Metamask: wallet_addEthereumChain在使用多边形mainet时不起作用，而是与孟买多边形一起工作。
Metamask: wallet_addEthereumChain在使用多边形mainet时不起作用，而是与孟买多边形一起工作。
提问于 2021-12-14 09:39:43
我试图以编程方式切换用户的元问询网络。使用wallet_addEthereumChain
当请求对孟买多边形进行网络更改时，它工作得很好，但是在使用Polygon Mainet时不起作用，我得到：Chain ID returned by RPC URL https://polygon-rpc.com does not match 0x137
如果我在元问题上手动添加网络，使用相同的信息就可以了。
- 以上代码适用于多边形孟买。
const { ethereum } = window;
await ethereum.request({
id: 1,
jsonrpc: "2.0",
method: "wallet_addEthereumChain",
params: [
{
chainId: "0x13881",
rpcUrls: ["https://rpc-mumbai.maticvigil.com"],
chainName: "Polygon Testnet Mumbai",
nativeCurrency: {
name: "tMATIC",
symbol: "tMATIC", // 2-6 characters long
decimals: 18,
},
blockExplorerUrls: ["https://mumbai.polygonscan.com/"],
},
],
}); - 这个不工作，并给我:链ID返回的RPC URL https://polygon-rpc.com不匹配0x137‘
const { ethereum } = window;
await ethereum.request({
id: 1,
jsonrpc: "2.0",
method: "wallet_addEthereumChain",
params: [
{
chainId: "0x137",
rpcUrls:[ "https://polygon-rpc.com"],
chainName: "Polygon Mainnet",
nativeCurrency: {
name: "MATIC",
symbol: "MATIC", // 2-6 characters long
decimals: 18,
},
blockExplorerUrls: ["https://polygonscan.com/"],
},
],
});- 下面是用户在我发送请求时所使用的元问题钱包的屏幕截图。

尝试使用web3.utils.toHex()函数将十六进制转换为web3.utils.toHex：
chainId = '137'; chainId = web3.utils.toHex(chainId);
chainData = [{
chainId: chainId,
chainName: 'Matic(Polygon) Mainnet',
nativeCurrency: { name: 'MATIC', symbol: 'MATIC', decimals: 18 },
rpcUrls: ['https://polygon-rpc.com'],
blockExplorerUrls: ['https://www.polygonscan.com'],
}];Ethereum用户
