## [March 26, 2026] Notice on the Upgrade of ZAN Node Service Credits Pricing Model and Plan Adjustments Dear Users, Thank you for your continued trust and support in ZAN Node Service. To better align node performance and resource consumption across different business scenarios, and to improve the transparency and predictability of our billing rules, the ZAN team has decided to comprehensively upgrade the existing Credits pricing model and optimize the plan structure accordingly. This adjustment is based on mainstream market standards and our actual operational data, with the aim of making the resource pricing of different API methods more reasonable and consistent. The details of this upgrade are as follows: ### I. Core Adjustments #### 1. Credits Pricing Model Optimization We have re-evaluated the resource consumption weights of various API methods and updated the billing rules accordingly. Example Reference： | Chain Ecosystem | Method | Original Credits | New Credits | Change | | --------------- | ------------------------ | ---------------- | ----------- | ------------ | | Ethereum | eth_call | 40 | 20 ⬇️ | -50% | | Ethereum | eth_chainId | 0 | 20 ⬆️ | Newly priced | | Ethereum | eth_blockNumber | 10 | 20 ⬆️ | +100% | | Ethereum | eth_getLogs | 75 | 20 ⬇️ | -73% | | Ethereum | eth_getFilterLogs | 75 | 20 ⬇️ | -73% | | Ethereum | debug_traceTransaction | 80 | 40 ⬇️ | -50% | | Ethereum | debug_traceBlockByNumber | 500 | 40 ⬇️ | -92% | | Ethereum | debug_traceBlockByHash | 500 | 40 ⬇️ | -92% | | Solana | getBlock | 100 | 30 ⬇️ | -70% | | Solana | getBlockHeight | 10 | 30 ⬆️ | +200% | | Solana | getFirstAvailableBlock | 60 | 30 ⬇️ | -50% | | Solana | sendTransaction | 50 | 30 ⬇️ | -40% | **Adjustment Direction:** The Credits consumption for some high-frequency, lightweight methods — such as `eth_call` and `eth_getLogs` on certain chains including Ethereum — will be reduced. The Credits consumption for some high-load or ecosystem-specific methods — such as `eth_blockNumber` in the Ethereum ecosystem and `getBlockHeight` in the Solana ecosystem — will be moderately increased. For the latest Credits consumption standards for each API method, please refer to the Resource Pricing Documentation, which will be updated upon the official launch. #### 2. Plan Quota Updates In line with the new billing rules, we will also adjust the total Credits quotas included in each subscription tier (Free / Growth / Pro) to ensure that the overall value of each plan remains reasonable and transparent under different usage patterns. For most developers, the overall cost is expected to remain relatively stable, although the actual impact will depend on usage volume and API call distribution. | Plan | Original Quota | New Quota | Original Add-on Price | New Add-on Price | | ------ | -------------- | --------- | --------------------- | ---------------- | | Free | 300M | 150M | / | / | | Growth | 500M | 330M | $0.2/M | $0.15/M | | Pro | 3B | 2.3B | $0.2/M | $0.13/M | #### 3. Effective Date **April 10, 2026, at 00:00:00 (UTC+8)** ### II. Impact Assessment by Business Scenario Based on the primary ecosystems and usage patterns, the expected cost trend is as follows: * 📉 Costs may decrease: Users primarily operating on ecosystems such as BSC / Base / Arbitrum, and frequently using methods like `eth_call` or `eth_getLogs`. * ➖ Costs may remain largely unchanged: Users mainly operating on ecosystems such as Solana / Polygon / Optimism, with relatively balanced API method usage. * 📈 Costs may increase: Users in scenarios such as wallets and exchanges on ecosystems like Ethereum / Sui, especially those heavily relying on methods such as `eth_getTransactionReceipt`, `eth_blockNumber`, and `eth_chainId`. **💡 Recommendation:** If your application involves multi-chain mixed calls, we recommend reviewing your call logs in advance and optimizing your request strategy to better control costs. ### III. Transition Period and Implementation Plan **🛡️ Protection Period for Existing Paid Subscribers:** Users who subscribe to the **Growth** or **Pro** plan before **April 10, 2026** may continue using the original pricing and quotas until **April 10, 2027, 00:00:00 (UTC+8)**. They may also choose to switch to the new pricing model starting from the next service cycle if it is more favorable. Please do not cancel your subscription during this period, as any new subscription will be charged under the new pricing model. **⚠️ New Users / Plan Changes:** Starting from the effective date, all new subscriptions, plan changes, and re-orders will be subject to the new pricing standard. **📊 Enterprise Customers:** Customers under a signed Enterprise agreement will not be affected by this adjustment. If necessary, please contact our sales team for a renewed evaluation and quotation. ### IV. Frequently Asked Questions **Q: Will this adjustment affect service stability or throughput?** **A:** No. This change only affects billing logic (Credits consumption) and plan quotas. Node performance, TPS limits, and service stability will remain unchanged. **Q: I am currently on the Growth plan. If I upgrade to Pro, which pricing will apply?** **A:** The new pricing standard will apply. Starting from April 10, 2026, any plan modification — including manual upgrades, downgrades, or repurchases of the same plan after a failed renewal — will be treated as a new order and will directly follow the latest Credits pricing model and quota structure. **Recommendation:** If you wish to retain the old pricing, please carefully evaluate your usage cost before upgrading, or keep your current plan until the end of the protection period on April 10, 2027. **Q: Where can I view the detailed API pricing table?** **A:** Please visit our Resource Pricing Documentation for the latest details.

Our team has worked tirelessly to optimize our product offerings and enhance the user experience. We have introduced several new subscription plans for developers to choose from, including a Free plan for Web3 beginners, a Growth plan for individual developers, a Pro plan for professional teams, and a Custom plan designed for large-scale enterprise applications. The Custom plan offers customized options for all subscription specifications, enabling you to select the plan that best fits your development needs. For the latest pricing information for ZAN Node, please refer to the official release documentation. ### Impact Users who participated in the public beta will no longer have access to the Free Beta Testing plan, which will be invalidated and cleared. Instead, each user will be automatically issued the Free plan. New users who join ZAN Node at UTC+8, 0:00 on August 1, 2023, will automatically receive the Free plan upon registration. Please note that you can pay to upgrade to other plans, and if you have purchased a paid plan, we will continue to issue the Free plan on a monthly basis after the plan expires.

The rate limits for the Free plan will be lower than the Free Beta Testing plan, specifically decreasing from 700 credits/s to 300 credits/s. Monthly credits will also decrease to 300 million. Please be aware of how this may affect your usage. The Growth plan offers the same credit usage and rate limits as the Free Beta Testing plan.

### Event notice We will be inviting users who participated in the public beta to complete a questionnaire via email. This will be an opportunity for you to report any bugs or suggest optimizations that could help us improve our products. Additionally, we will randomly select 10 users who provide valid feedback and reward them with a free one-month ZAN node service enhanced version (Growth plan). Please ensure that you check the official email address that you registered and trust to avoid missing the invitation to participate in the questionnaire. Thank you for your support!
