ArbMe is finally live! Trading platforms stole $1 billion from you in 2025... this year, traders are taking back control. The extension lets you arbitrage your own trades and earn cashback by arbitraging your price impact. A new era is beginning. Trade to Earn.

@hashim20a Yes that's the idea, to find a pool with the deeper liquidity as possible for rebalancing. We have our own in-house technology for that.

@bencirc How feasible it is to get the tokens for rebalancing from other pools without acquiring less slippage to gain more profit? And you guys have built a pool aggregator to get better pricing?

Have you ever heard about the inefficiency of AMMs? When you trade on-chain, you lose money. As a daily Solana user, I make swaps every day. Simpler, cheaper, faster. But I have a crazy statistic to share with you: traders on Solana lost $1 billion in 2025 because of the math. What does math have to do with any of this? An AMM/liquidity pool operates, for the most part, without an order book but using math (x * y = k). This mathematical formula is the core concept behind an AMM. Let's take a simple example: x = USDC y = SOL Market price of $SOL is $100. If I deposit 1,000 USDC, I’ll also deposit 10 SOL so that my liquidity pool has a market price of $100 per SOL (1,000/10 = $100). Now, let's do the calculation (x * y = k): 1,000 USDC (x) * 10 SOL (y) = 10,000 (k). Great so we know the mathematical value our liquidity pool aims to achieve: 10,000. Now let's make a trade of 250 USDC to exchange it for SOL… how much do you think you'll get back? If the price is $100 per SOL, by exchanging 250 USDC you'll get 2.5 SOL, right? Absolutely not! Let's do the math again: 1,250 (1,000 initial USDC + 250 deposited by your trade) * 7.5 (10 initial SOL - 2.5 withdrawn by your trade) = 9,375. 9,375, not 10,000. Whereas: 1,250 * 8 = 10,000. So the liquidity pool will give you 2 SOL instead of 2.5 SOL. You just lost 0.5 SOL. This is what's known as AMM inefficiency. Now the question is: how can you protect yourself from this? Arbitrage. You can recover the value you lost by arbitraging liquidity pools. In this case, if I buy SOL from another liquidity pool and sell it on this one, I’ll rebalance it to 1,000 USDC – 10 SOL and capture the lost value (0.5 SOL). It was by realizing this that we built @arbmesol for the @colosseum. It's an extension that lets you recover the SOL you lose during your trades on Solana as cashback directly into your wallet. Now that you know this and that a solution exists… you're the only one responsible for losing SOL due to the inefficiency of AMMs. Trade to Earn.

@maxekaplan I hope for you the good side at least pays back the bad side haha

@bencirc lol. Been on both sides of that (fat fingering a tx with way too high of a fee and also collecting huge fees on the validator side). Def someone running a command manually (mixing up SOL with lamports), or bot going rogue

Money laundering or a setup error? Either way... this guy paid $55k in fees to transfer $0.08 on solana... Even my bank doesn't charge that much :( 3YHhY3pSjowRqG84oNj5i595KuyAhmd52D8qaVSq3y6hGJBS6UpZc9Wy3jq3Mi3bgWjrkmkv5qf3iDMeE1yM1h8J

If we look at your users 24h top trading volume, they're trading memecoins, not pairs available on propAMMs. Also these tokens often have multiple pools after migrating to pumpAMM, particularly on Meteora DLMM. 2xfHwzvy3FEgLkNNdjH5d3v3ToW4esp5T2Vs4wn5WHkMT9tonhkcjegz8kcWsvwMySTw3yEmUJtMrcTmRjvDAriS

@bencirc @qrazhan_ultd @fomo @arbmesol prop AMMs are tigher than binance on SOL & most of these coins have a single LP pool there is no “arbitrage” that isnt just taking positive slippage from users

Drop some elite ball knowledge, but the topic is trading 👇

@zknadar I guess he didn't want to wait for the next block...

@bencirc Wut?

@brian_smith_0 Running a BAM validator also improve your luck in daily life?

