Because smart contracts are immutable once deployed to public or consortium blockchains, security flaws cannot be patched with simple hotfixes without introducing sophisticated proxy architectures. Ensuring code correctness prior to deployment is paramount.

1. Common Pitfalls and Mitigation Strategies

  • Checks-Effects-Interactions: Always update internal state balances before issuing external token transfers or low-level calls to eliminate reentrancy attack vectors.
  • Strict Role-Based Access Control (RBAC): Use OpenZeppelin AccessControl with time-locked multi-signature multisig accounts rather than single private keys.
