How much was lost in the NONAME hack?

The NONAME hack resulted in $30K in losses on February 15, 2021.

What attack technique was used in the NONAME exploit?

The NONAME 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

The contract deployer used the proxy contract to mint tokens and send them onto his wallet at:

https://etherscan.io/tx/0xda6f43af…0096d4

The contract deployer added initial liquidity at:

https://etherscan.io/tx/0x03b4dcfa…5c4c20

The contract deployer removed liquidity at:

https://etherscan.io/tx/0xfce75c90…168715

The contract deployer has sold tokens at:

https://etherscan.io/tx/0x04d42088…b9fe17

In addition, the project was holding a fundraising event, using NonameCrowdsale smart contract. The list of transactions, where the sale contract gathered ETH from investors:

The raised funds had the final recipient - the proxy contract, which received ETH from the sale contract:

After, the proxy contract distributed ETH into 2 external wallets at:

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 ethereum smart contracts and deploy a custom exploit contract

Protocol Analysis Identification of the exploitable vulnerability in NONAME'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 NONAME, these are the critical security checks that could have prevented this incident (February 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
