Low, medium, high: how AML risk scoring of crypto wallets works

Low, medium, high: how AML risk scoring of crypto wallets works

Why does high risk not always mean criminal activity, and why does low risk not guarantee complete safety? We explain in plain language the principles behind assessing the risk of cryptocurrency wallets, the typical mistakes users make, and recommendations for individuals and businesses on how to work with screening results.

When screening a cryptocurrency wallet before sending or receiving funds, a user typically receives one of three results: Low Risk, Medium Risk, or High Risk. However, not everyone understands what exactly such an assessment means and, just as importantly, what it does not mean. We will examine in detail how the cryptocurrency compliance system is structured from the perspective of an ordinary user.

Such an assessment helps in making a decision: whether a transfer can be carried out safely, whether a more detailed review of the transaction history is required, whether additional information needs to be requested from the counterparty to the deal, or whether the operation should be temporarily suspended for further checks. At the same time, the assessment does not guarantee that the funds are entirely "clean," and it replaces neither the user's common sense nor the internal screening procedures in place at a company.

What is a cryptocurrency wallet risk score?

Put more simply, such an assessment makes it possible to understand whether the wallet is in any way linked to suspicious or potentially dangerous sources of funds, and how strong those links are.

The resulting data is consolidated into a single risk level, which is much easier to use when making decisions. The calculation takes many factors into account: where the funds came from, where they were sent, which services the wallet interacted with, and whether those services fall into higher-risk categories.

Context always matters: the very same risk level can be interpreted in completely different ways depending on the transfer amount, the purpose of the operation, the identity of the counterparty, and the specific reason that triggered the risk signal.

What the Low Risk, Medium Risk, and High Risk levels mean

To make screening results easier to interpret, three main risk levels are used: Low Risk, Medium Risk, and High Risk.

Low Risk

Such a wallet may have only minimal overlap with potentially risky addresses, or it may show the ordinary activity typical of most cryptocurrency users, without any notable connections to known dangerous categories.

This result does not guarantee that the wallet will remain safe forever, nor does it confirm the absolute "cleanliness" of the funds. The risk level can change at any moment. If funds from a questionable source later arrive at the wallet, or if it begins interacting with suspicious addresses, its risk profile will change as well.

For an ordinary user making a one-off transfer between trusted parties, a Low Risk result is often enough to proceed with the operation.

For a business, the question should be framed differently: not "does the wallet have a low risk?" but "do the company's internal rules require additional steps even at this risk level?"

Medium Risk

Medium risk can arise for a wide variety of reasons: the presence of suspicious connections, interaction with services whose purpose cannot be determined, or dealings with decentralized exchanges, infrastructure services, or other little-studied platforms. Such indicators are not in themselves proof of violations, but they do require additional analysis.

For an individual user, this is a reason to temporarily suspend the transfer, carefully examine which specific risk category triggered the assessment, and, if necessary, request additional clarification from the sender or recipient of the funds.

For companies, such a result usually means the need to carry out additional checks: requesting information about the origin of the funds, obtaining supporting documents, or referring the operation for manual analysis by specialists.

Thus, Medium Risk is not an automatic refusal to process the operation, but merely a signal that the situation requires further review.

High Risk

For an individual user, such a result means one should not rush to transfer funds. It is necessary to carefully examine the specific risk category, save the screening results, and only then decide whether to proceed with the operation.

For a business, a high risk level should trigger a predefined internal review procedure. Depending on the risk category, the circumstances of the transfer, and the company's internal requirements, this may mean temporarily suspending the operation, requesting additional explanations, imposing restrictions on the client, or referring the situation to senior financial-monitoring specialists.

It is important to remember that a high risk level cannot be treated as a standalone figure without context. It should serve as grounds for a documented review that takes into account the risk category, the specifics of the particular operation, and the anti-money-laundering policy in force within the organization.

What factors affect a crypto wallet's risk level?

When a wallet is screened, not only the final risk level is displayed, but also the signals on which it was calculated. Understanding exactly which connections led to the resulting assessment helps interpret the result correctly.

Trusted Connections

Such connections most often reflect the ordinary activity of cryptocurrency users: buying digital assets through a licensed exchange, transferring funds using well-known services, and other standard operations.

However, the presence of trusted connections does not in itself cancel out other risk factors. If, alongside them, interactions with suspicious or dangerous categories of addresses are detected, those signals also require attention.

Suspicious Connections

This does not at all mean that the wallet is being used for unlawful activity. Nevertheless, such results point to the need to examine more closely the risk category, the degree of remoteness of the connection, and the circumstances of the specific transaction before deciding whether to transfer funds.

Danger Connections

Danger connections are a significantly more serious risk indicator.

When such categories are detected, the final risk level, as a rule, rises substantially. In this case, it is recommended to conduct the most thorough analysis possible before carrying out any operations.

Why a risk score is not a final verdict

This is one of the most important points to understand when working with the risk scores of cryptocurrency wallets.

A connection to elevated-risk sources can be either direct or indirect. In the case of a direct connection, the wallet interacted directly with an address or service belonging to a high-risk category. In the case of an indirect connection, the funds may have passed through one or more suspicious addresses significantly earlier, before reaching the wallet being analyzed.

The presence of such an indirect connection does not at all mean that the wallet's current owner was involved in illegal activity. It is entirely possible that the funds passed through a risky intermediate address long before arriving at this wallet.

