the specific technical headaches blocking your DeFi P&L

Uniswap v4 has officially launched on more than 10 different chains, and it’s really making a splash! One of the coolest things about this update is that it lets competitors roll out hooks that are going to be pretty hard to outdo unless they make some significant changes to their EVM and accounting systems. Exciting times ahead! Let’s be real--the costs of "learning in production" can be pretty serious. If you run into any bugs with hooks, it could seriously throw off pool safety and mess with your cash flow. Plus, those migration delays? They can really chew up precious time when it comes to keeping liquidity flowing.
Take a look at the Uniswap blog to get the scoop!

Hey there! So, Ethereum's Pectra just made a big leap by doubling the blob capacity, all thanks to EIP-7691. Pretty cool, right? But there's a catch--calldata has gotten pricier, thanks to EIP-7623. Just something to keep in mind! If you’re not going with a blob-first batching strategy, you could end up spending way too much on data availability for months on end. This might lead to some serious confusion about your cost of goods sold and transaction costs. Plus, it could really mess with your fee estimates right as you’re starting to grow. Yeah, that’s definitely not what you want to deal with when scaling up! If you want to dive into the specifics, check out the details over on the Ethereum blog. You'll find everything you need to know there!

So, here’s the deal with Solidity: there’s still some gas leakage happening. A lot of teams are sticking to storage locks for reentrancy and doing manual memory copies. The kicker? This can result in 5-30% of gas being left on the table in those crucial hot paths, even when there are tools like EIP-1153 and MCOPY available to help out. It’s a bit of a missed opportunity, wouldn’t you say? If you're looking for more details, check out EIP-1153. You'll find a bunch of helpful information there!

The smart wallet experience is really starting to take off, especially with options like 4337 and 7702. But here's the thing: account abstraction (AA) stacks can get pretty scattered pretty quickly. If you don’t handle gas sponsorship the right way, it could really impact your unit economics. And if you just sit back and do nothing, you might end up slowing down your growth because of the hassle with onboarding. For more details, check out the Ethereum blog here.

Hey there! So, the world of MEV and intents is really shaking things up lately. With these new CoW-style solver auctions and the whole SUAVE/Rollup-Boost preconf situation, the game is definitely changing when it comes to who holds the execution advantage. Exciting times ahead! If you’re still using basic RPCs or those “best-route” DEX aggregators, you might not realize it, but you could be putting a bit of a strain on your users. Check out The Block for more details! It's a great resource if you're looking to dive deeper into the topic.

Hey there! So, restaking is officially happening now. We’re seeing slashing in real-time, AVS working on Layer 2 networks, and some fresh new incentives that have been revamped. Exciting stuff! Hey there! If your setup relies on oracles, decentralized applications, or automation and isn’t ready for AVS economics or possible slashing events, you might run into some issues. Basically, you could find that your protocol-level service level objectives (SLOs) and yields start to go off-kilter. So, it’s definitely something to keep an eye on! If you’re curious to learn more, definitely take a look at Outposts. They’ve got all the details laid out for you!

