在 private mempool 的大背景下, 用户的交易细节都属于隐私, 是极其有限的, 例子中介绍了如何仅通过 univ2 的 pool 就完成套利. 核心就是如下函数, 原推中没有截全, 我直接补全了
github.com/flashbots/simp…
github.com/flashbots/simp…
截图中的函数接受2个池子的地址作为参数, 套利合约通过对比两个池子中当前资产的价差来判断套利空间进而执行交易完成套利, 得益于 matchmaker 只发送能完成交易的bundle 的特性, 所以如果套利失败也不用担心gas损失, 因为套利失败那么这比套利交易根本不会上链.

1️⃣ SEC Identifies Algorand and Five Other Tokens as Securities amidst Bittrex Case
The #SEC claims that listing of tokens OMG, Dash, ALGO, Monolith (TKN), Naga (NGC) and IHT Real Estate Protocol (IHT) on #Bittrex constituted unregistered securities offerings.
The #SEC claims that listing of tokens OMG, Dash, ALGO, Monolith (TKN), Naga (NGC) and IHT Real Estate Protocol (IHT) on #Bittrex constituted unregistered securities offerings.
Quite interesting considering that previously, Gensler had promoted/commended the #Algorand token, one of the six under fire.
This promotion falls under the Securities Act of 1933 and the Securities Exchange Act of 1934, which regulates the offer and sale of securities

Flashbots RPC
这是一款面向以太坊普通用户的免费产品，你只需要在加密的钱包中将 RPC（网络节点）设置为Flashbots RPC，就可以将交易发送到Flashbots的私有mempool，从而免受抢先交易/三明治攻击的侵害。
Metamask 钱包连接 Flashbots RPC 方法如图:

2/ In the blockchain transaction ordering process, the block producers are responsible to aggregate, selecting, and reordering transactions in the #blockchain network based on the given economic incentives thus creating opportunities for #MEV
3/ #MEV refers to the maximum value that can be extracted from a block more than the standard block reward and gas fees by including, excluding, and changing the order of transactions in a block
Continue to our topic about Maximal Extractable Value (MEV), we would discuss deeper in #flashbots in this thread.

MEV is a dynamic that allows miners to maximize their profit by determining the order of transactions on a blockchain network to their advantage. This includes arbitrarily reordering, including, or excluding transactions within a block at the expense of users.

After the Merge, rewards to miner will decrease, resulting in MEV will increase the percentage of profit for miner. Therefore, the MEV problem is getting important. Several solutions arose to mitigate these negative externalities. Most prominently, #Flashbots.

Secret Shared Validators (SSV), or Distributed Validator Technology (DVT), is the first protocol that encrypts a validator key and splits it into KeyShares. These KeyShares are distributed to non-trusting nodes run by operators, fault-tolerant for Ethereum staking.

We know that ETH 2.0 is going to change the consensus form PoW to PoS to verify transaction via staking. In order to be more decentralized, we need more nodes to participate. But if there is a node faces some security or off-line risk, the node will be penalized.

Most of the articles and information available on #Flashbots are aimed at developers and technical people. Technical knowledge is needed to realise the full potential of Flashbots. On the other hand, it also limits the possible tool adoption among users for its other benefits.
pro tip: 如何正确使用 Flashbots?
1/ 通过 Flashbots 发送交易时，只有交易成功时才支付矿工费，更节约交易成本。
可以减少在 Uniswap Dex 上兑换被夹的可能（当前版本 v0.4，交易未隐私，仍可以被 relayer 和矿工看到）；避免在 Opensea 扫地板时被别人抢先扫掉，交易 reverted 仍然需要支付 gas。

2/ 在 metamask 中配置 Flashbots RPC
选择 Custom RPC 添加网络，正确填写以下信息（仅适用于以太坊主网）。
网络名称: Flashbots RPC
新增 RPC URL: rpc.flashbots.net
链 ID: 1
Currency Symbol: ETH
docs.flashbots.net/flashbots-prot…

3/ 检查 metamask 是否正确选择 Flashbots RPC 网络
通过 Flashbots RPC 网络发送交易，长时间未被打包会被丢弃；这时需要注意的是，如果有进行中的交易，不能切换网络至以太坊主网，否则会将交易发送给以太坊主网的 RPC 节点，导致失败交易被打包，从而浪费 gas。

1/ @Uniswap v3 introduces a new form of MEV attack — Just-in-Time Liquidity (JIT), that allows LPs to add and remove concentrated liquidity positions atomically in one block. Sophisticated actors are running JIT bots to sandwich trades, to the detriment of pre-existing LPs 👇🧵
2/ Using @DuneAnalytics, we find the @Uniswap positions that are added and removed in the same block for the same LP. From this, we calculate the revenue from the fees of the sandwiched trade, and subtract the gas costs required to perform the JIT attack:dune.xyz/embeds/233623/…
3/ Only 2 MEV #flashbots are presently capable of JIT attacks. Over >$1M USD in profits have been gathered by JIT bots, to the detriment of frontrun non-sophisticated @uniswap v3 LPs. @bertcmiller @phildaian dune.xyz/embeds/233623/…

Why mint via a bot instead of through a UI? Most NFT drops have a limited number of items avail to mint. It's your job to get one (or many) of those scarce jpegs. To do this, you need your transaction(s) to be prioritized in the mempool and picked up before the drop sells out.
MEV (Miner Extractable Value) seems like such a complex attack that traders ignore it. But there's too much at stake though. Let me ELI5:

1. What is MEV? It's the additional profit a miner can get by re-ordering, including or excluding transactions from the blocks they are in charge of producing.
While winning a block is fair, the winning producer gets to play God for 1 block... and reap excess profits

2. Is it a big deal? They've made $235 million in the past month. For example, when you set a 0.5% slippage tolerance on @Uniswap, bots are likely creaming off the top
The topic of the moment: We've compiled a public wiki on #MEV to talk about the differing approaches projects (including us) are taking as they venture into the proverbial dark forest @danrobinson @samczsun @paradigm.

Over $370m has been extracted by miners since 2020. Attacks have only become more sophisticated with time - besides the famed #front-running incidents, back-running attacks, time-bandit attacks and liquidations are all par for the course.

That’s not to say one can’t play bots at their game. Salmonella intentionally exploits the generalised nature of front-running setups, while over at @kattanatrade a front-runner paid 68 ETH to the miner and ended up with tokens he couldn't sell.
