impl<T: Config> Pallet<T>

pub fn transfer(
 origin: OriginFor<T>,
 currency_id: T::CurrencyId,
 amount: T::Balance,
 dest: Box<VersionedMultiLocation>,
 dest_weight: Weight
) -> DispatchResult

Transfer native currencies.

dest_weight is the weight for XCM execution on the dest chain, and it would be charged from the transferred assets. If set below requirements, the execution may fail and assets wouldn’t be received.

It’s a no-op if any error on local XCM execution or message sending. Note sending assets out per se doesn’t guarantee they would be received. Receiving depends on if the XCM message could be delivered by the network, and if the receiving chain would handle messages correctly.

pub fn transfer_multiasset(
 origin: OriginFor<T>,
 asset: Box<VersionedMultiAsset>,
 dest: Box<VersionedMultiLocation>,
 dest_weight: Weight
) -> DispatchResult

Transfer MultiAsset.

dest_weight is the weight for XCM execution on the dest chain, and it would be charged from the transferred assets. If set below requirements, the execution may fail and assets wouldn’t be received.

It’s a no-op if any error on local XCM execution or message sending. Note sending assets out per se doesn’t guarantee they would be received. Receiving depends on if the XCM message could be delivered by the network, and if the receiving chain would handle messages correctly.

pub fn transfer_with_fee(
 origin: OriginFor<T>,
 currency_id: T::CurrencyId,
 amount: T::Balance,
 fee: T::Balance,
 dest: Box<VersionedMultiLocation>,
 dest_weight: Weight
) -> DispatchResult

Transfer native currencies specifying the fee and amount as separate.

dest_weight is the weight for XCM execution on the dest chain, and it would be charged from the transferred assets. If set below requirements, the execution may fail and assets wouldn’t be received.

fee is the amount to be spent to pay for execution in destination chain. Both fee and amount will be subtracted form the callers balance.

If fee is not high enough to cover for the execution costs in the destination chain, then the assets will be trapped in the destination chain

It’s a no-op if any error on local XCM execution or message sending. Note sending assets out per se doesn’t guarantee they would be received. Receiving depends on if the XCM message could be delivered by the network, and if the receiving chain would handle messages correctly.

pub fn transfer_multiasset_with_fee(
 origin: OriginFor<T>,
 asset: Box<VersionedMultiAsset>,
 fee: Box<VersionedMultiAsset>,
 dest: Box<VersionedMultiLocation>,
 dest_weight: Weight
) -> DispatchResult

Transfer MultiAsset specifying the fee and amount as separate.

dest_weight is the weight for XCM execution on the dest chain, and it would be charged from the transferred assets. If set below requirements, the execution may fail and assets wouldn’t be received.

fee is the multiasset to be spent to pay for execution in destination chain. Both fee and amount will be subtracted form the callers balance For now we only accept fee and asset having the same MultiLocation id.

If fee is not high enough to cover for the execution costs in the destination chain, then the assets will be trapped in the destination chain

It’s a no-op if any error on local XCM execution or message sending. Note sending assets out per se doesn’t guarantee they would be received. Receiving depends on if the XCM message could be delivered by the network, and if the receiving chain would handle messages correctly.

pub fn transfer_multicurrencies(
 origin: OriginFor<T>,
 currencies: Vec<(T::CurrencyId, T::Balance)>,
 fee_item: u32,
 dest: Box<VersionedMultiLocation>,
 dest_weight: Weight
) -> DispatchResult

Transfer several currencies specifying the item to be used as fee

dest_weight is the weight for XCM execution on the dest chain, and it would be charged from the transferred assets. If set below requirements, the execution may fail and assets wouldn’t be received.

fee_item is index of the currencies tuple that we want to use for payment

It’s a no-op if any error on local XCM execution or message sending. Note sending assets out per se doesn’t guarantee they would be received. Receiving depends on if the XCM message could be delivered by the network, and if the receiving chain would handle messages correctly.

pub fn transfer_multiassets(
 origin: OriginFor<T>,
 assets: Box<VersionedMultiAssets>,
 fee_item: u32,
 dest: Box<VersionedMultiLocation>,
 dest_weight: Weight
) -> DispatchResult

Transfer several MultiAsset specifying the item to be used as fee

dest_weight is the weight for XCM execution on the dest chain, and it would be charged from the transferred assets. If set below requirements, the execution may fail and assets wouldn’t be received.

fee_item is index of the MultiAssets that we want to use for payment
