Attestation

The processor uses an attestation to prove the validity of a settlement. It serves as a cryptographic proof that the fulfillment of a Safenet transaction is valid under the specific conditions defined by the user's configured guarantees.

The attestation has to be sent from the spend chain to the home chain, where it is validated by the guarantee engine. It is then sent from the guarantee engine to the settlement engine on the debit chain to finalize the settlement. The attestation data is sent through external bridges, which can be costly and slow.

The processor has to provide the attestation when a validator challenges a settlement. The processor can voluntarily provide the attestation with the settlement request to ensure the settlement is processed directly.
