How this service works
Whale and large-trade tracker for an ERC-20 on Arbitrum One: every buy and sell in the last N minutes on the token's deepest WETH/USDC pools (Uniswap v3), with USD size, side, wallet and transaction for the largest trades, buy/sell volume and net flow, and the wallets that bought or sold the most.
Output
Returns a JSON object with: token metadata (symbol, address, decimals), the actual time window and block range covered, a summary of total buys/sells/trades, buy volume USD, sell volume USD, net flow USD, and largest trade USD. Also includes an ordered list of top buyer wallets and top seller wallets with per-wallet trade count, bought/sold/net USD. Individual large trades list each trade with transaction hash, DEX, USD size, buy/sell side, block, wallet, and approximate timestamp. Includes ETH/USD price used and notes on pool coverage.
Example use cases
Whale accumulation alert for ARB
“Check if any whales are accumulating ARB on Arbitrum right now — show me trades over $1000 in the last 60 minutes, who bought the most, and what the net flow looks like.”
Detecting sell pressure before a trade
“Before I buy this Arbitrum token at 0x912CE59144191C1204E64559FE8253a0e49E6548, can you check if there's been heavy selling in the last 30 minutes? I want to see top sellers and total sell volume vs buy volume.”
Post-news token flow analysis
“A major announcement just dropped for this Arbitrum token — pull all large trades over $5000 in the last 45 minutes for 0x912CE59144191C1204E64559FE8253a0e49E6548 and tell me who the biggest movers are on the buy and sell side.”
Technical details
Endpoint
GEThttps://onchaincheck.dev/arbitrum/trades?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time whale and large-trade intelligence specifically for an ERC-20 on Arbitrum One via Uniswap v3 WETH/USDC pools. It is the right choice when you need per-wallet attribution, net flow direction, and individual trade details in one call. Prefer it over generic block explorers when you want structured, pre-aggregated buy/sell analytics rather than raw transaction data. Not suitable for tokens that trade primarily on other DEXes, other chains, or pairs other than WETH/USDC.
Side effects
- Invalid or non-ERC-20 token address returns error or empty results
- Token with no Uniswap v3 WETH/USDC pools on Arbitrum returns zero trades
- Minutes parameter outside 5-240 range may be rejected or capped at ~50 minutes (12,000 blocks)
- Limit parameter outside 1-40 range may be rejected
- Network or RPC errors on Arbitrum One may cause timeouts
- Very new tokens with no trading history return empty trade lists
