Question

Here is my TransactionContext.jsx

TransactionContext.jsx:105 Uncaught (in promise) Error: No ethereum object at checkIfTransactionsExists (TransactionContext.jsx:105:13)

Error: No ethereum object at sendTransaction (TransactionContext.jsx:159:13)

I Have established an Solidity content in order to provide Ether object

Here I resolve this error by

correcting my smart_contract deploy.js

and finally there was an correction over on my contract_address
