How this service works
TraceFast knowledge graph: top counterparties of an Ethereum address, current or as of a block. Up to 100 addresses it interacts with most, ranked by successful transactions across top-level calls, internal calls and token transfers, each with transaction counts and first/last block. Query: block (historical cut, optional), limit (1..100). Docs: https://docs.tracefast.xyz/api/address-counterparties
Output
A ranked list of up to 100 Ethereum addresses that the queried address has interacted with most, each entry including the counterparty address, aggregated transaction counts (top-level calls, internal calls, token transfers), and the first and last block numbers of their interactions.
Example use cases
DeFi wallet network analysis
“Give me the top 50 counterparties for the Ethereum address 0xAbCd1234... so I can see which protocols and wallets it interacts with most frequently.”
Historical counterparty snapshot
“Pull the top 100 counterparties for Ethereum address 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D as of block 18000000 so I can see who it was interacting with at that point in time.”
Exchange wallet due diligence
“I'm doing due diligence on 0xBE0eB53F46cd790Cd13851d5EFf43D12404d33E8 — can you fetch its top counterparties on Ethereum so I can understand its main transaction relationships?”
Technical details
Endpoint
GEThttps://mpp.tracefast.xyz/api/v1/chains/1/addresses/:address/counterpartiesWhen to prefer
Use this endpoint when you need to map the on-chain social graph of an Ethereum address — specifically who it interacts with most and how often — across top-level calls, internal calls, and token transfers. It is ideal for due diligence, wallet profiling, DeFi relationship mapping, and compliance checks. Prefer this over raw transaction queries when you need pre-ranked, aggregated counterparty data rather than raw transaction lists.
Side effects
- Invalid Ethereum address format returns an error
- Block number out of range or not yet mined returns an error
- Limit outside 1–100 range returns a validation error
- Address with no transaction history returns an empty list
- Payment not received or insufficient USDC results in 402 response
- Network congestion may cause timeouts on heavily active addresses
