Token Transfers | Ethereum EVM Blockchain Data

**Dataset Overview**

BlockDB Token Transfers normalizes all on-chain value movements - native ETH, ERC-20, ERC-721, and ERC-1155 transfers - into a single unified Snowflake table, removing the need to query and reconcile multiple event sources. Transfers are sourced from three origins and tagged with TRANSFER_TYPE: top-level transactions (native_tx), internal call traces (native_internal), and contract Transfer event logs (erc20, erc721, erc1155). Both raw amounts (AMOUNT_RAW) and decimal-adjusted amounts (AMOUNT_ADJ) are provided. Only transfers for fully identified token contracts are included, ensuring clean, reliable results for wallet analytics, compliance, and portfolio pipelines without additional filtering.

**Sample Notice**

This dataset contains **a small sample** of the full BlockDB Token Transfers dataset. It is provided **for evaluation, research, and interoperability testing only**. If you need full historical coverage, real-time streaming, or end-of-day (EOD) exports please contact us via contact form on Snowflake Marketplace.

**Chains and Coverage**

ETH, BSC, Base, Arbitrum, Unichain, Avalanche, Polygon, Celo, Linea, Optimism (others on request). Full history from chain genesis; reorg-aware real-time ingestion and updates.

**Join Keys**

TOKEN_ADDRESS → CONTRACT_ADDRESS in BLOCKDB0201_ERC20_TOKENS_V1, BLOCKDB0202_ERC721_TOKENS_V1, or BLOCKDB0203_ERC1155_TOKENS_V1 for token metadata. (BLOCK_NUMBER, TX_INDEX) → BLOCKDB0102_TRANSACTIONS_V1 for full transaction context.

**Lineage**

Each transfer record includes deterministic _TRACING_ID and _PARENT_TRACING_IDS, providing verifiable provenance from the originating transaction, internal call, or event log through to the normalized transfer record stored here.

**Quality**

- Verifiable lineage: deterministic cryptographic hashes per row
- Reorg-aware ingestion: continuity and consistency across forks
- Complete historical coverage: from chain genesis to present
