Levana Geoblocked Request is not cached locally [200 USDC Reward!]

🐛 Bug Bounty: Tree Shaking Optimization Needed! 🛠️
Reward: 🏆 200 USDC 🏆

We are thrilled to announce a special bug bounty for proficient third-party developers! This is an opportunity to showcase your expertise, make a significant impact, and earn a substantial reward.

Issue Description 📄
Cache Levana Geoblocking Request

Current Behavior ❌
Try refreshing the frontend a few times with the cache enabled. You will see that the levana geoblocked request is not cached, and is remade on every request. This should ideally hit a local cache for the same input country code if you are coming from the same IP.

Expected Behavior 💡
On page refresh from the same IP address, the levana geoblocking request should not be rerun but instead be fetched from the cache

I'm not sure if this can be really implemented. How would the browser know the current IP? To go by location, you'd need to ask for location permissions, but that is based on the user's consent only.

@UkuLoskit you could use something like https://api.ipify.org?format=json to get it, but this essentially would mean you have to make that call on every page load instead of the call to Levana. It would only be worth it if the call to https://api.ipify.org?format=json was substantially faster than the call to Levana.

@UkuLoskit how about this, could you run some benchmarking between https://api.ipify.org?format=json and the levana geoblock call? If you can demonstrate that it would not result in a speed increase to make the change, I'll still pay the bounty

Very simple benchmark:

for i in $(seq 1 10); do curl -o /dev/null -s -w 'Total: %{time_total}s\n' "https://geoblocked.levana.finance/"; done
Total: 0.222422s
Total: 0.284780s

for i in $(seq 1 10); do curl -o /dev/null -s -w 'Total: %{time_total}s\n' "https://api.ipify.org?format=json"; done 
Total: 0.252997s
Total: 0.225216s

I intentionally did not use something like wrk or ab, so as to replicate making a request to new connection on initial page load (TCP handshake, no keepalive).

The results are comparable (geoblock is slightly faster), so there is not time to be saved by making this extra request.

@UkuLoskit I missed this. Thanks for doing the research. If you message finance@osmosis.team they can help with the bounty
