Subscan 2025 Q3–Q4 Funding Proposal: Operation and Maintenance Fee for Astar, Shiden and Shibuya
Approved
Previous Proposal
Overview
As the primary chain explorer and indexing service provider for Astar, Shiden and Shibuya, Subscan ensures reliable, accurate, and high-performance access to chain data for developers, validators, governance participants, ecosystem tools, and end users.
Subscan requests funding from the Astar Treasury to support 2025 Q3–Q4 operational maintenance for the following three networks:
- Astar
- Shiden
- Shibuya
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 infrastructure scaling costs.
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:
Stable bandwidth ensures explorers, wallets, and dApps receive timely responses, even during peak activity.
Monitoring & DevOps
What It Covers:
24/7 health checks, alert pipelines, CI/CD automation, system auditing, node operations, synchronization maintenance, and high availability.
Why It Matters:
These processes detect issues early (e.g., node crashes, indexer issues) and minimize service disruption.
Node Status Monitoring & Notifications
What It Covers:
Tools and alert systems to track real-time node performance.
Why It Matters:
Quick notifications help validators and ecosystem teams respond to potential issues such as forks or performance irregularities.
Technical Support & Troubleshooting
What It Covers:
Responsive assistance for users, developers, and validators with issue resolution, integration help, and guidance.
Why It Matters:
Support keeps the ecosystem running smoothly and enhances the experience for teams building dApps and tools.

- Total ASTR Required: 2,930,617 ASTR
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, partnerships)
- Incorporating community suggestions to ensure value delivery aligns with user needs
These efforts aim to improve platform utility and create sustainable monetization paths without compromising openness.
Forward Pricing Outlook (Commitments for 2026)
To address community concerns and improve predictability, Subscan commits to:
✔ Fees are expected to decrease further in 2026
Optimization tests show significant reductions in storage and bandwidth consumption.
✔ Monthly fees in 2026 will not exceed the amounts in this proposal
Even with chain data growth, Subscan commits to a strict cost ceiling.
✔ New annual / semiannual discount models under testing
- Will be released once stable
- Annual prepayment receives the highest discount tier
These commitments reinforce Subscan’s long-term alignment with ecosystem expectations.
Conclusion
Funding this proposal ensures:
- Stable and uninterrupted Astar, Shiden and Shibuya chain operations
- Reliable access to accurate historical and real-time data
- Continued support for developers, dApps, governance, and ecosystem infrastructure
We deeply appreciate the Astar community’s support.
