Incident Overview

The Friendsies NFT collection has been rug pulled by its founders, less than a year after raising $5 million at a Christie's auction on OpenSea, due to market volatility and challenges.

The founders of Friendsies announced on Twitter that they were pulling the rug on the project, blaming the current market conditions for preventing them from developing the project in a way they could be proud of. The project had been criticized by community members for deviating from its initial roadmap, with several aspects remaining undelivered, including a community treasury and a play-to-earn game. On-chain sleuth ZackXBT also revealed that the project's founders had not distributed 1.25% of all royalties to holders, as claimed in the project's official Discord server.

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 Friendsies's contract logic - root cause: nft
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 Friendsies, these are the critical security checks that could have prevented this incident (February 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
