Interact with InstaDApp DSA using Forked Mainnet from your local network Interact with InstaDApp DSA using Forked Mainnet from your local network
When you want to interact with contracts that are deployed on the Ethereum mainnet for development purpose without spending any ether you can fork the mainnet from a particular block number and then interact with that forked mainnet on your local machine.

This may take few minutes as ganache has to fetch contracts from mainnet and then work on them so be patient, if you want to know if it has stuck or not then head to the tab on console where the ganache-cli is working and check if it is making some calls.

If you want to use any particular token then you can unlock address which holds that token and you can get list of all token holders on
ethplorer. If you want to use any particular token then you can unlock address which holds that token and you can get list of all token holders on ethplorer.
If you encounter error saying : “Error: Returned error: Returned error: project ID does not have access to archive state”. Trying reloading the ganache-cli as this will most probably fix this.

**Note:** This is not the best way to interact with DSA as you might face a lot of errors in the process of interacting on forked mainnet. The best way is still the Ethereum Mainnet. **Note:** This is not the best way to interact with DSA as you might face a lot of errors in the process of interacting on forked mainnet.
