Overview

As the primary chain explorer and indexing service provider for Bifrost & Bifrost Kusama, 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 Bifrost Treasury to support 2025 Q3–Q4 operational maintenance for the following networks:

Service Fee Model & Pricing Methodology

Our maintenance packages are designed to support a wide range of data and operational needs, ensuring stable and efficient performance. Because our overall cost structure includes cloud services, network acceleration, monitoring, node providers, and Subscan team operations, we use storage consumption as the primary metric for determining service fees.

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

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
• Exploration of responsible revenue streams (premium features, partnerships, etc.)
• Community-driven improvements to maximize value delivery

---

Forward Pricing Outlook (Commitments for 2026)

To provide stability and predictability, Subscan commits to:

✔ Fees are expected to decrease further in 2026

Ongoing optimization shows significant reductions in storage and bandwidth.

✔ Monthly fees in 2026 will not exceed the amounts proposed in this request

A strict cost ceiling is guaranteed even with chain growth.

✔ New annual / semiannual discount mechanisms are under testing

• Will be published once stable
• Annual prepayment receives the highest discount tier

These commitments strengthen Subscan’s alignment with long-term community expectations.

Funding this proposal ensures:

• Stable, uninterrupted Bifrost and Bifrost Kusama operations
• Reliable access to accurate historical and real-time chain data
