yarn dev

Building Before creating a production version of your app, install an adapter for your target environment. Then:

yarn build

After adding a list of networks in ./src/lib/config.ts, you have access to ethers providers for each network.

import { networkProviders: { [chainId: string]: providers.JsonRpcProvider } } from '$lib/stores/provider'

Methods to connect wallets

• connectMetamask - Connect Metamask or other injected wallets
• connectWalletConnect - Wallet Connect Connection
• and disconnect

Stores for the connection information are also provided

import {
    accountChainId,
    accountProvider,
    connected,
    walletAddress
} from '$lib/stores/provider'

• accountChainId - { chainId: number, supportedNetwork: boolean } supportedNetwork is true if you have provided configuration options for this network
• accountProvider - EIP-11933 compliant provider object. Generally used with ethers.providers.Web3Provider($accountProvider)
• connected - boolean
• walletAddress - Defaults to 0x0000000000000000000000000000000000000000 if not connected
