The Onchain Analyst Risk and Ledger Compliance Wire Data Block Weekly The Surveillance Brief

Blockchain Stars is a blockchain development company based in Douglas, Isle of Man, that delivers enterprise blockchain development: real-time on-chain analytics, AML screening and transaction monitoring at petabyte scale for compliance teams, exchanges and risk desks worldwide. Founded in 2020, it has indexed 1.4 trillion on-chain events across nine chains with zero critical findings across 78 production contracts, making it a trusted blockchain technology partner for regulated FinTech, custody and exchange teams.

The platform

On-chain intelligence, answered in milliseconds

Real-time indexing, risk scoring and surveillance across nine chains, built on a petabyte-scale analytics engine.

On-Chain Analytics

Blockchain data indexing at petabyte scale: event indexing across nine chains with p99 query latency under 90 milliseconds. The foundation of every compliance and risk signal we produce.

AML and Monitoring

Real-time transaction monitoring with configurable DeFi risk controls: alerts in seconds, far fewer false positives and case-management exports ready for regulators.

Risk Scoring

Address and transaction risk scores updated continuously as new on-chain data arrives. Incorporates oracle risk management signals and cross-chain exposure analysis.

Sanctions Screening

Screen counterparties against sanctions and watchlists across every chain you touch, with cross-chain integration ensuring no hop goes undetected.

Market Surveillance

Detect wash trading, spoofing and manipulation patterns that single-chain tools miss. Built on scalable blockchain development practices for reliable, low-latency signal delivery.

Data API and Feeds

Web3 data pipelines that stream typed on-chain data and risk signals straight into your own systems via our on-chain data APIs.

Smart Contracts and dApps

Audit-ready smart contracts: monitoring, oracle and tokenization contracts built with smart contract security best practices and smart contract threat modeling baked into every engagement. Production-ready from day one.

Audits and Assurance

Independent audits before launch covering smart contract audit readiness, Foundry testing and fuzz coverage. Then ongoing monitoring and managed assurance so nothing slips after deployment.

Cross-Chain Tracing

Follow value as it hops between chains, the gap where most laundering escapes. Our cross-chain integration spans all nine indexed networks with bridge risk management signals inline.

How it works

From raw chains to answers in four steps

Every alert, risk score and report begins with raw blockchain data arriving in real time, processed through four deterministic stages before a compliance team ever sees a flag. This is what blockchain infrastructure development at petabyte scale actually looks like in production.

1

Index

We ingest nine chains in real time into a petabyte-scale analytics engine built on reliable blockchain architecture, events landing within seconds of on-chain confirmation.

2

Model

Risk models, heuristics and labels turn raw transactions into scores, flags and entity graphs. Permission design and key management decisions are part of the smart contract architecture from the start.

3

Alert

Tuned rules fire alerts in seconds, with the false-positive noise stripped out so analysts trust them. Upgradeability planning means the rule engine adapts as new laundering patterns emerge.

4

Report

Cases, audit trails and suspicious-activity reports export in minutes, ready for regulators. The output of secure blockchain development applied to compliance at scale.

Why us

A real-time engine vs a block explorer and a spreadsheet

Most crypto compliance teams start with public block explorers and manual lookups. The table below shows exactly where that approach breaks down at scale.

Factor Built with Blockchain Stars Explorer plus spreadsheet
Speed Alerts in seconds, queries in under 90 milliseconds Hours of manual lookups, one address at a time
Scale 4.2 petabytes across nine chains, indexed in real time Whatever fits in a browser tab
Cross-chain Trace value as it hops between chains automatically Blind the moment funds leave one chain
False positives Tuned models that analysts actually trust Alert fatigue until people stop looking
Audit and reporting Suspicious-activity reports and exports in minutes Days of copy and paste before an audit
Security Independently audited, fuzzed and formally verified A macro nobody has reviewed
Cost Free to USD 180,000 per year by tier Cheap until the first missed sanction or fine

Best fit for the engine: compliance teams, exchanges and risk desks with real obligations. Best fit for an explorer: a one-off lookup with nothing on the line.

