With on-chain bond rails, we’ve cut down the time it takes to issue bonds from several days to just a few hours! This means that everyone involved--investors, paying agents, and regulators--can stay in sync and on the same page. It's a real game changer! Let’s dive into how institutional debt desks can make the leap from testing the waters with pilot projects to launching full-scale operations. We're talking about setting things up so you can really see that return on investment, all while having a system in place that's primed for procurement.

Building Onchain Bond Markets: Reducing Friction in Debt Issuance

your current headache

You can definitely nail down a deal in just a few hours, but the real work doesn’t end there. It usually takes around T+3 to T+5 for the operations team to get everything sorted out. They’ve got to finalize the KYC stuff, work out allocations, and manage all those reconciliations between the registrar, CSD, paying agent, and custodians. It's a bit of a juggling act! Coupon schedules are trapped in PDFs instead of being easily coded. It’s frustrating because investor eligibility depends on contracts rather than straightforward code. Plus, DvP is just stuck on its own separate tracks, making everything feel a bit clunky. If any little thing goes wrong in this process, it can really throw a wrench in the works. We might miss out on opportunities, end up with outdated pricing, or deal with annoying issues after the trade.

So, here’s something interesting: the Hong Kong government has just taken a significant step by cutting down the settlement time for tokenized green bonds. Instead of the typical T+5, they’ve brought it down to a much faster T+1. That’s a pretty impressive change! They pulled this off by launching directly on a digital assets platform and making sure to use data standards throughout the entire process. Take a look at this link: hkma.gov.hk. You'll find some interesting information there! So, let’s jump ahead to November 2025. Hong Kong really hit a big milestone by launching the largest digital bond ever, coming in at about HK$10 billion! But that’s not all--they also introduced tokenized central bank money, like e‑HKD and e‑CNY, for primary settlements. This move was a game-changer, helping to significantly cut down on counterparty and funding risks. Pretty impressive, right? If you want to dive deeper into it, check it out here: (hkma.gov.hk).

why delay is now expensive

Hey there! So, there's definitely some buzz happening in the regulatory world. ESMA has thrown out the idea that the EU DLT Pilot Regime should stick around for good and be a bit more adaptable, especially since interest in the market really started to take off in 2025. If we let this chance pass us by, we might miss out on being the first to tap into liquidity and gain some really important insights for our operations. (esma.europa.eu).

Exciting news from the UK's DMO! They're diving into the Digital Securities Sandbox with their DIGIT program and are currently reaching out to vendors. The goal? To create a digitally native gilt. So, if you’re in the game, keep your eyes peeled--procurement cycles are starting up, and things are about to get interesting! (ashurst.com).
Heads up for Basel’s new framework: Mark your calendars because Basel’s cryptoasset disclosure framework is on its way! We’re expecting those updates to officially drop on January 1, 2026.
Your treasury, risk, and audit teams will be keeping an eye out for clear controls related to tokenized cash, settlement, and custody. They’ll want to make sure everything is easy to track and manage. (bis.org).
Liquidity is moving on-chain: As of February 8, 2026, tokenized Treasuries have really taken off, hitting around $10. We're looking at a whopping $1 billion here, with companies like Securitize, BlackRock, Ondo, Franklin, and Superstate all making moves and grabbing their pieces of the market. Basically, your investors already have some cash equivalents on the blockchain, and they’re looking forward to a smooth Delivery versus Payment (DvP) process. (app.rwa.xyz).
**U.S. Making Progress: Fast forward to November 2025, and the U.S. Some institutions pulled off a live digital bond on the Canton Network, teaming up with Broadridge and SG-FORGE to make it happen. So, this floating-rate bond is linked to SOFR, and guess what? DRW snagged it! This really shows that the way regulated bonds are issued in the U.S. is definitely working. market. (broadridge.com).

If you miss this turn, you might find yourself facing pricier capital because of basis risk on those long closures. Plus, you could end up spending extra hours on reconciliations, and your investor base might get a bit all over the place. It's definitely something to keep in mind! So, here's the deal: crypto-native desk cash is starting to rack up some serious yields, and it's also being used as collateral on a bunch of different platforms. For instance, you can find it accepted at places like BUIDL, Binance, Deribit, and Crypto.com. Pretty cool, right? (coindesk.com).

