What attack technique was used in the THORChain exploit?

The specific attack technique used in the THORChain hack has not been formally classified. Review available post-mortems and on-chain data for technical details.

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.

What Auditors Should Check

Audited by Audit Report 1 — still lost $10.7M. Prior audits don't guarantee safety, especially after post-audit code changes.

If you're auditing a protocol with similar architecture to THORChain, these are the critical security checks that could have prevented this incident (May 2026).

Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
