Smart Contract Security: Common
Vulnerabilities

2024 audits. We'll look at reentrancy
attacks, integer overflows, and access
control failures—then refactor vulnerable
code together. Bring questions about your own
contracts if you're working on something.

Decentralized Storage Patterns with IPFS
When should you store data on-chain versus
IPFS? Elara compares approaches for different
use cases, shows how to pin content reliably,
and demonstrates integration with smart
contracts. We'll also troubleshoot common
issues with content addressing and gateway
