# Crypto APIs Simulate

> Use this tool when you need to predict the outcomes of EVM transactions before committing them on-chain, helping to identify potential failures and estimate gas costs. It simulates transactions in a dry-run environment, allowing for validation of transaction parameters and optimization of on-chain interactions. Ideal for developers and users who want to test and refine their transactions before execution, reducing the risk of errors and unnecessary costs.
