Right now, you just want to understand why your swap is under review and what happens next. This guide explains what an “under review” status means, what you can do next, and what to expect during the review process.

There is an emotional side too. “Under review” can feel concerning, but it does not necessarily mean that you have done anything wrong. This guide focuses on what can help: understanding what the status means, what information may be requested, and what to expect next.

The timing also marks an anniversary. SimpleSwap and AMLBot have now worked together for a year, supporting self-custody while applying appropriate transaction-screening controls. Instead of issuing a press release, we put together this guide with both teams.

The division of work is simple. SimpleSwap organizes the swap: crypto moves between wallets via multiple liquidity providers, and the platform is non-custodial and does not take custody of users’ funds. AMLBot is an all-in-one crypto compliance platform that has been screening wallets and transactions for risk exposure since 2019. In this partnership, it provides the screening layer that helps identify potential risk indicators associated with a transfer.

Screening happens at two points, and it helps to know which one you are at. Your deposit is screened once it has been confirmed on-chain, which is why a swap can go under review after you have already sent the funds and nothing has arrived back yet. The address the swap is due to pay out to is screened as well before anything leaves. Either check can result in additional review based on the risk indicators it surfaces.

What this guide covers

• Why transaction screening is used and what the data behind it actually looks like.
• What to do next if a swap is subject to additional review.
• How to check an address or a transaction before you swap, so you can see the risk before you take it on.
• When KYC or additional verification may be requested during a review.
• Answers to the questions that come up most.

Why Transaction Screening Exists

Screening exists for a simple reason: crypto is strongest at moving value quickly without intermediaries, and that is exactly what makes it attractive for moving stolen or illicit funds. That is not a problem unique to SimpleSwap. It is an industry-wide issue, which is why we partner with AMLBot, a crypto compliance platform that covers wallet screening, real-time transaction monitoring, identity verification, and blockchain investigations, and is used by more than 1,000 crypto businesses worldwide.

AMLBot has been screening crypto wallets and transactions for risk exposure since 2019. Across more than 500,000 wallet checks run by users, the platform has flagged over $100M in risky funds: money carrying exposure to scams, hacks, sanctioned entities, darknet markets, mixers, or ransomware.

What that risk actually looks like is less cinematic than most people expect. AMLBot published a Crypto Crime Report for 2025 to 2026, built on more than 2,500 real investigations, and the single largest driver was social engineering: phishing links, fake support agents, impersonated project teams accounted for 65% of the cases handled in 2025. Not broken cryptography, but people persuaded to approve a transaction or hand over access.

Once funds are taken, they rarely sit still. A separate AMLBot analysis traced $4.2B in stablecoins moving through six major privacy protocols, broken down by chain and risk profile. That is the machinery screening is built to notice: funds that may have been moved, bridged, or routed through services that can make their source more difficult to trace.

Here is the part that matters most if you are reading this after a swap went under review. Screening is not primarily about the person initiating the transaction. It is about the history the funds carry with them. An address may be flagged based on its transaction history and identified exposure, rather than solely on the identity of its current user, and the same filtering that helps identify exposure to potentially illicit funds also helps reduce the risk of such funds reaching your wallet through a subsequent swap.

Your Action Plan If a Swap Is Under Review

The fastest way through a review is knowing what to expect before you are in one. Here is the general process.

• Check your email and the support chat first. This is the fastest way to learn what is actually needed, and requests are usually specific about which documents apply.
• Have your order ID ready. Support needs this to pull up the specific transaction, so find it before reaching out, not after.
• Gather the requested documents. Requests vary by case, but they typically draw from this set:
  • A government-issued ID for identity verification.
  • A short selfie or liveness check to confirm the ID belongs to you.
  • Proof of where the funds came from, such as an exchange receipt or wallet transaction history.
  • For fiat-linked cases, a source-of-funds document, such as a payslip or bank statement.

Support will specify exactly which of these apply. There is no universal checklist because every case is different.

