Sui Wallet Standard

import { createNoderailsCardProvider, registerWallCardSuiWalletStandard } from "@wallcard/sdk-core";

const wallcard = createNoderailsCardProvider({ mode: "popup" });
// Default: auto-registers with Wallet Standard in browser
// Opt out: createNoderailsCardProvider({ registerSuiWalletStandard: false })
// Manual: registerWallCardSuiWalletStandard(wallcard);

const { sui } = wallcard.getLinkedAddresses();

Popup vs iframe

createNoderailsCardProvider({ mode: "popup" });   // default — separate window
createNoderailsCardProvider({ mode: "iframe" });  // in-page overlay
createNoderailsCardProvider({ mode: "auto" });    // prefer iframe when possible

All signing methods open user approval UI. Unsupported methods throw with Unsupported method.
