Automated tax engines for institutional wallets really need to break things down and analyze the numbers for each wallet individually now. You've got to figure out those L2 blob fees and get those DAC8/CARF and 1099-DA files exported--all while making sure your month-end close goes off without a hitch! Here’s a practical guide that shows how to link Solidity and ZK implementation with a solid return on investment that’s ready for an audit.

Automated Tax Calculation Engines for Institutional Wallets

Hook: “We can’t reconcile tax lots across 14 chains, and the 1099-DA clock is ticking”

If your team is still trying to wrap their heads around crypto taxes by juggling CSV files and depending on unreliable rules, you might want to rethink your approach. Trust me, you’re already lagging behind.

Hey there! If you're dealing with anything related to the U.S. Hey brokers, it's time to gear up for Form 1099-DA! They'll have to submit that for the 2025 transactions, which is related to gross proceeds, sometime in early 2026. Hey there! Just a heads up--starting in 2026, they’re going to roll out basis reporting bit by bit. So, it’s good to keep a few transitional relief details in your back pocket. If you’re looking for more details, just check this out here. It’s got everything you need!

So, over in the EU, they've got this thing called DAC8 rolling out. Data collection is set to start on January 1, 2026, and they’re aiming to kick off exchanges by September 30, 2027. Exciting times ahead! This new guideline is really shaped by the OECD CARF frameworks and requires gathering TIN and KYC information from people living in the EU. If you're looking for the specifics, take a peek here. You'll find all the details you need!

So, just a heads up: the FATF is planning to give Recommendation 16, also known as the Travel Rule, a refresh in 2025. This update is all about making the rules for sharing originator and beneficiary data uniform across the board. This will help clear up what everyone’s role is in the payment process, which will affect how institutional wallets handle their tasks and check in with counter parties. If you want to dive deeper into it, just check out the link here. Happy reading!

Hey, just a quick reminder about Ethereum's EIP-4844! It’s a pretty cool update that separates fees into two parts: execution gas and blob gas. Definitely something worth keeping in mind! If you're operating an engine, you'll want to take a good look at those blob-specific fields. Be prepared for some ups and downs, especially when you see the BLOBBASEFEE shoot up during busy times! If you want all the details, just check this out here.

  • Finally, we’ve got FASB ASU 2023-08 shaking things up for a bunch of crypto assets. It’s shifting them over to fair value (ASC 350-60), and this will kick in for fiscal years that begin after December 15, 2024. Exciting times ahead! It's important to ensure that your tax subledger matches up with your GAAP financials to keep everything in line with compliance. If you're looking for more details, just check this link out here. It's got all the info you need!

Agitate: The risk surface is bigger than “we’ll clean it up at year-end”

If you overlook the 1099-DA basis reporting in 2027 for trades done in 2026, you're setting yourself up for a world of trouble. We're talking about extra work, potential penalties, and even backup withholding problems. Trust me, you don’t want to go down that road! Navigating "optional methods," figuring out the difference between covered and noncovered assets, and handling those pesky tokenized security wash-sale flags can be quite the challenge. It’s definitely not as simple as just flipping a switch! (irs.gov).

DAC8/CARF exports are so much more than just a bunch of trade lists. They actually need to connect the dots between on-chain transfers and KYC identities, track the flow of assets between wallets, and conform to XML schemas and local formats in over 27 member states. It's a lot more complex than it sounds! (taxation-customs.ec.europa.eu).

When it comes to making Travel Rule interoperability (you know, the IVMS101 mapping) work smoothly between different parties, we’re still dealing with that annoying sunrise problem. Make sure you run pre-trade checks on your counterparties, and it’s a good idea to have some fallback plans ready to go just in case. (notabene.id).

L2 economics have really changed things up; blob gas is definitely not the same as L1 gas! If you don’t get those fee components just right, you might mess up the basis and fees for millions of rollup transactions after Dencun. It's really important to pay attention to the details here! (eip.info).

Hey, just a quick note: when it comes to staking rewards, they’re treated as regular income once you have control and dominion over them. So, keep that in mind! It's really crucial to manage those locks and withdrawals the right way since they have a big impact on creating lots and the capital gains tax (CGT) that follows. (content.govdelivery.com).

So, what’s the outcome? Well, we’re looking at delays in reporting, some tricky audit issues, a longer than usual closing process, and, to top it off, a few regulators who are not exactly thrilled.


Solve: 7Block Labs methodology for institutional tax at scale

We build automated tax engines that aren't just spot-on in terms of accuracy; they're also super user-friendly for procurement teams. At the end of the day, we’re all about four main workstreams. But don’t worry--we make sure there’s a straightforward way to keep everything on track and make sure everyone’s responsible for delivering results.

1) Multi-chain ingestion and classification

  • Protocol-native ETL: We're diving into EVM, including both Layer 1 and Layer 2 solutions, as well as Solana. We're also exploring Bitcoin's UTXO model and keeping up with all the major app chains in the game. This involves taking a closer look at archive-node traces and breaking down events based on the ABI for different token standards like ERC-20, ERC-721, ERC-1155, and ERC-4626. So, when we're diving into L2 fee modeling, we're really digging into some transaction details--like max_fee_per_blob_gas and those blob_versioned_hashes. It’s all about understanding how those bits of info play into the big picture! Also, we're checking out the BLOBBASEFEE (that's opcode 0x4A, by the way) to see how the blob costs stack up against calldata. If you want to dive deeper into the details, you can take a look at this link.
  • Identity resolution: We're putting together a group of enterprise-controlled addresses, like custody, treasury, and program wallets. We're also including those accounts that are tagged as policy accounts and the whitelisted counterparties. So, for the Travel Rule data layer, we're working on mapping IVMS101 for both the originator and beneficiary payloads. We're also making sure to validate fields at the individual level, checking things like name identifiers, TINs, and those essential ISO country codes. Looking to explore more? You should definitely check this out: pkg.go.dev. It’s a great resource!

Where it connects:

2) Wallet-by-wallet cost basis engine (with standing orders)

  • Basis policies: Hey there! Just a heads-up: starting January 1, 2025, we’re going to have to implement some ID methods, along with FIFO, LIFO, and HIFO at the account or wallet level where it makes sense.
    On top of that, we’re going to move away from those “universal wallet” approaches and switch things up with some safer allocation options. If you’d like to dive deeper into this topic, just click here. You'll find some helpful info waiting for you!
  • Standing orders: Hey there! I've got some good news for you about 2025. If your broker stack isn’t totally ready, no worries! Taxpayers will have the option to use book-and-records standing orders. Pretty handy, right? So, starting in 2026, we're going to have to get broker-received standing orders that come with specific identifiers.
    No need to stress! We’ll make sure to keep an eye on everything with our audit trails. You can find all the details right over here. Take a look!
  • Broker alignment: Alright, here’s what we need to do: first off, we’ve got to identify the covered and noncovered flags. After that, let’s explore the de minimis options for stablecoins and NFTs. Lastly, we need to get our heads around the 1099-DA boxes by following the guidelines for 2025/2026. Let’s tackle this step by step! If you want to dive deeper into the details, you can check it out here.
  • Token actions classification:
  • Non-taxable: So, basically, this covers things like wrapping and unwrapping assets, doing internal consolidations, and making deposits or withdrawals between L1 and L2 on the canonical bridge. Just keep in mind that as long as there’s no significant change in the type or amount, it’s all good!
  • Taxable: On the other hand, if you decide to swap, redeem, or dispose of your assets, those actions will be taxable. Just a heads up: tokenized securities are going to stick to the same wash-sale rules for stocks and other securities according to IRS guidelines. So, make sure to highlight this in the system! If you want to dive deeper into this, feel free to check it out here.

Where it connects: While diving into our custom blockchain development services, we took the time to get the broker export logic up and running. Plus, we’re all about bringing your policy UI to life with our awesome web3 development services.

3) Income recognition and fee normalization

  • Staking/validator rewards: You should go ahead and recognize ordinary income based on dominion-and-control. Just remember to mark the fair market value (FMV) as soon as you unlock or receive it. Next, go ahead and create several lots at that fair market value (FMV) for any potential capital gains tax (CGT) down the road. (content.govdelivery.com).
  • L2 Blob Fees vs. Execution Gas: So, here's the deal. L2 blob fees and execution gas are two different things, but they’re both super important in the world of blockchain. Blob fees are those costs you incur when you're using layer 2 solutions, while execution gas is what you use to pay for processing transactions on the network. They each have their own role to play, and understanding how they stack up against each other can really help you navigate the crypto space better. You really need to dig into the details of the fees for each lot. This is especially true when congestion hits, which can really mess with the blob base fee--kind of like those wild “blobscriptions” episodes we’ve seen. (blocknative.com).
  • MEV Rebates and Airdrops: So, let's chat about MEV rebates and airdrops for a second. They're pretty important in the crypto world right now! MEV, or "miner extractable value," refers to the extra profits that miners can snag by reordering transactions. And when it comes to rebates, these are a way to give some of that value back to the users. Airdrops, on the other hand, are like bonus gifts of tokens given out to community members or holders of certain coins. They're a fun way to reward loyal users and keep everyone engaged! So, here's the deal: you’ll want to sort these out according to your policy. Basically, you need to figure out if they fall under miscellaneous income or if they're more like basis adjustments. It might help to jot down some notes to keep track of your thought process and add a few disclosure notes while you’re at it. Just a heads up, this can really depend on where you are--different places have different rules.
  • FX and timestamps: Just a quick reminder: make sure you're using UTC timestamps and keeping track of those exchange rates in a way that you can easily refer back to later if you need to. Hey, have you thought about setting some materiality thresholds? It might help you deal with any of that pesky micro-dust fee rounding. Just a little tip to keep everything in check!

So, here's where everything connects: Boost your accounting controls with our awesome security audit services. We've got you covered! We’re here to help you check out event decoding, get the lot math right, and make sure your FX providers are on point.

4) Regulatory outputs and audit evidence

  • U.S. 1099-DA: So, for 2025, we're only going to see the gross proceeds reported. But come 2026, get ready to include the basis for any of those covered assets. Good news! They've added support for PDAP thresholds and even included some optional methods for stablecoins and NFTs. That's definitely a positive development! Oh, and they’re also going to honor those relief notices. (irs.gov).
  • EU DAC8/CARF: So, we’re gearing up to start collecting data in 2026, and then by 2027, we’ll have some deadlines for exchanging that info. Exciting times ahead! They're getting the KYC/TIN fields and residency requirements sorted out so that everything lines up with the CARF schema and the specific rules for each country. (taxation-customs.ec.europa.eu).
  • FATF/Travel Rule alignment: Hey there! It looks like we're starting to roll out those IVMS101 message builders, along with some due diligence tools for counterparties. Exciting stuff! They're also rolling out the new R. We're looking at 16 data minima along with the chain-of-responsibility, and honestly, that’s a pretty significant step in the right direction! (fatf-gafi.org).
  • GAAP support: So, FASB ASU 2023-08 (that’s ASC 350-60 for you) is shaking things up a bit by bringing in fair value roll-forward. Plus, it connects back to those ASC 820 levels we’ve been talking about. And don't forget, audit-ready subledger exports are now accessible for controllers and external auditors. It definitely makes things smoother for everyone involved! (dart.deloitte.com).

Where it connects: Why not check out our cross-chain solutions development? We can help you put together packages that meet all the necessary regulatory standards. Plus, our dApp development solutions make it easy to integrate everything into your operations without a hitch.


1) ETH L2 Swaps with Blob Fees

Scenario:

Picture a market-maker who’s busy providing liquidity on Base and Optimism, juggling thousands of swaps each day. It's a fast-paced gig, and they’re constantly on their toes!

What We’re Implementing:

We're diving into those type-3 blob-carrying transaction fields, figuring out the BLOBBASEFEE for every block, and then we’re calculating how much each swap really costs in terms of blobs. After that, we’ll convert it to USD so it aligns with our fee capitalization policy. If you wanna dive deeper into it, just click here for more info! We’ll keep an eye on those non-taxable bridge deposits and withdrawals, but when it comes to taxable swaps, we'll handle them like they’re dispositions, meaning we’ll take note of the actual profits and losses. So here’s the deal: in 2025, we’ll be sending out a 1099-DA for the total earnings. Then, when 2026 rolls around, we’ll give you the details on the basis for the covered assets. Also, the DAC8 file will have all the KYC/TIN info along with references for cross-wallet transfers associated with the same beneficial owner. If you want to dive deeper into this topic, you can check out more info here. There’s a lot of useful stuff in that link!

2) Staking Rewards with Lock/Unlock Windows

Scenario:

As a validator, you earn rewards over time, and you’ll have the chance to unlock these goodies after a certain period, which we refer to as T+X.

What We Implement:

We’ll consider it ordinary income when you have full control and ownership of the rewards. Once we get to that point, we'll set up income lots based on the fair market value (FMV) right at that moment. If you sell it after that date, you'll end up paying capital gains tax (CGT). Also, we’ll be keeping some logs to track the evidence for the unlock proofs. If you want to dive deeper into the details, just click here.

3) Tokenized Treasuries and Wash-Sale Flags

Scenario: So, you’re diving into trading tokenized short-term T-bill instruments along with the ETFs that track them.

What we implement:
We definitely have a straightforward difference between how we classify property and security.
When it comes to tokenized securities covered by §1091, we’ll handle wash-sale disallowances and basis adjustments just like the IRS lays it out for those kinds of assets. We’ve got it all covered! If you want all the details, just click here!

4) Broker Standing Orders for 2025 → 2026

Scenario: Your broker stack isn’t able to handle specific-ID right at launch.

What We’re Implementing:

  • 2025: We’re planning to put in place some book-and-records standing orders, kind of like HIFO, following the guidelines from Notice 2025-7.
  • 2026 and beyond: We'll be stepping up our game with broker-received standing orders that use platform-supported identifiers. This way, we can keep everything on file with rock-solid proof that can’t be changed. If you want to dig deeper into it, feel free to visit the IRS website. It's a great resource for more info!

Emerging best practices (Jan 2026 onward)

  • Kick things off by creating “wallet-by-wallet” from the start. Don't forget to use Rev! Proc. Just a heads up: You’ve got until 2024 to sort out that unattached basis before you make your first sale in 2025 or when you’re getting ready to file your tax return for 2025. Make sure you take care of that! (irs.gov). Make sure to handle L2 blob gas separately from execution gas. It’s a good idea to keep snapshots of BLOBBASEFEE so that auditors can easily re-evaluate those historical fees without any confusion. (voltaire.tevm.sh). Hey there! Just a quick reminder to make sure you include the IVMS101 validation. It's super important to have error messages that are easy for users to understand--think about using NationalIdentifierType codes and the ISO-3166 country codes for that. Oh, and don’t forget to incorporate some counterparty VASP reputation scoring too! It'll really help tackle that tricky sunrise asymmetry. Let’s keep it smooth and user-friendly! (pkg.go.dev). Let's dive into the different ways you can earn income from crypto. First up, we've got staking. This is where you lock up your coins to help support the network, and in return, you earn rewards--kind of like earning interest on a savings account, but usually with way better rates!

Next, there's MEV rebates. MEV stands for "Miner Extractable Value," and it’s basically the profit that miners can make from reordering, including, or excluding transactions within a block. If you’re lucky, you might get some of those profits back through rebates, which can be a nice little bonus.

Lastly, we've got liquidity incentives. When you provide liquidity to a trading pair on a decentralized exchange, you often get rewards in the form of tokens or fees. It’s a win-win--you help keep the market flowing smoothly, and you get paid for it!

So, those are some key income classes you might want to explore if you're looking to earn in the crypto space! Hey, just a quick tip: it’s smart to standardize those memo fields to make GL mapping a lot easier later on. And remember to connect them to the fair-value GAAP disclosures under ASC 350-60/820. It’ll save you some headaches down the road! (dart.deloitte.com). Hey there! If you're working within the EU, make sure you gather those DAC8-required details when you're bringing new people on board. It's super important! Alright, so we need to get those CARF/DAC8 extract jobs running in a way that they can handle any chain reorganizations that come our way. We also want to make sure they can handle any reassignments smoothly. Oh, and let’s not forget about setting up a system for country-by-country overrides too. That’ll really help us keep everything organized and efficient! (taxation-customs.ec.europa.eu).


Who this is for (and the exact phrases your teams care about)

  • CFO and Controller - Crypto-focused exchange, neobank, and broker-dealer. So, just a heads up - your training includes data up until October 2023. When gearing up for that, it’s super important to focus on creating an audit-ready subledger. This is your go-to for making sure everything is clean and organized for any audits that come your way!

Also, if you’re diving into financial reporting, don’t forget about the ASC 350-60 fair value roll-forward. This stuff can get a bit complex, but nailing it can really set you apart.

And let’s talk about SOX 404 key controls. Keeping these in check is crucial for compliance and helps you avoid any nasty surprises during audits. It all ties back to material weakness prevention - you definitely want to steer clear of any issues that could pop up here.

Finally, as you think about your processes, remember that close acceleration can really help speed things up. It not only makes your monthly close smoother but also supports those other initiatives we just discussed! ”**.

  • Tax Operations Leader Alright, so when we're talking about tax operations, there are a few key terms you really want to keep in mind: first off, you've got “Form 1099-DA gross proceeds and basis.” Then, there's the distinction between “covered vs. noncovered.” It’s also crucial to think about things on a “wallet-by-wallet basis.” Don't forget about “standing orders (Notice 2025-7),” and let’s not skip “Rev.” Just a heads up, these terms can really help clarify things when you're navigating the tax landscape! Proc. You've got the "2024-28 safe harbor" and "Section 6045(g)" here. Hey, if you want to dive deeper into the details, just hop over to the IRS website. It's got everything you need!
  • Compliance / AML Officer. When you're applying for this role, make sure to emphasize a few important phrases. It's a good idea to mention “DAC8/CARF XML extraction,” “FATF Recommendation 16 (Travel Rule),” “IVMS101 schema mapping,” and don’t forget about “counterparty VASP due diligence.” These terms really stand out and can make a big difference! You might want to check out some useful info over at taxation-customs.ec.europa.eu. It's definitely worth a look!
  • Engineering Lead for the Wallet and Settlement Platform. Hey, just a quick reminder to keep an eye out for these technical terms: “MPC policy engine hooks,” “BLOBBASEFEE opcode (0x4A),” “ABI-driven event decoding,” “idempotent ETL,” and “deterministic fee re-pricing.” They might come in handy! If you’re looking for more info, feel free to check out this link. It’s got some good context for you!
  • Procurement
    Alright, let's break this down. In this part, we definitely want to work in some important phrases like “fixed-bid SOW,” “measurable SLAs,” “RACI,” “TCO reduction,” and “regulatory deadline alignment.” These terms are essential to keep our discussion on point. ”**.

Architecture blueprint (high-level)

  • Data Plane So, we've got these chain indexers that keep an eye on EVM traces, plus they track events, Solana accounts, and even the Bitcoin UTXO map. So, we’ve got this blob fee cache that does a great job of tracking the BLOBBASEFEE for each block along with the base fee. It even includes a bit of replay protection to keep everything secure. Pretty neat, right? Check it out here. So, we’ve got this identity graph that covers a few important things: it incorporates customer KYC, clusters addresses, and even includes IVMS101.
  • Rules Plane
  • This classification helps us figure out the difference between internal moves that aren’t taxed and those that are considered taxable transactions. Hey there! Just a quick heads up about income categories tied to staking, validator rewards (where you have some control), and incentive distributions. If you're curious to dive deeper into this topic, check out the details here. Happy reading! Alright, so here’s the scoop: the basis calculation is done on a wallet-by-wallet basis, using this cool specific-ID engine that keeps track of your standing orders. Just picture it like those 2025 relief measures rolling into 2026 when your broker gets involved. If you want to dive deeper, you can check out more details here.
  • Output Plane Here’s a super useful 1099-DA builder you can use to keep tabs on your proceeds for 2025. It also gives you the scoop on your basis starting in 2026. Whether you’re dealing with non-covered or covered transactions, it’s got you covered. Plus, you have the option for some handy aggregate methods if you want to simplify things even more! You can check out all the details here.
  • We've got DAC8/CARF exports that take care of TIN, residency, and linking across wallets. Learn more here. We've got Travel Rule adapters that are compatible with IVMS101 JSON/protobuf, making it super easy to handle counterparty checks. If you want to dive into the details, just head over here.
  • Control Plane
  • You’ve got logs for re-computation that are pretty straightforward, snapshots of the schema, and some solid change-control processes in place.
  • The reconciliation UI now comes with a handy exceptions queue, lets you override specific IDs, and even gives you the option to consent to repricing.

Take a look at our security audit services to help boost your control plane's security! We've got you covered. We're all about making sure our data is solid and secure. To do that, we prioritize data integrity, set up role-based overrides, and keep clear sign-off traces. It's how we ensure everything stays safe and sound!


GTM metrics that matter

We stay on top of what your board and auditors are likely to want to know.

  • Delivery velocity Alright, so here's the scoop: we're aiming to kick off our first regulated export in about 8 to 10 weeks. This includes things like 1099-DA proceeds or DAC8 capture. After that, we’re looking at an additional 16 to 20 weeks to fully implement everything across various jurisdictions. Honestly, this timeline is pretty typical for over 8 different chains, so we're right on track!
  • Data quality We’re really excited to share that we’ve hit over 99! We've got 95% tax-lot continuity locked in for all the supported chains. Also, once we get past that initial warm-up phase, we notice that it drops to less than 0. So, when it comes to reconciliation, we're looking at about 5% of exceptions for every million transactions.
  • Close acceleration We've really raised the bar lately! We’ve managed to shrink our month-end crypto subledger close time from a slow 10 days down to just 3 days or even less. It’s a huge improvement! And what about auditors? We've created these super handy one-click evidence packs to really simplify things for them.
  • Cost and scale When you look at it on a larger scale, it costs under 20 cents for every 1,000 EVM events that are decoded. We're also using horizontal sharding to manage more than 100 million transactions every month. It's been a game-changer for us!
  • Compliance outcomes Hey there! Just a heads up, we’re on track to achieve complete coverage for standing order evidence--super exciting, especially with the relief coming in 2025! Plus, we’re also getting specific IDs from brokers for 2026 and beyond. We're currently validating the DAC8/CARF extracts using deterministic hashes. If you want to dive deeper into the compliance details, feel free to head over to the IRS website. They’ve got all the info you need!

Heads up: The numbers we're discussing come from the most recent enterprise builds. We’ll get the acceptance criteria sorted out in the Statement of Work (SOW) and kick off the dashboards right from the get-go.


Implementation playbook (condensed)

  • Weeks 0-2: Getting Started and Mapping Out the Plan. Let's get started! First up, we're going to choose our main source of truth.

If you want to learn more, just take a look at this link: eip.info.
  • Weeks 7 to 10: Getting to grips with the basic engine and income rules. Over the next few weeks, we’re going to take a deep dive into things, focusing on each wallet individually. We’ll kick things off by getting a jump on the standing orders for 2025, and then we’ll explore some serious staking control. Plus, we’ll set up some flags for those tokenized-securities wash-sales. It’s going to be an interesting ride! If you want to dig deeper into this, you can check out more details here.
  • Weeks 11 to 14: Getting the regulatory stuff squared away and sorting out reconciliations. During this phase, we’re going to put together a 1099-DA that includes both covered and non-covered sections. We’ll also be digging into the DAC8/CARF data and testing out the Travel Rule messaging. It’s going to be quite the project! For all the details you need, just head over to irs.gov. It’s a great resource!
  • Weeks 15-20: Getting Our Controls in Check, Running Audits, and Preparing for Handover.
  • To finish things off, we’re going to set up an evidence vault to get everything ready for SOX approvals. Plus, we’ll make sure our performance is on point!

Take your project to the next level with our fantastic cross-chain solutions and dApp development. We're here to help whenever you need us!


Why this matters now

  • The U.S. The basis clock starts counting down with transactions in 2026, but just so you know, the EU's clock has actually been ticking away since January 1, 2026. Missing deadlines isn't just a minor slip-up; it can actually cause some major headaches with system reprocessing that definitely draws attention. (irs.gov).
  • Rev. Rul. So, if you’re looking at 2023-14 and ASU 2023-08, you'll see that they've got some tax and financial reporting elements that are pretty much tangled together. If your tax system isn’t able to churn out documentation that’s ready for an audit, you could end up with some pretty chaotic fair-value footnotes and a closing process that’s tough to manage. Trust me, it’s better to stay ahead of the game on this one! (content.govdelivery.com).

Hey there! So, there have been some updates to the Travel Rule and the IVMS101 standardization, and they're really shaking things up. Now, institutional wallets are becoming a big part of the compliance chat, even when it comes to those straightforward transfers. It's kind of interesting to see how these changes are influencing the way we think about compliance in the crypto space! It's really about creating something once and being able to use it everywhere! (fatf-gafi.org).


FAQ-caliber clarifications your team will ask

So, do wash-sale rules apply to crypto? Not really! Crypto is usually seen as property instead of being labeled a "security." "Hey, if you're working with tokenized securities, just a heads-up that wash-sale reporting and adjustments might pop up. Don’t worry, though--our engine's got you covered and will flag these situations for you!" (ttlc.intuit.com).

Hey there! So, you're wondering if L1 to L2 bridge movements are taxable, right? Well, typically, those transfers can be subject to taxes. It really depends on the specifics of the situation, so it's a good idea to check the latest regulations or talk to a tax expert to get the best advice. They can help you figure it all out based on your unique circumstances. Hope that helps! Typically, you won't have to worry about taxes on these transfers unless there's a change in the type or amount involved. We like to think of classic bridges as internal transfers, so we make sure your lots stay intact across chains, all backed up with proof links to keep everything nice and tidy. (help.coinbase.com).

  • Is it cool if we stick with the whole “universal wallet” approach? Not a chance! You’ll have to mix things up a bit. Let's use the 2024-28 safe harbor to determine the unattached basis, and then we'll switch to a wallet-by-wallet approach. Just a heads-up to set up those standing orders for the relief coming in 2025. And don't forget, brokers will start sending out info from 2026 and beyond, so keep an eye out for that! (irs.gov).

So, how do we handle blob fees when things get congested? Make sure to keep an eye on the BLOBBASEFEE for every block. It's a good idea to recalculate the effective blob gas costs together with the base fee to keep everything in check. This way, you won't accidentally downplay costs during those busy times when fees are piling up. (voltaire.tevm.sh).

How We Set Up a Lending Pool for Institutions While Keeping Compliance on Point So, we recently wrapped up a project that we’re pretty excited about--a lending pool specifically designed for institutions, and let me tell you, nailing compliance was a top priority. When we started this journey, we knew that creating a platform that met all the necessary regulations wasn't just important; it was essential. After all, you can have the best idea in the world, but if it doesn’t play by the rules, it’s not going anywhere. We dug deep into research, chatted with industry experts, and took a close look at existing compliance standards. It was a lot of work, but we wanted to make sure we were not only meeting expectations but exceeding them wherever possible. In the end, we crafted a lending pool that not only serves the needs of institutions but also stands the test of regulatory scrutiny. We’re thrilled with what we’ve built and can’t wait to see how it impacts the industry!

**Summary:** So, over the past 12 weeks, we’ve been hard at work creating this really secure, permissioned lending pool using ERC-4626. The best part? Institutions are actually going to be able to use it in the EU and the U.S. by 2026! We’re also adding some cool features, like integrating ERC-3643/ONCHAINID identities to manage who has access. Plus, we're rolling in Chainalysis KYT and TRIS to beef up security even more. It's been an exciting journey!
