});
console.log('Connected:', accounts[0]);

Add HyperPaxeer

await window.ethereum.request({
  method: 'wallet_addEthereumChain',
  params: [{
    chainId: '0xe5',
    chainName: 'HyperPaxeer',
    nativeCurrency: {
      name: 'HyperPaxeer',
      symbol: 'HPX',
      decimals: 18
    },
    rpcUrls: ['https://public-rpc.paxeer.app/rpc'],
    blockExplorerUrls: ['https://paxscan.io']
  }]
});

WalletConnect

WalletConnect

npm install @web3modal/wagmi wagmi viem

import { createWeb3Modal } from '@web3modal/wagmi/react'
import { walletConnect } from 'wagmi/connectors'

const projectId = 'YOUR_PROJECT_ID'

const modal = createWeb3Modal({
  wagmiConfig,
  projectId,
  chains: [paxeer]
})
