  2. For improved granularity, 1 CU has been updated to 100 CU.
  3. Announcing our new "Basic" plan priced at $19.99.
  4. CUs are now denominated in CUC and are refreshed daily. Monitor your balance at
  5. With our updated plans, extra CUCs beyond those plans allow you to access extra API calls using a pay-as-you-go system every day. is committed to providing cost-effective and efficient solutions to DeFi, wallet, and analytics developers. Our customer feedback revealed a few key insights:

  1. A requirement for an intermediate tier between the Free and Pro plans.
  2. A desire for a more flexible 'pay-as-you-go' option.
  3. An opportunity for us to accommodate more requests through a more efficient infrastructure.

Based on these insights, we're excited to announce the introduction of a pay-as-you-go feature using Compute Unit Credit (CUC), and to share details about modifications to our pricing plans.

Understanding Compute Units and Compute Unit Credit

A Compute Unit (CU) serves as a standard measurement that quantifies the computational expense incurred during an API call. It's akin to how AWS charges for compute usage. The computational cost varies depending on the intensity of the queries – some are lightweight and fast (e.g., eth_blockNumber) while others can be more demanding (e.g., large eth_getLogs queries). The cost in CU for each request across different products can be found in our API marketplace.

Compute Unit Credits (CUC) are like credit card rewards on our platform to serve as royalty points. Those points are identical to compute units. Developers could spend CUC on our platform to get extra quotas for API calls.

Implementing Pay-As-You-Go with CUC

We'll set up a reward account for each customer. Customers can load this account with CUC, which will then be consumed as per their API usage.

  • For the Free tier, we ensure a minimum balance of 0.3 CUC at the start of each month.
  • For the paid tiers (Basic, Pro, Enterprise 50), we will credit the account on each subscription or renewal.

We do not allow customer to withdraw CUC for now.

The credits on will be reconciled daily and also each time a withdrawal or deposit is made. maintains the rights to the Compute Units (CU) on our platform, along with the authority to clarify the application of the API and the usage of credits.

Pricing Plan Modifications

Below are the changes to our pricing plans. The original pricing structure was as follows:

DApp developers and businesses often struggle to find reliable and easy-to-use node infrastructure on blockchains, which can hinder the development and deployment of their applications.

By adding more EVM-compatible blockchains to our suite of services, ChainPlus API is providing developers and businesses with a simple and easy-to-access service that offers the best node infrastructure on blockchains. Those blockchains are Ethereum, IoTeX, Filecoin, Harmony, BSC, Arbitrum, Arbitrum Nova, Optimism, Gnosis and EthStorage Galileo Testnet.

Dora Noda, cofounder of, commented, "we are excited to expand our suite of services by adding more EVM-compatible blockchains to ChainPlus API. This will provide our customers with even more options for node infrastructure and enhance their blockchain development experience."

Nathan Pang, Blockchain Explorer developer at Blockroma, says "we started to use with its Aptos APIs. Now, with the addition of more EVM-compatible blockchains, ChainPlus API has made it easier for us to build and deploy our blockchain applications. The improved node infrastructure has saved us time and effort, allowing us to focus on developing innovative solutions."

Why is adding those 8 EVM blockchains?

We attended ETH Denver, one of the largest Ethereum hackathons in the world. As we walked around the event, we were amazed by the sheer creativity and innovation that was on display. From decentralized finance apps to gaming platforms, the possibilities seemed endless.

But what really struck us was the sense of community and collaboration that permeated the entire event. Developers from all over the world were working together to build new tools and applications that could potentially revolutionize entire industries.

Then we realized just how important the Ethereum ecosystem was becoming, and we knew that this company needed to be a part of it. We made the decision then and there to add Ethereum to its Aptos and Sui API suite, allowing developers to easily integrate Ethereum-based applications into their own projects. at EthDenver

Thanks to our visit to ETH Denver, we were able to see firsthand the power of the Ethereum ecosystem and the potential it had to transform the tech industry. And by adding it to our company's offerings, we were helping to ensure that his own developers would be able to take advantage of all that Ethereum had to offer. Presenting at EthDenver's Mission
