How this service works
Whale alerts: the largest recent ERC-20 transfers (default USDC over $1M) in the latest blocks, with sender, receiver, amount and mint/burn flag. Works for USDC, USDT, DAI or any token on 5 EVM chains.
Output
A list of recent large ERC-20 token transfers on the specified EVM chain, each including sender address, receiver address, transfer amount, token symbol, block number, transaction hash, and a mint/burn flag indicating whether the transfer originated from or went to the zero address.
Example use cases
Stablecoin whale alert dashboard
“Pull the top 50 USDC transfers over $5M on Ethereum from the past 1000 blocks — I want to see who's moving large amounts and whether any are mints or burns.”
DeFi arbitrage opportunity detection
“Check the last 200 blocks on Arbitrum for any USDT transfers above $2M and show me the senders and receivers — I'm looking for whale flows that might signal arbitrage.”
Token launch whale monitoring
“Scan the last 2000 blocks on Base for large transfers of token address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 with a minimum amount of 500000 — show me up to 20 results.”

Endpoint
GEThttps://bess-x402.onrender.com/v1/crypto/whale-transfers?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time on-chain whale activity detection for major stablecoins (USDC, USDT, DAI) or any ERC-20 token across five EVM-compatible chains. It is ideal for agents monitoring large capital flows, detecting mint/burn events, or building DeFi analytics dashboards. Prefer this over general blockchain explorers when you need structured, filtered results by minimum transfer size without writing custom on-chain queries.
Side effects
- Invalid chain name returns an error (accepted: ethereum, base, arbitrum, optimism, polygon)

- blocks parameter out of range (must be 1-2000) returns validation error
- limit parameter out of range (must be 1-100) returns validation error
- No transfers found meeting the minimum amount threshold returns empty results
- Chain RPC unavailability may cause timeout or partial results
- Payment of $0.003 USDC required per call; missing payment returns 402
