// outgoing amount will actually be 1/10th of the source amount,
// i.e. `from_amount * (from_rate / to_rate)`
// Exchange rates are expressed as `base asset / asset`. To calculate the outgoing amount,
// we multiply by the incoming asset's rate and divide by the outgoing asset's rate. For example,
// if an incoming packet is denominated in an asset worth 1 USD and the outgoing asset is worth
// 10 USD, the outgoing amount will be 1/10th of the source amount.
