In the figure below, the order states are represented in a state-machine diagram, with the actions that trigger each state transition.
According to the DLN API, an order must be in one of these states:
Created
An order placed by a user on the DLN is pending fulfillment.
Fulfilled
The order on the destination chain has been completed by a solver. The full amount of the requested assets has been successfully transferred to the dstChainTokenOutRecipient
SentUnlock
After fulfilling the order, the solver initiates the unlock procedure on the destination chain. A cross-chain message is sent via DMP to unlock the input assets locked on the source chain.
ClaimedUnlock
The unlock process is finalized, and the solver receives the input assets. The affiliate fee is directed to the affiliateFeeRecipient on the source chain.
OrderCancelled
The dstChainOrderAuthorityAddress has started the cancellation process on the destination chain.
SentOrderCancel
A cross-chain message is sent via DMP from the destination to the source chain. It unlocks the input assets on the source chain to be claimed by the srcAllowedCancelBeneficiary.
ClaimedOrderCancel
The source chain input assets have been claimed by the srcAllowedCancelBeneficiary. The cancel procedure is finalized.
If an order is either in Fulfilled, SentUnlock, or ClaimedUnlock states, it can be displayed as fulfilled for the end-user.
