KAST RFI Explained: Request for Information, KYC and Source of Funds

Fast money still needs clear information.

When you store, earn, move, and spend with KAST, some account checks may need an extra document, detail, or explanation. That is where an RFI comes in.

RFI means Request for Information. At KAST, it means we need extra information to complete a review linked to KYC, identity verification, Source of Funds, Source of Wealth, Proof of Address, transaction activity, or account security.

You may also see this type of request named KAST Account Review - Request for Information.

The goal is simple: clear information, safer account access, and a smoother review.

Some RFIs are simple. For example, a document may be unclear, outdated, cropped, or missing key details. In that case, a clean submission can help us move faster.

However, some RFIs ask for more detailed information. This may include the purpose of transactions, relationship details, Source of Funds, Source of Wealth, expected transaction volume, future transaction pattern, or supporting business documents.

The request will tell you what to submit. Send only what we ask for. Extra files do not always speed things up.

Why We Ask for More Information

We may send an RFI when the information we have needs to be clearer, newer, or more complete.

These requests are part of standard compliance and security processes used by regulated financial institutions and their partners. Depending on the situation, regulations or partner reviews may require additional verification before certain account activity can continue as normal.

This can happen during account verification, KYC checks, Source of Funds review, Source of Wealth review, Proof of Address verification, transaction monitoring, or account security checks.

Common reasons include:

• A document is blurry, cropped, expired, or incomplete
• A name, address, or date is missing
• Details do not match your KAST account
• Source of Funds needs clearer support
• Transaction activity needs more explanation
• Expected account activity needs confirmation

These checks help us keep account information accurate and support secure use of KAST.

Some KAST RFIs May Ask About Transactions

Not every RFI is only about document quality.

In some cases, we may ask for more information about specific transactions. The request may include transaction details such as the date, amount, sender, receiver, or payment direction.

We may ask you to explain the purpose and nature of the transaction. For example, we may need to understand whether it was linked to personal use, business activity, payment for services, investment activity, or another reason.

We may also ask for documents that support the explanation. These can include invoices, contracts, agreements, payment records, or other documents that show the underlying activity.

In some transaction reviews, we may also ask for relationship details. This may include the legal full name, date of birth, place of residence, and relationship between the parties involved in the transaction.

This helps KAST and its partners understand the transaction clearly and complete the review with the right context.

KAST RFI Documents: What We May Ask For

The exact document depends on the request.

Not every RFI needs every document. The request will explain what applies to your case.

Source of Funds: What It Means

Source of Funds shows where the money used for a transaction or account activity came from.

It can include salary, business income, savings, investments, asset sales, loans, or another legitimate source.

A useful Source of Funds document should show your name, the source of money, the date, and the relevant account or transaction details.

For example, a payslip can support salary income. A bank statement can support savings or account history. An invoice can support business income. An investment statement can support funds from investments.

The document should be clear, complete, recent, and official.

Source of Wealth: What It Means

Source of Wealth explains how your wider financial position was built over time.

This is different from Source of Funds. Source of Funds usually explains money connected to a specific transaction or account activity. Source of Wealth explains the wider background behind your financial activity.

Source of Wealth may come from employment income, business ownership, savings, investments, property sales, inheritance, or other documented sources.

If total transaction activity is high, we may ask for documents that support that level of activity. These may include bank statements, earnings records, investment documents, business documents, or proof of income.

Expected Transaction Volume and Future Activity

In some reviews, we may ask about your expected monthly or annual transaction volume going forward.

This helps us understand whether your account activity is expected to continue and why that level of activity makes sense.

For example, we may ask whether similar transaction volumes will continue in the future. We may also ask for supporting business documentation if the activity is linked to commercial use.

This can include invoices, contracts, agreements, company records, or other documents that explain the expected activity.

Clear answers help reduce back and forth during the review.

Proof of Address: What It Means

Proof of Address confirms your current residential address.

A strong Proof of Address document usually shows your full name, current address, recent date, and the issuer’s name or logo.

Common examples include utility bills, bank statements, tax letters, government letters, and lease agreements.

The details should match your KAST account. If they do not match, we may need another document.

How to Submit RFI Documents Without Delays

A clean document makes the review easier.

Before you upload, check that:

• Your full name is visible
• The date is visible
• The full page is shown
• All four corners are included
• The image is clear
• There is no glare
• The document is not expired
• The file has not been edited
• The details match your KAST account

PDF format is preferred when available.

Avoid screenshots with missing details, cropped files, blurred images, and documents that hide key information.

How to Check a KAST RFI Request

Document requests should always come through official KAST channels.

Be careful with random links or private messages that ask for sensitive information. KAST will never ask you to send funds or tokens through private messages.

Use the secure flow we provide. If something does not look right, contact Concierge before taking action.

What Happens After You Submit

After you send the requested information, we review it.

If the document, explanation, or supporting evidence is clear and valid, the review can move forward. If something is missing, outdated, hard to read, or incomplete, we may ask for more information.

In some cases, the review may involve KAST partners. For example, a banking partner may request standard details as part of a compliance or security review.

Your funds remain secure while we complete the standard verification review.

The best way to avoid back and forth is to read the request carefully and upload the exact document or explanation we need.
