Build & Connect
This part of documentation is targeted to applications that want to implement nightly connect as wallet interface.
To get started, we need to connect the user to the application. In order to do so, application generates the sessionId, a unique id that identifies each connection.
This process is initialized by one side displaying a sessionId through QR code (see the screenshot). The other peer needs just to scan the QR code on its device. Extension wallets are auto detected so you are always up to date and don't need to upgrade your dapp.
Connect
Application builds a connection using build()
or buildLazy()
function that returns interface to communicated with remote user. It is important to note, that the buildLazy()
function allows for the modal to appear even when the sessionId is still undefined. App should define AppMetadata
so wallets will be able to show it to user.
To start sending request like signTransaction
user first need to connect to session.
Once user establishes connection, application will get public key and the connection will be confirmed.
API of application client is fit to match currently existing standards of corresponding blockchains
interface AppMetadata {
name: string;
url?: string;
description?: string;
icon?: string; // Url of app image
additionalInfo?: string;
}
You may also want to specify some additional connection options. This can be achieved by creating an object that implements the below interface, and using it inside the build()
or buildLazy()
function. Note, that the disableModal
property can be used for implementing a custom External modal.
interface ConnectionOptions {
disableModal?: boolean // default: false
// Used for disabling modal in case you want to use your own
initOnConnect?: boolean // default: false
// Ensures that the app is only build upon running the connect function
disableEagerConnect?: boolean // default: false
// Do not connect eagerly, even if the previous session is saved
}
import { NightlyConnectAptosAdapter } from '@nightlylabs/wallet-selector-aptos'
const adapter = await NightlyConnectAptosAdapter.build(
{
appMetadata: {
name: 'Movement Template',
description: 'Movement Template',
icon: 'https://docs.nightly.app/img/logo.png'
}
// persistent: false - Add this if you want to make the session non-persistent
}
// { initOnConnect: true, disableModal: true, disableEagerConnect: true } - You may specify the connection options object here
// document.getElementById("modalAnchor") , - You can pass an optional anchor element for the modal here
{
networkDataOverride: { // it is used to change the metadata of the NC Modal's network tab
name: 'Movement',
icon: 'https://registry.nightly.app/networks/movement.svg'
}
}
)
// Trigger connection
await adapter.connect()
// After connection adapter turns into remote signer
// Sign transaction
await adapter.signAndSubmitTransaction(transaction)
// Disconnect client if you want to end session
await adapter.disconnect()
Disconnect
Both client and application can initiate disconnection. User can force session termination in case of abuse. Only when application disconnects and session is not persistent, session is completely removed.
