Archival Data

Tatum Gateway Overview

The Tatum Gateway simplifies blockchain connectivity while ensuring maximum efficiency and reliability. Powered by an advanced balancing engine, it intelligently routes every RPC request to the most optimal endpoint based on real-time performance, data freshness, and endpoint health — delivering consistently accurate and up-to-date blockchain responses.

• Lower latency with consistently faster response times
• Guaranteed data accuracy, eliminating mismatches and stale responses
• Enhanced reliability and security through proactive request handling and endpoint isolation
• Stable performance even during traffic spikes and network volatility
• Zero configuration optimisation powered by automated PowerUps

Node Data History

While Tatum endeavours to maintain complete blockchain history from genesis for all supported chains, this is not always feasible. The blockchains listed below currently have limited historical data availability.

Mainnets

• Algorand – Performance degradation occurs when querying blocks older than ~19,000,000 (approximately February 2022 and earlier). Requests in this archival range may exceed 60 seconds or time out due to limitations in thealgorand-mainnet-indexer archive indexing. We are evaluating alternative providers for improved historical access, but currently cannot guarantee performance for deep archive queries.
• Arbitrum one - Two empty blocks are missing between Nitro and Classic (22.207.816 and 22.207.817).
• EOS - Historical data is available starting from block 254,699,235.
• HAQQ - Only the most recent ~60 days of historical data is available.
• NEAR - Some blocks were skipped due to the assigned block producer being unable to produce blocks in time. This is normal chain behaviour as described in the Nomicon consensus model. Skipped blocks are not shown in explorers, and node responses may return: "DB Not Found Error."
• Ripple - Only the most recent 45 days of historical data is available.
• Stellar - Only the most recent 12 months of historical data is available.
• SUI - Only the most recent 3 days (current epoch) of data is available.

Testnets

• BSC – Only the most recent ~128 blocks are available.
• Near – Only the most recent 1–2 days of data are available.
• Solana – Only the most recent ~30 days of data are available.
• Tezos - Rolling node maintaining only the most recent ~23,000 blocks (approximately 8 days of data). Older blocks are pruned. Current blockchain height is approximately 10.1 million blocks (as of September 2025).
