Subscan Funding Proposal for Hydration Operation and Maintenance Fee - 2025 Q2

---

Overview

Subscan respectfully submits this funding proposal to request support from the Hydration Treasury for operation and maintenance fees covering 2025 Q3–Q4.

As the primary chain explorer and indexing service provider for Hydration, Subscan ensures reliable, accurate, and high-performance access to chain data for developers, validators, governance participants, ecosystem tools, and end users.

We also want to express our appreciation for the feedback shared by the community. Taking your suggestions into consideration, we have updated this proposal to request funding in HOLLAR, in alignment with the community’s preference.

Service Fee Model & Pricing Methodology

Our maintenance packages are designed to support a wide range of data and operational needs, ensuring stable and efficient system performance. Because our overall cost structure is composed of multiple infrastructure and operational expenses—such as cloud services, network acceleration, monitoring systems, node providers, and the Subscan team’s ongoing operations—we use storage consumption as the primary metric for determining service fees.

Pricing Tiers

a. Basic Plan

• Up to 200 GB: $799/month
• Beyond 200 GB: $5.3/GB
• Automatically upgrades to the next tier after 350 GB

b. Advanced Plan

• Up to 500 GB: $1,699/month
• Beyond 500 GB: $5.2/GB
• Automatically upgrades to the next tier after 750 GB

c. Professional Plan

• Up to 1 TB: $2,999/month
• Beyond 1 TB: $5/GB

Monthly Service Fee Breakdown

Database Storage & Indexing

What It Covers:
Continuous indexing of on-chain data—from blocks and transactions to event logs, governance info, and NFTs—so users can reliably access both real-time and historical records.

Why It Matters:
As chain activity increases, so does data volume. By tying fees to storage needs, we accurately account for the costs of scaling infrastructure (e.g., additional database capacity).

Network Egress Bandwidth

What It Covers:
The outgoing traffic required to serve user requests quickly and consistently, including API calls, UI data retrieval, and integrations with third-party tools.

Why It Matters:
A stable, high-bandwidth connection ensures that explorers, wallets, and dApps receive timely data responses, even during peak activity.

Monitoring & DevOps

What It Covers:
Round-the-clock health checks, internal alert pipelines, CI/CD automation, and system auditing. This includes running multiple nodes, maintaining synchronization, and ensuring high availability.

Why It Matters:
These processes help detect issues early (e.g., node crashes, indexer slowdowns) and streamline updates or deployments, minimizing service disruption for the community.

Node Status Monitoring & Notifications

What It Covers:
Dedicated tools and alert mechanisms to track the real-time status of network nodes.

Why It Matters:
Quick notifications enable parachain teams, validators, and the wider ecosystem to react rapidly to performance changes, forks, or potential security incidents.

Technical Support & Troubleshooting

What It Covers:
Responsive assistance for users, developers, and validators, including issue resolution, feature guidance, and integration help.

Why It Matters:
Timely support keeps the ecosystem running smoothly and fosters a positive development environment—especially crucial for teams building dApps, explorers, and automation tools.

Long-Term Sustainability & Vision

Our long-term goal is to reduce reliance on treasury funding through multiple channels:

• Continuous optimization to limit infrastructure costs as chain data grows.
• Exploring responsible revenue streams (e.g., optional premium features or partnerships).
• Actively incorporating community suggestions to ensure value delivery aligns with user needs, increasing platform utility and potential monetization avenues without compromising openness or neutrality.

Forward Pricing Outlook (Commitments for 2026)

We acknowledge ongoing community concerns regarding long-term cost control.
To provide clarity and predictability, Subscan makes the following commitments:

✔ Fees are expected to decrease further in 2026

Infrastructure optimization efforts are underway, and test results have shown significant reductions in storage and bandwidth costs.

✔ Monthly fees in 2026 will not exceed the amount proposed in this proposal

Even if on-chain data grows substantially, Subscan commits to a strict cost ceiling for 2026.

✔ New annual / semiannual discount mechanisms are in internal testing

• These models will be publicly released once stabilized.
• Annual prepayment will always receive the highest discount tier.

These commitments aim to improve transparency and reinforce Subscan’s long-term alignment with the community’s expectations.

Conclusion

Funding this proposal ensures:

• stable and uninterrupted Hydration chain operations,
• reliable access to accurate historical and real-time data,
• continued support for developers, dApps, governance, and ecosystem infrastructure.

We deeply appreciate the Hydration community’s continued trust and support.
