Stop fraudulent payments before they settle.
JIL's Wallet Intelligence Engine (WIE) screens every counterparty wallet in real time, before funds move. 42 on-chain and off-chain signals across 6 risk categories produce a deterministic YES, NO, or REVIEW verdict in under 200 milliseconds, signed and recorded as an immutable attestation on every settlement.
What WIE does, in plain terms.
Most fraud detection happens after the money is already gone. WIE runs before settlement, in the gap between intent and finality. If the counterparty wallet looks dirty, the transaction is blocked or held for review. No funds move until WIE returns a verdict.
Sanctions and watchlist
Cross-references the counterparty wallet against OFAC, EU, UK, and UN sanctions lists, plus known terror-finance and trafficking wallets curated by intelligence partners.
Mixer and tumbler exposure
Detects direct or one-hop exposure to Tornado Cash, Sinbad, Wasabi CoinJoins, and other mixers commonly used to obscure the origin of stolen or laundered funds.
Known-bad clusters
Flags wallets attributed to ransomware operators, exchange hacks, rug pulls, and address poisoning campaigns. Updated continuously from public and licensed feeds.
Behavioral anomalies
Looks at wallet age, transaction velocity, dust attacks, and structuring patterns that suggest the counterparty is a throwaway or burner account.
DeFi and protocol risk
Enumerates open DeFi positions, exposure to exploited protocols, and interaction with flagged smart contracts. Catches wallets that look clean but route through compromised infrastructure.
Off-chain identity signals
Optional KYC and beneficiary-binding cross-checks. Where institutional context is available, WIE matches the on-chain wallet against the off-chain identity attached to the settlement intent.
How WIE fits into a settlement.
WIE sits in the critical path between intent submission and settlement finality. Every transaction processed by JIL passes through WIE. The verdict is cryptographically signed and recorded on-chain alongside the settlement receipt.
Intent
Sender submits a settlement intent with the counterparty wallet attached.
Score
WIE collects 42 signals in parallel and computes a composite risk score.
Verdict
Engine returns YES, NO, or REVIEW with the full signal breakdown.
Attest
Verdict is signed and recorded on-chain as part of the finality receipt.
Proceed
No adverse signals. Counterparty passes all risk thresholds. Settlement clears immediately.
Hold for compliance
Elevated risk detected. Settlement is held and routed to your compliance queue for manual review within 24 hours.
Reject
Hard-block condition met. Settlement is rejected, the reason is logged, and a SAR is filed where required by jurisdiction.
Why this matters for institutional payments.
Once a payment settles, recovery is rare. The 2024 FBI IC3 report attributed $16.6B in losses to internet-enabled crime, and the bulk of that loss happened after the wire cleared. WIE moves the verification gate to the only point where it actually changes the outcome - before the funds leave custody.
For banks, fintechs, payment networks, and corporate treasuries, the value is two-fold. First, fraud is prevented at the point where prevention is still possible. Second, every settlement carries a cryptographic attestation that the verification was performed - which is what regulators, auditors, and counterparties increasingly want to see.
Built for engineers. Built for compliance. Built to ship.
