How this service works
TraceFast live Ethereum data: what a reference means. An address (`0x` + 40 hex) is described — the name TraceFast shows for it, how it presents it, what kind of address it is, its token identity. Query q: What to resolve: an address (`0x` + 40 hex, any case), or a name, ENS…; limit: 1..=20, default 10. Docs: https://docs.tracefast.xyz/api/entity-resolve.md
Output
Returns the TraceFast-assigned display name, address type classification (e.g. EOA, contract, token contract), token identity information (name, symbol, standard), and presentation metadata for the queried Ethereum address or ENS name on mainnet (chain ID 1).
Example use cases
Identify unknown wallet in transaction
“Can you tell me what TraceFast knows about the Ethereum address 0xdAC17F958D2ee523a2206206994597C13D831ec7 — what name it shows, what type it is, and whether it's a token contract?”
Resolve ENS name to labeled entity
“Look up the ENS name uniswap.eth on Ethereum and tell me what address it resolves to and what kind of entity TraceFast identifies it as.”
Enrich DeFi protocol address for display
“I have the address 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D — can you resolve it on Ethereum mainnet and get me its human-readable name, type, and any token identity so I can label it in my dashboard?”
Technical details
Endpoint
GEThttps://mpp.tracefast.xyz/api/v1/chains/1/resolve?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve or label an Ethereum mainnet address or ENS name with TraceFast's curated knowledge graph — particularly when you want entity type classification and token identity alongside the name, rather than a raw ENS resolver or block explorer scrape. Ideal for enriching transaction data, labeling addresses for display, or identifying whether an address is an EOA, contract, or token.
Side effects
- Invalid address format (not 0x + 40 hex) returns an error
- ENS name not found or not registered returns empty or null result
- Address exists on-chain but has no label in TraceFast knowledge graph, returning minimal metadata
- Rate limit or payment failure returns 402 or 429 status
- Network timeout if Ethereum node is temporarily unavailable
