Used WalletNames's

type WalletNames = 'metamask' | 'coinbase' | 'imtoken' | 'math_wallet' | 'token_pocket' | 'wallet_connect' | ' bitkeep' | 'coin98'

const wallet = new Web3Wallets('metamask')
const accounts = await wallet.enable()
const res = await wallet.request({"method": "eth_blockNumber", "params": []})

Detect Wallets

const wallets = detectWallets()
const walletList = Object.values(wallets)

Get Provider

export interface WalletInfo {
    chainId: number
    address: string
    privateKeys?: string[]
    rpcUrl?: RpcInfo
    port?: number
    cacheExpiration?: number
    bridge?: string
    offsetGasLimitRatio?: number
    isSetGasPrice?: boolean
}

const {address, chainId, rpcUrl, walletSigner, walletProvider} = getProvider(walletInfo)

const zeroHash = getEIP712DomainHash(DOMAIN_DEFAULT)
const zero = "0xc92fa40dbe33b59738624b1b4ec40b30ff52e4da223f68018a7e0667ffc0e798"

RPC

    const response = await fetchJson(url, {timeout: 10000, proxyUrl: 'http://127.0.0.1:7890'})
    if (response.ok) {
        console.log(await response.json())
    } else {
