yarn add @axia-core/txwrapper-registry

In a JS/TS index file of package:

import { getRegistry } from '@axia-core/txwrapper-registry';

  // Create AXIA's type registry.
  const registry = getRegistry({
    chainName: 'AXIA',
    specName: 'axia',
    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.