what this costs in deadlines and market share

• Missed opportunities: Thanks to the v4 hooks and those ongoing clearing auctions (CCA), it’s become super easy for competitors to boost their liquidity. If you hold off for just a few months, you could end up facing some pretty tricky price discovery issues, a split total value locked (TVL), and might have to ramp up liquidity incentives just to stay competitive. (blog.uniswap.org).
• Cost surprises: So, after the Pectra update, I've noticed that blob fees usually dip pretty low when things are calm. But when the action picks up, they start acting a bit funny. Those outdated limits on max_fee_per_blob_gas really aren’t doing the job anymore. In finance, things are a bit all over the place lately. We’re noticing some unexpected fluctuations in our cost of goods sold, which is a bit puzzling. On top of that, our procurement team is having a tough time forecasting costs. Not to mention, the margins on our sequencers seem to be pretty inconsistent too. It’s quite the juggling act! (alchemy.com).
• Security regression: Between 2025 and 2026, we saw a pretty big spike in crypto thefts. There were some really massive incidents where people lost a ton of money due to wallet hacks. MEV and bridge attacks are really just exploiting small weaknesses in the process. Just one little mistake with reentrancy or some oracle problems can really set you back, potentially wiping out months of progress and funding. (chainalysis.com).
• UX churn: If you overlook account abstraction and passkeys, you might find yourself missing out on those sweet conversions. Wallets that provide one-click swaps and gas abstraction are definitely going to have the upper hand. Your competitors offering "free swaps" are likely to have an advantage when it comes to getting people on board and keeping them around. (blog.uniswap.org).
• DA and prover tax: Nowadays, ZK proving backends and data availability options aren't something you can just set and forget. You really need to stay on top of them! If you're not on top of the latest tech like Plonky3, GPU acceleration, or making sure you’ve got those multi-DA backups in place, you might find yourself dealing with higher latency and costs. And let's be real, that’s going to hit your bottom line pretty hard. (polygon.technology).

7Block’s technical‑but‑pragmatic methodology that ties Solidity and ZK to ROI

We're not just here to throw definitions at you. Instead, we roll out audit-approved, procurement-ready systems in just 90 days. These systems really boost your go-to-market efforts and help you make a genuine impact. Ready to jump right in? Let’s kick things off here:

1) Blob‑first DeFi architecture (post‑Pectra)

• Blob Budgeting: Alright, let’s go ahead and tweak those batchers for the new 6-target/9-max blobs, plus we’ve got that updated base-fee curve to consider. Time to get things dialed in! We're adjusting our batch windows to ensure everything runs smoothly during those busy times, and we're also making sure that any fees drop off quickly once the rush subsides. On top of that, we're also putting some safeguards around max_fee_per_blob_gas to keep any wild spikes in check. (blog.ethereum.org).
• Calldata minimization: Basically, we want to switch things up so that data availability (DA) is handled more through blobs instead of calldata by default. We're planning to roll out some estimators that are ready for EIP‑7623. And just in case things get a bit busy or if blob lanes aren’t available where you are or when you need them, we've got your back with a backup option using multi‑DA--kind of like what you’d see with Celestia Blobstream. (blog.ethereum.org).
• Finance handoff: We’re working on creating a simple internal cost model that your CFO will find easy to understand. We’ll break down the blob gas costs for each batch and show you how they look when averaged out per transaction. Plus, we’ll throw in some different scenarios to illustrate how utilization and decay play out.

Gas-Optimized Solidity You Can Measure

• Transient Storage (EIP-1153): We're making a little change here by replacing those SLOAD and SSTORE reentrancy flags with TLOAD and TSTORE. With this update, we're slashing the gas cost from about 7,100 down to roughly 200 gas per call path! Pretty amazing, right? Just to play it safe, we're also putting a cap on transient-slot usage. This way, we can steer clear of any sneaky denial-of-service patterns. Take a look at it here: (eips.ethereum.org).
• MCOPY for Hot Memory Paths: We’ve decided to revamp our marshaling and encoding loops to make use of MCOPY. It’s pretty efficient, costing around 15 gas plus an additional 3 for every 32 bytes in length. This helps us ditch those frustrating word-for-word copies and lets us save some gas, too! Check out the full scoop right here: (eips.ethereum.org). You’ll find all the juicy details waiting for you!
• ERC-6909 for Internal Accounting: With our latest v4 hooks and vault routers, we've decided to roll with ERC-6909 claim tokens rather than sticking to custom scripts. It's a pretty smooth upgrade! This basically boils down to smaller bytecode, which means lower transfer costs and safer approvals for operators. Pretty neat, right? It's quickly turning into the preferred way to handle async flows in Uniswap v4. Curious to dive deeper? Check it out here: (docs.openzeppelin.com). You’ll find a ton of great info waiting for you!

