FRIEND_claimA_function

Token claim transactions from Friend.tech’s airdrop contract on Base. Contains Merkle proof verification data, claim amounts in wei, and recipient addresses for analyzing airdrop distribution patterns.

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.
`trace_address`	`STRING`	Hierarchical position of the internal call within a transaction’s execution trace. Comma-separated sequence of integers representing the call path, where each number indicates the index of the call at that nesting level, with null representing top-level calls.
`status`	`BOOL`	Transaction execution outcome indicator. Boolean value where true represents successful execution and false represents failed execution.
`from_address`	`STRING`	Address that initiated the transaction or contract call. Hex-encoded, 0x-prefixed, 42-character string.
`to_address`	`STRING`	Address receiving the transaction or contract call. Hex-encoded, 0x-prefixed, 42-character string.
`value`	`FLOAT64`	Amount of native cryptocurrency sent with the transaction. Floating-point representation in whole units (e.g., ETH, BNB, MATIC).
`gas_used`	`INT64`	Amount of gas consumed by the transaction execution. Integer representing the actual computational steps used.
`gas`	`INT64`	Gas limit allocated for the transaction execution. Integer representing the maximum computational steps allowed.
`signature`	`STRING`	Function selector identifying which contract function was called. 10-character hex string including 0x prefix.
`in_proof`	`ARRAY<STRING>`	Merkle proof array for verifying claim eligibility or settlement authenticity. Array of hex-encoded hash strings used in cryptographic verification.
`in_recipient`	`STRING`	Address designated to receive the output tokens from a swap or operation. Hex-encoded, 0x-prefixed, 42-character string.
`in_amount`	`STRING`	Input amount for the swap, transaction, or operation. Numeric string representation of token quantity in smallest denomination.
`in_giftRecipients`	`ARRAY<STRING>`	Array of recipient addresses for gift allocations associated with this claim transaction. Typically empty when no gifts are being distributed alongside the primary claim.
`in_giftAmount`	`STRING`	Token amount allocated for gifting to other recipients in the claim transaction, denominated in wei (18 decimals). Typically zero when users claim only for themselves without distributing gifts.
