How much was lost in the Friendchips.tech hack?

The Friendchips.tech hack resulted in $39K in losses on September 15, 2023.

What attack technique was used in the Friendchips.tech exploit?

The Friendchips.tech 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

Friendchips.tech was rugpulled, the deployer dumping tokens which worth 77,383 $USD

Details of the Exploit

FRIENDCHIPS is an ERC20 token trading on UniSwap. The deployer had previously added liquidity in the amount of 24 WETH. Subsequently, a malicious contract was created to mint tokens and dump them, resulting in a theft fof 39,276 $USD equivalent to 23.94 WETH.

The stolen funds were then withdrawn by the deployer using TornadoCash to obfuscate the transaction trail.

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 Friendchips.tech'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 Friendchips.tech, these are the critical security checks that could have prevented this incident (September 2023).

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
