Fix multiple timeout erros on DApp

[rohitmalhotra1420]

Timeout errors on the dApp are happening when Infura limits are crossed. Most likely we are adding a provider and then polling Infura recursively leading to this behavior. The dApp TODO comments address such possible logic where the calls are getting repeated.

There is no accurate way to reproduce since these errors usually come on localhost and only after a certain amount of hours of running the dApp.
