Real-Time (WSS)
Real-time delivery over WebSockets (WSS) is priced flat — not CU-based. We currently offer a custom plan only. Low-latency delivery is a core strength of BlockDB, and we support it efficiently via WebSockets (WSS) including Protobuf. Capacity and pricing are tailored to your stream volume rather than fixed tiers.Discuss WSS access
Contact us with your stream requirements and we’ll put together a flat-rate plan.
Bulk Export (SFTP, S3, Azure & more)
Full historical data is available both through the API (CU-based) and via direct bulk delivery. For large backfills or ongoing dataset syncs, bulk delivery is significantly cheaper than querying through the API — you pay for the dataset and delivery method, not per-row CU costs. Pricing is customized for each customer.Pricing Factors
- Datasets: Which datasets you need (blocks, transactions, logs, pricing, etc.)
- Chains: Number of blockchain networks (Ethereum, Polygon, Arbitrum, Base, etc.)
- Delivery Method: SFTP, S3, Azure Blob Storage, Snowflake Share, Redshift Share, BigQuery, or Databricks Delta Share
- Delivery Frequency: One-time export, daily, weekly, or monthly snapshots
- Data Volume: Historical depth and time range requirements
Each bulk delivery configuration is unique. We work with you to design a solution that matches your data requirements, budget, and infrastructure preferences.
