--- title: "Know Your Transaction: What It Is and Why It Matters" excerpt: "What KYT is, why regulators require it, and how businesses use it to monitor risk on-chain." category: Crypto Compliance banner: /images/insights/know-your-transaction.png published: 2026-08-20 --- Every crypto business runs Know Your Customer checks at signup. Far fewer track what happens after that customer starts moving money. That gap is exactly what Know Your Transaction, or KYT, is built to close. ## What KYT actually is KYT is the ongoing monitoring and risk-scoring of transactions on the blockchain, rather than a one-time check on the person behind them. Where KYC verifies identity at onboarding, KYT looks at the money itself: where it's coming from, where it's going, and what it has touched along the way. In practice, KYT platforms work through a few connected steps. They pull transaction data from the blockchain in real time and link wallet addresses to known real-world entities, whether that's a licensed exchange, a sanctioned wallet, a darknet market, or a mixer. Each transaction gets a risk score based on its exposure to those entities, both directly and through several hops removed. Behavioral models flag patterns that look like structuring or layering, even when no single transaction trips a static rule. And when something crosses a risk threshold, it generates an alert with enough evidence attached for a compliance team to actually investigate and act on. The forensic techniques behind this are what separate serious KYT from a basic blacklist check. Wallet clustering groups thousands of addresses back to a single controlling entity. Taint analysis traces funds backward to measure how much of a wallet's history connects to illicit sources. Cross-chain tracing follows assets as they hop between networks, since criminals increasingly move funds from Bitcoin to Ethereum to Solana specifically to break a paper trail that only covers one chain. ## Why it matters The volume of illicit activity on-chain is the plain reason regulators care. Chainalysis put the total received by illicit addresses at roughly $40.9 billion in 2024. That's money tied to ransomware, sanctions evasion, fraud, and terrorist financing moving through the same rails as everything else, and it's exactly what a KYC check at signup won't catch, because the person who opened the account can look completely clean while the transactions that follow don't. Regulators have caught up to this distinction. FATF Recommendations 15 and 16 form the baseline requirement across jurisdictions. In the EU, MiCA sets the licensing and governance framework for Crypto Asset Service Providers, but the actual transaction monitoring mandate sits in the EU's separate AML rulebook, the AML Regulation and AMLD6 (Regulation (EU) 2024/1624 and Directive (EU) 2024/1640), which applies in full from July 2027. The UK's FCA requires ongoing monitoring for registered crypto businesses, FinCEN requires it for virtual currency MSBs under the Bank Secrecy Act, and VARA, MAS, FINMA, and Japan's FSA all impose equivalent requirements on licensed VASPs in their markets. None of these treat KYC as sufficient on its own. The expectation is continuous monitoring of what happens after onboarding, and regulators are increasingly checking whether those controls actually work in practice, not just whether alerts get generated. There's a second, more commercial reason KYT has become unavoidable: banks are starting to demand it from the crypto businesses they bank. A crypto exchange or payment processor that can't show clean KYT logs is a much harder business to keep fiat rails open for, which means transaction monitoring has become a condition of staying banked, not just a regulatory checkbox. ## How businesses are using it Exchanges and other Crypto Asset Service Providers lean on KYT to catch what identity checks miss. A user can pass KYC cleanly and still route funds through a mixer toward a ransomware wallet within minutes of their account going live. KYT is what flags that behavior, because it's watching the transaction pattern rather than the person's paperwork. Banks and traditional financial institutions offering crypto custody or digital asset services use KYT to satisfy the same transaction monitoring expectations regulators already hold them to on the fiat side. Payment providers screen inbound transactions before settlement, so they're not left holding funds that turn out to be tied to a sanctioned wallet after the fact. Asset managers run KYT checks on counterparties before larger transactions settle, treating it as standard counterparty risk work rather than something specific to crypto. The operational upside is real too. AI-driven KYT that models normal behavior per user, rather than relying purely on static rules, is reported to cut manual investigation time by 40 to 50% at firms that have adopted it, per industry reporting from KYC-Chain. Chainalysis has separately cited a case in which one derivatives exchange using its KYT product cut AML risk exposure by 88%. A single vendor's case study isn't proof of a universal outcome, but the direction is consistent: for compliance teams that are usually understaffed relative to transaction volume, a well-tuned KYT setup is the difference between reviewing every alert properly and drowning in false positives. ## The shift underway The direction of travel is consistent across every source: KYC answers who your customer is once, at the start. KYT answers what your customer's money is actually doing, continuously. As the EU's AML rulebook and the FATF Travel Rule push transaction-level compliance further into force through 2027, KYT is moving from a nice-to-have for well-resourced exchanges to a baseline requirement for any business that touches crypto, whether that's a VASP, a bank, a payment processor, or a fund settling counterparty trades. ## Where Inter X fits in Inter X built its KYT check around that gap between onboarding and ongoing risk. Submit the chain, asset, destination, and transaction hash, and get a pass/fail signal back. No onboarding call required to start using it. It sits alongside two related checks in the same dashboard. Know Your Entity screens exchanges, VASPs, and counterparties on risk, licensing, executives, and adverse media. Address Prescreening validates a destination wallet before funds go out, without needing a transaction hash yet, so you can catch a problem before you send rather than after. Access is fully self-serve. Sign up with a name, org, and email, and you're in the dashboard immediately, no sales call and no minimum contract. The Standard plan is $120/month for 100 credits (a KYT check runs 2 credits), Premium is $449/month for 600 credits, and Enterprise is custom. New accounts get 5 free credits and a 3-day window in the dashboard before they need to subscribe. That's a different model from the sales-led incumbents in this space, where per-check pricing is usually hidden behind a call and a proposal. For a smaller VASP, OTC desk, or payments team that wants to start running KYT checks without a procurement cycle, that's the practical difference: you can be checking your first transaction the same day you sign up.
