How to exchange cryptocurrency on FixedFloat
FixedFloat (also known as fix float, ffio, FF or fixed float crypto) gives you one of the simplest crypto-to-crypto exchange flows on the market. The widget at the top of this page is the same engine that has powered millions of swaps on the FF platform — only the domain has changed to ff-io.io. Here is exactly how to use it.
Step 1 — pick the right currency pair
Click the You send coin selector and pick the asset you currently hold. Then pick the asset you want to receive in You get. The FF platform automatically pulls the live aggregated rate from multiple liquidity sources and shows the expected output amount. Pairs that are temporarily out of stock will be greyed out — the system never lets you create an order that cannot be filled.
Step 2 — choose fixed or float rate
The fixedfloat exchange offers two modes:
- Fixed rate. The price is locked the moment you confirm. You will receive exactly the amount displayed regardless of how the market moves during the transaction. The fixed-rate mode includes a small spread to compensate the platform for taking on volatility risk on your behalf — a fair trade for predictable invoices and fast settlement on slow chains.
- Float rate. The output is recalculated at payout time using the current market price. If the market moves in your favour, you get more; if it moves against you, slightly less. Float is ideal for fast-confirming chains where the on-chain delay is short.
Step 3 — paste your destination address
Enter the wallet address that will receive the output coin. The widget runs format validation locally — it checks the address checksum and warns you if a memo or destination tag is required (relevant for XRP, XLM, EOS and certain exchange-hosted addresses). Always double-check the address before pressing Create exchange; once a transaction is broadcast on a public blockchain, it cannot be reversed.
Step 4 — send your deposit
FixedFloat will display a one-time deposit address and the exact amount it expects. Send the funds from your own wallet — never from another exchange withdrawal whose return address you do not control, because in case of any issue the FF platform may need to refund you. The system tracks the mempool live; you will see status updates the moment the network sees your transaction.
Step 5 — receive the output
After the agreed number of confirmations, the FixedFloat exchange hot wallet broadcasts the outgoing transaction. The order page provides the output transaction ID so you can independently verify it on a block explorer. For most pairs, the entire end-to-end process takes between five and thirty minutes.
Tips for a smooth ff-io.io exchange
- Match the network. When sending USDT, make sure the chain you select on FixedFloat matches the chain your wallet uses (TRC-20, ERC-20 or BEP-20). Choosing the wrong network is the most common cause of stuck transactions.
- Use the recommended fee. A deposit with a too-low miner fee may take hours; the FF platform will still process it, but you will wait longer.
- Consider float rate for fast pairs. ETH ↔ USDT or LTC ↔ ETH typically benefit from float execution.
- Use fixed rate for invoices. When a third party expects an exact amount, fixed rate guarantees you deliver it.
- Save the order ID. Every fixedfloat exchange order has a unique ID — keep it in case you need 24/7 support.
Frequently asked questions about exchanging on FF
Do I need an account to exchange on ff-io.io?
No. Standard pairs require zero registration. Some advanced features such as the affiliate dashboard and the API rely on an optional account.
What is the minimum amount I can exchange?
Each currency has a small minimum that covers the network fee. The widget shows it in real time — usually about $5–$15 worth of crypto.
What happens if the rate changes during my BTC transfer?
If you chose fixed rate, you receive the locked amount no matter what. If you chose float, the engine recalculates at payout time. Either way, FF never adds hidden spreads after order creation.
