`openzeppelin` 같은 외부 프로젝트 적용

flux-finance 프로젝트 처럼 openzeppelin 같은 외부 프로젝트를 코드에 직접 포함시키는 것도 방법
- contracts/external/openzeppelin, 여기는 src 대신 contracts 폴더를 사용.

Random Key 생성 (#키생성 #키 생성 #Key Generation)

yarn keys

Python 참고 코드

여기서 0x를 쓰면 안됨.

hex_string = "48656c6c6f20576f726c64" # Hex encoded string for "Hello World" byte_string = bytes.fromhex(hex_string) regular_string = byte_string.decode("utf-8")

from datetime import datetime datetime.fromtimestamp(7214123987)

print(f"{a:08x}{b:016x}{c:08x}") 0000006400000000000227b200000005

Python에서 Ethereum 호출

w3 = Web3(Web3.HTTPProvider('https://eth-sepolia.g.alchemy.com/v2/73I-qvN9yqtRcajnfvEarwA2FNHM4Nph')

ethers v5

(ethersv5) "ethers-v5": "npm:ethers@5",

Private key로 keystore 파일 만들기

(keystore, decrypt, encrypt)

account import

Create mykeyfile and set private key in the file (0x는 붙이면 안됨)
geth --datadir ./mykeystore account import mykeyfile
mykeystore 폴더에 파일 생성됨

decrypt

const data = JSON.parse(
  fs.readFileSync(path.resolve(Utils.getInitCWD(), this.key), "utf-8")
);
const account = hre.web3.eth.accounts.decrypt(data, "pooh2024");
this.key = account.privateKey;

Deploy factory contract (Deterministic deployment proxy)

Reference

pooh-geth/poohnet/deploy-deployer.sh on pooh-geth
npx hardhat test test/all-basic.ts --grep CREATE2 on web
npx hardhat run scripts/deploy-with-create2.ts --network localnet on web

Check if the factory exists

The Create2 factory contract will be deployed at the address 0x4e59b44847b379578588920cA78FbF26c0B4956C. You can check if this contract has already been deployed to your L1 network with a block explorer or by running the following command:

cast codesize 0x4e59b44847b379578588920cA78FbF26c0B4956C --rpc-url $L1_RPC_URL

If the command returns 0 then the contract has not been deployed yet. If the command returns 69 then the contract has been deployed and you can safely skip this section.

Fund the factory deployer

You will need to send some ETH to the address that will be used to deploy the factory contract, 0x3fAB184622Dc19b6109349B94811493BF2a45362. This address can only be used to deploy the factory contract and will not be used for anything else. Send at least 1 ETH to this address on your L1 chain.

Deploy the factory

Using cast, deploy the factory contract to your L1 chain:

cast publish --rpc-url $L1_RPC_URL 0xf8a58085174876e800830186a08080b853604580600e600039806000f350fe7fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffe03601600081602082378035828234f58015156039578182fd5b8082525050506014600cf31ba02222222222222222222222222222222222222222222222222222222222222222a02222222222222222222222222222222222222222222222222222222222222222

Wait for the transaction to be mined

Make sure that the transaction is included in a block on your L1 chain before continuing.

Verify that the factory was deployed

Run the code size check again to make sure that the factory was properly deployed:

cast codesize 0x4e59b44847b379578588920cA78FbF26c0B4956C --rpc-url $L1_RPC_URL

막오른 '세상 만물 투자' 토큰증권…내년 본격 궤도 오르나

입력 2024.12.25.
토큰증권은 종전에 돈을 넣기 어려웠던 자산을 잘게 쪼개 금투상품으로 전환하는데 요긴하다.
이 때문에 이번 22대 국회에 발의된 법안(자본시장법·전자증권법 개정안)은 비정형 증권의 발행 및 유통을 법제화해 불확실성의 족쇄를 없애는 데 초점을 맞췄다.
업계에서는 맨 먼저 보편화할 토큰증권으로 부동산 조각투자 상품을 꼽는 이들이 많다.
미술품과 저작권 등 자산은 가치 평가가 까다롭지만 부동산은 가치 산정과 거래 시기 예측이 비교적 쉽고, 실제 건물·토지를 토대로 하는 만큼 배당 안정성과 환금성 면에서 더 유리하기 때문이다.

ethers v5 vs ethers v6 issue

all-basic.ts를 두개로 분리함

all-basic.ts

yarn test:basic 로 테스트

특이하게, ethers.provider.send('eth_sendRawTransaction', ...) 함수를 ethers v6 환경에서 사용하려고 하면 아래의 에러가 뜸

InvalidArgumentsError: Trying to send a raw transaction with an invalid chainId. The expected chainId is 31337
  at EdrProviderWrapper.request (/Users/jay/work/web/ex/node_modules/hardhat/src/internal/hardhat-network/provider/provider.ts:453:19)

all-balic-ethers5.ts

yarn test:basic5 로 테스트
ethers.provider.send('eth_sendRawTransaction', ...)
ethers.provider.send('eth_call', ...)
이런 복잡한 처리를 할 때는 어쩔수 없이 ethers v5를 이용한 소스를 써야 할 듯함.
- 이미 참고 소스가 존재하고, 테스트 코드에 복잡성을 따로 파일로 분리시킨다면 문제 없을 것으로 보임.

Issues

pooh-geth `cancun` 미적용 문제

contract-dencun과 contract-seaport 컨트랙트를 사용할 때, localnet에서는 테스트가 안됨.
원래는 contracts 폴더 안에 있으나, localnet과 연동시에는 바깥으로 옮겨야하는 불편함이 있음.
localnet으로 쓰는 pooh-geth가 Cancun evm으로 빌드되어 있지 않기 때문임.

