@totemsdk/realtime / MinimaRpcBackend

Class: MinimaRpcBackend

Plug-in interface for the portfolio data source.

Implement this to use any chain provider — LookupNode, a raw Minima RPC, a custom indexer — instead of the default Axia hosted API.

Examples​

— sovereign LookupNode

import { LookupBackend } from '@totemsdk/realtime';
import { connectLookupNode } from '@totemsdk/lookup-client';

const client = await connectLookupNode({ hyperswarmTopic: 'abc...' });
const manager = createPortfolioStreamManager(deps, {
  backend: new LookupBackend(client),
});

— direct Minima node (polling)

import { MinimaRpcBackend } from '@totemsdk/realtime';
import { createMinimaRpcClient } from '@totemsdk/minima-rpc';

const rpc = createMinimaRpcClient({ host: 'localhost', port: 9005 });
const manager = createPortfolioStreamManager(deps, {
  backend: new MinimaRpcBackend(rpc),
});
