Experiments in using information from Contract Blueprints

This repo is investigating using contract blueprints specified in CIP-57: https://cips.cardano.org/cip/CIP-57.

Getting uplc from blueprint using aiken

Prerequisites: aiken

Generate the blueprint using:

aiken build 

The cbor hex code noted in the blueprint by the compiledCode field is then stored in the file helloWorld.cbor.

The uplc is generated from the compile code by running the following command:

aiken uplc decode helloWorld.cbor -c --hex >> helloWorld.uplc

Getting uplc from blueprint using HarmonicLabs uplc library

Prerequisites:

1. uplc from HarmonicLabs
2. npx

Add the desired cbor code to convert.ts then run:

npx ts-node convert.ts >> helloWorld.uplc

Note: The cbor hex file should start with the plutus compiler version when using convert.ts. In the case of the helloWorld example the original cbor is in the form:

587b010000323232... to use with the uplc library everything before the plutus compiler version which is 10000 should be removed e.g. 587b0 should be removed. See the following link for more discussion on this.
