Chainweaver Wallet Adapter Legacy

This package provides an adapter for the Chainweaver Legacy Wallet on Kadena. It extends a base adapter while preserving the "kadena_"‑prefixed methods expected by BaseWalletAdapter by mapping them to the Chainweaver local HTTP API.

Installation

npm install @kadena/wallet-adapter-chainweaver-legacy
# or
yarn add @kadena/wallet-adapter-chainweaver-legacy
# or
pmpm add @kadena/wallet-adapter-chainweaver-legacy

Factory Usage

The primary export is a factory function createChainweaverLegacyAdapter, which detects the Chainweaver provider and, if found, returns an adapter instance. If the Chainweaver provider is not available, detection returns null:

import { createChainweaverLegacyAdapter } from '@kadena/wallet-adapter-chainweaver-legacy';

(async () => {
  const adapterFactory = createChainweaverLegacyAdapter();
  const provider = await adapterFactory.detect();
  if (!provider) {
    console.log('Chainweaver Wallet not found.');
    return;
  }
  const adapter = await adapterFactory.adapter(provider);
  await adapter.connect();
  const account = await adapter.getActiveAccount();
  console.log('Connected account:', account);
})();

Manual Usage of the Adapter or Detection

For lower-level access, the following exports are available:

• ChainweaverLegacyAdapter: The adapter class you can instantiate directly.
• detectChainweaverLegacyProvider: A standalone function that checks whether the Chainweaver wallet provider is present. It returns the provider if found, or null otherwise.

import {
  ChainweaverLegacyAdapter,
  detectChainweaverLegacyProvider,
} from '@kadena/wallet-adapter-chainweaver-legacy';

(async () => {
  const provider = await detectChainweaverLegacyProvider({ silent: true });
  if (!provider) {
    console.log('Chainweaver Wallet not available.');
    return;
  }
  const adapter = new ChainweaverLegacyAdapter({ provider });
  await adapter.connect();
  console.log('Connected to Chainweaver directly!');
})();

Supported methods

| Method | KIP | Supported | | --------------------- | ----------- | --------- | | kadena_sign_v1 | [KIP-17][1] | Yes | | kadena_quicksign_v1 | [KIP-17][1] | Yes | | kadena_getAccount_v1 | [KIP-37][2] | No | | kadena_getAccounts_v2 | [KIP-38][3] | No | | kadena_getNetwork_v1 | [KIP-39][4] | No | | kadena_getNetworks_v1 | [KIP-40][5] | No |

Other Notes

• The adapter internally calls methods like kadena_sign_v1, and kadena_quicksign_v1, mapping them to Chainweaver’s local HTTP endpoints (e.g. http://127.0.0.1:9467/v1/sign and /v1/quicksign).
• If you support multiple wallets in your application, the lazy import in chainweaverAdapterLegacy helps reduce your initial bundle size by loading the Chainweaver adapter code only when the provider is detected.
• Ensure that the user has installed the Chainweaver wallet. If the wallet is not installed, detection will yield null.
