A JSON response. Every field is always present; null means the value could not be established, never zero.

Response fields of Wallet funding source
Field	Type	Description
`funders`	object[]	Every address the source attributes to the wallet's FIRST known funding event — not its most recent funder. Usually one entry; occasionally more when that single funding transaction combined more than one source address. Always an array, never `null`; empty when the source has nothing on this wallet.
`funders[].address`	string
`funders[].label`	string \| null	A known label for the funder (e.g. an exchange's hot wallet), or `null` when the source has no name for it — never an empty string.
`amountNative`	number \| null	The amount moved in the first funding event, in the chain's native coin (SOL, ETH or BNB), or `null`.
`amountSol`	number \| null	Equal to `amountNative` on Solana; `null` on every other chain.
`txHash`	string \| null	The first funding transaction's hash, or `null`.
`fundedAt`	integer \| null	Unix seconds of the first funding event, or `null`.
