WalletConnect with telegram bot

[thanhnguyennguyen]

I have an idea to build a telegram bot which pair with user wallet via walletConnect to make on chain transaction via telegram
My intended workflow is

• User login their wallet using walletConnect (Telegram Bot will show an QR for them to scan and login)
• User type commands to make transaction
• TelegramBot makes an transaction and ask user Sign transaction via mobile wallet (supported WalletConnect)
• Broadcast transaction

However
AFAIK, WalletConnect is pairing with browser only
is there any solution to pair a wallet ( supported WalletConnect) with Telegram Bot (basically it' a nodeJS backend)

[glitch-txs]

You can try this with sign API or core API from a backend

[thanhnguyennguyen]

I'm installing this package in backend typescript and build failed

import { Core, Pairing, } from '@walletconnect/core'

so any solution to resolve above error

[rhlsthrm]

Don't use the core SDK, try something like this:

import AuthClient from "@walletconnect/auth-client";

const { topic, uri } = await authClient.core.pairing.create();
console.log("uri: ", uri);

I'm stuck on figuring out how to structure the URI into something that can be read by a wallet... I'm trying to also create a WalletConnect TG bot if you want to try to debug together @thanhnguyennguyen.

[thanhnguyennguyen]

yes, sure @rhlsthrm . I'm glad to hear that. let's debug together
I'm using typescript
Installed "@walletconnect/auth-client"

    "@influxdata/influxdb-client": "^1.33.2",
    "@walletconnect/auth-client": "^2.1.1",
    "axios": "^1.4.0",
    "config": "^3.3.9",
    "node-telegram-bot-api": "^0.61.0",
    "tslib": "~2.5",
    "winston": "^3.10.0"
  }

Still got same error

> tsc -p tsconfig.json

node_modules/@walletconnect/environment/dist/cjs/crypto.d.ts:1:44 - error TS2304: Cannot find name 'Crypto'.

Found 2 errors in the same file, starting at: node_modules/@walletconnect/environment/dist/cjs/crypto.d.ts:1

[rhlsthrm]

I didn't have this error, maybe it's a node version thing?

[thanhnguyennguyen]

im using node v16.16.0
which node version you are using ?

[grzyslaw]

Hey, did you guys made any progress regarding the integration? If so, would you please be so kind to share some insights?

[Ydev1992]

Hi, so do you have telegram bot that do wallet connect just like gateway?

[christopheSeeka]

Here's the handle for WalletConnect i guess.

[glitch-txs]

Hey everyone we are working on a nice solution for Telegram bots and MiniApps

[surfacing8671]

you are my hero. Also, if applicable or possible, getting this to work on the desktop version of tg as well.

[skhetcho]

I faced a similar issue, I noticed it has to do with the way Telegram handles deep links and opening urls. ConnectKit seems to bypass this issue when it comes to wallet connections. Although triggering transactions could happening within the tApp, you have to go to the wallet manually go into the wallet and approve the transaction as it does not open the wallet automatically

[boneylva]

Awesome, is there any new news?

[alanwu4321]

@glitch-txs Are we waiting for this PR to merge? Is there anything we can do in the meantime to help or work around? 😄
