ERC20_Transfer_event

ERC-20 token transfer events decoded from transaction logs, containing sender address, recipient address, and token amount. Primary source for tracking fungible token flows and wallet holdings across EVM-compatible blockchains.

Columns

Column	Type	Description
`block_timestamp`	`TIMESTAMP`	Timestamp when the block was produced. UTC timezone, millisecond precision.
`block_number`	`INT64`	Sequential identifier for the block in which the event or transaction was recorded. Integer value indicating the block’s position in the blockchain.
`transaction_hash`	`STRING`	Unique identifier for the transaction. 66-character hex string including 0x prefix.
`log_index`	`INT64`	Position of the event within the block’s transaction logs. Zero-indexed integer representing the sequential order of log emission.
`address`	`STRING`	Contract address that emitted the event. Hex-encoded, 0x-prefixed, 42-character string.
`removed`	`BOOL`	Boolean flag indicating whether the event log was removed from the blockchain due to a chain reorganization.
`in_from`	`STRING`	Address originating the transfer or operation. Hex-encoded, 0x-prefixed, 42-character string.
`in_to`	`STRING`	Destination address receiving tokens or assets in the operation. Hex-encoded, 0x-prefixed, 42-character string.
`in_value`	`STRING`	Amount of tokens transferred, minted, or burned in the operation. Numeric string representation preserving precision for large integer values.
