The tab mapper is a handy little tool that will render a guitar tab file with graphic chord diagrams displayed alongside. This comes in handy for people who just don't have every single chord shape memorized. Just plug in the web site address of a valid .tab or .crd file and hit "Go". In general, the tab mapper does a better job with printer friendly URLs. If there is more than one way to play a chord, the tab mapper will choose the most common shape. To see other fingerings, click on the chord diagram and you will be taken to the chord calculator.

Documents for a crypto exchange AML check should form a package tailored to the specific request: account status, case number, and a table of major amounts linked to TxIDs and evidence, not an archive of every available file. The package should answer the reviewer's question about a transaction or restriction. This differs from explaining Source of Funds (SoF); see what exchanges actually request for Source of Funds. If withdrawals are already on hold, see exchange account unfreezing.
An exchange usually requests AML review documents after a risk-control pause related to a deposit, withdrawal, counterparty, or account behavior. The goal is not to provide a life story, but a coherent package that addresses the exact wording in the email or case. For context on why these holds occur, see what AML means in crypto.
Source of Funds (SoF) is a separate layer: it explains the origin of a specific amount or deposit. One request may require both SoF evidence and supporting case documents. Keep the purposes distinct. The SoF article explains the chain from source to transfer to account balance; this article covers the contents of an AML case package and what should not be included. See the detailed Source of Funds guide.
As a practical starting point, read the request literally: additional verification, origin of funds, or proof of address. Then prepare one package addressing those points. For a general plan during the first day of a restriction, see frozen crypto: what to do.
The basic structure is similar across major exchanges:
Platform help materials describe this as additional information or additional verification for withdrawal. Respond through the account's official channel with one package containing legible dates and amounts. Public lists from Kraken, Bybit, and OKX illustrate common practice, but the request in your case may narrow the list to two or three items. Follow that request rather than someone else's chat template.
If the request expressly concerns the source of funds, include SoF files but build the evidence chain using the Source of Funds guide, not a bundle of balance screenshots. A counterparty's blockchain trail may sometimes require blockchain analytics; this does not replace identity or financial documents.
Attempts to accelerate the process by bypassing it are also harmful: a second account, changing location through a VPN during the review, routing transfers through friends, or using urgency across five parallel tickets. To a risk model, these can look like attempts to evade controls. A seed phrase, private keys, and 2FA codes never belong in an AML package, whether it is sent to an exchange or a Telegram helper.
If the restriction is active, first record the facts and use one communication channel. See the checklist in frozen crypto: what to do. Improving the package is more useful than resubmitting the same archive three days later.
Review the package as an investigator would: are the dates legible, do the amounts reconcile, and does each file address a specific item in the request? If the hold affects withdrawals, keep the exchange account unfreezing route in view. The outcome is not guaranteed and depends on platform policy and the quality of the package.
