Flashbots

Flashbots is a research and development organization working on mitigating the negative externalities of Maximal Extractable Value (MEV) and avoiding the existential risks MEV could cause to stateful blockchains like Ethereum. Our primary focus is to enable a permissionless, transparent, and sustainable ecosystem for MEV, via a three-pronged approach:

  • Illuminate: Bringing transparency to MEV activity.
  • Democratize: Democratizing access to MEV revenue.
  • Distribute: Enabling sustainable distribution of MEV revenue.

Our efforts are separated into three sub-organizations:

  • Product: builds core infrastructure and ecosystem tooling that redefines the block production supply chain. This includes MEV-Boost, SUAVE as well as Flashbots Protect RPC, mev-geth, MEV-Inspect and MEV-Explore.
  • Research: an open, transparent, and collaborative research effort that explores MEV market dynamics and blockchain design challenges at the intersection of economics, security, and cryptography. To fuel the collaborative nature of our research, anybody can submit a Flashbots Research Proposal (FRPs) and might become eligible for a grant.
  • Coordination: an organizational effort to streamline operational processes, interface with external teams in the ecosystem and scale ourselves to maximize our impact.

Flashbots Research and Product are tightly-coupled dual engines that propel our organization forward in a phased approach:

  • Long-term oriented research efforts spec out and update our roadmap, define our organization’s phases and identify key milestones.
  • Milestone-oriented engineering efforts ship core infrastructure and ecosystem tools while collecting data and other artifacts that feed back into research.

Our work is open source and you can follow our progress in each respective repository of the Flashbots organization. Anyone is welcome to comment on an issue or pick it up entirely.

Community

The best way to interact with the Flashbots community is through our forum, which is our central communication platform for conversations, announcements and information sharing. We also publish monthly transparency reports that aggregates information and provides summaries on everything Flashbots and MEV.

Join us!

We are not your typical project, we are fully remote and our principles are based on that of a pirate hacker collective. If you are a self-directed individual who puts collective success above your own and is motivated by solving challenging problems with asymmetric impact, you will fit right in.

pm's Issues

Regarding Proof of Stake

With adoption of Proof of stake, flashbots will soon become obsolte and therefore stop to work. Not?

Why ban from Discord?

I got banned from the server,
I was asking for help in identifyng if the smart contract that was shared on twitter was Legit or not!

This is quinn.kin, btw
Pls unban me.

transactions was included as a normal transaction.

It looks like there're some chances that a transaction could be included as a normal transaction sometimes. I guess it might be caused that the transaction was firstly included in a block but the block became uncle block after a reorg. Transactions in the uncle block was put into the pending tx pool and was included later as a normal block.

Any idea to solve this problem?

Ilogical error when calling getConflictingBundle - Error: Target bundle errors at top of block

I am trying to use getConflictingBundle endpoint and always get this error when my txs are 100% sure not reverting, doesn't make any sense .

  1. when same tx sent to mainnet without any relevant state changes there are no reverts
  2. when simed in tenderly no reverts
  3. when siming with flashbots all good.

With getConflictingBundle however, this error happening almost everytime , even for bundles which were included!

What's this all about ? There is nothing on the documentation providing insights into this but seems like some issue with the way flashbots is simulating the transaction ?

Roast Master (20min):
- Q1: How do you expect a switch to PoS would change the MEV landscape? PoS has predictable block times, proposers can see when they will be able to create blocks, and a proposer can try to create a block multiple times before they propose it. How would MEV extraction have to adapt?
- Q2: How would MEV extraction look like in a world with sharding or rollups, where instead of all transactions passing through a single proposer you have different proposers active in different "domains" at the same time?

