- 80trustEntities ActivityTraceFast
TraceFast live Ethereum data: three different questions about when an address was active, each answered separately — when it was first mentioned anywhere on chain; when its own account state last changed and how many times it changed; and the newest block at which it took part in anything (a top-level transaction, a token transfer, an emitted log, a value-bearing call), with the sources that answer was… Path: address. Docs: https://docs.tracefast.xyz/api/address-activity.md
$0.01per call on Base100% uptime, 268 ms, 2 paying agentsPassing, checked 3 h ago - 80trustChains EntitiesTraceFast
TraceFast live Ethereum data: one address as the chain sees it now — how it exists (an account whose state was touched, or an address only ever mentioned by other operations), whether it holds code, its native balance and nonce, when it was first mentioned and last active in any form, and its direct-transaction counters. Path address: The address, `0x`-prefixed, 40 hex characters, any case. Docs: https://docs.tracefast.xyz/api/address.md

TraceFast knowledge graph: the relations an address was the subject of at the end of one block — which implementation a proxy pointed at, which beacon it read, who administered it, where an account had delegated — each with the window it held for. Path address: The address, `0x`-prefixed, 40 hex characters, any case. Query block: The block to answer about. Docs: https://docs.tracefast.xyz/api/address-relations-at-block.md
$0.025per call on Base100% uptime, 284 ms, 2 paying agentsPassing, checked 3 h ago - 80trustEntities RelationsTraceFast
TraceFast knowledge graph: the relations an address holds now — which implementation a proxy points at, which beacon it reads, who administers it, where an account has delegated, which lending market lists a token — as the subject (`direction=subject`: what it points at, default) or as the object (`direction=object`: who points at it). Path: address. Query: direction, attributeId, limit, cursor (see docs). Docs: https://docs.tracefast.xyz/api/address-relations.md

TraceFast knowledge graph: what an Ethereum address is, as proven facts — wallet or contract, proxy and upgradeable or not, a token and its standard, and for a token contract whether it can pause, mint or blacklist and whether it ever did.

How these numbers are made
Each listing is called on a schedule without paying. Listings with usage or a verified owner are checked about every 30 minutes, others about every 6 hours. Uptime is the share of passing checks over 30 days, averaged across this provider's listings. Trust scores follow the published method. The figures on this page can be a few minutes behind the latest checks, and listings hidden after review aren't counted.
