Invoicing CorDapp

This is the invoicing CorDapp solution built during the PSL hackathon

Problem Statement

This was built using the Kotlin version of the CorDapp template.

Pre-Requisites

See https://docs.corda.net/getting-set-up.html.

Usage

Running the nodes

See https://docs.corda.net/tutorial-cordapp.html#running-the-example-cordapp.

Extending the template

You should extend this template as follows:

• Add your own state and contract definitions under cordapp-contracts-states/src/main/kotlin/
• Add your own flow definitions under cordapp/src/main/kotlin/
• Extend or replace the client and webserver under clients/src/main/kotlin/

For a guided example of how to extend this template, see the Hello, World! tutorial here.

Testing this solution

• Run on Seller, Buyer nodes - Should show empty vaults

  run vaultQuery contractStateType: com.template.InvoiceState

• Run on Seller node

  flow start InvoiceIssueFlow buyer: "Buyer", amount: 500, status: "CREATED"

• Run on Seller, Buyer nodes - Should show invoice created with status "CREATED"

  run vaultQuery contractStateType: com.template.InvoiceState

• Run on Buyer node - (* Use the linear ID you got by running the query above)

  flow start InvoiceSettlementFlow linearIdentifier: 3d02ddfc-4056-42bb-beee-7ff723497748

• Run on Seller, Buyer nodes - Should show invoice created with status "SETTLED"

  run vaultQuery contractStateType: com.template.InvoiceState

TODOS

• Write tests for states, contracts, flows
