Transaction Simulation
Definition
The process of running a blockchain transaction in a virtual environment (before it is actually executed onchain) in order to predict its outcome, allowing users to see if there are any issues or unintended consequences beforehand.
Description
Transaction simulation is a valuable tool in blockchain ecosystems, where users interact with complex smart contracts.
By simulating the transaction first, they allows users to check for potential errors or attacks, such as sending tokens to the wrong address or falling victim to a wallet drainer.
Simulations also help users avoid unexpected gas fees or contract bugs that could result in loss of funds. By previewing the outcome, users can make more informed decisions about whether or not to proceed with the transaction.
