Asset transfers (filtered)

Filtered transfer log for an EVM address: one direction (in or out), optional counterparty, a category subset (external / internal / erc20 / erc721 / erc1155 / specialnft), an optional contract filter (e.g. only USDC), a block range, and a cursor for paging. One indexed query per call - the cheap way to ask 'every USDC transfer into this wallet' or 'all transfers from A to B' without scanning logs. Values are exact decimal strings scaled by the token's decimals; each row carries the block timestamp.
