- Experts recommend stricter security like timelocks and hardcoded supply caps.
UXLink Hack Exposes the Dangers of Fake Decentralization
The UXLink Hack Exposes a troubling reality in many so-called decentralized platforms: centralized control still exists behind the scenes.
Despite branding itself as a decentralized social crypto project, UXLink suffered a major breach through its multisignature wallet.
Attackers exploited a delegate call vulnerability, took full control of the smart contract, and minted billions of tokens, tanking UXLINK’s price from $0.33 to just $0.033.
While Cyvers Alerts estimated losses at around $11 million, Hacken believes over $30 million worth of tokens were stolen.
This breach forced UXLink to deploy a new Ethereum smart contract, this time without a mint-burn function, in an effort to restore trust and stop further abuse.
UXLink Hack Exposes Smart Contract Security Gaps
Cybersecurity experts say the UXLink Hack Exposes how critical it is to integrate proper safeguards early in a project’s development.
Marwan Hachem, CEO of Web3 security firm FearsOff, explained that the exploit happened because of poorly implemented controls in the multisig wallet.
According to Hachem, the breach occurred due to:
- An unprotected delegate call in the wallet
- No minting restrictions in the contract
- Absence of a hardcoded supply cap
“These are basic crypto security flaws,” said Hachem in a Cointelegraph interview. “And they were entirely preventable.”
Simple Fixes That Could Have Stopped the Hack
To prevent similar exploits, Hachem suggested a few standard practices every crypto project should follow:
- Timelocks for critical actions: Delaying contract changes gives the community time to spot suspicious activity.
- Renouncing minting rights: Once a token is launched, no one should have permission to create more.
- Hardcoded supply caps: This ensures no excess tokens can ever be minted, regardless of control.
Transparency and safety in any serious crypto project are required for technical reforms, ongoing audit, public wallet addresses and multi-comprehensive requirements.
Multisig wallets are not infallible
Although multisig wallets are widely seen as a secure option in crypto, Hachem warned they are only as strong as their implementation.
In UXLink’s case, the exploit highlights how over-reliance on multisigs without auditing can lead to catastrophic results.
He also advocated for:
- Emergency stop mechanisms in smart contracts
- Community-governed access to sensitive functions
A culture of security-first development, rather than rushing to launch
