Introductions 👋

[nikki]

Hello! I’m Nikki, a cryptography researcher @ Flashbots. I’m interested in any part of the MEV landscape where cryptography and theoretical computer science research can make a positive impact. Some specific interests of mine are SUAVE, private auctions, proof systems, homomorphic encryption techniques, and porting techniques from classical math/cs research towards the frontier.

Hey everyone,

Been in DeFi for a few years. Ran Pangolin on Avalanche during the last bull market and after handing it back to the community I started getting more involved in data analysis and have recently started working on an Almanack for crypto Trollip’s Degen Almanack

As part of researching the MEV section I’ve fallen down the rabbit hole and become a wee bit obsessed with MEV. Think it’s probably the most interesting subject in crypto atm. Looking forward to learning more from the community.

[SebastianF]

Hi! I am Sebastian. I am a professor at Technical University of Darmstadt and a researcher at PolyCrypt. I mainly do research in cryptography. I am currently working on side-channel resistant cryptography (typically against DPA) and cryptographic tools to improve blockchains. For example, last year we developed a new threshold encryption scheme that has some nice applications for encrypted mempools. Since I recently got quite interested in 'TEEs and how to protect them against physical attacks (side-channels, faults) and also more advanced threads such as trojans, I found this forum here.

Hi! My name is Andrew.

I am a software developer and am learning about web3 and Blockchain, specifically for Ethereum based chains.

I have a specific issue that I am hoping someone here can help me with…

1. I use PulseChain, an Ethereum fork started in May 2023, Chain Id 369.
2. Due to my own stupidity/carelessness, I believe (though I’m not entirely sure) that one of my wallets was compromised (seed phrase exposed).
3. The wallet is now empty except that it was used to initiate a stake…
4. The stake ends in a few months, so I am concerned that a monitoring bot will automatically transfer my coins…
5. Someone suggested that with Flashbots I can create a JavaSript that will bundle multiple transactions (ie. unlock stake and transfer coins to a safe wallet) so that they are included into a single block and thus preventing them being stolen…

Is the above correct?
Can someone in the community assist me?

Hello my name is Geo. I recently got a wallet compromised, and am looking to withdraw funds from an app that’s connected to my wallet. RabbitX specifically.

I learned you could use MEV to bundle the claim and send transactions I’d need to claim the funds for withdrawal and send them to a new account at the same time.

The hackers got me by messaging me on X about a community manager role, sending me to the ‘hiring manager’ on discord, where they asked me to download a game from [https://] playshowdown [dot] xyz. Nothing would happen when I downloaded it, and I tried on my MacBook Pro and Desktop. The mac app asked for a password. I entered it. Then they got access to my google account and my wallet keys.

I have some NFTs left over in that wallet still but they’re not nearly as important as the money. Let me know if you can point me in the right direction.

Here’s my x account: @geoppls

gm!

I’m Antoine, I’m 22, and I’m currently working for Spearbit as a Rust Backend Engineer, I was previously working for Formal Land, were I was doing Formal Verification. I also did some previous CTFs and Web3 competitive audits on the side (mainly in Solidity, although I’m highly interested in leveling up in Rust)

I have a background in cybersecurity and some development skills. I know some people who are trying to do MEV, and it’s a super interesting area. I recently joined the forum to learn more about the products that are being built at Flashbots.

[olgathepolga]

Hey everyone, I’m Olga! Excited to learn more and engage with you all. I come from a background in strategy, operations, and product management, always working between tech and commerce. I’m a bit of a n00b to the deep mechanics of MEV, however here to explore and I’m keen to learn more about how to make the blockchain ecosystem fairer.

• Which Parts of the MEV Landscape Are You Interested In?

I’m particularly interested in the economic and governance aspects - how it shapes incentives for different players in the ecosystem and how we can design fairer, more efficient systems. Also, I’m keen on exploring SUAVE and how it might redefine transaction execution.

• Are You Involved in Any MEV-Related Initiatives or Projects?

Not yet, but eager to contribute! My experience could be valuable in scaling initiatives, engaging stakeholders, and helping make MEV more understandable for a broader (non technical) audience.

• What is Your Experience with Flashbots Products and Research?

I’ve been diving into the research and following Flashbots’ work on MEV-Boost, SUAVE, and transaction ordering. While I haven’t been directly involved in using these products, I’m keen to learn from those who have and contribute where I can.

• Are You Part of Any Other Communities in the MEV/Ethereum/Crypto Space?

