Your branch is ahead of 'origin/pos' by 1 commit.

(use "git push" to publish your local commits)

hint: You have divergent branches and need to specify how to reconcile them. hint: You can do so by running one of the following commands sometime before hint: your next pull: hint: hint: git config pull.rebase false # merge (the default strategy) hint: git config pull.rebase true # rebase hint: git config pull.ff only # fast-forward only hint: hint: You can replace "git config" with "git config --global" to set a default hint: preference for all repositories. You can also pass --rebase, --no-rebase, hint: or --ff-only on the command line to override the configured default per hint: invocation.

Event 인자들중 하나만 체크

await expect(lock.withdraw())
    .to.emit(lock, "Withdrawal")
    .withArgs(lockedAmount, anyValue);

위 코드를 아래와 같이 변경. anyValue가 제대로 동작 안함.

const tx = await lock.withdraw();
const receipt = await tx.wait();
// Find the Withdrawal event in the transaction receipt
const withdrawalEvent = receipt.events.find((e: any) => e.event === "Withdrawal");

// Check if the Withdrawal event was emitted
expect(withdrawalEvent, "Withdrawal event should be emitted").to.not.be.undefined;

// Check only the first argument of the Withdrawal event
expect(withdrawalEvent.args[0]).to.equal(lockedAmount);

anyValue function

import { anyValue } from "@nomicfoundation/hardhat-chai-matchers/withArgs"; wait expect(lock.withdraw()) .to.emit(lock, "Withdrawal") .withArgs(lockedAmount, anyValue); // We accept any value as when arg :error occured like this, AssertionError: Expected 1732243098 to equal function anyValue() { return true; }, but they have different lengths

an issue with fsevents

🏆 해결

Add this to your package.json file, then re-run yarn (or yarn install): "resolutions": { "fsevents": "1.2.9" }
이렇게 하면 node-gyp가 설치됨
그러고나서 위의 resolutions 부분을 제거하고 다시 yarn을 실행해서 fsevents를 최선으로 재설치
안 그러면 "Typeerror: fsevents.watch is not a function" 발생할 수 있음.

create2 함수

아래 함수는 UniswapV2Factory에서 사용되는 코드임

bytes memory bytecode = type(UniswapV2Pair).creationCode;
bytes32 salt = keccak256(abi.encodePacked(token0, token1));
assembly {
    pair := create2(0, add(bytecode, 32), mload(bytecode), salt)
}

Unlike create, which generates the contract address based on the address of the creator and how many contracts it has created (nonce), create2 generates the address using the creator's address, a provided salt, and the hash of the initialization code. This allows for predictable computation of the contract's address before the contract is actually deployed.

Endowment (0): This is the amount of Ether, in wei, that is sent to the new contract upon creation. In this case, it's set to 0, meaning no Ether is sent.
Memory Start (add(bytecode, 32)): bytecode is the initialization code for the contract you want to create. In Solidity, contract bytecode is often stored in an array, and this array includes a 32-byte length prefix. add(bytecode, 32) calculates the starting point of the actual bytecode, skipping the first 32 bytes which represent the length of the bytecode. This is necessary because create2 requires a pointer to the start of the actual code, not the length prefix. Size of Code (mload(bytecode)):
mload(bytecode) is used to load the first 32 bytes of bytecode, which, as mentioned, contain its size. This tells create2 how much of the memory starting from add(bytecode, 32) it should read and use as the initialization code. Salt (salt):
The salt is a 32-byte value that you provide. It's part of the formula used to calculate the address of the new contract. In your code, salt is generated from the hash of two token addresses, which helps ensure that each pair of tokens gets a unique contract address.

eth.getTransactionCount("0x8B595d325485a0Ca9d41908cAbF265E23C172847")
여기서 나타나는 Nonce를 트랙잭션에서 사용하는 것임.
다른 방법
- const nonce = await provider.getTransactionCount(admin.address);

wait 함수의 인자

The wait() function of ContractTransaction takes a single optional argument, which is the timeout in blocks. The default timeout is 10 blocks. This means that the wait() function will block for up to 10 blocks before throwing an error if the transaction has not been confirmed. You can increase the timeout period by passing a higher number to the wait() function. For example, the following code will block for up to 20 blocks before throwing an error:

2.Add your user to the docker group.
$ sudo usermod -aG docker $USER
3.Run the following command or Logout and login again and run (that doesn't work you may need to reboot your machine first)
$ newgrp docker

run_node 스크립트에 bootnode 항목에 들어가는 enode의 IP값이 맞아야 함.
static_node.json에 enode 정보를 정확히 써줘야 함.
Node1에 외부 IP를 할당했을때 재부팅 필요함.