@bencirc Validators running BAM have good karma

@StakingMatthias Having the transaction before it even land on the network is a huge hedge.

@bencirc How do you make sure that nobody else took the arb opportunity?

@seyong @qrazhan_ultd @fomo @arbmesol Numbers don't lie but you have to know how to interpret them... This is sandwich. We do arbitrage.

@qrazhan_ultd @bencirc @fomo @arbmesol men lie, women lie, numbers dont sandwiched.me

@qrazhan_ultd @fomo @arbmesol Just one example 2h ago (4.25 SOL revenue): Trade: 597FojUHNEf6odp4jVkau8BrSNVha3VhCdpjeSbwN1mQsUDoeBxu6wqTy7ygv8dXRPdoxsbDjokQWAssExqPNkEV Arbitrage: 2xfHwzvy3FEgLkNNdjH5d3v3ToW4esp5T2Vs4wn5WHkMT9tonhkcjegz8kcWsvwMySTw3yEmUJtMrcTmRjvDAriS

@qrazhan_ultd @fomo @arbmesol $100 a day for all your users? You should fire this team 😂 If that's really what you told the teams you contacted, we can talk about it... otherwise, you already know. Also: being an aggregator of aggregators does not protect against value leakage on AMMs.

@SunnyDexApp @bw_solana why?

@bw_solana MEV bots quietly crying in the corner rn

200ms slots are on the menu… … Agave v4.2 is going to be the most insane client upgrade in Solana history

@bw_solana Thank god I'm working on Solana... I'd be devastated by this news if I were on another blockchain. Accelerate 🚀

@JET_EUROPA_ Thanks for the support 🫡

@bencirc This man knows what he's talking about, great post Ben!

@mattytay @anza_xyz MEV systems 👋

Solana has taken the hard path, more than any other crypto network. @anza_xyz has spent years doing the difficult engineering work required to push network performance closer and closer to centralized systems, while still preserving a credibly neutral, globally decentralized network. And it’s not just Anza. Eco teams like @Helius, @Rakurai_io, @triton_one, @jito_sol and many others have continuously made improvements across the stack: validators, clients, networking, block propagation, RPC infra, MEV systems, tooling, and dev experience. That work compounds. And over time, it has made @Solana increasingly competitive with centralized alternatives without abandoning the core properties that make crypto matter in the first place. Meanwhile, many newer systems like L2s, appchains, Hyperliquid-style architectures, or new corpo chains have taken shortcuts (or have just stagnated completely like Ethereum L1 or Bitcoin). The real question is whether maintaining decentralization actually matters from both an economic and regulatory standpoint. I strongly believe it does long-term. I believe in @toly’s vision of a global financial network that cannot be shut down, is open to anyone, and allows assets of all kinds to find price discovery in a far more efficient and permissionless way than today’s financial system. That vision is much harder to build. But if crypto succeeds at scale, I believe the world ultimately converges in that direction. Hats off to everyone working at Solana’s infra layer.

@fomo is now live on ArbMe 🤯 Keep trading as usual and earn cashback on your solana trades when you leave value behind! I'd love to hear what @rasmr_eth and @PaulErlanger think about that.

@m_hbbrd Bringing back the value to traders 🫡

Super cool concept!

@0xbenbottle @colosseum @solana Everyone deserves a good cashback.

@bencirc @colosseum @solana everyone loves a good cashback

The @Solana Frontier Hackathon product directory is live!🏔️ Frontier was the largest crypto hackathon ever & one of the largest in tech history with 2,857 submissions. Winners and Colosseum's next accelerator startups will be announced next month. arena.colosseum.org/projects/explo…

Today I gave a pitch on @Circular_fi and our ambitions with @arbmesol at @theBlocksSummit. It's always an incredible experience to pitch as a founder. But pitches are rarely just pitches, we're mingling with other players in the blockchain space. It doesn't matter if the other founders are from Solana, Ripple or Ethereum… sharing ideas and understanding other ecosystems is always the best part of this kind of event. Exploring new ideas is the key. I think I love it… @SolanaEvents, where's your next event?