Chain selection guide

Which chain to build your compliance system on

Chain choice determines your data volume, finality guarantee and compliance fit before a single line of code is written. Use this matrix when scoping a new monitoring or analytics engagement as a Blockchain Development Company client.

Chain Best for Finality Compliance fit Cost per query
Ethereum DeFi risk, tokenization, ERC-20 AML ~12 s (single slot) Excellent: deep entity attribution, OFAC SDN exposure Medium (high state complexity)
Bitcoin Cross-chain laundering tracing, mixer detection ~60 min (6 confirmations) Critical: highest illicit-volume share, UTXO clustering Low (UTXO model, simpler state)
Tron Stablecoin AML (USDT-TRC20), OTC desk screening ~3 s (delegated PoS) High: #1 chain by illicit stablecoin transfers globally Low (high throughput, low fees)
BNB Chain Retail DeFi monitoring, bridge-risk tracking ~3 s Good: EVM-compatible, large bridge volume Low to medium
Solana High-frequency trading surveillance, NFT fraud ~0.4 s (probabilistic) Emerging: fast-growing SPL token volume Medium (high event rate)
Polygon PoS Bridged-asset tracing, gaming and payments compliance ~2 s Good: EVM parity with bridge exposure signals Low
Arbitrum / Base L2 DeFi, exchange withdrawal monitoring ~1 s onchain + L1 finality Growing: exchange and custody L2 deposits Low (rollup compression)

Every chain above is indexed in real time. The Blockchain Development Company engagement starts with a chain-priority assessment: we help you allocate monitoring budget to the chains where your actual risk exposure lives.

Honest scope

When blockchain analytics is not the answer

Blockchain Stars declines roughly 38 percent of enquiries. Knowing when to say no is as important as knowing what to build.

  • Questions a free public block explorer already answers in one click
  • Teams with no compliance, risk or surveillance obligation to meet
  • Token launches without legal counsel on securities classification
  • Vanity dashboards that look impressive but drive no real decision
  • Anything where off-chain data alone would answer the question faster
We decline roughly 38 percent of enquiries. If a free explorer answers your question, we will point you to it and move on.

The stakes are real. According to the Chainalysis 2024 Crypto Crime Report, USD 1.7 billion was stolen from DeFi protocols in 2023, and a recurring pattern in laundering is value hopping across chains within minutes, which single-chain monitoring never sees.

Pricing transparency

What determines the cost of your engagement

Every Blockchain Stars proposal is scoped against six cost drivers. Understanding them before your first call saves a round of back-and-forth and ensures we quote the right tier from day one.

01

Chain coverage

Each additional chain requires a dedicated indexing pipeline and model tuning. A single-chain deployment is materially cheaper than nine-chain cross-chain tracing, which is our most common enterprise scope.

02

Data volume

Petabyte-scale indexing costs more than a small-exchange deployment. Teams with under 500,000 daily transactions often find the Team tier sufficient; teams above one million transactions per day typically require Compliance or Enterprise.

03

Audit depth

External security audits, formal verification (Halmos) and penetration testing are priced separately from the build. Independent audits add USD 15,000 to 45,000 per engagement depending on contract complexity and line count.

04

Compliance integrations

Connecting to your SIEM, existing case-management system, sanctions watchlist provider or KYC API adds integration complexity. Standard connectors (Splunk, SAR exports) are included in Enterprise; custom connectors are scoped separately.

05

Timeline

Accelerated delivery (under six weeks for a bespoke build) requires a larger concurrent team and carries a premium of roughly 20 to 30 percent over standard pace. Regulatory deadlines often dictate this choice.

06

Regulatory framework

Building for MiCA, FATF Travel Rule, FinCEN or a multi-jurisdiction compliance programme requires additional legal-alignment work and documentation beyond standard AML monitoring, and is priced as a compliance layer add-on.

The fastest way to get an accurate quote is to tell us: your chains, your daily transaction volume, your regulatory deadline and your existing tooling. We turn that into a precise number within 48 hours.

How we engage

Three ways to work with Blockchain Stars

Every engagement starts with a scoping call to match the model to your compliance timeline and team structure.

What you receive

Concrete outputs from every build engagement

A Blockchain Stars bespoke build does not end with deployed code. Every fixed-scope engagement delivers a documented, audited, transfer-ready package so your team can operate, maintain and extend the system independently.

Audited and source-verified contracts

All on-chain contracts independently audited before deployment, Foundry-fuzzed with formal verification where applicable. Audit report and source-verification links delivered as part of handover.

Deployment runbook

Step-by-step deployment instructions covering key management, upgrade procedures, node dependencies and rollback plan, written for your internal engineering team.

Threat model and risk register

A documented threat model covering smart contract security, oracle risk, bridge exposure and key management vectors, plus a risk register you can present to your compliance and security teams.

Data API and integration SDK

A fully documented REST and WebSocket API for on-chain data access, plus a lightweight integration SDK covering the most common query patterns, ready for your analysts and system integrators.

Full technical documentation

Architecture diagrams, data model documentation, alert-rule configuration guide and a query cookbook covering the top 20 compliance queries your analysts will run in the first 90 days.

Knowledge transfer and handover

Two structured handover sessions with your team covering architecture decisions, model tuning and ongoing maintenance cadence. You own the IP and source from day one: no lock-in, no ongoing licence for the code we wrote for you.

Risk reversal

How we protect your project and your team

Every Blockchain Stars engagement is structured to eliminate the common failure modes of compliance builds: scope drift, opaque IP, late audits and vendor lock-in.

Free scoping call

Every new enquiry gets a no-charge, 45-minute scoping session with a senior engineer. We map your chains, data volume and compliance obligation to the right tier or build scope before any proposal is issued.

Fixed-price discovery

We offer a capped-fee, two-week discovery phase (USD 8,000) that produces a complete technical specification, effort estimate and risk register. You can take that document to any firm. Most clients proceed with us, but the choice is yours.

Client owns IP and source

All code, models, documentation and data schemas produced in a bespoke build are assigned to you in full under the Statement of Work. There is no ongoing code licence: the system is yours to operate, fork and extend.

Audit-pass commitment

Every smart contract we deploy goes through an independent audit. If the audit identifies critical or high-severity findings in code we wrote, we fix them at no additional cost before mainnet deployment. Zero critical findings in 78 production contracts to date.

No vendor lock-in

The platform uses open standards throughout: documented APIs, portable data formats and no proprietary runtime dependencies. You can migrate the data layer, swap node providers or bring the system in-house without renegotiating with us.

Defined exit and handover

Every enterprise contract includes a documented exit plan: a transition runbook, a 90-day handover period, data-export tooling and a named point of contact at Blockchain Stars for post-handover questions at no additional charge.

First two weeks

Platform subscribers are live within one week: credentials, chain access and the first monitoring rules are configured in the initial onboarding call. Bespoke builds begin with a kickoff and architecture review in week one, a working proof-of-concept indexer by end of week two, and a full draft specification signed off before any production code is committed.

The team

About the founder

Blockchain Stars is led by Daniel Kent, a data engineer who built real-time data infrastructure at exchange and payments scale before founding the company in 2020 to bring petabyte-level on-chain analytics to compliance teams.

Daniel Kent

Founder and CEO

  • MSc Data Science, University of Edinburgh (2013)
  • Former data engineer at a market-data and exchange firm
  • Built a real-time transaction-monitoring system at a payments company (blockchain backend development at exchange scale)
  • Focused on petabyte-scale analytics, AML and real-time risk scoring; provides ongoing blockchain consulting and smart contract consulting to regulated clients

I am a data engineer by trade. I spent years building systems that had to answer hard questions over enormous datasets in milliseconds, and I kept watching crypto compliance teams try to do the same job with a block explorer and a spreadsheet. Our team of 44 now indexes 1.4 trillion events and scores 320 million addresses, every monitoring contract independently audited with nothing lost.

Blockchain Stars started in 2020 after I watched a laundering case go cold because the funds hopped across three chains in under ten minutes and nobody had a tool that could follow them in time. The data existed. The speed did not. We built an engine where real-time means seconds, not a next-day report, and "if the alert is late it is useless" has been our rule since.

Blockchain Stars Research

Reading the chain in real time

Research Note BST-2026-07 analyses 61 million flagged transactions from 2020 to 2025 and shows that 64 percent of evasive laundering flows beat single-chain monitoring by hopping between chains within minutes.

Research Note BST-2026-07 33 pages, May 2026 Daniel Kent and the Blockchain Stars team

Abstract

This note examines why on-chain laundering evades detection. We analyse 61 million flagged transactions between 2020 and 2025, separating each into a single-chain signal and a cross-chain signal. Across the dataset, 64 percent of laundering flows that evaded detection did so by hopping across chains within minutes, beating any single-chain monitoring tool. We present a real-time, cross-chain analytics architecture grounded in scalable blockchain development principles and quantify its detection effect across two production deployments. The architecture reflects a security first blockchain development approach: every component is independently fuzz-tested and the smart contract CI/CD pipeline enforces contract test coverage gates before any update reaches mainnet.

Key findings

  • 64% of evasive laundering flows hopped across chains within minutes, beating single-chain tools
  • Cross-chain, real-time tracing recovered detections that post-hoc analysis missed entirely
  • Sub-90-millisecond query latency made interactive investigation across petabytes practical
  • Zero funds lost across all 78 production contracts in the studied period

AI meets on-chain

How AI is reshaping blockchain analytics and compliance in 2026

AI does not replace on-chain analytics. It amplifies it. Blockchain Stars integrates machine-learning techniques into the core analytics engine to surface patterns that rule-based systems miss, reduce false positives and accelerate investigation workflows.

ML risk scoring

Gradient-boosted models trained on 1.4 trillion labelled on-chain events score address risk in real time. The model generalises to new laundering patterns without manual rule updates, cutting false-positive rates by a further 30 to 50 percent compared to rule-only baselines.

Graph neural networks for clustering

Entity clustering and address attribution now use graph neural networks applied to transaction topology, substantially increasing the accuracy of "common input ownership" inference on UTXO chains like Bitcoin and entity linkage on EVM chains.

LLM-assisted investigation

Compliance analysts can now pose natural-language questions to the on-chain data ("show me all wallets that touched a Tornado Cash successor within 48 hours of receiving funds from exchange X") and get structured query results without writing SQL, reducing investigation setup time from hours to minutes.

Autonomous on-chain agents (emerging)

DeFi protocols are beginning to deploy AI agents that initiate and settle transactions on-chain autonomously. These agents need the same AML and risk screening infrastructure that human-initiated transactions do, and they are faster. Blockchain Stars is building the monitoring primitives that keep regulated exchanges safe when their counterparties start to include AI agents.

Anomaly detection at scale

Unsupervised anomaly detection flags transaction patterns that fall outside the historical behaviour of an entity without requiring a pre-labelled ground truth. This is particularly valuable for detecting novel wash-trading strategies on DEXs and for cross-chain bridge exploits in their early seconds, before a pattern name exists for them.

AI-augmented SAR drafting

When an alert is escalated to a case, AI-assisted SAR drafting pre-populates the narrative with entity information, flow timeline and supporting evidence from the analytics platform. Analysts review and submit rather than write from scratch, cutting average SAR preparation time from eight minutes to under three.

How to evaluate us

Questions to ask any blockchain development company before you hire

Choosing a Blockchain Development Company for compliance-critical work is a high-stakes decision. These six criteria are what separates a firm that will pass your next regulatory audit from one that will not.

Do they have production deployments on your specific chains?

Ask for mainnet contract addresses and the chains they are deployed on. A firm with 78 production contracts across nine chains has a fundamentally different risk profile from one with only testnet deployments. Blockchain Stars publishes its audit reports and production contract counts on this page.

What is their independent audit record?

External audits by a named third party are the minimum bar. Ask for the actual report, not just the firm's claim of being "audited". Blockchain Stars holds a 100 percent first-pass rate: every contract passed independent review before deployment, with zero critical findings in 78 production contracts.

How do they handle cross-chain compliance?

Most laundering hops chains within minutes, which single-chain tools miss by design. Ask whether the firm's monitoring engine traces value across chains in real time or only after the fact. Our Research Note BST-2026-07 quantifies the gap: 64 percent of evasive laundering flows beat single-chain monitoring by hopping chains.

Do they hold the certifications your regulators require?

ISO/IEC 27001, SOC 2 Type II and jurisdiction-specific designations are what most regulators ask for in a third-party supplier. Check certificate numbers and issuing bodies, not just logos on a website. Blockchain Stars' certificates are listed with full details in the Certifications section above.

Will they tell you when you do not need them?

A firm that declines work it is not suited for is a firm you can trust with the work it accepts. Blockchain Stars turns down roughly 38 percent of enquiries, pointing teams to a free block explorer when that is the honest answer. That discipline protects the quality of what we say yes to.

Who owns the IP and what happens when the contract ends?

Insist on full IP assignment to you in the Statement of Work, a documented exit plan, a handover period and data-export tooling. Blockchain Stars builds all of this into every enterprise agreement by default: no lock-in, no ongoing code licence, defined exit and handover at no extra charge.

Indexing and analysing public blockchain data to answer questions about flows, risk and behaviour, usually at large scale and in real time.
AML
Anti-money laundering. The controls and monitoring a regulated business uses to detect and report attempts to launder funds.
Transaction monitoring
Watching transactions as they happen and flagging the ones that look suspicious, so a compliance team can review and report them.
Risk score
A continuously updated measure of how risky an address or transaction is, based on its history, counterparties and on-chain behaviour.
Sanctions screening
Checking a counterparty against official sanctions and watchlists before or as a transaction occurs.
SAR
Suspicious-activity report. The formal report a regulated business files when it detects activity that may indicate financial crime.
Cross-chain tracing
Following value as it moves between different blockchains, the gap where most sophisticated laundering tries to escape detection.
p99 latency
The query response time that 99 percent of requests come in under. We treat p99, not the average, as the target because the slow tail is what stalls an investigation.
Petabyte
A thousand terabytes. The scale of on-chain data we keep indexed and queryable in real time.
Smart contract security
The discipline of designing and testing on-chain code so that no exploitable path exists at deployment. Covers smart contract threat modeling, permission design, upgradeability planning, key management, oracle risk management and bridge risk management as separate concerns to evaluate at architecture stage.
Blockchain infrastructure
The indexing, storage, query and alerting layers that sit beneath compliance dashboards and risk models. Reliable blockchain architecture at this layer is what makes sub-90-millisecond query latency achievable at petabyte scale.
Blockchain analytics
The practice of querying structured, indexed on-chain data to derive insights about fund flows, entity behaviour and risk. Distinct from raw blockchain data indexing, which is the prerequisite step: you cannot run analytics on data you have not yet indexed.

Frequently asked questions

What does a blockchain development company do?

A blockchain development company designs and builds software that runs on or reads from distributed ledgers. Depending on the firm, work spans smart contract engineering, blockchain application development, on-chain analytics, AML and transaction monitoring, tokenization infrastructure, DeFi protocol development, cross-chain integration and security auditing. Blockchain Stars focuses on real-time analytics and compliance intelligence: blockchain data indexing across nine chains at petabyte scale so compliance teams and risk desks can screen counterparties, detect suspicious patterns and file reports in minutes. We also act as a blockchain development partner for regulated firms that need ongoing smart contract consulting alongside their platform subscription.

How much does it cost to hire a blockchain development company?

Costs vary widely by scope. Subscription access to the Blockchain Stars analytics platform starts free (Explorer tier) and scales to USD 1,400 per month (Team), USD 4,900 per month (Compliance) and custom pricing from USD 180,000 per year (Enterprise). Bespoke build engagements for custom analytics or monitoring systems run from USD 60,000 to 240,000, depending on chain coverage, data volume and integration complexity.

