Web3Wallet SDK

This spec has moved to WalletConnect Docs

Multi-chain provider would require primarly two main methods to interface with a multi-chain cryptocurrency wallet: enable and request.

Enable method would translate the same JSON-RPC parameters of CAIP-25 as Javascript arguments

	import React from "react";
	import * as uuid from 'uuid';

	import { WindowProvider } from "@wagmi/connectors"

	import defaultProviderIcon from "../assets/defaultProviderIcon.png"

	function getInjectedName(ethereum?: WindowProvider) {
	if (!ethereum) return 'Injected'

	// Our RPC id's are expected to be the same "length"
	// generating id's should use Unix epoch timestamp in miliseconds and append 3 random digits
	// currently Kotlin SDK has at least 3 more digits than all other SDKs
	// yet while Kotlin is the minority, it's preferable to increase integers than decrease them
	// this way we can keep backwards-compatibility for Kotlin clients in older releases
	// thus we could also increase entropy by also increasing other SDKs to 6 random digits

	function payloadId() {
	const date = Date.now() * Math.pow(10, 6);
	const extra = Math.ceil(Math.random() * Math.pow(10, 6));

	// Currently our proposals require a lot from wallets by including all methods into requiredNamespaces
	// This puts a high requirement on the wallets to support a lot of methods and chains

	{
	requiredNamespaces: {
	eip155: {
	chains: [1, 2, 3],
	methods: [
	'eth_sendTransaction',
	'eth_sendRawTransaction',
