通过 ethereum.request 发起切换主网请求,metamask小狐狸钱包,通过点击接受或同意切换请求,即可切换到对应主网,无需用户一点点设置填写主网信息
function switch_network(network){ const bsc = { chainId: '0x38', // 币安主网的chainId是56 chainName: 'Smart Chain', nativeCurrency: { name: 'BNB', symbol: 'bnb', decimals: 18, }, rpcUrls: ['https://bsc-dataseed.binance.org/'], blockExplorerUrls: ['https://bscscan.com/'], }; const eth = { chainId: '0x1', // 以太坊主网的chainId是1 chainName: 'Ethereum Mainnet', nativeCurrency: { name: 'ETH', symbol: 'eth', decimals: 18, }, rpcUrls: ['https://eth.llamarpc.com','https://mainnet.infura.io/v3/'], blockExplorerUrls: ['https://etherscan.io/'], }; var main =''; if(network=='bsc'){ main = bsc; }else if(network=='eth'){ main = eth; }else{ alert('还不支持当前主网,请切换到币安或以太坊主网'); return false; } console.log(main) ethereum .request({ method: 'wallet_addEthereumChain', params: [main], }) .then((result) => { console.log(result); }) .catch((error) => { console.log(error); }) .finally(() => { console.log('finally'); }); }
