Solidity deployment error – ContractNotFound: No contract deployed at address

Last Updated on November 16, 2024 by sandeeppote

At time when the Ganache tool is re-opened all the Transactions and Constracts are reset. Whilst deploying contract you might see the error –

ContractNotFound: No contract deployed at {address}

PS C:\Projects\Blockchain\Solidity\brownie_fundme> brownie run .\scripts\deploy.py --network ganache-local

Solution-

Delete all the files and folders in Deployment folder as closing the Ganache tool will reset contracts etc. the deployment folder has references to old contract.
