Built with Ghost 👻 I used @tryghostxyz to write the indexer directly in Solidity. Why? ✅ Zero context switching ✅ Faster indexing ✅ Easy access to contract state

1/4 Sharing the latest sandwich <-> validator data for epoch 805. We also compared epochs 789 and 805 Marinade 🛡️ pools are increasingly getting gamed by sandwiching validators Link to spreadsheet at the end of the thread

We've added a download tab that links to validator-specific Solana sandwich data, organized by epoch Each file breaks down sandwich rates + stake distribution per validator Early signs of improvement, as Marinade removes sandwiching validators. We will continue to track these

We're excited to integrate with Ghost to power our dashboard, platform analytics, & more to come. Mint badges. Stack hydropoints. Earn tokens.

This might be controversial, but your transactions should be able to fight back against malicious sandwiching validators. I built a simple program to do exactly that. You can't know at runtime if slippage is natural market movement or a sandwich attack. But if your swap lands

1/7 Almost a month has passed since epoch 805. Sharing the latest sandwich <-> validator data for epoch 819 Marinade 🛡️ removed the worst offenders from their stake pools, which has had a significant impact in reducing sandwich attacks on Solana

Our new Solana mainnet validator Ghost is live. If you find our public data & research useful, please consider delegating to support our work. stakewiz.com/validator/HJmf…

Big thanks to Aero for delegating stake to our brand‑new validator! Your trust fuels Sandwiched.me by Ghost, bringing open MEV analytics and data that helps keep the Solana ecosystem transparent!

You might have heard about "Prop AMMs" on Solana We built a lightweight dashboard: - streams realtime data from 2 Prop AMMs - plots continuous-depth curves => can see sub 1 bps - cross-pool router simulator => can see sub 0.5 bps

Now also tracking Tessera V and HumidiFi, based on popular demand Pretty cool to see 0.5 bps at 50 SOL

We added a validators tab! - Track each validator’s sandwich rate over time. - Filter by “blocks produced” to focus on validators with at least X blocks in the last 30 days. - Click a validator to compare its sandwich rate to the cluster median

Gather data Identity problems Fix problems Repeat!

A month has passed since epoch 819 Here’s the latest sandwich ↔ validator data as of epoch 835, along with an updated threshold The 30d cluster median sandwich rate is now 1.26%. By lowering the threshold from 15% to 5% (about 4x the cluster median), we get this new chart

You can now see per-validator daily sandwich block production alongside the existing 30-day rolling charts to clearly identify any trends

Thanks JPool for welcoming us into the Community Good program and delegating to our Ghost validator. Your support helps power Sandwiched.me -- the Solana MEV Data Hub keeping the ecosystem transparent ❤️

1/ Big update for Sandwiched.me: We’re rolling out Sandwich Detector v2 – a major step forward in catching malicious actors who profit from extractive sandwich attacks

Shout out to DynoSol for supporting what we’re building at sandwiched[dot]me by staking with our Ghost validator 🙏

Validator Spotlight: GHOST Let’s talk about Validator Ghost by Ghost , a team tackling one of Solana’s trickiest problems: MEV transparency. 🛡️ With sandwiched.me, Ghost exposes sandwich attacks, arbitrage, and other hidden behaviors, turning dark corners of