• Submit through the official channel only. Support will point to a specific ticket or secure upload link. Documents sent through unsolicited emails or third parties offering to help should be treated as a red flag, not a shortcut.
• Expect a timeline tied to what is missing, not a fixed date on a calendar. Review timelines vary depending on the information required and the circumstances of the case. Cases involving an external liquidity provider or a regulator take longer due to factors outside SimpleSwap’s control.
• Stick to one ticket. Opening a second ticket, or raising the same case across multiple channels at once, splits the history and slows things down instead of speeding them up.

How to Avoid Receiving Risky Crypto Before a Swap

Here is the part most people do not realize until it happens to them: you can do everything right and still receive funds that carry risk indicators from earlier transactions. If a wallet that sent you crypto was previously involved in a transaction with potential risk indicators, that history may be relevant when a later transaction is assessed, including any swap you initiate afterward.

The fix is not complicated. Check an address before accepting funds from it or before swapping something you recently received, just as you would check a courier before signing for a package. That is exactly what AMLBot wallet screening is for.

An AML check answers one question: has this been exposed to funds or activity that may be associated with elevated AML risk indicators? There are two ways to ask it, and the difference matters. An address check looks at a wallet as a whole: its transaction history, the addresses it has interacted with, and the risk indicators associated with those connections. A transaction check looks at a specific transfer by its hash, the funds that actually moved, and the direction they came from. You paste in an address or a transaction hash, pick the blockchain, and the check runs against that. It works in the AMLBot Telegram bot, in the web dashboard, or through the API if you are building it into your own product. Coverage is 35+ blockchains and 350+ assets, including USDT and USDC on both TRC-20 and ERC-20.

What comes back are the risk indicators associated with those connections. The report shows a percentage risk assessment, the risk categories behind it, and blacklist status, with wallet balance and cluster data where available. The categories provide additional context for interpreting the assessment: a result driven by mixer exposure is a different situation from one driven by an indirect link to an unidentified service. AMLBot screens for risk indicators and exposure associated with categories such as scams, stolen coins, mixers, sanctions, darknet markets, ransomware, fraudulent exchanges, and other high-risk sources.

This also explains a result that catches people out. An address can show a low overall risk assessment while a single incoming transfer to it shows higher-risk exposure, because one recent deposit moves the picture very little at the level of the whole wallet. If what you care about is the specific payment someone just sent you, check it by transaction hash, not only by address.

If the result comes back high risk,treat it as information rather than a verdict. High exposure does not prove anything illegal about the sender, but it does indicate that accepting the transfer may increase the likelihood of additional review, either when you move the funds or when a service screens them. Before the transfer, you may consider asking the counterparty for additional information about the source of funds and retaining relevant supporting information. If the funds have already arrived, a screening report is useful to have on hand if a service provider asks questions.

Two honest caveats. Checking an address in advance does not change how a swap is screened afterward, because screening applies to the transaction either way. And no screening tool can promise that a given service will accept a given transfer. What a check does is provide additional risk information before you decide whether to proceed, rather than only after the transfer.

How KYC Works

KYC, short for Know Your Customer, is identity verification, and on SimpleSwap it appears differently depending on when it occurs.

At registration. Creating an account and completing KYC once is optional for most crypto-to-crypto swaps. Doing it upfront may give access to a broader pool of liquidity providers and reduce the need for repeated verification later, since the check can be reused across participating providers where applicable, rather than being repeated for each one.

During a review. If a specific transaction is selected for additional review, KYC may be requested even from someone who has swapped without an account before. This is not a policy change or a punishment. It is one of the steps that may be required as part of the review process, including verifying the identity of the person involved in the transaction. The documents involved are the same ones covered in Section 2.

Either way, verification happens once per identity, not once per swap. Completing KYC during a review does not mean repeating it for future transactions, unless additional verification is required due to changes in the account, the activity, applicable requirements, or other relevant circumstances.
