Updates to the ZAN Node Service Credits Pricing Model and Plans

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：

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.

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.
