How this service works
Whale-watch: a standing 30-day watch on one EVM wallet. Sweeps every 15 minutes across 6 chains; alerts the moment a transfer at or above your USD threshold moves in or out — delivered to your webhook and readable any time via the free status endpoint with your read token. Fully anonymous: no account, no email, the returned credentials are all that exists.
Output
Returns a watch token and a read token. The watch token identifies the active 30-day monitor; the read token allows querying the watch status endpoint at any time to check current state, recent alerts, and matched transfers. Webhook POSTs are sent in near-real-time when a transfer meeting the USD threshold is detected on any of the 6 supported EVM chains.
Example use cases
Monitor competitor wallet fund movements
“I need you to watch the wallet 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb for any transfers over $100,000 for the next 30 days. Send alerts to my webhook at https://api.myservice.com/alerts whenever they move funds — I want to track their capital allocation strategy across Ethereum, Polygon, and Arbitrum.”
Track treasury outflows for compliance
“Set up a watch on our organization's treasury wallet 0xE8f5E8f5E8f5E8f5E8f5E8f5E8f5E8f5E8f5E8f5 to monitor for any transfers exceeding $25,000 over the next month. Post alerts to https://compliance.ourbank.com/webhook so our finance team can flag any unusual activity in real-time across all EVM chains.”
Alert on high-volume liquidity pool withdrawals
“Can you monitor this Uniswap LP wallet 0x1234567890abcdef1234567890abcdef12345678 and notify my Discord webhook at https://webhooks.discord.com/services/... whenever there's a movement of $75,000 or more? I want to catch large exits from the pool over the next 30 days to understand liquidity dynamics.”
Technical details
Endpoint
GEThttps://taxpulse.theaslangroupllc.com/api/crypto/wallet-watch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a persistent, multi-chain whale-watch on a specific EVM wallet address with webhook delivery and no account creation. Prefer this over block-explorer manual lookups or general blockchain APIs when you need proactive alerting over a 30-day window with USD-denominated thresholds rather than raw token amounts.
Side effects
- Invalid wallet address format — returns error indicating malformed EVM address
- Webhook URL unreachable or returning non-2xx — alerts may be lost or retried depending on implementation
- USD threshold set to zero or negative — may trigger on every transfer or return validation error
- Payment not received or insufficient USDC — watch not activated
- Watch expires after 30 days — no further alerts sent, read token still returns historical status
- Chain polling temporarily disrupted — 15-minute sweep interval may be delayed
