AML Risk Categories

This page describes the AML risk categories used in the BitOK KYT platform. Each category reflects the primary nature of an entity or service observed on the blockchain and helps assess its AML/CFT risk profile.

Disclaimer

Risk levels shown here are general guidelines. The actual risk of a specific address, transaction, or entity depends on context, volume, behaviour over time, and applicable regulation.


Risk Levels Legend​

LevelDescription
πŸ”΄High risk

Categories typically associated with serious predicate offences (sanctions, child abuse material, darknet markets, fraud, terrorist financing, large hacks, etc.). These flows usually require enhanced due diligence and may be unacceptable for regulated institutions.

🟑Medium risk

Categories that significantly increase AML risk but are not always criminal by design (mixers, privacy protocols, unlicensed gambling, ICOs, certain P2P activity). These often trigger additional review, monitoring, or limitations.

🟒Lower risk

Standard, broadly legitimate services (regulated exchanges, PSPs, marketplaces, mining, infrastructure). They can still be abused, but risk is primarily driven by counterparties and behaviour, not by the category itself.

βš™οΈSystem

Technical or neutral labels used by BitOK (e.g. Dust, Undefined, Seized funds) to describe how the data is treated inside the platform rather than the inherent AML risk.


High-Risk Categories​

CategoryRiskDescription
Child Abuse Material (CAM)πŸ”΄High risk

Entities distributing or facilitating access to child sexual abuse material, usually via darknet forums and hidden services.

Darknet MarketπŸ”΄High risk

Marketplaces on Tor / I2P selling illegal goods and services such as narcotics, weapons, counterfeit documents, and stolen data.

Fraud ShopπŸ”΄High risk

Single-vendor markets selling stolen personal data, cards, credentials, or identity documents. Behaviour differs from multi-vendor darknet markets.

Illegal ServiceπŸ”΄High risk

Services directly supporting criminal activity (darknet operations, hacking groups, terrorist networks, illegal goods distribution, etc.).

ScamπŸ”΄High risk

Fraudulent schemes including fake exchanges, investment platforms, Ponzi schemes, phishing and extortion campaigns pretending to be legitimate services.

Stolen FundsπŸ”΄High risk

Addresses holding proceeds of theft or hacks (e.g. exchange hot-wallet breaches, protocol exploits, compromised customer wallets).

RansomwareπŸ”΄High risk

Wallets and services associated with ransomware operators and ransom payments collected from victims.

Terrorist FinancingπŸ”΄High risk

Entities involved in raising, moving, or holding funds for terrorist groups and affiliated individuals.

High-Risk JurisdictionπŸ”΄High risk

Crypto entities based in jurisdictions under comprehensive sanctions or embargoes (e.g. OFAC-sanctioned countries and regions).

SanctionsπŸ”΄High risk

Individuals or entities listed on sanctions lists (OFAC SDN, EU, UN, etc.) where dealing with them is prohibited or heavily restricted.

Online PharmacyπŸ”΄High risk

Services selling controlled or unregulated pharmaceuticals, often without prescriptions and sometimes overlapping with darknet markets.

GamblingπŸ”΄High risk

Unlicensed or weakly-regulated online gambling platforms (casinos, betting sites, games of chance) lacking effective AML/KYC controls.

High-Risk ExchangeπŸ”΄High risk

Exchanges with no mandatory KYC, known links to illicit services, or substantial involvement in laundering and high-risk flows.


Medium-Risk Categories​

CategoryRiskDescription
Mixer🟑Medium risk

Mixing / tumbling services that obfuscate links between inputs and outputs by pooling and redistributing funds.

Privacy Protocol🟑Medium risk

Protocols and assets with built-in privacy features (e.g. Monero, Secret) where counterparties are hidden by design.

P2P Exchange🟑Medium risk

Peer-to-peer trading platforms connecting individual buyers and sellers. Some do not enforce KYC, making them attractive for layering and ML.

DEX🟑Medium risk

Decentralized exchanges enabling token swaps via smart contracts, without centralized custody. Popular among both legitimate users and bad actors.

Lending🟑Medium risk

Lending/borrowing protocols where users provide collateral and borrow against it. Over-collateralization reduces credit risk, but flows may still require monitoring.

Bridge🟑Medium risk

Cross-chain bridges transferring value between blockchains. Frequently targeted by exploits and used to move value between ecosystems.

ICO🟑Medium risk

Initial Coin Offering platforms raising funds for new projects. Many ICOs have been fraudulent or non-compliant, so flows require careful assessment.

Enforcement Action🟑Medium risk

Entities subject to court proceedings, regulatory enforcement or other official legal actions by authorities.


Standard & Lower-Risk Service Categories​

CategoryRiskDescription
Exchange🟒Lower risk

Centralized exchanges and brokers allowing users to buy, sell and trade cryptocurrency. Risk depends heavily on licensing and KYC quality.

Payment Service Provider🟒Lower risk

PSPs / payment gateways processing crypto payments for merchants and businesses.

Marketplace🟒Lower risk

Online stores selling legitimate goods and services, accepting crypto as a payment method.

Mining🟒Lower risk

On-chain entities receiving block rewards for proof-of-work mining.

Mining Pool🟒Lower risk

Pooled mining services distributing rewards to participating miners. Risk increases if the pool also accepts unrelated deposits.

IaaS🟒Lower risk

Infrastructure-as-a-Service providers (VPN, VPS, domain registrars, hosting and other technical infrastructure services).

Personal Wallet🟒Lower risk

Verified wallets belonging to identified end-users.

Custodial Wallet🟒Lower risk

Hosted wallets where a service controls private keys on behalf of customers (hot wallets, omnibus wallets).

Token Contract🟒Lower risk

Smart contracts representing fungible or non-fungible tokens (e.g. ERC-20, ERC-721). Used as technical anchors rather than service providers.

Smart Contract🟒Lower risk

General-purpose contracts with custom logic (vaults, protocols, automated services) not falling into a more specific category.

NFT Marketplace🟒Lower risk

Platforms focused on minting, listing and trading NFTs. Depending on design, may overlap with DEXs or smart-contract platforms.

ATM🟒Lower risk

Crypto ATM operators allowing cash–to–crypto and crypto–to–cash conversion.
