EndpointOne listed wallet: every active listing of the address (category, source, wording, date, link), its last known balances on the scanned EVM chains (native ETH and the curated tokens, at our own prices) and its tracked movements, newest first (every token on Ethereum, Arbitrum and Base, native ETH on Ethereum, Bitcoin; within the plan history). A token outside our curated list is marked unverifiedToken and never priced. The other side of a movement keeps only its own sourced label (exchange proof of reserves, protocol docs) or none. 404 when the address has no active listing.
