What it returns

The normal transactions a wallet sent to one counterparty, received from it, or both, newest first, however busy either side is. A transaction is listed when one side sent it and the other is its direct recipient: a token transfer is listed under the token contract it called, not under the wallet it paid, and value moved inside another transaction is not listed. truncated says older transactions of the pair may exist beyond limit.
