Illicit cryptocurrency addresses received at least $154 billion in 2025, a 162% jump from the previous year, according to Chainalysis’s 2026 Crypto Crime Report, even as illicit activity stayed below 1% of total attributed transaction volume.
The figures point to a broader trend: a growing, decentralized web of blockchain analytics tools, exchange compliance systems and government investigators that is making it increasingly possible to trace cryptocurrency transactions long after they occur.
How the Crypto Intelligence Network tracks transactions
The foundation of the Crypto Intelligence Network is the transparency of public blockchains. Bitcoin and Ethereum transactions are recorded on distributed ledgers that can be examined long after a transaction occurs.
Although wallet addresses generally do not display the names of their owners, investigators can track the movement of funds between addresses. A transaction may move through multiple wallets before reaching a centralized exchange, bridge or other crypto service.
Blockchain analytics firms can analyze these movements to identify patterns and potentially associate addresses with particular entities or activities.
That capability has made blockchain data increasingly valuable to law enforcement and regulators investigating financial crime, sanctions evasion and other illicit activity.
Chainalysis reported that sanctioned entities received 694% more cryptocurrency in 2025 than in 2024. The company also identified the growing role of stablecoins in illicit transactions.
The rise of this Crypto Intelligence Network does not mean every blockchain transaction can automatically be tied to a person’s identity. Instead, it creates multiple opportunities for investigators to connect pseudonymous on-chain activity with information held elsewhere.
Stablecoins become a major focus
Stablecoins are becoming an increasingly important component of the Crypto Intelligence Network, particularly because of their growing role in cryptocurrency transactions.
According to Chainalysis, stablecoins accounted for approximately 84% of illicit cryptocurrency transaction volume in 2025. Their use has consequently attracted greater attention from regulators, blockchain analytics companies and law enforcement agencies.
Sanctions evasion is one area under scrutiny. Chainalysis said the ruble-backed A7A5 stablecoin processed approximately $93.3 billion in transactions in less than one year.
Iran-linked cryptocurrency activity has also emerged as a major concern. Chainalysis estimated that Iran’s Islamic Revolutionary Guard Corps and associated networks received more than $3 billion in cryptocurrency during 2025.
These figures illustrate why stablecoin transactions have become increasingly relevant to financial intelligence efforts. Unlike physical cash, blockchain-based transactions can leave a permanent record that investigators may analyze retrospectively.
The growing Crypto Intelligence Network is consequently extending beyond Bitcoin-focused investigations toward stablecoins, self-hosted wallets and transactions that may never pass through a conventional financial institution.
Exchanges add the identity layer
Centralized cryptocurrency exchanges provide another critical component of the Crypto Intelligence Network because they can hold information collected through Know Your Customer procedures.
Regulated exchanges typically require customers to provide identifying information when opening accounts. When cryptocurrency moves from a blockchain address into an exchange, investigators may, subject to applicable legal procedures, use exchange records to connect the address with a verified customer account.
This creates an important bridge between on-chain and off-chain information.
Blockchain analytics can reveal where funds moved, while exchange records may provide information about who controlled an account at a particular point in the transaction chain.
The result is an intelligence structure that combines transaction histories with compliance information. It does not eliminate the pseudonymous nature of many blockchain addresses, but it can make some users and transactions significantly easier to investigate.
For the broader Crypto Intelligence Network, this connection between blockchain records and centralized platforms represents one of the most important developments in cryptocurrency surveillance.
FATF expands scrutiny beyond exchanges
The Crypto Intelligence Network is also moving beyond centralized exchanges as regulators examine activity involving self-hosted wallets and peer-to-peer transactions.
In March 2026, the Financial Action Task Force published recommendations addressing stablecoins and peer-to-peer transactions involving unhosted wallets. FATF said more than 250 stablecoins were circulating by mid-2025, with their combined market capitalization exceeding $300 billion.
The recommendations encouraged governments and private-sector companies to strengthen monitoring and risk controls around stablecoin transactions.
This broader approach reflects the changing structure of the cryptocurrency market. Investigators can no longer focus exclusively on centralized exchanges because users can transfer assets directly between self-hosted wallets and interact with decentralized or cross-chain services.
That creates challenges for the Crypto Intelligence Network, particularly where transactions move through mixers, cross-chain bridges or privacy-enhancing technologies.
These tools can make financial investigations more difficult, but they do not necessarily erase the underlying blockchain record.
The distinction is important for cryptocurrency users. The source material puts it plainly: “pseudonymity should not be confused with guaranteed anonymity.”
As blockchain analytics develops and more companies cooperate with regulators and law enforcement, the infrastructure surrounding cryptocurrency is becoming increasingly observable. The emerging Crypto Intelligence Network is not a single global database, but a combination of technologies, records and institutions capable of connecting pieces of information that once existed separately.