  • Roast Questions:
    1. How much burden of minimizing MEV should be placed at the network level vs the contract/application level?
    2. In the near-to-mid term, should all high-volume front-end applications start routing directly to mining pools the way 1inch is doing?
    3. What would be the impact of infrastructure of traditional financial markets starting to make its way into crypto, such as Payment for Order Flow to wallets or interfaces? (h/t Trent Elmore)
    4. What is the likelihood of advances in cryptographic techniques enabling a meaningful reduction in MEV, vs addressing MEV primarily through game theory and economic mechanism design?
    5. Does the practice of node and mining pool operators actively sorting/filtering transactions based on their outcomes make it harder to fight back against the STABLE ACT or other future legislation that looks to hold nodes and validators accountable for certain types of transactions? (h/t Alex Lindgren)

miners for fastMode

Is there any list of miners for fastMode , can get such info from doc or discord .

The reason is after testing fastMode more than 30 days with 50+ tx , it look like only [Ethermine] mined my fastMode tx.

Thanks.

    Q3. Should protocols and their users have rights to protocol-specific MEV / should a portion of MEV go back to users or the DAO? If so, how might such a mechanism work?
    Q4. In some ways, MEV resembles something like climate change: a looming existential collective action problem, but with negative effects that are too difficult to feel on an individual or local level. What’s the most important thing we need to do to get people to care?

Unable to decode bundle

Hey,

When simulating a bundle, everything works just fine, however, when submitting it using:

    const bundleReceipt = await flashbotsProvider.sendRawBundle(
      signedBundle,
      targetBlockNumber
    );

Then I get the following error message:

{ error: { message: 'unable to decode bundle', code: -32000 } }

I instantiate my flashbotsProvider as follows:

    const flashbotsProvider = await FlashbotsBundleProvider.create(
      await alchemy.config.getProvider(),
      new Wallet(process.env.SIGNER_PRIVATE_KEY, alchemy)
    );

Any thoughts?

Proposal: formalize a 'Flashbots' Service Provider and User Guidelines

Formalizing a Flashbots Service Provider and User Guidelines Rulebook

@notice Disclaimer: this is not legal advice, I am not a lawyer / attorney / barrister. **
@note 'Application' refers to the flashbots network and relay

An early draft as discussed in #65, formalizing policies and relationships are important both on-chain and off. However the principles outlined here do not cover the commodification of the flashbots service, that is to say it focuses more on facilitating fair market structure than implementing effective guidelines that clearly prohibit certain actions as stated in the proposal itself:

Originally posted by thegostep April 14, 2021
(...)
Fair Market Principles for MEV is required in the Flashbots Alpha due to the technical limitations in the early stage of the project which are mitigated on the basis of trust. Flashbots aims to eliminate these trust requirements in future releases of the system.

Block producers connected to the Flashbots Alpha are expected to act in the best interest of the Flashbots network, the Ethereum network, and its various stakeholders. Namely, the Flashbots network aims to uphold the properties of fairness, efficiency, transparency, and permissionlessness. Block producers participating in the Flashbots Alpha are expected to collaborate in the development of an ecosystem for MEV extraction which reinforces the security and stability of the Ethereum network.

In the event of a breach of these principles by one of the block producers, the Flashbots core devs may act on behalf of stakeholders in disabling the access to the Flashbots network until the breach is rectified. The Flashbots core devs aim to provide technical support to block producers on a best effort basis to help resolve any technical issues.

Find the full proposal here: https://hackmd.io/@flashbots/fair-market-principles

A Preliminary outline

The following clauses and sections are subjects of interest to the entire community (both flashbots and the greater ethereum ecosystem in general). This is a first pass at outlining a policy framework that is modeled after existing practices (e.g. SLA agreements for B2B).

Principles and Statements

Conduct restrictions

forbidden actions includes examples of conducts that in principle are always against the law and may result in a prejudice to (flashbot's) interests.

User protection statements

By “user protection” we mean provisions to explicitly forbid activities that may be detrimental to other users of the service. All these options are already per se illegal, but stating them explicitly doesn’t hurt.

