Short description: Ongoing &amp; advanced costs for the running of high performance, scalable, and reliable public infrastructure in Q1 and Q2 of 2025 for Polkadex Solochain.
Why are Public RPC Services Needed for Polkadex Setting up blockchain infrastructure is difficult, time consuming, and expensive:
It requires a level of server development expertise that many do not have It&rsquo;s costly to run a full node nearly continuously, especially when your dApp&rsquo;s traffic is low and inconsistent. Running production level infrastructure is especially tricky. You need to autoscale quickly to handle bursty traffic, and you want to provide services in different regions around the world to provide low latency services - all of this is incredibly costly, but comes with significant economies of scale for a provider. DevOps requires constant attention - time that would be better spent elsewhere building. A shared node API service helps mitigate these barriers of entry to trying accessing a new protocol by reducing all these costs to near zero. We manage all the nodes for our users and distribute them across the world (with intelligent routing) to achieve global scalability from day 1, we monitor each node and ensure that they meet certain service levels, and we have the expertise and scale to handle production workloads and high peak traffic. In summary, we try to reduce the pain of getting started on Polkadex and minimise the costs of accessing secure nodes while traffic from your dApp is low. When you grow, you can continue to use our shared API service, or we also provide access to one click deploy dedicated polkadex nodes to any cloud of your choosing.
OnFinality&rsquo;s RPC Service As Polkadot&rsquo;s largest and most cost efficient infrastructure provider, this proposal will support OnFinality&rsquo;s free public API services for the Polkadex community.
Since our inception in November 2020 we have a long track record focussing on three key areas; performance/reliability, providing more value from our Ultimate API service, and cost optimisation.
Performance/Reliability In 2024, we upgraded our Polkadex endpoints to multi-region setups - Hong Kong and North Virginia. OnFinality now provides the lowest global latency RPC endpoint for Polkadex.
We are the only RPC provider to guarantee 99.9% uptime with actual financial penalties (see appendix A). We proudly display and share our 90 day uptime statistics for each network publicly here.
Cost Optimisation &amp; Decentralisation OnFinality is very conscious about providing a strong level of support for Polkadex at an extremely competitive price. That&rsquo;s why our Polkadex API services are running entirely on OnFinality Cloud, our own private hardware and self service Cloud.
Service Details In the last 6 months (2024-06-01 and 2024-12-31) our Polkadex API service has:
Served a total of 6 Billion (6,252,401,537) responses Accumulated over 2,300 GB of data egress The highest daily total was 52 million responses in a single 24 hour period Our rolling 7 day average at the end of this period was over 33 million responses each day All time totals for Polkadex is 11.4 Billion (11,428,022,261) since March, 2022 At the end of this period the 90 day uptime for Polkadex was 99.9%. Costing We are using a fixed price to allow us to bill in advance and to simplify the administration of this proposal, as well as provide cost clarity to both parties. This proposal includes combined running costs for our infrastructure for Polkadex for all of Q1 and Q2 2025. By paying 6 months up-front we will apply a 15% discount to our services.
The total combined running cost is USD $7,599.00 after discounts. This is all inclusive of capital and operating expenses, administration time from OnFinality DevOps, onboarding costs, backup costs, and all other monitoring and right-sizing by our team. The base price change from the previous period is due to larger compute resources required to serve the increased requests.
