The article(attached) discusses new tools and infrastructure being built to track, measure, or minimize MEV on Solana — things like: • Transparent block building • Better incentives for validators • Protection against users getting taken advantage of What is MEV? MEV stands for Maximal Extractable Value. It refers to the extra profit that someone — usually a validator, block producer, or even a bot — can make by reordering, inserting, or excluding transactions in a block before it gets finalized. Think of it like this: Imagine you’re waiting in line to buy concert tickets. You’re second in line. But the guy working the ticket booth realizes he can make more money if he lets someone else cut in front of you because that person offers more money for the same ticket. That’s what MEV is — profiting by manipulating the order of transactions. Why Does MEV Happen? Some transactions on blockchains (like trades, arbitrage, or NFT mints) are time-sensitive and profit-driven. Whoever gets there first can make more money. MEV arises when insiders (like validators or bots) take advantage of this by: • Front-running: Seeing your transaction in the mempool and sneaking in their own right before yours. • Back-running: Placing a transaction right after yours to benefit from its effect. • Sandwich attacks: Inserting two transactions — one before and one after yours — to profit off your trade. Why is MEV a Big Deal on Solana? On Ethereum, MEV has been widely studied because of the open mempool (where pending transactions are visible before they’re confirmed). On Solana, it’s a bit different because Solana doesn’t have a traditional mempool — but MEV still exists, just in other forms, often more validator-centric due to the chain’s architecture and speed.

Dealwire.TECH Deal of the Week — Mesh ($75M Series C, $1B valuation) https://www.meshpay.com/ Crypto’s next chapter isn’t about speculation — it’s about payments infrastructure. Mesh’s $75M Series C at a $1B valuation signals a clear shift in investor conviction: capital is rotating from trading and token-centric narratives into real-world transaction rails. Mesh is building what many in the industry have talked about, but few have executed: a global crypto payments network that connects exchanges, wallets, and payment providers into a single interoperable layer. Consumers can pay with any supported digital asset, while merchants settle instantly in stablecoins or local fiat — no volatility risk, no wallet management, no fragmented integrations. The company’s asset-agnostic SmartFunding technology abstracts away blockchain complexity, routing “any-to-any” payments across chains and liquidity pools. The result is a horizontal payments layer that targets embedded deposits, remittances, and high-value cross-border commerce — areas where legacy card rails struggle with FX leakage, chargebacks, and delayed settlement. Led by Dragonfly, with participation from Paradigm and Coinbase Ventures, the round reflects strong alignment around an infrastructure-first thesis. Mesh’s ambitions — $1B in revenue and $1T in transaction volume — place it firmly in the category of next-generation global payment networks, not fintech tooling. Bottom line: If crypto is going to reach mass adoption, it won’t look like exchanges — it will look like invisible, instant payments embedded everywhere. #DealOfTheWeek #DealWire #CryptoPayments #Fintech #PaymentsInfrastructure #Stablecoins #Web3 #DigitalAssets

"Now that USDT and Bitcoin are natively interoperable on lightning, the circle has gained tangents. With USDT on lightning, each party to a payment, the payer and the recipient, can choose whether to use Bitcoin or Tether on their own end, and neither depends on the other's decision. A customer can pay in Bitcoin and the merchant can receive USDT, or the customer can pay in USDT and the merchant can receive Bitcoin. Or they can both use the same asset, it doesn't matter. Once both assets are native to lightning, they become automatically, frictionlessly, interchangeable." ~ Roy Sheinfeld Tether's integration with the Lightning Network goes beyond a mere technical enhancement—it has the potential to transform global financial transactions worth billions. Roy Sheinfeld’s article examines how this could accelerate adoption, challenge established payment systems, and navigate regulatory and technical uncertainties. The key question: will this strengthen Bitcoin or make it more vulnerable?

✨ Today we're launching our a new kind of smart contract wallet ✨ While the crypto industry obsesses over smart contract audits and zero-knowledge proofs, 80% of losses come from something far simpler: people losing access to their own wallets or having the wrong people gain access. After 4 years building at every layer of the smart contract wallet stack and powering wallets at scale (like Coinbase Wallet), we at Stackup have seen firsthand how access control failures destroy billions in value. We knew we had to solve this fundamentally. Today, we're launching our keystore wallet -- the first to truly deliver enterprise-grade security without sacrificing usability. Our architecture stores your entire access policy (signers, permissions, spending limits, recovery methods) as a single Merkle tree root hash onchain. Whether you have 5 signers or 500 permission rules, the gas cost stays constant. It's so efficient that we subsidize gas fees entirely. What this means for organizations: • Privacy by default - Your signers and org structure remain confidential, not exposed onchain like traditional multisigs • No coordination overhead - Set spending limits, time delays, and department permissions that execute automatically • True multi-chain - Update your policy once, it syncs across all chains instantly • Future-proof - Add new authentication methods without changing your wallet address For technical founders and teams managing treasuries: you no longer have to choose between security and usability. Bank-grade access controls are now practical for daily operations.
