orderId is deterministic and uniquely identifies an order. To successfully fulfill the order, the solver must use the same parameters that were
specified when the order was originally created. After successful fulfillment, the solver creates another transaction to trigger a cross-chain message
via the deBridge Messaging Protocol (DMP) to the source chain changing the order
state to SentUnlock. This message unlocks the input reserve
assets, allowing the solver to claim them.
If any parameters, such as the token amount or beneficiary, differ from the original order, the resulting orderId will not match. In such cases,
the solver’s deposit cannot be matched to a valid order on the source chain, rendering the fulfillment ineffective and ensuring the input funds
remain locked and secure on the source chain.
To finalize the process, the solver calls the DlnSource.claimUnlock(...) method on the source chain. This updates the order status to
ClaimedUnlock, and the initially locked order input reserve assets are transferred to the solver. At this point, the order is considered
claimed and fulfilled and its state is ClaimedUnlock. Affiliate fees are also automatically paid out on EVM chains, and they are ready
for withdrawal on Solana.