다음의 코드 참고 (hardhat.config.ts)

{
  version: "0.8.24",
  settings: {
    evmVersion: process.env.EVM_VERSION || "cancun",
    ...
  }

}

환경변수 값에 따라서 컴파일 대상을 변경할 수는 없는 것으로 보임.
- 참고로, 테스트되는 파일의 위치나 이름으로 환경변수 값을 바꿀 수는 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.

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:

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.

/// @title Base Session Key Plugin
/// @author Decipher ERC-6900 Team
/// @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

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)

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.

"period": This refers to the block time, the time interval between consecutive blocks. In this case, 1 means one second. This is a very fast block time, suitable for private or test networks where quick consensus is desired. In public networks, such short intervals could lead to network instability due to propagation delays and increased likelihood of forks.
"epoch": The epoch length, set here as 30000, is significant in Clique PoA. An epoch is a period after which the list of authorized signers can be updated. In Clique, every epoch blocks, a special block called the epoch transition block is generated, which contains the list of authorized signers for the next epoch. The number 30000 means that every 30,000 blocks, the network has an opportunity to update the list of signers.

Hardhat / Foundry

Integrating with Foundry

If you have an existing Hardhat project and you want to use Foundry in it, you should follow these steps.

First, run forge --version to make sure that you have Foundry installed. If you don't, go here to get it.

After that, install the @nomicfoundation/hardhat-foundry plugin:

npm install --save-dev @nomicfoundation/hardhat-foundry

and import it in your Hardhat config:

import "@nomicfoundation/hardhat-foundry";

To complete the setup, run npx hardhat init-foundry. This task will create a foundry.toml file with the right configuration and install forge-std.

submodule이 아래와 같이 추가됨

[submodule "ex2/lib/forge-std"]
  path = ex2/lib/forge-std
  url = https://github.com/foundry-rs/forge-std

Node workspaces

😈 Structure and Configuration

Workspace Root: A single workspace has a root directory, usually with a package.json file that includes a workspaces field.
Sub-packages: Inside the root, there are subdirectories for each workspace, each with its own package.json file.
Shared Configuration: Dependencies and scripts can be shared across workspaces, which is especially useful for common configurations and shared libraries.

push 하려고 할때 아래와 같은 문제 발생 --> github remote의 브랜치가 더 최신버전일때 발생
이것을 가장 최신의 확실한 방법임. 그냥 rebase 해주면 됨

git rebase origin master

이것 에전 설명인데, 일단 그냥 참고용으로 그냥둠

$ account-abstraction git:(test-flow) ✗ git push -f
To github.com:linked0/account-abstraction
 ! [rejected]        test-flow -> test-flow (non-fast-forward)
error: failed to push some refs to 'github.com:linked0/account-abstraction'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

이럴 경우는 다음의 단계를 거침
- git fetch origin
- git reset --hard HEAD~1
- git rebase origin/pooh-version
- git reflog : 추가로 푸시하려고 했던 커밋을 찾아내기
- git cherry-pick <커밋아이디> : 추가하려고 했던 커밋 아이디를 체리픽
상세 설명
- 현재 리모트 기준으로 HEAD + 1 까지 진행된 상태에서, 로컬의 HEAD와 리모트의 HEAD가 불일치된 상태
- 그런데, 그 불일치 상태에서 추가적인 commit이 진행된 상태에서 push를 하려고 해서 문제 발생
- 따라서, HEAD~1까지 되돌린후에 리모트의 HEAD를 적용한 후에,
- 현재의 commit을 적용해야하는 것임

로컬의 커밋을 날려먹었을때

git reflog를 사용하면 커밋 아이디를 확인할수 있음 git cherry-pick를 이용하여 가져오면 됨.

$ git reflog
8fd79d7 (HEAD -> pooh-version, origin/pooh-version) HEAD@{0}: cherry-pick: fixup;
bc5852b HEAD@{1}: rebase (finish): returning to refs/heads/pooh-version

MacVim을 Spotlight에서 보도록 하기

For those with Yosemite and MacVim from homebrew not showing up in Spotlight, using an alias works.

(Be sure to delete any MacVim that is already in /Applications.)

From the Terminal:

Uninstall existing: brew uninstall macvim Install latest: brew install macvim Open directory in Finder. Ex: open /usr/local/Cellar/macvim/7.3-64 In Finder, right-click on the MacVim.app icon and select "Make Alias". Copy the alias you just created to the /Applications folder. Spotlight will index the MacVim alias.

Source: https://github.com/Homebrew/homebrew/issues/8970#issuecomment-4262695

Mac Spotlight에서 특정 애플리케이션 찾지 못할 때

First, turn off Spotlight: sudo mdutil -a -i off

Next, unload the metadata file that controls Spotlight's index: sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist 여기서 에러날 수 있음 그냥 무시하고 다음으로 넘어감.

The following command re-loads the index: sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

Finally, turn Spotlight back on: sudo mdutil -a -i on

Mac에서 Sublime Text를 커맨트창에서 실행시키기

💎 ChatGPT - Buddy Guidance for you, Codex: Show me the original sentence, a grammatically and semantically correct version (as few corrections as possible), a Korean translation. And also show me your recommened version and the concise, natural, not to formal version suitible for team meeting. Each version is written with a simple prefix in one line. And then if there are any idioms or different words, explain them very briefly after the translation. If the original sentences are written in Korean, you should start with the sentences translated into English as original ones. And evaluate the my english proficiency level from 1 to 10, 10 being native speaker level anc check the problems in my english brefely.

And then, thoroughly respond to the content of my message and briefly explain any relevant background, technology, current state, or future outlook.

if I write ":ca", check my sentences for grammar unconditionally before answring.