Imported Accounts are accounts you import using a private key string or a private key JSON file, and were not created with the same Secret Recovery Phrase as your wallet and accounts. For this reason, these accounts will not appear automatically when you restore your MetaMask account with your Secret Recovery Phrase. The data associated with your MetaMask Secret Recovery Phrase cannot be added or extended to the imported account.

static call

staticcall works in a similar way as a normal call (without any value (sending eth) as this would change state). But when staticcall is used, the EVM has a STATIC flag set to true. Then, if any state modification is attempted, an exception is thrown. Once the staticcall returns, the flag is turned off.

/// @notice This plugin allows some designated EOA or smart contract to temporarily

/// This base session key plugin acts as a 'parent plugin' for all specific session

/// It allows for session key owners to access MSCA both through user operation and

PR에 설명 달기

## Motivation
We would like to accumulate the money for Poohnet Fund which will be used to support the real world projects which have content to make our world friendly.

## Solution
commit 789c3cf6c : Change the code for generating inflation for Poohnet Fund
commit c595c22a9 : Apply configuration for make the inflation start

supportsInterface

function supportsInterface(bytes4 interfaceId) public view override returns (bool) {
    return interfaceId == type(ISessionKeyPlugin).interfaceId || super.supportsInterface(interfaceId);
}

storage modifier

EnumerableSet.Bytes32Set storage sessionKeySet = _sessionKeySet[msg.sender]; Purpose: This line declares a variable sessionKeySet that refers to a set of session keys for the message sender (msg.sender). The storage modifier indicates that sessionKeySet is a pointer to the data located in the contract's persistent storage, not a temporary copy. This is crucial in Solidity because changes to a storage variable directly modify the state on the blockchain.

unchecked block

The unchecked block is used here to tell the compiler not to check for overflows when incrementing the index i. This can save gas since the overflow is unlikely given the controlled environment of the loop (i.e., looping over an array length

CREATE a CONTRACT with 2 SAME addresses on 2 DIFFERENT chains

address = bytes20(keccak256(0xFF, senderAddress, salt, bytecode))

How to deploy my contract on 2 different chains with the same address? Now, let’s answer to the question: How to deploy a smart contract with the same addresses in 2 different chains?

You can do it with the CREATE2 opcode by providing the same salt on different chains. (easier than providing the nonce because you can’t fully control it)

TypeError: Cannot read properties of undefined (reading 'provider'):

이런 에러가 떨어지는 이유가 아래 import 문 때문인데, 
import { ethers } from “hardhat”
hardhat의 ethers 버전은 내가 쓰려는 버전보다 낮아서 그런 것이다. 아래와 같이 바꾸면 됨. 
import { ethers } from "ethers";
hardhat의 ethers 버전과 나의 ethers 버전이 다르면 또 문제가 생김.

const provider = ethers.provider;
signer = await ethers.getSigner();
위에서 발생하는 “TypeError: Cannot read properties of undefined (reading 'provider')” 문제는 모두  아래와 연관이 있는 것이고,
ethers: typeof ethers & HardhatEthersHelpers;
이것은 hardhat.config.ts에 import "@nomicfoundation/hardhat-toolbox"; 추가해야 함.
결국 provider와 getSigner는 hardhat.config.ts와 관련된 것이었음.

hardhat의 ethers를 쓸때 이런일이 발생함으로 6.7.0을 써야함. 그렇다면 hardhat은 내 ethers를 쓴다는 얘기? 내꺼 쓰는게 맞음. 그러면 뭐하러 import { ethers } from "hardhat"; 이걸쓰냐구??? 어쨌든 hardhat의 node_modules에는 hardhat 깔리게 없음.