Scraping restrictions

Scraping is an automated process by which a software is able to scan and extract targeted information from websites. Although the distinction is not clear cut and most importantly not legally defined, while search engines – such as Google – crawl the web indistinctly to index pages and show them as search results, Scraping is usually targeted at a specific content or at one or more specific websites.

However, scraping is not per se illegal. Therefore, an accommodation should be made in which there is a user registration system whereby people looking to scrape data can be serviced in a separate subsystem/infrastructure so as to not compromise the health and liveness of the primary application.

Suggested addition for users in Australia (also beyond): no relationship of employment, agency or partnership created between the involved parties (this relates to searchers doing sponsored transactions)

Disclaimers of warranties, limitations of liability and indemnity

Specific liability limitations

(list with specific statements for liability limitation, going deep with examples and statements)

Any losses that are not the direct consequence of a breach of the Terms by the Owner.

Any loss of business opportunities and any other loss, even indirect, that may be incurred by the user (such as, but not limited to, trading losses, loss of revenue, income, profits or anticipated savings, loss of contracts or business relationships, loss of reputation or goodwill, etc.).

Damages or losses resulting from interruptions or malfunctions of the Application due to acts of force majeure, or unforeseen and unforeseeable events and, in any case, independent of the will and beyond the control of the Owner, such as, but not limited to, failures or disruptions of telephone or electrical lines, the Internet and / or other means of transmission, unavailability of websites, strikes, natural disasters, viruses and cyber attacks, interruptions in the delivery of products, third-party services or applications.

  • Statement that places some responsibility on users to implement sufficient security and malware practices

  • Limitation of liability to compensation for B2B cases

Acceptable use

Conduct restrictions

This first group of forbidden actions includes conducts that in principle are always against the law and may result in a prejudice to (flashbots) interests.

  • Excessive use

  • Excessive use of the service

  • Excessive use of the API

“Acceptable use” statement (also sometimes called forbidden use if framed negatively). This should define what users may do on or with "your application", in order to be able to take actions against them if they violate the rules.

By “user protection” we mean provisions to explicitly forbid activities that may be detrimental to other users of the service. All these options are already per se illegal, but stating them explicitly doesn’t hurt.

End of Draft

Thank you for taking the time to read this,

Sam

MEV Roast 12 Agenda: MEV from A to Z

Date: Thursday, Feb 25
Time: 11:30am EST / 8:30am PST / 4:30pm UTC / 12:30am China Standard Time

Tl;dr: How large is MEV? Why does MEV matter as a security metric to protocol designers and users? What is the animal mascot for MEV and why is a platypus the correct answer? Follow the release of MEV-explore v0 (explore.flashbots.net) this week, join us on an exploratory tour of MEV with Flashbots & Roast Master Hudson Jameson into the methods and preliminary results of quantifying MEV: from the currently Extracted MEV to the Total Extractable MEV in any given block.

MEV Roast is a monthly tradition from the MEV Pi-rate Ship, a neutral, chain-agnostic, interdisciplinary research collective that supports MEV-related theoretical and empirical research.

Conference Link | Flashbots Calendar | Slides

Part 0: Introduction & Memes (10min)

  • MEV Russian Doll: a Strawman decomposition
  • Flashbots & MEV

Part 1. MEV: from A to Z (50min)
Each Roast we will invite MEV Ship research collective members to present insights from MEV-related research they are working on or interesting early stage proposals for community feedback.

  • Extracted Value: quantifying on-chain MEV activities on Ethereum
    • Navigator: Alex Obadia (Slides) (10min)

    • Navigator: Phil Daian (Slides) (15min)
    • Roast Q&A (15min)

Part 2. Roast Questions (30min)
Q1: Can a contract or program be developed that detects different types of MEV and instructs a contract to reverse transactions that front run, censor, or re-order transactions?
Q2: Does MEV include information that hasn’t hit the chain yet, such as a transaction from a separate chain, like Cosmos or Avalanche, that is clearly on it’s way to Ethereum, is there new ways for miners to look at other chain's bridge transactions to get rewarded? Can patterns develop outside of the enclosed main protocol that can influence protocol level actions?
Q3: If a miner is looking at an oracle feed and knows or can delay the oracle data result, is that MEV? Example: Betting on the sports game and a miner can bet on a game’s outcome before the oracle settles the game if they know what the oracle is about to say?
Q4: Have mining pools openly admitted to doing MEV tactics to increase their profits and if so, what position do they take with regards to MEV?
Q5: What is the animal mascot for MEV and why is a platypus the correct answer?

