CIP34-JS

A JS library for CIP34 that defines chain IDs for Cardano.

Example

| Network name | CIP34 chain ID | | ------------- | ----------------- | | PreProduction | cip34:0-1 | | Mainnet | cip34:1-764824073 |

Usage

Generate chain ID from registry data

import { toChainId } from "@dcspark/cip34-js";
import registry from "@dcspark/cip34-js/registry";

const chainId = toChainId({
  networkId: registry.Mainnet.NetworkId,
  networkMagic: registry.Mainnet.NetworkMagic,
});

Get parts from chain ID

import { fromChainId } from "@dcspark/cip34-js";

const { networkId, networkMagic } = fromChainId(chainId);

Updating

The current status of the registry is tracked inside the CIP repository. To keep things in sync, this project uses the CIP repo as a git submodule.

To use the latest version of the registry,

1. git submodule init
2. git submodule update
3. (whenever you want to update afterwards) npm run update-submodule