3) Uniswap v4 Hooks That Really Make a Difference

• New Hooks We’re Introducing:
• Inventory-Aware Fee Hooks: These clever little hooks adjust fees by keeping an eye on the pool’s inventory and using info from external oracles. This approach lets us boost the LP APR while keeping any unwanted flow at bay.
• Async Settlement with 6909 Claims: We're taking a different approach by splitting the swap input/output from the settlement process. Check this out--this awesome setup uses CoW solver fills to steer clear of those annoying sandwich attacks! (docs.openzeppelin.com).
• CCA Integration: This feature makes it super easy for us to launch liquidity for new markets by using on-chain auctions. Take a look at this: blog.uniswap.org. You might find some cool updates there!
• Security Guardrails: We've really put a lot of thought into keeping everything secure. We're focusing on isolating hook storage, making sure to avoid any callback mishaps, and we’re using fuzz invariant nets to guarantee that there aren’t any negative deltas. This way, we can also keep fee monotonicity under control.

4) MEV Protection and Intent Routing

• Default: For those sensitive flows, we go with solver-based execution (CoW). Basically, we run some pre-trade simulations and handle transactions in batches to avoid any backruns. If you’re using L2s that are rolling out Flashblocks or Rollup-Boost, get ready for some seriously speedy preconfirmations, often in under a second! This means your experience will be way smoother, and the best part? You still have that added layer of replay protection. (theblock.co).

If you're working on your own L2 or appchain, you’re really going to appreciate Rollup-Boost. It does a fantastic job of keeping builders separate, which makes it way easier to prioritize things. We’ve set up a few guidelines to manage harmless MEV, making sure that our users don’t feel any negative effects. (flashbots.net).

5) Smart Wallet (AA) Without Burning Unit Economics

Alright, let’s break it down: when you add 4337 and 7702, it looks like we're gonna need to dive into those sponsor policies. This means we should pay attention to things like spending limits for each feature and each user. Also, using passkeys on Layer 2 with P-256 precompiles (kind of like the 7212 style) could seriously help reduce drop-offs. Let’s also make sure we avoid any gas-sponsor madness by staying on top of our risk budgets and thinking about surge pricing. If you want to get into the nitty-gritty details, just click here. So, when we talk about integration, we’re really excited about this integration kit we’re working on. It’s got these awesome module-based accounts (we're using ERC-7579 in our supported setups), plus some cool paymaster economics dashboards. And the best part? You won’t have to worry about being locked into any specific vendor!

1. ZK That Fits Your Timing and Wallet.

• Proving Stack: We really like to use Plonky3-based flows whenever possible! To help reduce those tail latencies, we tap into GPU primitives like NTT and MSM. Plus, we’re using a pipeline for witness generation, and we're mixing in that Yoimiya-style partitioning method too. It really helps keep things running smoothly! Oh, and just so you know, we'll be testing your circuits a bit before we really get into it. Take a look at this link: (polygon.technology). You won’t want to miss it!
• Choosing a zkVM: So, depending on how your program is set up and the type of hardware you’re using, we’ll explore some options like SP1, Risc Zero, or zkMIPS. We've seen some really exciting performance improvements lately--like anywhere from 6 to 20 times better--thanks to the latest stacks! If you’re curious for more info, check this out: (zkm.io).

7) Restaking‑aware Infra Planning

• Operators and AVSs: Go for multi-AVS operators that really take their slashing discipline seriously. Don’t forget to set aside some budget for those fee buyback programs and Rewards v2! It’ll help ensure that your AVS income aligns well with your service SLOs. It’s a smart move to keep everything in sync! When you're diving into L2, it definitely makes sense to explore some multichain AVS options. If you’re curious to learn more, head over to outposts.io and check it out!

8) Security Hardening with Measurable Coverage

Alright, let’s get into some heavy-duty stuff! We’re talking about differential fuzzing at hook entry points, which is pretty cool. We’ll also be running some tests on storage layouts and properties to make sure our upgrades are safe. And don’t worry, we’re simulating potential price-oracle manipulation and even testing out scenarios where bridge messages might get replayed. It's all about staying ahead of the game here!