MEV GETH on Binance Smart Chain

Hi, may I know do you have the MEV GETH on Binance Smart Chain?
As I am running a full node on BSC now, and I hope Flashbots to support Binance Smart Chain because I found many front running MEV happening on Binance Smart Chain too.

Using flashbots as a backdoor path to account abstraction

One of the long-running desires of many in the Ethereum protocol community is to add some form of account abstraction. Account abstraction (see also: this video where I talk about the concept) is the idea that instead of every transaction needing to start from an "externally-owned account" (EOA) controlled by a private key, transactions could start directly from contracts (and EOAs could eventually even be deprecated entirely).

There are many use cases for this: smart contract wallets (eg. see here where I make the case for social recovery wallets), privacy-preserving tools like Tornado Cash, etc. Today, smart contract wallets are difficult to use because a transaction must start from an EOA, and the EOA must pay the gas fees, so someone using a smart contract wallet must have some of their ETH in an EOA to pay for gas, adding significant complexity (and wasted gas). Centralized relayers can mitigate this to some extent, but some inefficiency ultimately still remains.

Flashbots can solve this! Flashbots is basically a very powerful and more efficient generalized and decentralized relayer protocol, and it should be possible to build a plugin to turn it into a relayer for smart contract wallets:

  • When a user wants to make an action with a smart contract wallet, they generate the ABI encoding of the function call to their wallet. This ABI encoding contains:
    • The target, calldata and gaslimit (or an array of each, if they want to make multiple calls)
    • A fee, a quantity of ETH that the wallet sends to the block.coinbase (post-EIP-1559 this could be extended to max_total_fee and miner_bribe)
    • The signature (or multiple signatures), which the contract wallet verifies
  • The user publishes a package containing this ABI encoding and their smart contract wallet address to a specialized p2p subnet, which only rebroadcasts encodings if they follow some rules that guarantee that they actually will pay a sufficient fee if included.
  • Specialized flashbots relayers that "speak" this sub-protocol would live on this network and package proposals consisting of these packages. To save gas, they could simply make a single wrapper transaction that includes all of the calls.

There is a lot of room for creativity in what those verification rules could be. One simple option is to check for four conditions:

  1. The fee is sufficiently high
  2. The contract wallet fits a template that shows that it can accept the encoding
  3. The contract has enough funds to pay the fee
  4. If you execute the contract, the execution gets past the signature verification stage

Another option is more limited but simpler: if the total gaslimit is low enough (eg. under 400000?), the system could simply check that the block.coinbase's balance increases by a sufficient amount during transaction execution. This could allow the privacy-preserving use cases as well as smart contract wallet creation.

This could give us most of the benefits of account abstraction without needing to make deep changes to the Ethereum protocol itself (eg. EIP 2938), and so it seems worth making a serious effort to explore and implement.

parallel transactions

the documentation says that I can send transactions to the public mempool and flashbot mempool in parallel, but if I do this, then in 100% of cases a transaction from the public pool is executed, even if the private transaction has a higher commission. can you help me?

      • What kinds of MEV do major DeFi platforms expose today?
      • Most Rollup L2s promise instant transaction confirmation by having the sequencer commit on including transactions on a first come first serve basis. Does this affect your user base?
      • What countermeasures have Aave and Synthetix introduced, or are thinking to introduce in order to reduce their MEV surface?
      • How would you compare the MEV exposed by an Optimistic Rollup protocol, vs an ZK rollup protocol. Do fraud proofs have any fatal weakness in your opinion?
      • When evaluating an L2 protocol to use, do you take its MEV mitigation measures into account?

