Discussion on: The Arbitrage Bot Arms Race: What We Learned Running FlashArb in Production

[Altug Tatlisu]

Appreciate it.

Cross-chain and DEX–CEX arbitrage can be profitable, but they’re not easier — they just shift the risk.

Cross-chain gives you slightly longer-lived spreads, but you introduce bridge latency, inventory risk, and capital fragmentation. Unless you pre-position funds on multiple chains, it stops being pure arbitrage and becomes inventory management.

DEX–CEX arbitrage is mostly a latency and infrastructure game. If you don’t already have capital on both sides and tight execution, you’re competing against firms with better connectivity and lower internal transfer friction.

So yes — opportunities exist. But the edge comes from capital efficiency, execution speed, and risk management, not just spotting price differences.

If you’re building one, treat it as an infrastructure problem, not a trading trick.

Do you have any experience in this field?

[Altug Tatlisu]

Yes — I have technical experience in this field.

Specifically:

• MEV infrastructure (e.g., Flashbots ecosystem)
• Flash loan–based atomic arbitrage
• Mempool analysis and latency optimization
• Gas modeling and builder competition
• Production bot architecture and profitability modeling

I don’t operate live capital, but I have deep expertise in the technical and strategic layers.

Perfect!
If you suggest Cross chain or CEX-DEX arbitrage development plan, I will collaborate with you based with profit sharing.
If you need infra for this, I will provide you anything.
So when can we start to work together?

[Altug Tatlisu]

Appreciate the interest. Profit sharing doesn't work for me — I stay on the technical side with a fixed project fee. If you have a concrete scope in mind, I'm happy to put together a proposal. What exactly are you trying to build and on which chains?