• We’re all about being open and honest when it comes to security. That's why we like to get a head start and check out the project ahead of time with our partners or any company you have in mind. We're working hard to get a full "audit-ready" package to you well before the deadline. Hey there! If you're curious about our security audit services, feel free to take a look at the details here. We’d love to share how we do things!

1) Swap out reentrancy guards for transient storage

Reentrancy guards can really throw a wrench in our code sometimes, making things a bit more complicated than they need to be. They can definitely lead to some frustration! A better way to handle things is to go with transient storage instead. It just makes the process a bit easier! This approach keeps your code tidy and efficient, all while steering clear of problems that can come up with reentrant calls.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.24;

// Gas-lean reentrancy guard (EIP-1153)
abstract contract TReentrancyGuard {
    // slot key = keccak256("reentrancy.lock")
    uint256 private constant SLOT = uint256(keccak256("reentrancy.lock"));

    modifier nonReentrant() {
        assembly {
            // if TLOAD(SLOT) != 0 => revert
            if tload(SLOT) { revert(0, 0) }
            tstore(SLOT, 1)
        }
        _;
        assembly { tstore(SLOT, 0) }
    }
}

So here’s the deal: TLOAD and TSTORE usually cost about 100 gas, but when it comes to SLOAD and SSTORE, you're looking at costs that can skyrocket into the thousands. It’s a pretty big difference! In those busy spots, this is clearly the best opportunity we have after Dencun and Pectra. If you want to dive deeper into the details, just click here. Happy exploring!

2) Use MCOPY for Bulk Memory Moves in Routers/Encoders

If you need to manage large memory transfers easily in routers or encoders, then MCOPY is definitely the way to go! It's built to help you make those moves quicker and easier, so you can tackle more things without all the fuss.

Let me give you a quick rundown on why MCOPY is a great pick:

• Boosted Performance: With MCOPY, memory operations are a breeze! You'll notice that things are running faster and your CPU isn’t working as hard when you’re dealing with those hefty data sets.
• Super Easy Integration: You can just plug it in with your current systems without any hassle, so there's no need to deal with complicated setups to get started.
• Super Versatile: No matter if you're dealing with routers or encoders, MCOPY has your back!

How to Use MCOPY

Ready to dive into MCOPY? Just follow these easy steps to get rolling:

1. Figure Out the Data: Take a moment to identify which memory areas you want to transfer. 2. Use the MCOPY Function: Go ahead and make sure you use the right syntax to kick off the memory copy process. Here's a quick example:.

mc_copy(source_address, destination_address, size);

3. Double-Check the Transfer: Make sure to verify that your data made it over smoothly and that everything's in order. It's just good practice to catch any hiccups early on!

Tips for Success

• Start with Smaller Datasets: Before jumping into larger transfers, it’s a good idea to test the waters with smaller datasets first. This way, you can make sure everything is running smoothly before going all in.
• Keep an Eye on Performance: As you're transferring, make sure to watch the system load and performance. This way, you can spot any hiccups or bottlenecks along the way.

With MCOPY, moving large chunks of memory becomes super easy! Jump in and discover just how simple memory management can really be!

assembly {
    // mcopy(dst, src, len)
    // gas ≈ 15 + 3 * ceil(len/32) (+ memory expansion)
    mcopy(add(resultPtr, 0x20), add(bufPtr, 0x20), dataLen)
}

So, here’s the deal: it replaces the repeated MLOAD/MSTORE operations, which means you’ll see a quick drop in gas costs for each call. Pretty neat, right? (eips.ethereum.org).

3) Uniswap v4 Async Settlement with ERC‑6909

• Pattern: Alright, so here’s the deal--when your hook isn't quite ready to settle yet, just go ahead and mint some ERC‑6909 “claim” tokens to rack up those credits. Then, whenever you’re finally ready to settle, you can just burn those tokens. Easy peasy! By doing it this way, you can avoid any external transfers while the hook is happening. That really helps to minimize any potential hiccups, plus it fits in perfectly with the CoW solver fills. If you're curious about the details, feel free to take a look here.
• Tooling: You can totally take advantage of OpenZeppelin’s ERC-6909 implementations. They’re really useful and come packed with options for metadata and supply, so you can customize them just the way you need! If you want to get into the nitty-gritty details, check it out here.

