    Class LumeraClient

    Main LumeraClient facade

    The primary entry point for the Lumera SDK, composing blockchain and storage operations into a unified interface. This client provides:

    • Blockchain: Full blockchain client (transactions and queries)
    • Cascade.uploader: File upload operations
    • Cascade.downloader: File download operations
    import { createLumeraClient } from "@lumera/sdk-js";
    import { DirectSecp256k1HdWallet } from "@cosmjs/proto-signing";

    // Create a wallet
    const wallet = await DirectSecp256k1HdWallet.fromMnemonic(mnemonic, {
      prefix: "lumera"
    });
    const [account] = await wallet.getAccounts();

    // Create the client using testnet preset
    const client = await createLumeraClient({
      preset: "testnet",
      signer: wallet,
      address: account.address
    });

    // Query blockchain
    const params = await client.Blockchain.Action.getParams();

    // Upload a file to Cascade
    const result = await client.Cascade.uploader.uploadFile(file, {
      actionId: "action-123",
      rq_ids_ic: 1000,
      rq_ids_max: params.rq_ids_max
    });

    // Download a file from Cascade
    const stream = await client.Cascade.downloader.download("action-456");