I’ve been following Ethereum governance discussions and staying informed on DeFi and Layer 2 scaling developments. Open to getting more involved in MEV-focused groups!

What is Your Favorite Robot?

Wall-E! A small, efficient machine that thrives in a chaotic environment while being curious and resilient - seems fitting for the MEV space.

Excited to meet you all and become a part of the community!

[Merso]

Ave!
My name is Merso and I work as a Rust engineer, first in TradFi, then in IT and DeFi/MEV, today as a searcher. I don’t contribute to public MEV projects yet, but I hope to soon.
I write some content about MEV in general, which you can find on my X profile: 0xMerso.
Thanks for all the insightful Flashbot letters! See you onchain, bye!

[Manzier]

Hello! I go my Manzier, which is a nod to the show Seinfeld. I have 25 years of IT experience with a heavy focus on networking and management.

I have some serious add and love to learn. Been doing a deep dive on aave liquidations. Lots of references to flashbots in my research so figured I better take a tour and see if I fit.

[ironcrypto]

Hi Flashboys!
My name is Steph. I spent years in the TradFi/DeFi crossover—building real-time agents, modeling latency arbitrage topologies, and reverse-engineering chaotic order flow as alpha signals. But what fascinates me isn’t just the mechanics—it’s the meta-game: how systems hardcode power, and how protocol design is value design. That’s why Blanc’s work on liquidity primitives hits different.

I like to break things (responsibly) with a team that treats liquidity as a protocol-first battleground. If you’re down to debate MEV’s endgames or architect anti-fragile systems—reach out!

PS: My happy place? Optimizing searcher-builder collusion resistance while blasting Wu-Tang
PPS : My current nightmare fuel? CFMMs becoming the PFOF of DeFi—where LPs subsidize MEV bots instead of retail.

Hey all, I’m Chris – working on a modular arbitrage system using flashloans + real-time graph analysis

Been deep in DeFi for a while and recently finished building a full-stack arbitrage engine that operates across major DEXs using live subgraph data, memory-only computation, and flashloan-enabled execution. Posting here to share what we’ve built and how it works — not selling anything, just open to feedback or insight from folks who’ve worked with Flashbots, MEV, or real-time execution flow.

---

System Summary

We designed this to be clean, modular, and precise — focused on reliability more than speed.

• Flashloan-Scoped Token Universe
  Only includes tokens available for flashloans (Aave & Balancer). All liquidity/pairs outside this scope are ignored.

• Graph-Based Execution Planning
  We construct a weighted directed graph of token pairs based on normalized ETH-equivalent liquidity.

• Algorithmic Pathfinding
  Uses Bellman-Ford, Dijkstra, and Floyd-Warshall to locate cyclic trade paths with net-positive outcomes.

• Validation Process
  Every path is filtered to meet:

  • ≥ 0.1% profit margin
  • ≥ $5,000 projected net gain (based on actual available liquidity)

• Execution Pipeline
  Valid paths are grouped into gas-aware bundles, then encoded and wrapped into Flashbots bundles with MEV bribes if needed.

---

Tech Details

• Async Python (no database — all state in memory)
• Subgraph ingestion from Aave, Curve, Balancer, and Uniswap
• ETH/USD normalization via Chainlink + fallback
• Internal plugin architecture for liquidity fetchers
• Final execution logic built around ExecutionLayer.sol (atomic swap/bundle support)

---

Current Status

System is in test-mode running scans every 45 seconds. Final stage involves tuning execution gas usage and bundle construction strategy. Not monetizing it right now — just testing edge cases, robustness, and seeing how it behaves under different liquidity conditions.

---

If you’ve worked on Flashbots pipelines or have experience with slippage-aware execution bundles, I’d be interested in learning more. Cheers.

Hi everyone! I’m Sean Sweeney, a blockchain engineer. I’ve worked across the stack on smart contracts, dApps, and security.

I’m particularly interested in the MEV space from a protocol perspective—especially builder and relay dynamics, and how we can make extraction safer and more transparent.

I’ve used Flashbots tools for simulation and analysis, and I’m currently exploring how to contribute more directly to the BuilderNet ecosystem.

Favorite robot? Gotta go with R2-D2—small, smart, and always clutch in critical moments.

Looking forward to learning and collaborating with folks here.

Hello. I’m just a layperson who’s interested in using Flashbots Protect with Metamask; I cannot add it to Metamask because it says that the chain ID is already associated with a network. How can I get past this problem?
