FORENSIC REPORT

TIME OF DEATH

Time of death: December 21, 2020, approximately 3:47 AM UTC. The specimen—iProtocol token contract on Ethereum mainnet—appeared healthy at deployment. Initial liquidity was seeded properly. Investors participated in presale, funds were received. All vital signs nominal. Then the deployer's wallet began moving.

CAUSE OF DEATH ANALYSIS

Technical cause of death: The increaseAllowance() function, ostensibly a routine ERC-20 mechanism for token approvals, concealed a lethal payload. Rather than limiting allowances, this function operated as a hidden mint gate. The deployer weaponized it to conjure new tokens ex nihilo directly into their wallet without triggering standard Transfer events in the expected manner. This is the murder weapon. The autopsy reveals the tokens were then systematically liquidated across three separate transactions, converting fresh inventory into ETH at the expense of legitimate holders whose positions were instantly diluted into worthlessness.

CONTRIBUTING FACTORS

Contributing factors: The contract code itself was the warning sign no one read. A cursory audit would have flagged the increaseAllowance() override. The presale structure—gathering funds first, then deploying liquidity—created the perfect conditions for post-launch exploitation. No timelock. No multisig. No external verification. The deployer maintained god-mode access throughout. This wasn't negligence; this was premeditation with extra steps.

VICTIM IMPACT

Victim impact: Forty-one thousand, nine hundred thirty dollars. Gone. Distributed across an unknown number of retail investors who believed in a project that existed only as bait. Each transaction that dumped tokens was a gunshot wound to the portfolio of someone who couldn't see it coming.

PATHOLOGIST'S NOTE

Pathologist's note: I've examined thousands of corpses in the crypto morgue, and they blur together—but this one stays with me. Not because it was sophisticated. It wasn't. It stays because it was so *obvious* in hindsight. The increaseAllowance() trick is ancient. It's like watching someone die from a stab wound when the knife was labeled 'KNIFE' on the blockchain. The real killer here wasn't technical complexity—it was trust. They trusted the name. They trusted the presale structure. They trusted that someone, somewhere, had looked at the code. Nobody had. The body is still cooling on the slab.

"iProtocol's increaseAllowance() function harbored a fatal secret: unlimited token generation. Deployer minted and dumped, leaving $41,930 in unrecoverable losses. A textbook rug with obfuscated mechanics."
