@substrate/txwrapper-registry

Registry creation support, catering to chains with types in @polkadot/apps-config

``bash
yarn add @substrate/txwrapper-registry
`

In a JS/TS index file of package:

`typescript
import { getRegistry } from '@substrate/txwrapper-registry';

// Create Polkadot's type registry.
const registry = getRegistry({
chainName: 'Polkadot',
specName: 'polkadot',
specVersion: 26,
metadataRpc,
});
`

Have a look at the examples to see how getRegistry is used in the whole lifecycle of a transaction, from generation to signing to broadcast.

Config

In order to instantiate a registry with your chains custom types you must pass in the path to your own types bundle file. If you would like to generate a types bundle file and don't know how to, feel free to use this helper library we have created to generate these types. generate-type-bundle.

The following env variable is accepted:

TX_TYPES_BUNDLE=/path-to-file - Note: It must be a valid JSON file that has the same structure as the OverrideBundleTypes` in polkadot-js.