A risk score reflects only the information that can be established through the analysis of blockchain data. It does not make it possible to determine the wallet owner's intentions, their awareness, or the legality of their actions. This is precisely why context is so important when interpreting the results.

The following should be taken into account:

  • the transfer amount;
  • the direction of the movement of funds;
  • the purpose of the operation being carried out;
  • whether the identity of the counterparty is known;
  • which specific risk category triggered the signal.

How individuals should use the risk score before sending or receiving cryptocurrency

Once the funds have already been sent, the ability to influence the situation is significantly reduced. A preliminary check makes it possible to obtain the necessary information in advance and to make an informed decision before carrying out the operation. After the check is complete, attention should be paid not only to the overall risk level, but also to which specific category or connection caused that result.

For example, two wallets may receive the same Medium Risk score, yet the reasons will be completely different. In one case it may be caused by interaction with an unknown service, and in another by suspicious transaction patterns.

If the check showed Medium Risk or High Risk, it is recommended not to make a decision right away. Depending on the situation, it makes sense to:

  • request additional clarification from the sender or recipient of the funds;
  • assess whether the transfer amount justifies the potential risks;
  • save the screening results in case questions or disputes arise in the future.

If a significant amount of time has passed since the previous check, or if the wallet has been actively used and has received new transactions, it should be checked again. The risk level is not a constant value. As new operations occur and interactions with other addresses take place, the risk profile can change substantially.

How companies should use wallet risk scores in AML procedures

The resulting risk level should be built into the company's internal procedures, which determine in advance what actions need to be taken in each specific case. At a low risk level (Low Risk), operations can usually be processed in accordance with standard internal rules.

A medium risk level (Medium Risk), as a rule, requires additional review. This may include:

  • requesting information about the origin of the funds;
  • analyzing the circumstances of the specific transaction;
  • additional screening of the client or counterparty;
  • enhanced monitoring of subsequent operations.

A high risk level (High Risk) should trigger a pre-approved response procedure. This may involve examining the specific risk category, assessing the circumstances of the transfer, and deciding whether to suspend the operation, restrict service to the client, refer the situation to senior specialists, or refuse to carry out the transaction entirely in accordance with the organization's internal policy.

The risk level on its own does not make it possible to meet the requirements of anti-money-laundering legislation. It merely provides a signal of potential risk, whereas the final decision should be made within the framework of internal financial control procedures.

8 common mistakes in interpreting a crypto wallet's AML score

Treating Low Risk as a guarantee of complete safety

A low risk level reflects the state of a wallet solely at the time the check is carried out. This does not mean the wallet will remain safe in the future. If it subsequently begins interacting with new addresses, its risk profile may change significantly.

Treating Medium Risk as proof of fraud

A medium risk level only indicates the presence of factors that deserve additional attention. It does not confirm that the wallet's owner is engaging in unlawful actions. The right decision always depends on the specific risk category and the circumstances of the operation.

Ignoring the reason the risk score appeared

The risk level itself is merely a brief summary designation. What truly matters are the reasons that led to that assessment: sanctioned addresses, interaction with mixers, unknown services, or other risk categories. That is why one should always analyze the details of the check rather than limit oneself to the Low, Medium, or High Risk label alone.

Analyzing only a single wallet without taking the context of the operation into account

A wallet does not exist in isolation. When interpreting a result, it is necessary to take into account:

  • the transfer amount;
  • the direction of the movement of funds;
  • information about the counterparty;
  • the purpose of the payment.

Without this, it is impossible to correctly assess the resulting risk level.

Checking a wallet only after the funds have been sent

A check carried out after a transfer has been made can no longer change the outcome of the operation. It is precisely a preliminary check that provides the opportunity to decline a transfer or request additional information before the funds are sent.

Not saving the screening results

If a bank, a cryptocurrency exchange, or a counterparty later raises questions about the origin of the funds, a saved screening report can serve as important evidence of the due diligence exercised. One should not rely solely on memory in such situations.

For companies: closing alerts without documented justification

Dismissing a high-risk alert without recording the reasons for that decision is considered a serious deficiency in the internal control system. Documenting why a particular decision was made is no less important than the decision itself.

For companies: using the same procedure for all risk levels

Low, medium, and high risk levels call for different response scenarios. If the same course of action is applied to all situations, the risk assessment system itself loses its practical value.

When should you re-check a cryptocurrency wallet?

The result of a check reflects the state of blockchain data only at the moment it was carried out. Cryptocurrency wallets are constantly changing: they receive new inflows, send funds, interact with other addresses, and gradually accumulate new transaction history.

For this reason, a check performed several weeks or months ago may no longer reflect the actual risk level.

The main point: how to read a risk score correctly

A cryptocurrency wallet's risk score is one of the most practical tools for analyzing potential risks before interacting with a cryptocurrency address.

The Low Risk, Medium Risk, and High Risk levels are merely signals that summarize the results of the analysis. They are not permanent characteristics of a wallet, legal conclusions, or a guarantee of the safety or illegality of the funds.

For individual users, the best practice remains checking a wallet before sending or receiving cryptocurrency, carefully examining the reasons that influenced the final assessment, and repeating the check when circumstances change.

For companies, a risk score should be used as part of a formalized AML system, in which each risk level corresponds to a predefined course of action, all decisions are documented, and the results of the analysis are considered only together with information about the transaction and the counterparty, rather than in isolation from one another.
