## Smart Contract Pre-Checks

Smart contract pre-checks are logic-based tests performed within a transaction before executing the main function. These checks ensure that the conditions required for a successful trade are met.

For example, a pre-check might verify that the expected price of an asset is still within a certain range before proceeding with a swap. If the check fails, the transaction reverts, protecting the user from an unfavorable outcome.

This is a critical security and risk management feature for any automated trading bot. By including pre-checks, traders can prevent losses caused by rapid market shifts or other unforeseen events.

It adds a layer of safety to the inherently risky environment of decentralized finance. The design of these checks requires careful consideration of the trade's objectives and the potential failure modes.

They are an essential component of robust smart contract development.
