1.DAPP实现Metamask自动添加网络/切换网络:

实现方法调用matamask的wallet_switchEthereumChain方法

    async addNetwork() {// console.log("当前链接的节点为:", getInjectedProviderName())if (getInjectedProviderName() !== "MetaMask") {throw "This Network is Error";}let chain_info = ChainInfo[ChainId];try {await this.web3.currentProvider.request({method: 'wallet_switchEthereumChain',params: [{ chainId: this.web3.utils.numberToHex(chain_info.chainId), }],});} catch (switchError: any) {// This error code indicates that the chain has not been added to MetaMask.if (switchError.code === 4902) {await this.web3.currentProvider.request({method: 'wallet_addEthereumChain',params: [{chainId: this.web3.utils.numberToHex(chain_info.chainId),chainName: chain_info.chainParams.chainName,rpcUrls: chain_info.chainParams.rpcUrls,blockExplorerUrls: chain_info.chainParams.blockExplorerUrls,nativeCurrency: chain_info.chainParams.nativeCurrency},],});}}}

2.常用的Metamask网络列表

下面为常用的网络列表和区块浏览器地址:

 const CHAIN_DATA_LIST = {1: {chainId: 1,chain: "ETH",network: "mainnet",networkId: 1,chainParams: {chainName: "Ethereum Chain Mainnet", // 添加到钱包后显示的网络名称rpcUrls: ['https://mainnet.infura.io/v3/', // rpc地址],// iconUrls: [//     'https://testnet.hecoinfo.com/favicon.png' // 网络的图标// ],blockExplorerUrls: ['https://etherscan.io' // 网络对应的区块浏览器],nativeCurrency: {  // 网络主币的信息name: 'ETH',symbol: 'ETH',decimals: 18}}},2: {chainId: 2,chain: "EXP",network: "expanse",networkId: 1},3: {chainId: 3,chain: "ETH",network: "ropsten",networkId: 3,chainParams: {chainName: "Ethereum Chain Ropsten",rpcUrls: ['https://ropsten.infura.io/',  ],blockExplorerUrls: ['https://ropsten.etherscan.io'],nativeCurrency: {name: 'RopstenETH',symbol: 'RopstenETH',decimals: 18}}},4: {chainId: 4,chain: "ETH",network: "rinkeby",networkId: 4,chainParams: {chainName: "Ethereum Chain Rinkeby",rpcUrls: ['https://rinkeby.infura.io/v3/',],blockExplorerUrls: ['https://rinkeby.etherscan.io'],nativeCurrency: {name: 'RinkebyETH',symbol: 'RinkebyETH',decimals: 18}}},5: {chainId: 5,chain: "ETH",network: "goerli",networkId: 5,chainParams: {chainName: "Ethereum Chain Goerli",rpcUrls: ['https://goerli.infura.io/v3/',],blockExplorerUrls: ['https://goerli.etherscan.io'],nativeCurrency: {name: 'GoerliETH',symbol: 'GoerliETH',decimals: 18}}},6: {chainId: 6,chain: "ETC",network: "kotti",networkId: 6},8: {chainId: 8,chain: "UBQ",network: "ubiq",networkId: 88},9: {chainId: 9,chain: "UBQ",network: "ubiq-testnet",networkId: 2},11: {chainId: 11,chain: "META",network: "metadium",networkId: 11},12: {chainId: 12,chain: "META",network: "metadium-testnet",networkId: 12},18: {chainId: 18,chain: "TST",network: "thundercore-testnet",networkId: 18},30: {chainId: 30,chain: "RSK",network: "rsk",networkId: 30},31: {chainId: 31,chain: "RSK",network: "rsk-testnet",networkId: 31},42: {chainId: 42,chain: "ETH",network: "kovan",networkId: 42},56: {chainId: 56,chain: "BSC",network: "binance",networkId: 56,chainParams: {chainName: "Binance Smart Chain Mainnet", // 添加到钱包后显示的网络名称rpcUrls: ['https://bsc-dataseed.binance.org/', // rpc地址],blockExplorerUrls: ['https://bscscan.com' // 网络对应的区块浏览器],nativeCurrency: {  // 网络主币的信息name: 'BNB',symbol: 'BNB',decimals: 18}}},60: {chainId: 60,chain: "GO",network: "gochain",networkId: 60},61: {chainId: 61,chain: "ETC",network: "etc",networkId: 1},62: {chainId: 62,chain: "ETC",network: "etc-morden",networkId: 2},63: {chainId: 63,chain: "ETC",network: "etc-testnet",networkId: 7},64: {chainId: 64,chain: "ELLA",network: "ellaism",networkId: 64},76: {chainId: 76,chain: "MIX",network: "mix",networkId: 76},77: {chainId: 77,chain: "POA",network: "poa-sokol",networkId: 77},88: {chainId: 88,chain: "TOMO",network: "tomochain",networkId: 88},97: {chainId: 97,chain: "BSCT",network: "binance-test",networkId: 97},99: {chainId: 99,chain: "POA",network: "poa-core",networkId: 99},100: {chainId: 100,chain: "XDAI",network: "xdai",networkId: 100},101: {chainId: 101,chain: "ETI",network: "etherinc",networkId: 1},108: {chainId: 108,chain: "TT",network: "thundercore",networkId: 108},162: {chainId: 162,chain: "PHT",network: "sirius",networkId: 162},163: {chainId: 163,chain: "PHT",network: "lightstreams",networkId: 163},211: {chainId: 211,chain: "FTN",network: "freight",networkId: 0},269: {chainId: 269,chain: "HPB",network: "hpb",networkId: 100},385: {chainId: 385,chain: "CRO",network: "lisinski",networkId: 385},820: {chainId: 820,chain: "CLO",network: "callisto",networkId: 1},821: {chainId: 821,chain: "CLO",network: "callisto-testnet",networkId: 2},137: {chainId: 137,chain: "MATIC",network: "matic",networkId: 137},80001: {chainId: 80001,chain: "MUMBAI",network: "mumbai",networkId: 80001},246529: {chainId: 246529,chain: "ARTIS sigma1",network: "artis-s1",networkId: 246529},246785: {chainId: 246785,chain: "ARTIS tau1",network: "artis-t1",networkId: 246785}
};
