How to setup development

Run Rell code

1. chr install should installed FT4 into src/lib/ft4
2. create a file .chroma/chasm-test with this test key

privkey=0101010101010101010101010101010101010101010101010101010101010101
pubkey=031b84c5567b126440995d3ed5aaba0565d71e1834604819ff9c17f5e9d5dd078f

3. Update variables

Update pubkey in development.rell

object owner {
    mutable address: pubkey = x"031b84c5567b126440995d3ed5aaba0565d71e1834604819ff9c17f5e9d5dd078f";
}

In main.rell Update the line

// FROM
import production.{owner};
// TO
import development.{owner};

Update chromia.yml

blockchains:
  prompt:
    module: development

4. chr build to ensure build has no issue
5. chr test

Test out client

Before running the script, make sure the local client is up.

chr node start
# if needed to wipe db
chr node start --wipe
# Can update code via update command
chr node update

Nodejs

bun i
bun run nodejs

Python

Chromia does not have official python client, so we are using the Postchain API.

python script/query_data.py # bun run python

Production

Make sure setup ~/.chroma/config with private key at ~/.chroma/chasm-production

key.id = chasm-production

# Deployment
chr deployment create --settings chromia.yml --network mainnet --blockchain prompt                                                                                       
# Update
chr deployment update --network mainnet
