Answers about Flash Mixer pools, fees, delays and privacy. Also read the Bitcoin Mixer and BTC Tumbler guides.
General Questions
What is Flash Mixer?
Flash Mixer is a Bitcoin exchange service with delayed private payouts and no registration. You specify up to 2 Bitcoin addresses to receive funds, choose a pool and fee tier, and optionally set a delay. Settlement is made from our liquidity reserves.
Is registration or personal information required?
No. Flash Mixer requires no registration. No email, no identity verification, no personal data. You only need a Bitcoin address for your payout.
How long is an order valid after creation?
Each order is valid for 45 minutes from creation. If payment is not received within this period, the order automatically expires and is cancelled. You can always create a new order.
How many Bitcoin confirmations are required?
3 blockchain confirmations are required to begin processing. This usually takes 30–60 minutes depending on network congestion.
What if I send less than the required amount?
Payments below the required amount are considered final. No additional funds are requested and partial refunds are not issued. Send the exact amount shown on the order page.
What if I accidentally send more than required?
Overpayment is not refunded and is considered a voluntary contribution. Double-check the amount before sending.
Do you support cryptocurrencies other than Bitcoin?
Currently only Bitcoin (BTC) is supported. Payout addresses must be valid Bitcoin mainnet 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, fee 1.5–10.0% + $20.0 fixed, delay 0–72h. Premium pool: 0.01–450.0 BTC, fee 3.0–10.0% + $20.0 fixed, delay 2–72h. Premium payouts are made from freshly allocated outputs with zero history. Standard payouts use diversified reserves.
Website
How do I create an order on the website?
Go to the Create Order page. Select a pool (Standard or Premium), set the fee percent, enter a Bitcoin address and receive amount, optionally add a second address and delay. The real-time calculator shows the total amount to send. Confirm — 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 to receive; the system automatically calculates the total amount to send including fees.
Can I split a payout across multiple addresses?
Yes. Each order supports up to 2 payout addresses. Each address can have its own amount and delay — for example, one immediate payout and one scheduled 12 hours later.
How do I check order status?
On the order status page (link provided after creation) you can see real-time confirmation progress, payout schedule, and transaction hashes once available. Bookmark the page or save the order UUID to access it via the Check Status page.
What is the API key on my order status page?
After your payment reaches 3 blockchain confirmations, you receive a one-time API key. It grants access to increased daily order limits via the programmatic API. The key is shown exactly once — save it immediately. It is never stored in plaintext on our side.
Is there a Tor (.onion) version of the site?
Yes. The Tor hidden service mirrors all mixer functionality and works entirely without JavaScript — all actions (create order, check status, PGP warranty verification) work in Tor Browser with scripts blocked via NoScript. Tor Browser access is available for network-level privacy; prefer Tor on sensitive networks.
Telegram Bot
How do I start using the Telegram bot?
Find @flashmixer_bot on Telegram and send /start. The bot will show a menu to create a new order or check an existing one.
Which languages does the Telegram bot support?
The bot supports English, Russian, Chinese, Spanish, German, and French, detected automatically from your Telegram settings.
How does the Telegram bot differ from the website?
Both channels 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 order status via Telegram?
Tap Check Status in the bot menu and enter your order UUID. The bot will show the current status, confirmation count, and payout details.
MCP Server
What is the MCP server?
The MCP server (Model Context Protocol) allows AI agents to interact with Flash Mixer programmatically. It provides five tools: create order, check status, pool configuration, fee calculation, and manual payment verification.
Who is the MCP server for?
Developers and AI systems that need to create or track 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 order by UUID
- get_pool_configuration — get limits, fees, and BTC/USD rate
- calculate_exchange_fees — calculate exact fees before creating an order
- trigger_payment_check — manually trigger payment check for an order
How do I connect an AI agent to the MCP server?
Configure your MCP client with endpoint . Set header Authorization: "Bearer <your-token>". The server uses HTTP Streamable transport with JSON-RPC 2.0 — compatible with any standard MCP client.
