An Arbitrum check screens a 0x address against sanctions designations, scam and drainer clusters, mixer trails, exploit and stolen-funds paths, bridge activity and high-risk venues, and reports issuer freeze status for the USDT and USDC it holds. Free in the Telegram bot, three checks a day, no signup, verdict in seconds. Arbitrum is a layer-2 network, so most value arrives over a bridge — and a bridge carries history with it.

An Arbitrum check reads the account's transfers and counterparties: sanctions designations, scam and rug-pull proceeds, drainer and phishing infrastructure, mixing services, proceeds of named protocol exploits, stolen-funds trails, no-KYC venues and mule networks. Where the address holds USDT or USDC, it also reports issuer freeze status.
The verdict is CLEAN, LOW, MEDIUM, HIGH or CRITICAL, with a recommendation and the decision drivers named. On a layer-2 network the reason line does most of the work, because a large share of the value on the chain did not originate there. Funds that crossed a bridge bring their history along, and the result names what that history is rather than treating the bridge as a fresh start.
Sanctions are checked against the public record: OFAC's definitions are in FAQ 559, the blocking obligation on its virtual currency FAQ topic page.
Arbitrum is EVM-compatible, so an address is 0x plus 40 hexadecimal characters with the EIP-55 checksum in the capitalisation — for example 0x5aAeb6053F3E94C9b9A09f33669435E7Ef1BeAed. No memo, no tag.
The identical shape across EVM networks is the practical hazard:
ETH used for gas on Arbitrum has no issuer and cannot be frozen. The stablecoins can be. Tether's terms allow it to "freeze any Tether Tokens held by you" (Section 2) and to "blacklist Digital Token Addresses" where prohibited use is suspected (Section 8) — tether.to/en/legal. Circle's USDC terms reserve the right to block USDC addresses and to block "the transfer of USDC to and from an address on chain as permitted under the blocklisting policy" — circle.com/legal/usdc-terms.
Then there is the venue layer: a centralised exchange that holds an Arbitrum deposit pending review of where the funds came from. That review is theirs, not the issuer's, and a check before the transfer is what avoids it.

Individual transfers go through the Telegram bot. A venue or a treasury moving value across layer-2 networks daily should call the API and work exceptions in the workspace.

No. A bridge moves value from one network to another; the chain of custody survives the move and screening follows it. The result names the origin of the value rather than treating the bridge as a clean start. If you received funds that came back flagged, document where they came from — that is what helps.
The string is the same, the balances and history are not. Each network keeps its own record, so screen the network where the transfer actually settles and select that network on the sending side.

Yes, at the issuer level. Tether reserves the right to freeze tokens and blacklist addresses under Sections 2 and 8 of its terms; Circle reserves the right to block USDC addresses and on-chain transfers under its blocklisting policy. Gas ETH cannot be frozen.
HIGH means exposure a compliance team would act on: sanctioned counterparties, exploit or drainer proceeds, stolen funds, scam distributions. The recommendation is Review or Reject — hold the transfer until the source of funds is documented.
