An OTC desk can receive a new address while a dealer is still negotiating the price. An exchanger may handle several unrelated customer payments in the same shift. In either case, the problem is keeping screening evidence attached to the right trade. A result floating in a chat is hard to audit and easy to reuse by mistake. Build the wallet check into the ticket before speed makes the context disappear.
Give every check a trade context
Record the customer reference, proposed sending address, network, asset, intended amount and receiving instructions. Keep a clear distinction between an address supplied before settlement and the actual transaction that arrives. If a service processes the customer's withdrawal, the on-chain sender may need an explanation rather than an assumption.
A2 Route's public pages describe address and USDT/USDC transaction screening on TRON and Ethereum. Use that published scope when planning the workflow. A supported address check is not a general approval for every asset the desk trades. The incoming USDT guide covers establishing the receiving details before payment.
Use internal ticket identifiers that cannot be confused with transaction hashes. A training record could say FAKE_OTC_TICKET_01 and FAKE_WALLET_NOT_AN_ADDRESS, explicitly marked synthetic. These are invalid demonstration labels. Do not populate training systems with public wallets belonging to real people or services just to make an example look authentic.
Decide who owns a held trade
Write down who can pause settlement, who reviews a flag and who can approve an exception. Dealers should know whom to contact without inventing a rule during a busy shift. The reviewer needs the whole result and the trade context, not a message saying “score looks fine.”
Use operational language for these rules. Holding an order while reviewing a wallet is your business procedure, not proof that a specific threshold satisfies a regulator. Avoid presenting an ALLOW result as a compliance certificate. Screening does not verify the customer's off-chain identity, beneficial ownership or purpose of payment, as the sample report's limitations explain.
Put the check before the action it informs
Before an incoming transfer, check the intended sender where the network and subject are supported. After the transfer exists, compare it with the ticket and review the actual supported transaction. Before an outgoing settlement, confirm the destination instructions and screen the relevant subject. Do not substitute an incoming check for a destination review.
If the customer changes the wallet after review, record the reason and treat the new wallet as a new subject. Do not let an earlier result travel with the customer name indefinitely. The result concerns what was checked at a recorded time. A different payment or a different address can require different evidence.
Review flags without losing their meaning
A2 Route's public report description includes a verdict, score, source shares, top exposure, sanctions lists and a risk-categories appendix. Read them together. Distinguish direct exposure from a path through intermediaries and distinguish a list match from an exposure label. The direct and indirect exposure guide gives a practical reading framework.
A score should trigger an understandable action, not a debate about a number in isolation. The risk-score guide explains why it is not a probability of guilt or a measure of how much of a specific payment is unlawful. A reviewer should be able to state the actual finding and what it means for this ticket.
When a result is partial, retain the limitation. The A2 Route FAQ says partial coverage is reduced and recommends a re-check. If settlement must wait, tell the dealer exactly what is missing and who decides whether to proceed. Do not silently replace a failed or incomplete check with an assumed safe result.
Retain evidence a new shift can follow
Keep the report or result with the trade reference, payment details, correspondence and reviewer decision. Record when checks were performed and preserve earlier versions when labels change. A colleague taking over the next shift should be able to tell which result applies to which leg of the trade without searching an entire chat history.
Paid A2 Route checks can include a PDF report. The public pages say the report API returns its file SHA-256 for verification. See the report walkthrough before designing your archive. File integrity answers whether a retained file matches the stored copy; it does not establish ownership or approve the underlying trade.
Keep the workflow small enough to use
Start with a ticket checklist and a named reviewer. Check that the team actually records wallet changes and exceptions. If you later integrate screening into your systems, use the A2 Route business API documentation and retain the distinction between request status, available evidence and the desk's settlement decision. Do not infer an automated settlement guarantee from the existence of an API.
For repeat customers, define wallet re-check triggers and intervals. For a desk handling both supported chains, keep TRON and Ethereum identifiers attached to the correct ticket.
For a flagged counterparty, follow the next-steps guide. For a separate supplier-payment leg, the A2vanta business payment blog offers further reading.
