen to the transferred assets once they reach the dest chain. This is done through the custom_xcm_on_dest parameter, which contains the instructions to execute on dest as a final step. This is usually as simple as: Xcm(vec![DepositAsset { assets: Wild(AllCounted(assets.len())), beneficiary }]), but could be something more exotic like sending the assets even further.

    • origin: Must be capable of withdrawing the assets and executing XCM.

    • dest: Destination context for the assets. Will typically be [Parent, Parachain(..)] to send from parachain to parachain, or [Parachain(..)] to send from relay to parachain, or (parents: 2, (GlobalConsensus(..), ..)) to send from parachain across a bridge to another ecosystem destination.

    • assets: The assets to be withdrawn. This should include the assets used to pay the fee on the dest (and possibly reserve) chains.

    • assets_transfer_type: The XCM TransferType used to transfer the assets.

    • remote_fees_id: One of the included assets to be used to pay fees.

    • fees_transfer_type: The XCM TransferType used to transfer the fees assets.

    • custom_xcm_on_dest: The XCM to be executed on dest chain as the last step of the transfer, which also determines what happens to the assets on the destination chain.

    • weight_limit: The remote-side weight limit, if any, for the XCM fee purchase.

    • calls: The calls to be dispatched from the same origin. The number of call must not exceed the constant: batched_calls_limit (available in constant metadata).

      If origin is root then the calls are dispatched without checking origin filter. (This includes bypassing frame_system::Config::BaseCallFilter).

      Complexity​

    • O(C) where C is the number of calls to be batched.

      This will return Ok in all circumstances. To determine the success of the batch, an event is deposited. If a call failed and the batch was interrupted, then the BatchInterrupted event is deposited, along with the number of successful calls made and the error of the failed call. If all were successful, then the BatchCompleted event is deposited.

batchAll(calls: Vec<Call>)​

  • interface: api.tx.utility.batchAll

  • summary: Send a batch of dispatch calls and atomically execute them. The whole transaction will rollback and fail if any of the calls failed.

    May be called from any origin except None.

    • calls: The calls to be dispatched from the same origin. The number of call must not exceed the constant: batched_calls_limit (available in constant metadata).

      If origin is root then the calls are dispatched without checking origin filter. (This includes bypassing frame_system::Config::BaseCallFilter).

      Complexity​

    • O(C) where C is the number of calls to be batched.

forceBatch(calls: Vec<Call>)​

  • interface: api.tx.utility.forceBatch

  • summary: Send a batch of dispatch calls. Unlike batch, it allows errors and won't interrupt.

    May be called from any origin except None.

    • calls: The calls to be dispatched from the same origin. The number of call must not exceed the constant: batched_calls_limit (available in constant metadata).

      If origin is root then the calls are dispatch without checking origin filter. (This includes bypassing frame_system::Config::BaseCallFilter).

      Complexity​

    • O(C) where C is the number of calls to be batched.

withWeight(call: Call, weight: SpWeightsWeightV2Weight)​

  • interface: api.tx.utility.withWeight

  • summary: Dispatch a function call with a specified weight.

    This function does not check the weight of the call, and instead allows the Root origin to specify the weight of the call.

    The dispatch origin for this call must be Root.

      Complexity​

    • O(1).

mergeSchedules(schedule1_index: u32, schedule2_index: u32)​

  • interface: api.tx.vesting.mergeSchedules

  • summary: Merge two vesting schedules together, creating a new vesting schedule that unlocks over the highest possible start and end blocks. If both schedules have already started the current block will be used as the schedule start; with the caveat that if one schedule is finished by the current block, the other will be treated as the new merged schedule, unmodified.

    NOTE: If schedule1_index == schedule2_index this is a no-op. NOTE: This will unlock all schedules through the current block prior to merging. NOTE: If both schedules have ended by the current block, no new schedule will be created and both will be removed.

    Merged schedule attributes:

    • starting_block: MAX(schedule1.starting_block, scheduled2.starting_block, current_block).

    • ending_block: MAX(schedule1.ending_block, schedule2.ending_block).

    • locked: schedule1.locked_at(current_block) + schedule2.locked_at(current_block).
