## What Are the Risks Associated with Flash Loan Arbitrage?

The primary risks associated with flash loan arbitrage are smart contract vulnerabilities, network congestion, and front-running. Smart contract vulnerabilities can be exploited by malicious actors to drain funds from a contract.

Network congestion can lead to high gas fees and delayed transaction times, which can eliminate arbitrage profits. Front-running occurs when a malicious actor sees a profitable transaction in the mempool and pays a higher gas fee to have their own transaction executed first, effectively stealing the arbitrage opportunity.

Additionally, flash loan arbitrage is a highly competitive field, and there is no guarantee of success.

## 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.

### [Decentralized Oracles](https://learn.greeks.live/area/decentralized-oracles/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Attestation ⎊ Decentralized oracles, within cryptocurrency and derivatives, represent a pivotal shift in data sourcing, moving away from centralized authorities to verifiable, distributed networks.

### [Flash Loan Arbitrage](https://learn.greeks.live/area/flash-loan-arbitrage/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Mechanism ⎊ Flash loan arbitrage exploits temporary pricing discrepancies across decentralized exchanges (DEXs) within the cryptocurrency ecosystem, leveraging the ability to borrow unsecured assets.

### [Flash Loan](https://learn.greeks.live/area/flash-loan/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Mechanism ⎊ A flash loan represents an uncollateralized loan executed entirely within a single blockchain transaction, enabling borrowers to access substantial capital for a very short duration, typically seconds.

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

Exploitation ⎊ Smart contract vulnerabilities represent systemic risks within decentralized finance, impacting the integrity of financial instruments and the reliability of automated execution.

### [Network Congestion](https://learn.greeks.live/area/network-congestion/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Latency ⎊ Network congestion within cryptocurrency, options trading, and financial derivatives manifests as increased latency, directly impacting execution speeds and potentially leading to adverse selection against slower participants.
