Aptos Labs has rolled out Transaction Simulation Sessions, a new feature designed to let developers test and debug transactions as if they were executed on a live blockchain — but under complete local control.
This new system offers higher speed, simpler setup, and full compatibility with Move’s safety model, making the development process smoother than ever.
Similar to how Ethereum developers use tools like Hardhat and Foundry to fork the mainnet and test contracts with live data, Aptos developers can now enjoy the same capability — only faster, simpler, and safer.
With Transaction Simulation Sessions, real-world testing comes directly to the Aptos CLI, empowering developers to build and iterate with unprecedented efficiency.