Extra Credit: Roast Questions from the Roast Master:
😊 The questions below have purposefully abrasive language to fit the "roast" theme. 😊

  • Why does the Flashbots definition of MEV not include all extractable value such as native EVM fees? It's confusing and wrong—please fix.
  • Can we stop celebrating the gas savings from off chain PGAs? Those gas savings are minimal, <1% of gas usage. (Source: MEV-Explore v0)
  • Can we please stop propagating the misconception that the MEV power hierarchy ends with all-powerful block builders? This is FUD. The power hierarchy is user < bot < block builder < dApp < VM. We primarily need to focus on better dApp designs as well as VM-level MEV minimisation and extraction such as EIP-1559.
  • Can Flashbots leadership tone down concave thinking such as "MEV is fundamental" and "fairness is impossible". We only need good-enough fairness and good-enough MEV minimisation.
  • Can the centralisation risks that stem from Flashbots block proposer whitelisting in the context of Eth2 be properly acknowledged and taken more seriously?
  • Flashbots REV only provides a 5.2% increase in miner revenue. Do you find these REV numbers compelling enough to justify the huge Flashbots effort?
  • Can flashbots.net be friendlier to non-devs as opposed to a redirect to a Github repo?

Incorrect link to pokt.newtork in README.md

The link to pokt.network in README.md is treated as a relative link because it is missing a URI scheme. This brings it to a non-existent file in the repository named pokt.network. I forked and changed the link, but I haven't submitted a pull request, because CONTRIBUTING.md said to submit an issue first.

Flashbot bundle is not included because "isSendToMiners" is false?

I'm trying to send a flashbot Bundle with several transactions. I use the following code to sign and send a bundle:

 const signedTransactions = await flashbotsProvider.signBundle([
    {
      signer: MyWallet,
      transaction: firstTx
    },
    {
      signer: MyWallet,
      transaction: secondTx
    },
    {
      signer: MyWallet,
      transaction: thirdTx
    }]);
    const targetBlockNumber = block.number; 
    const simulation = await flashbotsProvider.simulate(
      signedTransactions,
      targetBlockNumber + 1
    )

    console.log(simulation);
    console.log("bundleHash: ", simulation.bundleHash);

    for (var i = 1; i <= 10; i++) {

      console.log(">>>>>> ", i);

      const bundleSubmission = await flashbotsProvider.sendRawBundle(
        signedTransactions,
        targetBlockNumber + i
      )
      console.log('bundle submitted, waiting', bundleSubmission.bundleHash)

      const waitResponse = await bundleSubmission.wait()
      console.log(`Wait Response: ${FlashbotsBundleResolution[waitResponse]}`)
      if (
        waitResponse === FlashbotsBundleResolution.BundleIncluded ||
        waitResponse === FlashbotsBundleResolution.AccountNonceTooHigh
      ) {
        console.log('Bundle included!')
        process.exit(0)
      } else {

        console.log(">>>", simulation.bundleHash);

        console.log({
          bundleStats: await flashbotsProvider.getBundleStats(
            simulation.bundleHash,
            targetBlockNumber + 1,
          ),
          userStats: await flashbotsProvider.getUserStats(),
        })
      }
    }

The simulation is successful. However, In order to ensure that the bundle can be included, I for loop 10 times to send a new bundle in case the previous bundle fails. It seems that the bundles are not included because they are not sent to the miners(isSentToMiners is false). Why does this happen?

Cannot send private transactions which include an access-list

I am attempting eth_sendPrivateTransaction with transactions which include an accessList (on ethereum/mainnet).

No matter how much I increase the maxFeePerGas and maxPriorityFeePerGas values, these transactions always end up showing "status":"FAILED" on the Transaction Status API webpage (at https://protect.flashbots.net/tx).

Is there any knows issue around this?

Thanks.

An example transaction:
