TL;DR
Reentrancy, oracle manipulation, logic bugs, and why a clean audit is not a guarantee.
In one block
Smart-contract risk is the possibility that deployed code, its dependencies, or its governance behaves differently from what users expect. Contracts compose token logic, price inputs, permissions, upgrades, and external calls; an attacker looks for mismatched assumptions across those boundaries.

Smart-contract risk is the possibility that deployed code, its dependencies, or its governance behaves differently from what users expect.
The useful way to understand smart-contract risk is to separate the underlying system from the apps and services built around it. The system follows technical rules; a service may add custody, recovery, fees, limits, or human support on top.
That distinction matters because two products can use the same network while exposing users to very different operational and security trade-offs.

A wallet prepares an instruction, the user or an authorised policy signs it, and the relevant network or service validates that instruction against its rules. A successful interface message is not the same as final settlement.
Fees, confirmation time, and reversibility depend on the network and product. Always verify the asset, address, chain, amount, and contract interaction before signing.
Risks and failure modes
Quick answer
Audits sample code and assumptions at a point in time. New deployments, governance changes, economic attacks, and unknown bugs remain possible.

The biggest losses usually come from a combination of technical complexity and rushed human decisions: copied addresses, malicious approvals, weak account recovery, fake support, or concentration in a single provider.
Risk cannot be eliminated, but it can be made visible. Prefer small test transactions, independent verification, strong authentication, and a written recovery plan.
A practical smart-contract risk checklist
Quick answer
Review audit scope, deployment address, admin powers, oracle design, upgrade delay, bug bounty, incident history, and value concentration.
Review audit scope, deployment address, admin powers, oracle design, upgrade delay, bug bounty, incident history, and value concentration.
Document the network, wallet, recovery method, trusted contacts, and any service that can move or freeze funds. Review permissions regularly and remove access that is no longer needed.
Keep operational funds separate from long-term holdings. The simplest secure setup is the one you can test, explain, and recover without improvising under pressure.