4) Blob Budgeting After Pectra

Alright, so here’s the scoop on the parameters we’ve gotta lock into the estimators: we're shooting for around 6 blobs per block, but we can stretch it to a max of 9 if needed. There's a fresh twist on the base-fee update--it’s asymmetrical this time around! It looks like we’re expecting around +8. It’s about 2% when it’s completely full, and roughly around -14. 5% when it’s empty.

Hey team, just a quick heads-up! Let’s keep a lookout for operations. If we see utilization creeping above our target for an extended period, we should definitely let the team know. Thanks! Let’s keep things smooth by increasing the batch frequency instead of just cranking up the batch size. This way, we can avoid any sudden spikes in the base fee. (blog.ethereum.org).

1. MEV-aware Orderflow
   First off, when you're diving into swaps that really depend on leverage and health factors, definitely kick things off with CoW's solver network. It's a solid choice! And hey, don't forget to have a backup plan ready to go--having access to those deep liquidity pools can save your skin if things get a little shaky. To enjoy a fast and seamless experience on supported L2s, go ahead and set up those Flashblocks preconfirmations based on risk roles. It’ll make everything run a lot smoother! (theblock.co).
2. AA using passkeys (P-256). For Layer 2 solutions that have a P‑256 precompile, let’s go ahead and enable passkey sign-ins. And while we’re at it, let’s make sure to only cover gas fees for the transactions that really matter. Let’s dial this back a bit depending on how long someone has been with us and how big their position is. Make sure to keep an eye on how the Customer Acquisition Cost payback stacks up against the expenses from the gas subsidy. It’s important to watch these numbers closely! Let’s keep an eye on how proposals like 7212 and 7951 unfold on the mainnet. It’ll be interesting to see what happens! (eip.info).

7) Restaking-Aligned Dependencies

If you’re relying on external data providers or oracles, it’s smart to go with AVSs that have solid plans for live slashing and multichain verification. This kind of setup can really help keep things secure and reliable! Make sure to keep an eye out for operators who have experience with different AVSs. Hey, just a quick reminder to make sure you add slashing contingencies to your protocol risk documents. It's an important step! If you're curious to learn more, you can find all the details here. It's definitely worth checking out!

Emerging best practices we implement by default

• Gas optimization: Alright, here’s what I’m thinking: let’s move those reentrancy and storage flags over to EIP-1153. It would be smart to switch to packed structs, too. We should pre-calculate those selectors and also cache the msg.sender and length for better efficiency. Plus, let’s make use of MCOPY for managing buffers. And whenever we can, let’s offload the more complex math to off-chain solutions with verifiable commitments to help reduce latency. Sound good? (eips.ethereum.org).
• DA strategy: Let’s take on a “Blob-first” mindset and think of “calldata” as our backup plan. We should definitely set up a multi-DA fallback with SP1-Blobstream. Oh, and don’t forget to check out the fees during those blobless periods to make sure everything stays in line. (docs.celestia.org).
• Uniswap v4 hooks:
• Make sure the hook code stays clean and simple. It’s important to keep the state separate for each pool. Let’s also focus on having solid delta accounting and run some fuzz tests to check on solvency and fee invariants. Let's go with ERC-6909 claim tokens instead of trying to patch together some makeshift IOU system. It just makes more sense! (docs.openzeppelin.com).
• MEV: So, the plan is to keep things private and go for intent execution by default. Let’s run everything through the solver auctions first, and only dip into the public mempool if it’s absolutely necessary. For appchains, let’s go ahead and embrace Rollup-Boost to enable some solid, verifiable, and decentralized block-building. (flashbots.net).
• AA: Let's make sure we’re backing both 4337 and 7702. I think we should stick with module-based wallets, too. It's important to keep those paymaster budgets tight. And whenever we can use passkeys, especially where precompiles are on the table, let's do it! And hey, let's gradually share the gas policies with our users. (blog.ethereum.org).
• ZK: Alright, when picking proof systems, consider the structure of your program and the hardware you're working with. It’s a good idea to lean towards reliable options like the Plonky3 backends and those GPU-boosted primitives. Also, we should think about pipelining the witness generation with Yoimiya to help keep that tail latency nice and low. (polygon.technology).
• Security: Alright, here’s the plan: We’ll kick things off by running some price-oracle and L2 message replay simulations in our CI. After that, let’s dive into some Halmos/Foundry fuzz testing. We also need to make sure we’re doing tests for upgrade safety - super important! Once that’s all set, we’ll aim for some staged rollouts. And just to be on the safe side, we’ll get independent audits lined up with our security audit services. Let’s do this! (7blocklabs.com).

