## Non-Repudiation Mechanisms

Non-repudiation is the assurance that the author of a statement or the sender of a transaction cannot successfully deny having sent it. In the domain of derivatives and digital assets, this is achieved through digital signatures that are cryptographically tied to the specific transaction data.

Once a transaction is signed and broadcast to the network, the mathematical proof makes it impossible for the sender to claim they did not authorize the movement of funds. This provides legal and operational certainty in automated trading environments where transactions are irreversible.

It acts as a digital guarantee that the intent of the participant is permanently recorded. This mechanism is essential for settling smart contract obligations without manual intervention.
