# unapplied\_transfers

Represents a crosschain transfer that has been unapplied.

A cross-chain transfer that is past its deadline must be recalled or canceled. After doing
so, `unapply_transfer` needs to be called on all chains where the transfer was applied before
reverting it on the starting chain.

For example, if a chain going A -> B -> C -> D got cancelled or recalled on chain D, it
must be unapplied on chain C, then on chain B, then reverted on chain A.
