## Swap Transaction Finality

Swap transaction finality is the point at which a cross-chain exchange becomes irreversible and the assets are securely transferred to the recipient. Achieving finality is complex because it requires synchronization between the consensus mechanisms of two different blockchains.

If one chain has a shorter finality time than the other, the transaction may be at risk of reorganization or reversal on the slower chain. Protocols must implement robust verification steps to ensure that the swap is finalized on both sides before the funds are released.

Inadequate finality checks can lead to double-spending or the loss of assets during the swap process. This is particularly important for high-value transactions where the cost of a potential reversal is significant.

Finality is a cornerstone of reliable financial transactions and is essential for the growth of decentralized derivative markets.
