What it returns

The first transaction that changed a wallet's balance: when (slot and time), in which token and by how much. Without token that is the first change in ANY token — often a token rather than SOL; pass token=So11111111111111111111111111111111111111111 for the first native-SOL change. It does not name who sent the funds; for the funder see wallet-funding.
