Stolen/Scammed Asset Recovery Cases
Real-world case files by Delta & Capital's forensics team: penetrating complex money laundering webs to protect asset integrity.
Case Summary & Background
The victim's wallet was compromised via a phishing drainer, losing 119.78 ETH which was split and deposited into a fixed-denomination mixer (Mixer M). The hacker later withdrew the funds and routed them to Exchange D. Since native ETH has no contract blacklist freeze capability, the only chance of recovery was locking the exchange account before the hacker off-ramped. Delta & Capital utilized a probabilistic demixing engine to match deposit-withdrawal links and secured an emergency account block within 96 hours, recovering 119.78 ETH.
Case Profile
| Forensic Agency | 德尔泰 (Delta & Capital) |
|---|---|
| Stolen Assets | 119.78 ETH |
| Chain Ledger Path | Ethereum Single-Chain |
| Typologies | Phishing drainer, fixed-denomination mixer pool, gas funder clustering, exchange attribution |
| Control Signals | Shared Gas Funder Address providing initial gas to multiple withdrawal addresses |
On-Chain Flow & Forensic Mapping
While mixers sever direct links, we structured a probabilistic model analyzing denomination matches, deposit-withdrawal windows, and shared gas-payers. By clustering withdrawals based on shared gas sources, we grouped independent addresses back into a single malicious entity.
KYT Risk Matrix
| Hop | Interaction | Laundering Indicators | Risk Level |
|---|---|---|---|
| Hop 1 | Victim → Drainer address | Unsigned asset transfer / phishing harvest (Drainer Harvest) | HIGH |
| Hop 2 | Deposit into Mixer M contract | Interaction with sanctioned high-anonymity address (Mixer Deposit) | CRITICAL |
| Hop 3 | De-mixing model / Gas correlation | Shared gas first-funding source clustering (Gas Funder Match) | INFO / PROBABILITY |
| Hop 4 | Layered peeling after withdrawal | Multiple split transfers to obscure the trail (Peeling hops) | HIGH |
| Hop 5 | Exchange D deposit gateway | Gateway off-ramp cash-out (VASP deposit entry) | CRITICAL |
Recovery Pathway & Judicial Restitution
Outcome Record: Since ETH lacks native blacklist triggers, we designed our search to lock the gateway entry. Exchange D locked the target account within 96 hours of our emergency filing. Following a 14-month legal process, the 119.78 ETH was fully refunded to the victim.
Case Summary & Background
The victim lost 295,590 USDT (BEP-20) in a "Sha Zhu Pan" investment scam. The fraudsters structured and split the funds on BNB Smart Chain (BSC), bypassed AML filters via a cross-chain bridge into TRON (TRC-20), and deposited them to a major exchange (Exchange A). Delta & Capital traced the flows, reconstructed the source of wealth (SOW) proving the victim's ownership, and coordinated with law enforcement and Exchange A to enforce a freeze, civil forfeiture, and full restitution to the victim.

| Stolen Assets | 295,590 USDT |
| Chain Ledger Path | BNB Smart Chain (BEP-20) → TRON (TRC-20) |
| Typologies | Peel chain layering, cross-chain bridge, TRON activation clusters, VASP deposit attribution |
| Control Signals | Shared TRON activation parent address & shared energy delegation source |
On-Chain Flow & Forensic Mapping
We combined TRON resource model finger-printing (shared activation and energy delegate) with cross-chain bridge reconciliation. Both distinct lines of evidence converged to target a single entity, elevating the attribution confidence to meet strict judicial evidence standards.
KYT Risk Matrix
| Hop | Interaction | Laundering Indicators | Risk Level |
|---|---|---|---|
| Hop 1 | Victim → BSC consolidation | Rapid consolidation of scam proceeds (Scam Consolidation) | HIGH |
| Hop 2 | Peel-chain layering on BSC | Change-splitting to evade large-amount compliance alerts (Peel chain layering) | HIGH |
| Hop 3 | BSC → TRON cross-chain bridge | Cross-ledger obfuscation path (Cross-ledger hopping) | HIGH |
| Hop 4 | TRON-side consolidation (shared energy/activation) | Single-controller clustering fingerprints (Attribution finger-prints) | INFO / FOCUS |
| Hop 5 | Exchange A deposit gateway | Off-ramp cash-out (VASP deposit entry) | CRITICAL |
Recovery Pathway & Judicial Restitution
Outcome Record: Within 6 business days of report submission, Tether and Exchange A issued a freeze. Following civil forfeiture proceedings, the claim was resolved in favor of the victim. 295,590 USDT was returned in full to the victim's safe wallet. The entire process took approximately 12 months.
Case Summary & Background
The victim was defrauded of 108,743 USDT by a fake stablecoin arbitrage scheme. The scammers routed funds through complex chain-hopping: executing multiple swap hops (USDT→USDC→wrapped asset) via EVM DEXs, crossing onto TRON through a bridge, converting back to USDT (TRC-20), and depositing into Exchange C. Delta & Capital decoded the DEX swaps and performed lock-release event matching on the bridge logs to link the ledgers. We then initiated dual blacklist & exchange freezes to return the full amount.

