Python SDK for TON Connect 2.0
Analogue of the @tonconnect/sdk library.
Use it to connect your app to TON wallets via TonConnect protocol. You can find more details and the protocol specification in the docs.
Install Python 3 package: pip3 install pytonconnect
App needs to have its manifest to pass meta information to the wallet. Manifest is a JSON file named as tonconnect-manifest.json following format:
{
"url": "<app-url>", // required
"name": "<app-name>", // required
"iconUrl": "<app-icon-url>", // required
"termsOfUseUrl": "<terms-of-use-url>", // optional
"privacyPolicyUrl": "<privacy-policy-url>" // optional
}Make sure that manifest is available to GET by its URL.
If user connected his wallet before, connector will restore the connection
import asyncio
from pytonconnect import TonConnect
async def main():
connector = TonConnect(manifest_url='https://raw.githubusercontent.com/XaBbl4/pytonconnect/main/pytonconnect-manifest.json')
is_connected = await connector.restore_connection()
print('is_connected:', is_connected)
if __name__ == '__main__':
asyncio.get_event_loop().run_until_complete(main())You can fetch all supported wallets list
wallets_list = connector.get_wallets()
# wallets_list is
# [
# {
# name: str,
# image: str,
# about_url: str,
# bridge_url: str,
# universal_url: str,
# },
# ]You also can get wallets list using get_wallets static method:
wallets_list = TonConnect.get_wallets()def status_changed(wallet_info):
# update state/reactive variables to show updates in the ui
print('wallet_info:', wallet_info)
unsubscribe()
unsubscribe = connector.on_status_change(status_changed)
# call unsubscribe() later to save resources when you don't need to listen for updates anymore.generated_url = await connector.connect(wallets_list[0])
print('generated_url:', generated_url)Then you have to show this link to user as QR-code, or use it as a deep_link. You will receive an update in connector.on_status_change when user approves connection in the wallet.
