Connect with WalletConnect

Before you can create a payment system or send any transaction you need to connect with the web3-provider. For that reason we made it as easy as possible to connect over the Palindrome SDK with Metamask or TrustWallet on mobile.

connectMetamask

Call the connectWalletConnect(args) function to connect with Metamask or TrustWallet. ThePalindrome Crypto Pay is supporting multiple chains such as AVAX, Ethereum & BSC. Therefore, you need to pass the chainID or rpc with the chaindID so that thePalindrome Crypto Pay Crypto SDK can recognize the chain you want to work with.

Import Functions

In the first step you need to import thePalindrome Crypto Pay SDK into your JavaScript/TypeScript project with the needed function PalindromePayConnect.

import { PalindromePayConnect } from '@Palindromepay/sdk'

Interfaces

// Input
export interface IConnect {
  rpc?: { [chainId: number]: string }; // optional
  chainId: number;
}

// Output
export interface IAuthInstance {
  account: string;
  provider: any;
  signer: any;
}

Function
