## How Are Smart Contracts Secured against Vulnerabilities?

Security is primarily addressed through rigorous auditing by specialized firms before deployment. Formal verification methods can mathematically prove the contract's correctness.

Bug bounties incentivize white-hat hackers to find and report flaws. Despite these measures, vulnerabilities like reentrancy attacks can still occur if code is poorly written.

## Glossar

### [Smart Contract](https://learn.greeks.live/area/smart-contract/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Code ⎊ The contract is fundamentally self-executing code deployed on a distributed ledger, embodying the terms of the agreement in an immutable format.

### [Formal Verification Methods](https://learn.greeks.live/area/formal-verification-methods/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Proof ⎊ The rigorous mathematical demonstration that a piece of software, typically a smart contract, correctly implements its specified properties under all possible valid inputs, offering a higher assurance level than empirical testing alone.

### [Vulnerabilities](https://learn.greeks.live/area/vulnerabilities/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Exposure ⎊ In cryptocurrency, options trading, and financial derivatives, exposure represents the potential for adverse outcomes stemming from inherent structural weaknesses or design flaws within the underlying systems.

This composition abstractly depicts the challenge of managing staked assets within decentralized finance DeFi frameworks, specifically illustrating the bifurcation of value retention during market dislocations. The visible wear and moisture droplets on the structure suggest persistent market friction and the corrosive effect of high gas fees or sustained low-yield periods on capital deployment strategies. The opposing positions of the spheres articulate the zero-sum nature often encountered in perpetual swap contracts or synthetic asset creation where one side's profit necessitates the other's loss, challenging effective liquidation threshold management. It serves as a potent visual allegory for monitoring collateral ratios and understanding the stochastic volatility impacting option Greeks exposure in undercollateralized lending pools or complex structured products reliant on reliable external data feeds."
