Missing multicall address for chain id 31337

Hi team!

Thank you for your amazing work. I just faced the issue while trying to develop on a local chain using hardhat.

I keep getting this error on a console every time I try to send some transaction or connect my wallet.

My Metamask points to local hardhat network localhost:8545 and I configured chainId (in Metamask) for this network to be 31337. So it now matches with useDApp hardhat’s chainId. However, this did not help.

May I ask for any help if possible? Thanks!

Guys, i believe you built a great tool, but i must say the documentation isn’t helpful atall. I keep running into issues with this multicall feature, and i cant find a way to fix it in the documentation. The docs doesnt have great step by step directives or even other online resources explaining how to setup even a basic project connected to your local blockchain. I don’t know if the framework is no longer maintained. Its frustrating.

Hi @ironsoul0,

I updated my Config as below and it worked for me

import {
    ChainId,
    Config,
    DAppProvider,
    MULTICALL_ADDRESSES,
} from "@usedapp/core";

const config: Config = {
    readOnlyUrls: {
        31337: "http://localhost:8545",
    },
    multicallAddresses: {
        31337: "YOUR_LOCAL_ADDRESS_HERE", 
        ...MULTICALL_ADDRESSES,
    },
    supportedChains: [
        ChainId.Mainnet,
        ChainId.Goerli,
        ChainId.Kovan,
        ChainId.Rinkeby,
        ChainId.Ropsten,
        ChainId.xDai,
        ChainId.BSC,
        ChainId.Localhost,
        ChainId.Hardhat,
    ],
};

Hope that help you.