| Stolen Assets | 108,743 USDT |
| Chain Ledger Path | EVM (BEP-20 / ERC-20) → TRON (TRC-20) |
| Typologies | DEX multi-hop swap, chain-hopping, bridge lock-release matching, VASP deposit clustering |
| Control Signals | Strict temporal & value reconciliation between EVM bridge burn and TRON bridge release events |
On-Chain Flow & Forensic Mapping
Chain-hopping is designed to render single-chain tracers useless. We reconciled bridge events using automated scripts to match burn logs on EVM and release logs on TRON based on token value, transaction delays, and smart contract counterparties.
KYT Risk Matrix
| Hop | Interaction | Laundering Indicators | Risk Level |
|---|---|---|---|
| Hop 1 | Victim → EVM receiving address | Scam proceeds credited (Laundering Entry) | HIGH |
| Hop 2 | Multi-step DEX swaps | Stripping stablecoin freezability; laundering the assets (Asset conversion) | HIGH |
| Hop 3 | EVM → TRON cross-chain bridge | Cross-ledger obfuscation (Chain-hopping) | HIGH |
| Hop 4 | TRON-side swaps and consolidation | Rebuilding stablecoin positions and re-consolidating (Re-consolidation) | HIGH |
| Hop 5 | Exchange C deposit gateway | Off-ramp cash-out (VASP deposit entry) | CRITICAL |
Recovery Pathway & Judicial Restitution
Outcome Record: Since the assets were reconverted to TRC-20 USDT, we leveraged both the contract blacklist and gateway locks. Dual-locks were executed within 7 business days. Following an 11-month international forfeiture case, the 108,743 USDT was returned in full to the victim.
Case Summary & Background
The victim fell prey to a fraudulent contract investment portal, transferring 327,684 USDT (TRC-20) in 4 batches. The criminals split the funds inside TRON using peel chains: they activated dozens of sub-addresses using a single activation parent address, delegated energy from a shared TRX resource pool to avoid burning fees, and structured deposit chunks to Exchange B. Delta & Capital traced the flows, assisted the judicial authorities in submitting a forensic package to Tether, and triggered the "freeze-burn-reissue" protocol to recover the assets.

On-Chain Flow & Forensic Mapping
In account-based ledgers, clean and illicit tokens mix. We implemented dual-attribute (haircut & FIFO) taint-propagation tracking to measure the pollution ratio at each peel hop, proving tracing continuity for small estrutured deposits.

| Hop | Interaction | Laundering Indicators | Risk Level |
|---|---|---|---|
| Hop 1 | Victim → initial consolidation | Rapid aggregation of scam assets (Deposit Entry) | HIGH |
| Hop 2 | Peel-chain splitting | Change-splitting to stay under AML thresholds (Peeling structuring) | HIGH |
| Hop 3 | Activation source + energy-proxy correlation | Attributed to a single controller's fingerprints (Attribution finger-prints) | INFO / FOCUS |
| Hop 4 | Exchange B deposit gateway | Off-ramp cash-out (VASP deposit entry) | CRITICAL |
Recovery Pathway & Judicial Restitution
Outcome Record: Leveraging Tether's blacklist-burn-reissue protocol, we assisted law enforcement in issuing a formal order. Tether blacklisted the address, burned the 327,684 USDT, and reissued it to the government custodial wallet. Funds were returned in full to the victim. The process completed in 6 months.
