Look up whether an address is a labelled centralised-exchange wallet in Scienter's published exchange-wallet table, whether any address clustered with it is, and what the address's own exchange activity looks like: its deposits to labelled exchange wallets and any per-user deposit addresses inferred from its behaviour, read from real transfer history (activity.checked says whether that read ran).

The table is small (tens of addresses, from public block-explorer labels, activity-checked on chain) and a miss means no label is held -- not that the address is unaffiliated with an exchange.

Critical limit on what a hit means: an exchange hot or cold wallet is paid by millions of unrelated people. Two addresses that both funded the same exchange wallet are two customers of that exchange and nothing more. Each row carries a clusterable flag saying whether it can be used to link addresses at all; this must be repeated whenever the result is restated.

Args:

• address (string): an EVM 0x address or a base58 Solana address.