GTM metrics and concrete targets for a 90‑day pilot

What You Can Quantify by Week 12:

By the time you hit week 12, you'll have collected a ton of useful insights and data. So, here’s a quick rundown of what you can expect to measure:

• Keeping Tabs on Your Progress: It's important to know how much you've grown in the important areas. You should have a good sense of your improvements! This could be anything from your workout stats to the milestones you've hit on a project.
• Data Analysis: At this point, you should have plenty of data to begin noticing some trends or patterns emerging. Whether you’re looking at sales numbers or checking out user engagement, you'll definitely be able to uncover some valuable insights.
• Gathering Feedback: You probably have some thoughts and opinions coming in from your team or audience. This will give you a better sense of what's going well and what might need a little adjustment.
• Goal Check-In: Now’s a perfect moment to take a step back and see how you’re doing with your goals. Are you still on target to hit those goals? Or do you think it might be time to tweak your approach a little?
• Resource Allocation: You’ll get a better idea of where your resources are actually heading. This really helps with making any tweaks we need to keep everything running smoothly.

By week 12, you'll really start to feel more confident in the data, and you'll be all set to make some smart decisions for what's ahead!

• Unit-cost reduction You might notice a pretty big reduction in DA spending per transaction--like anywhere from 40% to 90%--when you switch to blob-first batches! In the real world of L2s, we saw fees plummet by anywhere from 55% to an incredible 99% once they started using blobs. Plus, Pectra has cranked up their supply once more! Just a heads up: how much you save really depends on the size of your batch and how you’re using it.
  (galaxy.com). You can actually cut down on router gas costs by around 3-6% using MCOPY and transient locks on those busy paths. It's a pretty neat trick! If you've been hanging onto a lot of heavy guards in the past, you might notice even bigger perks coming your way! (eips.ethereum.org).
• Liquidity ramp speed With Uniswap v4's CCA and automated incentives, getting liquidity for new pools has become way faster and more efficient. We're looking at just a few days instead of dragging it out for weeks! Check out the latest updates over at blog.uniswap.org!
• Execution quality and MEV leakage: Let's talk about how well trades are executed and the whole issue of MEV leakage. You'll see that swap costs are more consistent and slippage is reduced when you use solver auctions and private order flow. Also, when congestion spikes happen, especially on Layer 2s using Flashblocks, you'll notice there are way fewer instances of people wanting to revert or get refunds. It's a positive shift! (theblock.co).
• Activation and retention Account Abstraction (AA) paired with passkeys really makes getting started a breeze! Let's try to boost those first-swap conversions on L2s that support P-256 by about 10-30%. And of course, we need to make sure we're keeping the gas sponsorship costs within our budget. Just a quick reminder to keep an eye on your Customer Acquisition Cost (CAC) payback in relation to what you're spending on sponsorships. It’s super important to stay on top of that! (eip.info).
• Risk profile
• Our external audits revealed that there are absolutely no critical vulnerabilities. On top of that, you’ve got some solid measurable invariant coverage going on. You’re using those foundry/halmos fuzz seeds and keeping an eye on the percentage of hook functions under fuzz, right? Plus, it looks like your replay and oracle simulations are cruising through their gates without any hiccups.

