Blockchain monitoring tools cost either enterprise-contract money or pay-as-you-go money, and the gap between the two is wide. Enterprise screening contracts are quoted per institution and rarely published, which is exactly what makes budgeting hard. Pay-as-you-go screening is different: Phalcon Compliance publishes its ladder openly, starting at $39 a month, with screening packages from $95. Yes, free tiers genuinely exist, but they are scoped for evaluation, not operations. This page lays out both ends of the market and every rung between, using Phalcon Compliance's published pricing as the concrete ladder.
The Two Pricing Models
The category splits into two commercial shapes. The first is the enterprise subscription contract: an annual agreement covering a large institution's screening volume, monitoring seats, support, and integration work. Traditional AML platforms run on this model. Pricing is quoted case by case rather than published, and the procurement cycle runs to months. The cost that matters is not only the contract value: it is the time from "we need screening" to "screening is live." The price buys depth, but it also buys a threshold: below a certain team size, the model does not open at all.
The second shape is pay-as-you-go with a subscription ladder. You buy screening capacity in packages or a monthly tier, pay for what you consume, and upgrade when volume grows. For small and mid-sized compliance programs, this is the model that makes the category accessible at all: entry pricing sits under $100, and the decision is reversible month to month. The US requirements being paid for sit with FinCEN. The trade is straightforward, capacity is counted rather than unlimited, and volume discounts arrive by moving up the ladder instead of by negotiation.
What Free Tiers Actually Include
Free in this category is real but narrow, and the honest version of the answer states the limits as clearly as the benefits. Phalcon Compliance's free plan includes three screenings per month, restricted to ETH and TRON, returning a risk assessment per address or transaction. Email notifications are included, plus a one-time seven-day Monitor trial on a single monitored address. It excludes custom risk engines, analytics, SAR and STR report generation, and CSV export. On the tracing side, MetaSleuth's visual fund-flow tracing is free to use, including multi-hop expansion and label lookups.
What that free layer is for is evaluation: running a handful of real checks, learning what the data layer returns, and sizing the volume a team actually consumes. Free is not a compliance program. The obligations it cannot cover start from the FATF standards. Three checks a month cannot carry monitoring duties, and no free tier in the category claims to.
The Full Price Ladder
The complete published ladder for Phalcon Compliance, from free to enterprise:
- Free: 3 screenings per month, ETH and TRON only, email notifications, one-time 7-day Monitor trial.
- Pay-as-you-go Screening Packages: 50 to 2,000 screening credits, starting at $95, with a per-screening price between $1.10 and $1.90, valid for 12 months, unlocking full chain coverage, analytics, and audit report export.
- Essential: from $39 per month for 25 to 500 monthly screenings, adding SAR and STR reporting, CSV export, and ten custom risk engines.
- Scale: from $699 per month for 750 to 5,000 monthly screenings, and this is the tier where API access and webhooks open up.
- Enterprise: unlimited screening, multi-seat team collaboration, dedicated support, and Monitor included, priced by consultation.
Monitoring is priced separately as an add-on by watched-address tier. The first monitored address is free on Essential and Scale, and tiers run from 10 concurrent addresses at $60 per month up to 200 concurrent addresses at $500 per month. Annual billing discounts run roughly 15 to 17 percent across the ladder. Monitoring does not consume screening credits; the two are billed as parallel capacities.

Hidden Costs to Ask Any Vendor About
Whatever the sticker price, the costs that decide total spend sit in the questions most teams forget to ask. Setup and integration fees, which enterprise contracts often carry as a separate line. Training and onboarding, billed or simply unbudgeted in analyst time. Multi-year bundling, where the discount is real but the lock-in is the price. Per-seat charges for additional analysts, which scale with team growth rather than usage. And export and evidence costs, whether report generation and data export are included in the tier or gated above it.
The habit is to price the workflow, not the product: the number of checks, the number of watched addresses, the number of analysts, and the records the program must produce. A vendor conversation that starts from those four numbers surfaces the hidden costs before the contract does.
