What's the biggest rug risk on Ethereum?

Proxy-upgradeable contracts are the most dangerous pattern unique to Ethereum — devs can replace the entire token logic post-launch, introducing fees, blacklists, or mint functions that didn't exist at audit time. Always check proxy implementation address on Etherscan before sizing.

How do I detect a honeypot on Ethereum?

A honeypot blocks selling while allowing buying. Sharpe's Rug Check runs a simulated sell transaction to detect this pre-trade. If simulation fails or returns unexpected tax, the token is flagged as a honeypot or tax-token.

Tokens with coded buy or sell fees that redirect a percentage of each trade to a dev wallet, burn address, or liquidity pool. Legitimate tax tokens disclose fees (1–5%); malicious ones hide 50–99% sell taxes. Sharpe simulates both directions to detect hidden fees.

Is renounceOwnership() enough?

Not always. For simple ERC-20 contracts, ownership renunciation eliminates most admin-function risks. For proxy contracts, renouncing the proxy owner doesn't affect the implementation — devs can still control via upgrade authority. Always verify both.