We've gathered some super helpful resources that are perfect for procurement!

Here's a simple KPI sheet that links engineering changes directly to our profit and loss. It covers things like COGS per transaction, sequencer margin, LVR slippage, activation rates, and TVL for every dollar of incentive.

• We've got a bunch of runbooks, some cool diagrams, and proof that we actually ran things on the testnet.

Why the timing is now

Great news! The v4 hooks are now up and running, and they've been thoroughly checked out for large-scale use. Plus, with the new integrations with Ledger and Revolut, we officially have some mainstream options available for everyone! If you let this chance slip by, you might run into some pretty big problems with cash flow and how users interact with your service. Take a look at it here: blog.uniswap.org. You'll find all the latest updates!

Back in May 2025, Ethereum’s blob lane got a nice little boost. Those teams that put in the effort to really fine-tune their batchers back then are now reaping the benefits with more stable and lower data availability costs. Pretty cool, right? It just goes to show that a little extra work can really pay off in the long run! If you want to dive deeper into this topic, check it out here: blog.ethereum.org. It’s got all the details you need!

Hey, guess what? MEV and intents are starting to pop up in the real world of production finance! You’ve probably heard of platforms like Aave and CoW. What's really cool is that preconfirmations are moving from the testnet to the mainnet on big Layer 2s. It's exciting to see these advancements in action! You can jump right in without having to stress about any speculative risks.
If you want to dive deeper into the topic, go ahead and check out this link: theblock.co. You'll find some great details there!

• So, restaking economics are now starting to include slashing and multichain AVS. It's really important to make sure your infrastructure dependencies have well-defined SLOs that are supported by solid economic guarantees. If you're curious to dive deeper into the topic, check it out here: outposts.io. Happy reading!

It's all about getting a solid plan in place to kick off our project! Oh, and we’re also going to send you a super handy one-page KPI target sheet!

• Building and Strengthening (Weeks 3-10): In this phase, we’re going to roll up our sleeves and really get into the nitty-gritty. We’ll focus on optimizing gas and DA, as well as working with v4 hooks. It’s going to be a great opportunity to fine-tune everything! We're also going to bring in solver auctions and make sure those 4337/7702 policies are connected. Plus, we’ll be setting up the ZK pipelines while we’re at it.
• Audit-Ready Ship (Weeks 11-12): During this phase, we’ll whip up a fuzz and property coverage report, run some economic simulations, and make sure all the documents you need for procurement are in order. We'll also set up a third-party audit to make sure everything's running smoothly.

Closing the loop: what success looks like in 90 days

Hey there! Just wanted to let you know that your v4 hooks and router are officially up and running. They now come with ERC-6909, which is great for keeping track of internal accounting, along with some cool solver-protected execution features. Enjoy exploring! Take a look at this: (docs.openzeppelin.com). You'll find some great info there!

• The DA spending is looking pretty solid and steady right now. Blob utilization is right where we want it, with no crazy fluctuations. Plus, the finance team has a handle on COGS per transaction again, which is great to see! Read more at (blog.ethereum.org). Getting new users onboard is now a breeze thanks to smart wallets! We're seeing that passkey groups are doing a much better job of converting into actual users, especially in areas where we provide support. Check out the latest updates over at the Uniswap blog: (blog.uniswap.org). There are some exciting new developments you won't want to miss!
• We've really raised the bar when it comes to security! We've got temporary guards on duty, conducted thorough property checks, and even passed an external audit--so you won’t find any vague “just trust us” moments here! If you want to know more, just head over to 7blocklabs.com.

We're here to meet you wherever you are--whether you're deep into the protocol core, navigating the app layer, or working on the infrastructure. We're all about providing real, measurable returns on investment, not just throwing around big ideas in fancy whitepapers.
