ANSWER

Alchemy, Infura, and others, are services offering connection to nodes of the Ethereum network.

Contract deployment means that you broadcast a transaction with specific parameters (data field containing the compiled bytecode, to field empty). But you can only broadcast a transaction to the rest of the network from a node connected to the network.

So apart from using a third-party service, you can also run your own node. For example using the go-ethereum client software.

Then you'll be able to broadcast the transaction through this your own node, instead of a third-party one.

How to disable eslint 'no-undef' for a specific package import?

Asked 2022-Apr-10 at 07:39

I'm working with a framework ('hardhat') that automatically requires a package ('ethers') but eslint keeps calling it out as undefined. Requiring 'ethers' is not a solution because it just breaks everything; but from what I understand, a way to add exceptions to the entire document is to place overrides in a comment block above the entire thing.

Have a look at ESLint globals. Basically, you can declare a global value ethers in your ESLint configuration, and that will be treated as defined in all linted files.

For ESLint >= 7, if your configuration file is .eslintrc, add an entry like:

Does flattening smart contacts reduce deployment costs?

Asked 2022-Apr-02 at 08:54

I want to reduce deployment cost of my ERC-721A contract.

In general; does flattening smart contract help to reduce it's cost?

Currently I am using ethers.js's contractFactory.deploy method with hardhat.

ANSWER

Answered 2022-Apr-02 at 08:54

The compiled contract has the same bytecode whether you flatten it or not.

So no, unfortunately, flattening will not help any cost reduction.

You can use Remix IDE for inspecting bytecode, assembly and deployment cost of your contracts

How to get Uniswap data from Hardhat's mainnet fork?

Asked 2022-Mar-26 at 20:08

I'm using the Uniswap SDK to fetch the price of ETH in the DAI/ETH pool from Uniswap using Hardhat's mainnet fork, except the query is returning the current price of ETH, instead of from the pegged block which is from a few months ago.

How do I fetch Uniswap pool information from Hardhat's mainnet fork? If it's not possible using the Uniswap SDK, is there any workarounds?

Thanks in advance!

Try updating your node version, I was using a node version that is non-compatible with hardhat (Version 10.01) and after update to 16.14.0 that issue was fixed.

How do I interact with Uniswap V2 in a Truffle test suite?

Asked 2022-Mar-12 at 21:28

I am looking for a way to create an automated test suite with Truffle that can test my smart contract's interactions with Uniswap V2. The Uniswap docs briefly mention testing with Truffle but do not provide any examples. I am looking to test it using a mainnet fork with ganache.

I'm guessing it's a similar process to the accepted answer for this question, but I'm specifically looking for a way to do it using Truffle and web3.js.

As an example, if I were testing the following contract:

If you use Uniswap platform to swap a token, you are going to have 2 steps. You are going to approve the token, in this step metamask will pop-up and you are going to confirm it. Then Uniswap will do the actual swap, it takes the tokens out of your wallet and does the exchange for you.

This is the swapExactETHForTokens function
