Implementations§

Source§

impl<'a, ConvertAssetId, Call> XcmConverter<'a, ConvertAssetId, Call>
where ConvertAssetId: MaybeConvert<TokenId, Location>,

Source

pub fn new(message: &'a Xcm<Call>, ethereum_network: NetworkId) -> Self

Source

pub fn convert(&mut self) -> Result<Message, XcmConverterError>

Convert the XCM into an outbound message which can be dispatched to the Gateway contract on Ethereum

Assets being transferred can either be Polkadot-native assets (PNA) or Ethereum-native assets (ENA).

The XCM is evaluated in Ethereum context.

Expected Input Syntax:

ⓘ
WithdrawAsset(ETH)
PayFees(ETH)
ReserveAssetDeposited(PNA) | WithdrawAsset(ENA)
AliasOrigin(Origin)
DepositAsset(Asset)
Transact() [OPTIONAL]
SetTopic(Topic)

Notes: a. Fee asset will be checked and currently only Ether is allowed b. For a specific transfer, either ReserveAssetDeposited or WithdrawAsset should be present c. ReserveAssetDeposited and WithdrawAsset can also be present in any order within the same message d. Currently, teleport asset is not allowed, transfer types other than above will cause the conversion to fail e. Currently, AliasOrigin is always required, can distinguish the V2 process from V1. it’s required also for dispatching transact from that specific origin. f. SetTopic is required for tracing the message all the way along.
