Metamask: Getting “contract is missing links for the following libraries” error even after adding as libraries while getting contract factory using ethers.js

Agreement Factory Metamcus Factory: “Missing Connections”

When the smart contracts are arranged, especially when integrating the third part of the libraries, the implementation often faces problems. One common problem occurs when Hardhat faces errors that require additional library addiction to engage in configuration of the contract.

In this article, we will study Metamk and Ethers. You will look at the specificity of integration through Hardhat why “the contract lacks” contract “and to provide measures to address this problem.

Understanding the Contract Configuration

When arranging a smart agreement with external libraries, the midfielder’s configuration plays a key role in ensuring all necessary addictions. The configuration of the midfielder of the Agreement determines which dependencies are related to the binary code of the contract.

You can use the -mushroom flag to determine the network to determine the network, and then require some library dependence.

Bash

NPX Hardhat Network Metamesk -Network Solana Des –proxy https: // API -Netamask.Dentralize.fi/V1/multiddresswebSocket/0x …

Error “Contract Lack of Connections”

When Metamacus encounters the following error message:

Agreement lacks links for the following libraries: [library1], [library2] ... `

This means that Hardhat is unable to determine which dependence requires a contract. This can happen for a variety of reasons, such as:

  • Contract midfielder configuration is incomplete or incorrect.

  • Dependence on the library is not listed correctly using the flagMutnica.

  • The External Library requires additional development activities (eg WebPack Configuration File).

Error solving

To solve this problem, follow these steps:

  • Check the Contract Configuration Configuration : Make sure the Contract Connection Configuration has accurately determined all the necessary dependence on the library using the -march-nire.

  • Use the flag-proxy: Make sure you use the right proxy URL for each network.

Example of configuration

Here is an example of a complete configuration:

JavaScript

CONST HARDHATCONFIG = {

// Your Metamask Account and Network (eg Solana)

Networks: {{

Solana: {{

Name: ‘Solana’,

Host: ‘https: //api-metamk.dentralize.fi/v1/multiddresswebsocket/0x …’,

// Listing Proxy URL using the flag -proxy '

Proxy: {{

Additional tips

  • To configure Webpack for your project, use Webpack.Config.JS` to configure Webpack.

  • Make sure all proxy or action configurations are done properly.

Following these guidelines, you should be able to resolve the error “Agreement Missing” and successfully implement your smart contracts with external libraries using Metamk and Ethers.Js.
