index/classes/BundlerTransport.md

The only current launchpad transport: typed-data signing plus /bundle.

Constructors

Constructor

new BundlerTransport(options): BundlerTransport

Create a bundler transport with an injectable requestor and socket.

Parameters

Parameter	Type	Description
options	{ bundleBaseUrl: string; bundleSocketFactory?: SocketFactory; httpRequestor?: HttpRequestor; launchpadBaseUrl: string; signer: LaunchpadSigner; socketFactory?: SocketFactory; walletAddress: string; }	-
options.bundleBaseUrl	string	-
options.bundleSocketFactory?	SocketFactory	The app's own bundler socket (its reconnect settings, its lifecycle): called once per wait(), the transport only adds its listener for the bundle's event and removes it when the wait ends; it never disconnects that socket. Takes precedence over socketFactory.
options.httpRequestor?	HttpRequestor	-
options.launchpadBaseUrl	string	-
options.signer	LaunchpadSigner	-
options.socketFactory?	SocketFactory	Opens a socket for one wait(); the transport disconnects it when the wait ends (default: a socket.io websocket to bundleBaseUrl).
options.walletAddress	string	-

Returns

BundlerTransport

Methods

attach()

attach(attachment): BundleSubmission

A submission for a bundle sent earlier (a page that persisted { bundleId, method, uniqueKey, tokenName } and reloaded): its wait() confirms exactly as a fresh submission's does (the bundle's socket event raced against the REST confirmation, which also answers for a bundle that settled before this call). Nothing is signed or sent until wait().

Parameters

Parameter	Type
attachment	BundleAttachment

Returns

BundleSubmission

Throws

LaunchpadSDKError INVALID_BUNDLE_ATTACHMENT (details.field): an empty bundleId or uniqueKey, a method the bundler does not accept, a CreateSale without its tokenName.

Example

const submission = transport.attach({ bundleId, method: 'BuyWithNative', uniqueKey });
const result = await submission.wait();

---

submit()

submit(request): Promise<BundleSubmission>

Sign and submit one allowlisted launchpad write to the bundler.

Parameters

Parameter	Type
request	LaunchpadWriteRequest

Returns

Promise<BundleSubmission>

Example

const submission = await transport.submit({ method: 'BuyWithNative', dto, stringsInstructions });
await submission.wait();
