Web3 institutions

Worldwide, regulatory bodies have established rigorous laws and guidelines to oversee the movement of money, aiming to combat illicit activities such as money laundering, fraud, and the financing of terrorism.

Despite these efforts, a surge in high-profile scandals, exemplified by incidents like the FinCEN Files, exposes significant compliance failures within top financial institutions. The United Nations estimates that approximately 2–5% of global GDP, amounting to $800 billion to $2 trillion dollars annually, is involved in money laundering—a figure that could be double the total market capitalization of the web3 blockchain-based cryptocurrency sector. The imperative for effective compliance systems is more evident than ever.

In the traditional finance sector (TradFi), centralized systems play a pivotal role in monitoring transactions and ensuring compliance. However, compliance with Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations imposes substantial costs in terms of compliance specialists’ salaries and operational expenses.

Unlock the potential of digital assets for your institution

The collective expense of financial crime compliance measures surpasses a quarter of a trillion dollars annually and continues to rise. Solutions such as transaction screening can help combat such challenges. 

What is Transaction Screening?

Transaction Screening scrutinizes transactions for suspicious or prohibited activity prior to approval. If the analysis of the respective blockchain infrastructure verifies illicit or excessively risky behavior, the transactions are halted. This is crucial for thwarting blatant attempts to circumvent regulations, including international sanctions. Additionally, it contributes to a layered, risk-based approach to Anti-Money Laundering/Countering the Financing of Terrorism (AML/CFT) due diligence.

What are the Benefits of Transaction Screening?

Transaction screening of blockchain cryptocurrency is crafted to prevent financial crimes effectively. To accomplish this, it scrutinizes various aspects of a transaction, ensuring it is not conducted on behalf of sanctioned individuals or within restricted jurisdictions. Some advantages of digital crypto wallets with transaction screening capabilities include:

  1. Facilitating real-time detection of criminal transactions by financial institutions.
  2. Speeding up the remediation process.
  3. Flagging suspicious activities for further investigation on Ethereum and polygon blockchain.
  4. Assisting financial institutions in meeting regulatory requirements.

Why transaction screening is required in Web3?

Transparency is more than just a trend in the blockchain cryptocurrency industry. It is a fundamental element of regulatory compliance. Within the cryptocurrency industry, Web3’s inherent transparency arises from its public and immutable blockchain records. This characteristic proves instrumental in risk management, facilitating the comprehensive due diligence necessary for monitoring cryptocurrency transactions. Employing machine learning, the best web3 crypto enterprises can efficiently sift through transaction data, identifying potentially suspicious activities that may signal money laundering or involvement with sanctioned entities.

In the pursuit of cryptocurrency compliance, forward-thinking Web3 companies bear the responsibility to proactively align with regulations. This involves adopting wallets for cryptocurrency with advanced transaction monitoring software, implementing know your transaction (KYT) protocols, and consistently updating their anti-money laundering (AML) solutions.

The traditional financial sector has long grappled with the imperative for rigorous compliance, particularly to attract institutional investors. In the realm of Web3 and the broader blockchain cryptocurrency industry, compliance transcends being merely a regulatory necessity; it stands as a competitive advantage. Institutional investors prioritize reliability, and crypto compliance offers precisely that, leveraging both custodial and non custodial wallets with advanced anti-money laundering (AML) solutions and transaction monitoring software.

Transparency emerges as a pivotal factor in gaining the trust of institutional players. The openness of web3 blockchain data establishes a level of trust often absent in traditional financial systems. With a transparent ledger of cryptocurrency transactions, institutions can conduct their own thorough due diligence. This approach provides unparalleled depth, enabling them to assess the effectiveness of a Web3 business’s risk management strategies and ensuring they avoid involvement with financial crimes or money laundering activities.

Relevant Attributes for Screening: Identify and determine which data elements are pertinent for screening against specific sanctions risk.

Sanctions Data/Screening Setup: Establish a risk-based assessment of transactions over Ethereum and polygon blockchain to determine relevant sanctions lists. Implement list management systems to manage and reduce false positives. Ensure timely updates of lists and enhance data with additional information.

Screening Intervals: Define screening intervals based on internal policies, with screening during new relationship establishment and regular intervals or trigger events. Perform transaction screening of the entire blockchain infrastructure before potential violations, paying attention to points in the transaction process susceptible to information alteration.

Handling Matches: Recognize that an alert during screening indicates a potential match but doesn’t confirm a sanctions risk. Manually review client identity information against the sanctions list. Approach the client for additional information if needed. If a positive match is confirmed, report to the internal compliance or reporting officer, suspending all transactions. If the match is deemed a false positive, consider whitelisting the client’s name to prevent future matches.