7Block Labs’ methodology for production‑grade onchain bonds

We link up Solidity and ZK implementations with operations that follow all the regulatory guidelines. What we're aiming for is to smooth out the issuance process without having to completely revamp the whole capital structure.

1) Regulatory and Operating Model Mapping

Choose Your Venue and Perimeter: You've got some cool choices to consider! You can go with the EU DLT Pilot (that includes DLT MTF, SS, and TSS), the UK DSS (also known as DIGIT), Hong Kong’s Orion, or even look into ATS/MTF integrations. Take a moment to weigh your options! As we approach July 2026, we’ll make sure our controls align with MiCA timelines. Plus, we won’t forget about the Basel crypto disclosures for banks dealing with on-chain cash. It’s all about keeping everything in sync! If you want to dive deeper into this topic, just head over to ESMA's website for more info!
Deliverables: We want to whip up a control matrix, get the prospectus and term-sheet data model aligned, figure out the custody model (like whether we’re going direct or going with omnibus), and clear up what the registrar function involves.

2) Architecture Decisions -- Public L2 vs Permissioned vs Hybrid

So, here’s the deal with network types: we've seen that permissioned, privacy-focused networks--like HSBC Orion and those using Canton stacks--really play a crucial role in reducing data leaks. They do a great job of keeping everything compliant with KYC rules and settlement needs for financial institutions. It’s pretty impressive how these systems work to protect sensitive info while still getting the job done! On the bright side, public Layer 2s (especially after Dencun) are great for cutting down on transaction costs and making distribution a lot more flexible. We’ve noticed that a hybrid approach tends to be the most effective. It usually begins with primary issuance on either Orion or Canton, and then we manage the secondary discovery process using a whitelisted public L2. If you want to learn more about this, feel free to visit hsbc.com. There’s a lot of great info there!

We specialize in cross-domain orchestration by utilizing enterprise bridges and approved ERCs. If you’re curious to dig deeper, why not check out our cross-chain solutions development and blockchain bridge development? There’s a lot of exciting stuff happening there!

3) Smart Contract Design Patterns for Bonds

So, we're diving into ERC-3475, and it's really interesting because it focuses on multi-class bond obligations. It includes all sorts of stuff, like series, tranches, and nonce structures, plus the lifecycle metadata as well. Next up is ERC-3525. This one's pretty cool because it deals with semi-fungible positions. Basically, it lets you split and merge face values, along with making partial transfers. It's all about adding some flexibility to how we handle assets! Finally, there's ERC-3643 (T-REX), which brings in a few rules about identity-bound transfers. If you want to get into the nitty-gritty details, you can check it out here.

The key fields match up really well with the ICMA BDT. Forget about those PDFs! Now, coupon and call schedules are going to be something you can actually execute as events. We're working on mapping ISIN and LEI and connecting them to DTI (ISO 24165:2025) to create a strong digital token identity. If you want to learn more about it, you can check it out here.

If you're curious about it, we provide smart contract development and custom blockchain development services. Just let us know if you want to know more!

4) Investor Eligibility, KYC, and Privacy

We rely on on-chain allowlists that are powered by ERC-3643 to help us stick to geographic and qualification guidelines, such as 144A and Reg S for professional investors.
Thanks to zero-knowledge (ZK) credentials, we can easily verify if someone has passed KYC or if they're not on any sanctions list. And the best part? We can do all of this without sharing any personal info during those secondary transfers on public Layer 2. How cool is that? This really helps us reduce the risks that come with handling data. If you want to dive deeper into this topic, check it out here. It's definitely worth a look!

We're super focused on bringing together providers for verifiable credentials and sanctions screening, but we make sure to keep any sensitive data off-chain. Take a look at what we offer! We've got some great services for security audits and web3 development.

Cash leg -- think of it as an atomic DvP that you can actually keep an eye on. You've got a few different paths you can take here. First off, you might want to check out tokenized central bank money, if that's an option in your area. Then there are tokenized deposits to consider, as well as regulated tokenized funds or stable assets. It really depends on what fits your needs best! Check out Hong Kong’s 2025 issuance! It really highlights how the e-HKD and e-CNY can team up when it comes to primary settlement. On top of that, there are tokenized money-market funds like BlackRock's BUIDL, which have skyrocketed to multi-billion dollar assets under management. And guess what? They're now being accepted as off-exchange collateral. This just goes to show that your counterparties are totally on board with funding on-chain. (hkma.gov.hk). We're excited to announce that we're launching DvP adapters for permissioned networks and workflows that are triggered by ISO 20022! It's pretty similar to what we've seen with the Swift/UBS/Chainlink pilots in Project Guardian. How cool is that? You’ve got to check it out! (coindesk.com).

Take a look at what we offer: blockchain integration.

6) Data Standards and Interoperability

The ICMA BDT is our favorite schema to use. We create easy-to-read term sheets, stay on top of important lifecycle events, and share information about green initiatives. We've got our DTIs connected to ISIN/LEI, and we send out ISO 20022 messages for primary markets and asset servicing. This makes everything run smoothly and efficiently! Take a look at this link: icmagroup.org. It’s pretty interesting!

7) Security, Auditability, and Ops

Formal properties: things like transfer restrictions, coupon accrual limits, the time frame for redemptions, and how call logic works.
We’ve got everything covered when it comes to key management, registrar functions, and making sure business continuity is in place for regulated environments.
Before we launch, we make sure to do some third-party audits and put our systems through adversarial testing. Hey there! If you want to dive deeper into what we offer, take a look at our security audit services. You're going to find all the details you need!

8) Pilot to Production GTM

Let's start by diving into a single series, like a commercial paper or maybe a sustainability-linked tranche. Once we wrap up T+1 with tokenized cash, we’ll open up secondary liquidity by using approved venues. From there, we can really get things moving with our multi-currency programs. We're all about getting distribution in sync with the investor operations that are already happening on-chain. Consider institutions that are diving into the world of tokenized Treasuries, which is quite a sizable market at $10 billion. They're also exploring money-market tokens as collateral. Take a look at this: app.rwa.xyz. You might find it interesting! We're juggling a few legal tasks at the same time to ensure that all the disclosures, selling restrictions, and accounting stuff are good to go for full production. It's a bit of a balancing act, but we're on it!
Looking for some assistance? We’re here for you! Check out our services for asset tokenization and dApp development. We’ve got you covered!

1) Sovereign/Municipal “Digital Green” Program

Platform: We're excited to start this journey using HSBC Orion as our main platform! On top of that, we've got CMU/CSD connectivity, and you can also choose hybrid distribution through a specially curated public L2.
Standards: We're incorporating the ICMA BDT into our framework and connecting DTI (ISO 24165:2025) with ISIN/LEI. You can look forward to finding machine-readable green disclosures right on the blockchain. Check it out here.
Settlement: We're targeting T+1 settlements and looking to use tokenized central bank money whenever possible--kind of like what they’re doing in the HK e-HKD/e-CNY pilot. It’s pretty exciting stuff! If that's not the case, we’ll just go with tokenized deposits instead. More info here.
Outcome to Target: Our goal here is to streamline the allocation-to-close process so that we can get it down to under 24 hours. We also want to make sure disclosures and lifecycle events are consistent, which will really help simplify our reporting cycles.
Build Scope: This part's all about integrating blockchain technology and developing smart contracts. You can check out what we offer here for blockchain integration and here for smart contract development.

2) Corporate Commercial Paper (CP) on EVM L2 with Bank Rails

Instruments: So, we’re tapping into ERC-3475 for our multi-tranche CP, and for showcasing investor positions that can be partially transferred back to the dealer when rolling, we're using ERC-3525. Take a look at this link: (eips.ethereum.org).
Eligibility: So, with ERC‑3643, we've set up an allowlist that leverages ZK credentials to confirm your status as a "professional investor." The registrar holds onto KYC info, so you won't find that stuff being shared on the blockchain. If you want to dive deeper into the details, just check out this link: erc3643.org. You'll find everything you need there!
DvP: We’re checking out some tokenized deposits from our partner bank. Also, the treasury workstation is going to start sending out ISO 20022 messages, which will trigger the on-chain minting and settling through orchestration. Exciting times ahead!
What We're Shooting For: Our goal is to make CP transactions super smooth, allow for real-time reissues when the market gets shaky, and keep everything tidy for SOX compliance and internal audits.
Build Scope: We’re excited to explore some cool cross-chain solutions and provide awesome web3 development services too!

3) Asset-Manager Liquidity Sleeve (Cash Management for Treasurers)

Market Reality: Tokenized cash and Treasury funds are seriously gaining traction on-chain! Take BlackRock’s BUIDL, for example--it skyrocketed past $1 billion in assets under management back in March 2025 and continued to broaden its utility as the year went on. It’s pretty impressive to see how quickly things are evolving! If you're interested in learning more about this, check it out here. It's packed with details!
Workflow: We're all about simplifying things for investors. That's why we're working on a way for them to easily subscribe or redeem using ISO 20022 through the standard Swift channels. Fund operations on-chain are going to roll out using Chainlink’s runtime and Digital Transfer Agent patterns. This approach has already gone through some serious testing and validation in the UBS/Swift pilots as part of Project Guardian. Pretty cool stuff, right? If you're curious and want to dive deeper into the details, feel free to take a look here. It’s definitely worth checking out!
What We're Aiming For: The main thing we want to achieve is to smoothly connect our fund operations with the cash side of bond settlements. This will enable real atomic delivery versus payment (DvP) for primary allocations.
Build Scope: We're diving into developing an asset management platform and integrating blockchain technology. This is how we’re planning to bring everything to life!

Best emerging practices we deploy

Think of the "term sheet as code." So, kick things off by creating the bond in the ICMA BDT. With that source you have, you can easily create the ERC‑3475/3525 class/nonce map along with the Swift/ISO 20022 messages. It helps keep everything organized! You can check it out here.

It’s time to get on board with DTI! Just make sure your digital token identifiers are in sync with ISIN and LEI. Taking this small step now will really simplify things for CSD and make the onboarding process for custodians a whole lot smoother in the future. (iso.org). When you're choosing cash leg options for a venue, aim for options that really fit the vibe. If you're working with permissioned platforms, consider going with e-money or tokenized deposits - they can work wonders! If you're a public L2 pilot, I'd suggest looking into regulated tokenized money market funds or fiat-backed stablecoins. And hey, don’t forget to keep those Basel disclosures in mind when chatting with your banking friends! (bis.org).
Make use of allowlists right at the contract level: thanks to ERC-3643, you can set up eligibility from the get-go. This way, you won't need to rely on off-chain systems to check everything for each transfer. And don’t forget to add in ZK attestations to keep your personal info private! (erc3643.org). Alright, so here's the game plan: let's focus on a hybrid distribution strategy. We'll prioritize Orion and Canton for our main channels, and then we can allow secondary discovery to unfold through a public Layer 2 that’s whitelisted. It’ll give us the best of both worlds! This means you can dive into DeFi-native collateral accounts, where institutions are already keeping their tokenized cash. (hsbc.com).
Keep tabs on the ongoing policy trends: make sure you’re updated on what ESMA's doing to enhance the DLT Pilot, check out how ICMA is taking the lead in the Project Guardian fixed-income workstream (where they're zeroing in on DvP and custody), and don’t forget about the UK DIGIT program! These steps are going to help clear up any regulatory confusion for your plans in 2026. (esma.europa.eu).

Prove -- GTM and operational metrics that matter

We set up goals that are grounded in real-world benchmarks to help your CFO and procurement team back the changes you’re looking to implement.

Cycle time: We're shooting for a T+1 close on our primary issuances, just like those T+1 sovereign digital bonds in Hong Kong. So, our big stretch goal is to aim for T+0 for the smaller tranches, but only if we've got the cash already set aside.
(hkma.gov.hk).
Liquidity alignment: We're going to make sure our distribution list includes investors who already have tokenized Treasuries, which are currently valued at around $10. As of February 8, 2026, there’s a whopping 1 billion still out there. This approach helps us reduce any risks associated with getting started. (app.rwa.xyz).
Collateral utility: We’re looking to demonstrate that the proceeds can comfortably hang out in tokenized Money Market Funds or solid stable coins that act as collateral on major platforms like BUIDL at Binance, Deribit, and Crypto.com. This helps keep the returns coming in smoothly between deals. (coindesk.com).
Interoperability: We're diving into subscriptions, redemptions, and DvP events that are triggered by Swift/ISO 20022. We're currently testing these out through some pilot programs with UBS and Chainlink. We'll keep tabs on this using the STP rate and the number of exceptions to ensure everything runs smoothly. (coindesk.com).
Regulatory stance: We really need to get a clear picture of our disclosures and key regulatory checkpoints, especially with Basel's 2026 deadlines and the guidelines from the EU and UK sandbox.
We'll also make sure to document the DLT stack and the custody arrangements that come along with it. (bis.org).

