How much was lost in the Elongate Deluxe hack?

The Elongate Deluxe hack resulted in $230K in losses on August 08, 2021.

What attack technique was used in the Elongate Deluxe exploit?

The Elongate Deluxe exploit utilized Rugpull. Understanding this attack vector is critical for smart contract auditors and developers building secure DeFi protocols.

How can developers prevent similar smart contract attacks?

Preventing smart contract hacks requires a combination of secure coding practices, thorough security audits, and understanding common attack vectors like reentrancy, oracle manipulation, and access control flaws. Smart Contract Hacking (SCH) provides hands-on training to help developers and auditors identify and prevent vulnerabilities before deployment.

Incident Overview

Quick Summary

ELongD token was exit scammed with deployer removing liquidity worth 230,455 USD from UniSwap pool in multiple transactions.

Details of the Exploit

ELongD is an ERC20 token trading on UniSwap. On Aug 8, 2021, the scammer removed liquidity from the UniSwap pool in five transactions after receiving LP tokens from the UNCX Network LP Locker Contract, where the tokens were deposited by the token deployer. The total funds lost in this exit scam amount to 230,455 USD, equivalent to 86.41 WETH.

What the Attacker Needed to Succeed

Understanding the prerequisites for this type of attack helps auditors identify protocols that are most at risk and helps developers build better defenses.

Technical Knowledge Deep understanding of rugpull and Solidity and EVM internals

Capital Required Seed capital to cover gas and initial position setup

On-Chain Access Ability to interact with smart contracts and deploy a custom exploit contract

Protocol Analysis Identification of the exploitable vulnerability in Elongate Deluxe's contract logic - root cause: token

Execution Speed Precise transaction ordering and timing to exploit the vulnerability within a single atomic block

Obfuscation Plan A strategy to launder and move stolen funds - typically through mixers, cross-chain bridges, or decentralized DEX swaps to resist tracing

What Auditors Should Check

Could this have been caught in audit? Hard to catch — private key / OpSec failures are outside smart contract audit scope

If you're auditing a protocol with similar architecture to Elongate Deluxe, these are the critical security checks that could have prevented this incident (August 2021).

Verify all logic paths related to Rugpull are guarded by proper access controls and input validation
Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
