MEV on other chains

[Jefferson111]

Love to see articles about MEV on other chains (Solana, Osmosis, Thorchain, Acala, Ziliqia, Moonriver, etc). Like how do ppl arbitrage over there? Do they do it as validators or as solo hunters? Which chain is the most profitable? What kind of competition are there on those chains?

For example in Solana, we hav ppl running nodes, inspect ppl's arbitrage txns and front run them by spamming and broadcasting transactions. Would love to see details on what protocols these ppl are hunting on (example jup.ag, serum), what tricks they employ to effectively spam the network (due to Solana NFTs, there hav been lots of changes made to combat spam) and possible ideas on how to do better.

Or on Osmosis, whereby transactions fees are free for swaps. Although the TVL is much smaller, how is arbitraging faring over there? How many and which validators are arbitraging. And how would it fare over there for validators (if there is a transaction fee bidding war) when the reward system is different from Ethereum? Would be great to see articles and on-chain analysis on that too.

Thanks
