How this service works
Filtering: USDC on Base settles thousands of transfers a minute. This scans the raw feed and returns only transfers above a value threshold (?minUsd=, default $10,000) — the noise removed, not delivered.
Output
Returns an array of transfer objects each containing sender address (from), receiver address (to), transaction hash, USDC amount, and block number. Also includes metadata: the minUsd threshold used, a dataAsOf timestamp, the total raw event count scanned, and the number of blocks scanned.
Example use cases
Whale wallet movement detection
“Show me all USDC transfers on Base mainnet above $100,000 from the last scan — I want to identify which wallets are moving large amounts.”
DeFi liquidity flow analysis
“Can you fetch large USDC transactions on Base above $25,000? I'm trying to understand where big liquidity is flowing right now.”
Suspicious transaction monitoring
“Pull any USDC transfers over $500,000 on Base mainnet so I can flag unusually large movements for a compliance review.”
Technical details
Endpoint
GEThttps://lab.paidapis.net/api/large-usdc-transfersWhen to prefer
Choose this endpoint when you need to quickly query large USDC transfer events on Base mainnet without running your own blockchain node or indexer. It is ideal for whale-watching, compliance screening, or DeFi flow analysis where a configurable USD minimum threshold is useful. Prefer it over raw RPC calls when you want pre-parsed, human-readable transfer data without writing event-log decoding logic.
Side effects
- Invalid minUsd value (non-numeric) may return a validation error
- If no transfers exceed the threshold, an empty transfers array is returned
- RPC or indexing lag may cause stale data; check the dataAsOf field
- Extremely low minUsd thresholds may produce very large result sets or timeouts
- Network issues with Base RPC node may cause 500-level errors
