Blockchain Database LTD
We’re a team of data engineers and quants. We transform raw on-chain events into lineage-verified, schema-stable datasets that your team can trust and use immediately - reducing data prep time and accelerating decisions across research, trading, and product.
Every record we deliver comes with a mathematical receipt you can independently verify (Merkle Tree). You can always ask: where did this come from, and was it computed correctly?

BlockDB EVM Function Results
Deterministic record of contract function call outputs at specific block heights. One row per (contract incarnation, block, call data) combination, enabling time-travel queries over any contract's view function state with audit-grade lineage. Use Cases - Historical state reconstruction and time-travel queries - Token metadata and balance lookups at specific blocks - Contract configuration and parameter tracking over time - Price oracle and external data feed analysis

BlockDB EVM Internal Transactions
Full call-trace decomposition of every EVM transaction via debug_traceTransaction. One row per internal call, with the complete call tree position, call type, value transferred, gas used, and input/output data — providing complete internal execution visibility beyond top-level transactions. Use Cases - Contract creation and factory flow analysis - Internal call graphs and cross-contract dependencies - Debugging failed transactions and revert reasons - Native ETH transfer tracking

BlockDB EVM Logs
Complete event log records for every log emitted by smart contracts across EVM chains. One row per log entry, with raw topic and data payloads directly verified by RLP, and deterministic row-level tracing back to the originating block. Use Cases - DeFi protocol event tracking (swaps, transfers, mints, burns) - Token transfer and balance change monitoring - Smart contract interaction analysis - Protocol state reconstruction from events - Cross-contract event correlation and analysis
