Variants

transfer

Transfer native currencies.

dest_weight_limit 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.

Fields

currency_id: T::CurrencyId

amount: T::Balance

dest: Box<VersionedLocation>

dest_weight_limit: WeightLimit

transfer_multiasset

Transfer Asset.

dest_weight_limit 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.

Fields

asset: Box<VersionedAsset>

dest: Box<VersionedLocation>

dest_weight_limit: WeightLimit

transfer_with_fee

Transfer native currencies specifying the fee and amount as separate.

dest_weight_limit 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.

Fields

currency_id: T::CurrencyId

amount: T::Balance

fee: T::Balance

dest: Box<VersionedLocation>

dest_weight_limit: WeightLimit

transfer_multiasset_with_fee

Transfer Asset specifying the fee and amount as separate.

dest_weight_limit 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 Asset 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 Location 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.

Fields

transfer_multicurrencies

Transfer several currencies specifying the item to be used as fee

dest_weight_limit 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.

Fields

currencies: Vec<(T::CurrencyId, T::Balance)>

fee_item: u32

dest: Box<VersionedLocation>

dest_weight_limit: WeightLimit

transfer_multiassets
