How this service works
Send guard for Arc: call it BEFORE sending USDC or a token. Pass ?from=<sending wallet>&to=<destination> (and &token=0x... for a token send). Returns verdict stop / check / ok with reasons: the destination is a lookalike of an address the sender really used (address poisoning), bait planted in the sender's history by a forged transfer, a token contract or the burn address, on the OFAC SDN list or USDC's own blacklist; the token is a fake USDC / EURC; or a brand-new address (check).
Output
Returns a verdict of 'stop', 'check', or 'ok' along with a list of reasons explaining any risk flags. Reasons can include: the destination is a lookalike of a previously-used address (address poisoning), a bait address planted via a forged transfer, a known token contract or burn address, listed on OFAC SDN or USDC blacklist, a fake USDC/EURC token contract, or a brand-new address (triggering 'check').
Example use cases
Safe USDC send to new recipient
“I'm about to send USDC from 0x1111111111111111111111111111111111111111 to 0x2222222222222222222222222222222222222222 on Arc — can you check if the destination is safe, not a lookalike of someone I've sent to before, and not on any blacklist?”
Token transfer poisoning check
“I want to send this token at 0xAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA from my wallet 0xBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB to 0xCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC — check if the destination looks suspicious or if someone planted a bait address in my history.”
Pre-send OFAC and blacklist screen
“My wallet 0xDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD is about to pay 0xEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE — can you verify the recipient isn't on the OFAC SDN list or USDC's blacklist before I confirm?”
Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/arc-send-guard?utm_source=zero.xyzWhen to prefer
Use this endpoint specifically when operating on the Arc network and needing a pre-send safety check that covers address-poisoning lookalikes, forged-transfer bait addresses, OFAC/USDC blacklists, and fake stablecoin contracts in a single call. Prefer it over generic wallet-screening tools when the sender's own on-chain history needs to be cross-referenced for lookalike detection, or when the token being sent needs to be verified as genuine USDC/EURC.
Side effects
- Missing required 'from' or 'to' query parameters — returns error
- Invalid address format (not a valid 0x hex address) — returns validation error
- Payment not included or insufficient — returns 402 Payment Required
- Destination address not resolvable on Arc — may return incomplete check
- Network or upstream data source unavailable — may return degraded verdict