What we deliver, concretely

Architecture and delivery:
Let’s jump into smart contracts! We’re talking about stuff like ERC-3475 and 3525, along with some permissions from ERC-3643. We'll also cover coupon and redemption engines, registrar modules, and event logs--all designed to align with ICMA BDT standards. Exciting, right? We've got DvP adapters all set for when tokenized deposits and central bank digital money come on the scene. And on top of that, we've rolled out ISO 20022 connectors for our operations that are powered through Swift. Exciting times ahead! We're also creating cross-domain bridges that include compliance checks for secondary distribution.

Why now?

ESMA's got some exciting plans lined up for 2025! It seems like they’re gearing up to expand and could even turn the DLT Pilot into a permanent thing. No more playing the waiting game! In the meantime, ICMA is really stepping up to the plate with Project Guardian, pushing forward on DvP and custody standards. And over in the UK, DIGIT is on the lookout for some cool tech to help launch a digitally native gilt. Exciting times ahead! (esma.europa.eu). Wow, the market depth is really making waves! Tokenized Treasuries have actually crossed the $10 billion mark! It's pretty exciting to see how BUIDL is growing and proving its worth as collateral. It looks like institutional money is definitely finding its way on-chain and doing its thing like a champ! (app.rwa.xyz).

We've got some really interesting stuff happening in the U.S. So, there are some cool examples of digital bonds coming from Broadridge and SG-FORGE on the Canton platform. Plus, Hong Kong is really making strides by demonstrating some solid evidence at a sovereign level. They’re diving into e-money with Delivery versus Payment (DvP) and even hitting that T+1 settlement timeline. It's pretty impressive! (broadridge.com).

Here are the main specs we'll be launching right from the start.

Executable term sheets: So, the ICMA BDT connects with ERC‑3475 and ERC‑3525 objects. Plus, there's the DTI (ISO 24165) linked up with ISIN and LEI. (icmagroup.org).
Transfers with a twist: Thanks to ERC-3643, you not only get allowlists but also ZK credentials. This means your personal info stays off the blockchain, keeping things private and secure. (erc3643.org).
Atomic DvP works by utilizing tokenized deposits or, when it's possible, central bank money. Events are managed with ISO 20022/Swift technology. (hkma.gov.hk).
Hybrid venues: You might want to take a look at Orion/Canton for the main markets. They've got some cool public L2 liquidity options that make it easier to discover what you're looking for. (hsbc.com).

Hey there! If you're leading the charge as the Head of DCM or Corporate Treasurer and are thinking about issuing in Q3-Q4 of 2026, we’ve got something exciting lined up for you! We’re ready to dive into a 2-week “Bond Tokenization Readiness” sprint. We’ll team up with your syndicate desk, legal crew, treasury operations, and InfoSec experts to get everything prepped and ready to go. Let’s make it happen! So, what’s the aim here? We’re looking to focus on a T+1 pilot that wraps up as we move into your next round of funding. We're going to be working with ICMA BDT-native term sheets, along with some cool ERC-3475 and ERC-3525 instruments. Plus, we’ll be looking at ERC-3643 for eligibility and using ISO 20022 for our delivery versus payment (DvP) setup.

So, here’s the deal. If we can’t demonstrate some real improvements in cycle time and provide a clear audit trail within the next 30 days, it might be a good idea to reconsider moving ahead. But if we can make that happen, you'll be ready to take things to the next level! Alright, let's kick things off by focusing on our awesome asset tokenization services. We want to make sure we're clear on what we’re delivering, especially when it comes to smart contract development, blockchain integration, and our security audit services. Sound good?
