- Assess if the frequency is needed
- Reduce frequency and ideally cut down infura calls by x2

### Threat Modeling Framework

_No response_

### Acceptance Criteria

_No response_

### References

Start by tracing the Wallet View's Infura requests while the mobile client is open and idle, then identify the root trigger and measure the request frequency. Assess whether the current frequency is necessary and verify that the change reduces Infura calls, ideally by half.
