FAQ
General
What is Flash Mixer?
Flash Mixer is a Bitcoin exchange service that provides delayed,
private payouts with no registration required. You specify up to 2
Bitcoin addresses to receive funds, choose a pool and fee tier,
and optionally set a time delay. We handle the settlement from our
liquidity reserves.
Do I need to register or provide personal information?
No. Flash Mixer requires zero registration. No email, no identity
verification, no personal data. You only need a Bitcoin address to
receive your payout.
How long is my order valid after creation?
Each order is valid for 24 hours from creation. If payment is not
received within that window, the order expires automatically and
is cancelled. You can always create a new order.
How many Bitcoin confirmations are required?
We require 3 on-chain confirmations before processing begins. This
typically takes 30–60 minutes depending on network conditions.
What if I send less than the required amount?
Payments below the required amount are treated as final. No
additional funds are requested and no partial refunds are issued.
Please send the exact amount shown on the order page.
What if I accidentally send more than required?
Overpayments are non-refundable and treated as voluntary
contributions. Please double-check the amount before sending.
Do you support cryptocurrencies other than Bitcoin?
Currently only Bitcoin (BTC) is supported. Payout addresses must
be valid mainnet Bitcoin addresses (bech32 / bc1..., legacy P2PKH
/ 1..., or P2SH / 3...).
What is the difference between Standard and Premium pools?
The two pools differ in liquidity source, fee structure, and delay
range. Standard Pool: 0.001–1.5 BTC, 1.5–10.0% fee + $20.0 fixed,
0–72h delay. Premium Pool: 0.01–450.0 BTC, 3.0–10.0% fee + $20.0
fixed, 2–72h delay. Premium payouts originate from freshly
allocated, zero-history outputs. Standard payouts use diversified
reserves with built-in flow management.
Website
How do I create an order on the website?
Go to Create Order. Select a pool, choose a fee percentage, enter
your payout Bitcoin address and the amount you want to receive,
optionally add a second address, and set a delay. The calculator
shows the total amount to send in real time. Confirm, and you will
receive a unique Bitcoin deposit address.
What is a payout address?
A payout address is the Bitcoin address where you want to receive
funds. You specify the net amount you want to receive; the system
calculates the total to send including all fees.
Can I split my payout to multiple addresses?
Yes. Each order supports up to 2 payout addresses, each with its
own receive amount and time delay — for example, one immediate
payout and one scheduled 12 hours later.
How do I check my order status?
On the order status page (linked after order creation), you can
see live confirmation progress, payout schedule, and transaction
hashes once available. Bookmark the page or save your order UUID
to access it later via the Check Status page.
What is the API key shown on my order status page?
After your payment reaches 3 blockchain confirmations, you receive
a one-time API key. This key grants access to higher daily order
limits via the programmatic API. The key is displayed exactly once
— save it immediately. It is never stored in plaintext on our end.
Is there a Tor (.onion) version of the site?
Yes. The Tor hidden service mirrors the full mixer functionality
and works completely without JavaScript — every action (creating
an order, checking status, PGP warranty verification) works in Tor
Browser with NoScript blocking scripts. The .onion address is
shown in the header and footer of every page on the clearnet site.
Telegram Bot
How do I start using the Telegram bot?
Search for @flashmixer_bot on Telegram and send /start. The bot
will show a menu with options to create a new order or check an
existing one.
What languages does the Telegram bot support?
The bot supports English, Russian, Chinese, Spanish, German, and
French, detected automatically from your Telegram language
settings.
How is the Telegram bot different from the website?
Both offer the same core functionality. The bot guides you through
order creation step by step with inline buttons — convenient on
mobile without a browser.
How do I check an order status via Telegram?
Tap "Check Status" in the bot menu and enter your order UUID. The
bot shows the current status, confirmation count, and payout
details.
MCP Server
What is the MCP server?
The MCP (Model Context Protocol) server lets AI agents interact
with Flash Mixer programmatically. It exposes five tools: create
order, check status, get pool configuration, calculate fees, and
trigger payment check.
Who is the MCP server designed for?
Developers and AI systems that need to create or monitor Bitcoin
exchange orders without a browser — trading bots, AI assistants,
and automated workflows.
What operations are available via MCP?
Five tools are available:
- create_exchange_order — create a new order
- get_order_status — check an order by UUID
- get_pool_configuration — fetch current limits, fees, and BTC/USD rate
- calculate_exchange_fees — calculate exact fees before creating an order
- trigger_payment_check — manually trigger payment verification for an order
How do I connect my AI agent to the MCP server?
Configure your MCP client with the endpoint #. Set the
Authorization header to "Bearer <your-token>". The server
uses HTTP Streamable transport with JSON-RPC 2.0 — compatible with
any standard MCP client.
{"url": "#", "headers": {"Authorization": "Bearer <token>"}}
