Most people think smart contract risks are simple. This is what really matters:
Common types of attacks include reentrancy, oracle manipulation, access control errors, and cross-chain bridge verification flaws.
Contracts that have been running for a long time and have been tested with large amounts of funds are generally considered more reliable, but that doesn't mean they have no vulnerabilities.
Revoke token approvals for protocols you no longer use.
Ethereum, where $ETH is located, was one of the earliest public blockchains to support general-purpose smart contracts.

I could be wrong, too. Don't just follow what I say.