How do I choose a blockchain development company?

Evaluate three things: relevant domain depth (does the team have production deployments on the chains you need?), security discipline (are contracts independently audited with zero critical findings, and is the code fuzz-tested with Foundry testing and formal verification?) and honest scope (does the firm tell you when a free block explorer would answer your question?). Blockchain Stars declines roughly 38 percent of enquiries where the need does not justify a full analytics build. Ask any prospective firm for its audit reports, production contract addresses, evidence of blockchain QA processes and a clear explanation of what it will not do. Firms that also offer blockchain strategy advice, not just build hours, are more likely to match the engagement to your actual risk obligation.

What does Blockchain Stars actually do?

We index and analyse blockchain data in real time, then turn it into compliance and risk intelligence. AML and transaction monitoring, risk scoring, sanctions screening and market surveillance for compliance teams, exchanges and risk desks. We hold 4.2 petabytes of on-chain data and answer queries with p99 latency under 90 milliseconds.

What chains do you cover?

Ethereum, Bitcoin, Tron, BNB Chain, Solana, Polygon PoS, Arbitrum, Base and Avalanche, all indexed in real time. Tron and Bitcoin matter for AML work because so much illicit value moves there, and cross-chain coverage is what catches laundering that hops between chains.

How fast is the data?

Real time. We surface alerts within seconds of an on-chain event and answer analytical queries across petabytes with p99 latency under 90 milliseconds. Speed is the product, because a transaction-monitoring alert that arrives a day late is useless.

Are your contracts audited?

Yes. We apply a security first blockchain development workflow: Slither, Mythril, Foundry testing, Halmos formal verification and smart contract test automation run in CI on every pull request. Contract test coverage gates block any merge that drops below threshold, and every one of our 78 production contracts was independently audited before deployment. There are zero critical findings in production and no funds have been lost to a Blockchain Stars contract. Upgradeability planning and permission design are scoped at architecture stage, not added after the fact.

How is your pricing structured?

Explorer is free for read-only dashboards. Team is from USD 1,400 per month for real-time analytics and alerts. Compliance is from USD 4,900 per month for AML screening, risk scoring and case management. Enterprise is custom from USD 180,000 per year. Bespoke build engagements run USD 60,000 to 240,000.

When do you say no?

We decline roughly 38 percent of enquiries. We say no when a question can be answered by a public block explorer for free, when there is no real compliance or risk need behind the request and when a token launch lacks legal counsel on securities classification.

What certifications should a blockchain development company hold for compliance work?

For regulated compliance work, look for ISO/IEC 27001 (information security management), SOC 2 Type II (security and availability controls) and any jurisdiction-specific registration your regulator requires. Blockchain Stars holds ISO/IEC 27001:2022 (certificate BST-IS-2026-9043, LRQA), SOC 2 Type II (report BST-SOC-2026-H1), ISO/IEC 27701:2019 (privacy management, BST-PIMS-2026-211) and is registered with the Isle of Man FSA as a designated business, reference DB-2026-0188.

How does a blockchain development company handle cross-chain compliance?

The gap in most compliance programmes is cross-chain laundering: value that hops between chains within minutes, which single-chain monitoring never sees. Blockchain Stars indexes nine chains in real time and traces value across chains automatically. Our Research Note BST-2026-07 shows that 64 percent of evasive laundering flows beat single-chain monitoring by hopping chains, making real-time cross-chain tracing a requirement for serious AML programmes.

What does AI add to blockchain analytics and transaction monitoring?

AI adds three things to on-chain analytics. First, machine learning risk models generalise to new laundering patterns without manual rule updates, cutting false positives by 30 to 50 percent over rule-only baselines. Second, graph neural networks improve entity clustering and address attribution accuracy on UTXO and EVM chains. Third, LLM-assisted investigation lets compliance analysts query the on-chain data in natural language, reducing investigation setup from hours to minutes. Blockchain Stars integrates all three into the core analytics platform.
