Atomic Arb bots are making great use of DFlow JIT for onchain searching
Latest strat seems to be:
2 DFlow JIT instructions, each one with 5 candidates (tessera, humidifi x 3, solfiv2) in opposite directions
sent via Jito. if not profitable, doesn't land. no failed tx fees
New signers used each to to avoid getting flagged as toxic flow

@troublor says wait, but I can't. Can't wait.
We are builting an Ethereum debugger with
1) true source-level stepping,
2) near-100% local/state variable inspection, and
3) on-the-fly Solidity expression eval at any step.

Cross-Chain Arbitrage on Uniswap V4
(opportunities available)
I’ve always been curious: how much do prices actually differ between the “same” @Uniswap V4 pool deployed across different chains?
Think ETH/USDC on Ethereum vs on @unichain, @arbitrum, or @base . They’re technically the same trading pair, but entirely separate pools, with different liquidity, fees, and most importantly, prices.
So I built a dashboard to monitor exactly that. It tracks real-time price discrepancies across Uniswap V4 pools on different chains.
Why?
I was curious. I wanted to understand:
- How often do mispricings occur?
- How big are those discrepancies?
- And perhaps most interestingly: how fast are they arbitraged away?
On the same chain, arbitrage between DEXs is well understood. You can create a smart contract that executes a set of swaps atomically, either guaranteeing profit or reverting the transaction. But cross-chain? That’s a different game. Different chains mean different execution environments, timing issues, and gas fee structures. It’s harder to coordinate. It’s also harder to monitor...
What I’ve Built (So Far)
Right now, the dashboard monitors the ETH/USDC pair across four chains in real time. You can visually see:
- Realtime ETH price on each chain
- Size of most recent trades indicated by bubble size
- Max current spread available.
I've only finished it this afternoon and after watching it for 15min I've already spotted a few times where the mispricings are significant.
I want to add more pairs and chains soon (super easy actually) - just don't want to clutter it before getting more feedback and ideas.
I’ve dropped the link to the dashboard in the comments below. If you’ve built a cross-chain arb bot, I’d love to hear how you approached it!
