Access the Contract State within the Notary

Question

I want to trigger a transaction in an External network from the Notary Service Flow just before consuming the Input State. The example is a Custodian service that triggers the notification to the Depository: Custodian on Corda & Depository on Hedera Hashgraph.

But the Notary flow does not have access to read the attributes from the Contract State. Is there a way to send/broadcast custom attributes to the Notary?

Thank you in advance.

Answer 1

If you setup your notary as a validating one; it will have access to all of the transaction components (read here).

To setup your notary as validating; set the below configuration inside its node.conf (taken from this sample):

notary {
    validating = true
}
