Address screening workflow (concepts)

Educational reference only. Exact limits (row counts, credit rules, field names) vary by product and release—confirm in live documentation (phalcon-compliance-documentation for Phalcon Compliance). Pair with risk-exposure-screening-concepts and behavioral-risk-screening-concepts for what engines measure.

What is being screened?

Addresses usually mean wallets or contracts on specific chains. In a VASP or platform context, these are often customer or counterparty addresses that touch your service. Proactive screening is meant to surface high-risk entities early so teams can apply policy (review, block, escalate)—not to replace legal process or law-enforcement channels.

Tags vs markers

Concept	Typical role
Tags	Human-readable labels to distinguish addresses in the UI. Often split into default tags (from the provider’s curated or verified dataset) and user-defined tags. User-defined values commonly override defaults when both exist.
Markers	Categories by attribute or behavior (for example deposit address, frozen, VIP, pending review).

System markers (often immutable in the product):

• Sourced from the provider’s risk or reference database (for example sanctioned, mixer—per vendor taxonomy).
• May be non-editable in the UI.

Custom markers (tenant-defined):

• Internal classifications your team adds.
• Usually editable; products may cap total markers per address (for example system + custom combined ≤ 5—verify in docs).

Naming of fields differs by vendor; treat the table as pattern, not a spec.

Import and screening methods

Common operational paths:

1. Single address — Enter an address; the product resolves chain metadata and pulls tags / system markers from its integrations, then you select it for ongoing screening.
2. Bulk CSV — Upload many addresses using a template from the product (chain name, address, optional tag/marker/customer id).

Typical CSV-style columns (names vary):

Field	Purpose
Chain	Exact chain identifier required by the template
Address	On-chain identifier
Tag	Optional private user tag
Marker	Optional custom marker
Customer ID	Optional internal customer key (new or existing)

Bulk uploads often have a row limit per file (for example on the order of 100 addresses—confirm current limit). After import, review success/failure rows in the UI.

Address list

Screened addresses usually appear in a list with columns such as: address, risk summary, open alerts, last screened time, markers, customer, time added, rescreen status—exact columns depend on the product.

Address details page

Drilling into one address, products commonly expose:

• Basic information — Entity/category (if modeled), chain, markers, tags, balances, aggregate inflow / outflow.
• Risk summary — High-level rollup of triggered alerts.
• Risk overview — Finer breakdown: identified risk types, exposure-style views (for example share of tainted notionals), lists of exposed or related addresses, and links to graph or trace tools where the product integrates them (vendor-specific).
• Alerts — Filterable alert history for that address.
• Audit log — Comments (collaboration) and system events (screening runs, risk changes, automation).

Common actions:

• Rescreen — Force a fresh screening run (subject to product rules and credits).
• Export KYA-style report — Pack address metadata and risk findings for internal or audit communication (not a substitute for regulatory filings).

Blacklist vs whitelist (policy lists)

Products often let operators put addresses on internal lists. Effects are policy- and product-specific; a common pattern looks like:

Blacklist (blocked / high-friction list):

• May force a high internal severity (for example critical risk tier).
• May skip ordinary periodic screening (to save credits) while still treating the address as blocked or escalated.
• May disable automatic rescreen cycles.
• May propagate severity to direct counterparties in some configurations (strong compliance implications—follow your program’s rulebook).

Whitelist (trusted / low-friction list):

• May mark the address as no or low internal risk for policy purposes.
• May exclude from standard engine passes and rescreen loops to save credits.

Caution: whitelist entries are operational decisions inside the tool—they do not change real-world illicit activity off-platform. Document approvals and review cadence.

Deleting an address

Removing an address from the inventory typically expires or closes alerts tied to that record in the product. It does not erase public-chain history. Confirm retention and audit requirements before deletion.

Guardrails

• Do not paste production customer lists, CSVs, or internal IDs into public chats.
• Do not assist with evading sanctions, mis-labeling peers, or gaming whitelist policies.
• Prefer primary legal and sanctions sources for regulatory obligations; UI risk tiers are heuristics.

Goal: a portable mental model of address screening UIs and list semantics aligned with common compliance products, without binding a specific vendor implementation.
