On-Chain Security

These terms describe common security patterns and attack surfaces without making any investment recommendations.

Multisig

A multisig wallet requires approvals from multiple keys to execute actions, reducing single-key compromise risk.

A reentrancy bug can let an attacker call into a contract again before state updates, potentially draining funds if not protected.

Oracle manipulation is when an attacker influences the data a protocol trusts (often prices), causing incorrect accounting or liquidations.

A smart contract audit is a structured security review that looks for bugs, unsafe assumptions, and potential exploits before deployment.
