**Date:** 20/03/2023

**Requested allocation:** USD $12,000

**Proposal Summary:** Provide free RPC service for the Polkadex community in 2023 and early 2024 to encourage growth and development.

### **Project Summary**

RockX currently provides free APIs on Polkadot and Kusama up to 100,000 requests per day. However, we would like to accelerate the ecosystem’s growth by expanding our offering to include free packages for more parachains.

With Polkadex's support, in addition, to help from the Polkadot Treasury, RockX will set up and run an RPC node on the Polkadex chain offering it for free to all developers and node users up to 100,000 requests per day per user. In addition to free API requests, RockX also provides a developer-friendly portal that allows users to set up APIs across all supported chains with just a few clicks, reducing the complexity and set-up time drastically. Last but not least, developers can also subscribe to our blockchain maintenance dashboard so that they will be able to receive the latest blockchain update information about Polkadot and its ecosystem.

To support the development of the Polkadex ecosystem, RockX will be offering free plans for developers that include 100K requests per day (or 3 million requests per month). This will be sufficient for most developers and users. Developers can access this free API service by creating their own API Key on the RockX portal and using the provided tools to optimize their development efforts. Up to 10 API keys can be generated for free for each blockchain. If any customization is needed, RockX can also assist with setting up custom archive nodes or full nodes. Every quarter, RockX strives to improve and enhance our product offerings and infrastructure for developers in the Polkadot ecosystem, including front-end UI, connectivity, security, and reliability. New product releases can be found on RockX’s Twitter page.

In summary, we’re here to take on all the complexities of node operations and utilize economies of scale and scope to lower the developers’ barriers (time and money) to adoption.

### **History & Reliability**

RockX has been providing RPCs for Polkadot and Kusama since Oct 2021 and has achieved service reliability of 99.9% for Q4 2022 ([Link](https://access.rockx.com/product/polkadot-blockchain-api-for-web3-builders)).

The duplicate Polkadot nodes setup and the automatic failover system ensure the stability of the Polkadot node. In case of a node failure incident or during the Polkadot mainnet upgrade period, the automatic failover system directs users' requests to a backup node, ensuring continuous network operation.
