Today is November 5th, 2025. I’ve been actively using FixedFloat (ff.io) for about a year now, and I wanted to share my detailed experience. As someone who frequently swaps between various cryptocurrencies, I’ve tested quite a few exchanges, and FixedFloat has consistently impressed me with its speed, security, and, importantly, its fixed-rate swaps.
What is FixedFloat and Why I Started Using It?
For those unfamiliar, FixedFloat is a non-custodial cryptocurrency exchange. This means I retain control of my funds throughout the entire process. I didn’t have to deposit anything into an account; I simply initiated a swap, sent the crypto from my wallet, and received the exchanged crypto to another address I specified. I initially started using FixedFloat because I was tired of the fluctuating rates on other exchanges. I needed predictability, especially when dealing with larger amounts. The promise of a fixed rate, even with the included fees, was very appealing.
The Fixed vs. Float Rate Dilemma
FixedFloat offers both fixed and float rates. I primarily stick to the fixed rates. I found that while the float rates can sometimes be slightly better, the risk of the rate changing mid-transaction is too high for my comfort. I once tried a float rate on another exchange and the price slipped significantly while the transaction was processing, costing me a noticeable amount. With FixedFloat’s fixed rate, I know exactly what I’m getting, and that peace of mind is worth a small premium.
My Experience with the Platform
The platform itself is incredibly straightforward. I usually access it through their website (ff.io); The interface is clean and easy to navigate. I select the cryptocurrency I want to exchange, the cryptocurrency I want to receive, and the amount. FixedFloat then displays the fixed rate, the estimated amount I’ll receive after fees, and a transaction ID. I always double-check the receiving address before confirming – a crucial step with any crypto exchange!
I’ve swapped between Bitcoin, Ethereum, Litecoin, Dogecoin, and several other altcoins using FixedFloat. The transactions have always been remarkably fast. Typically, I receive the exchanged crypto within 5-15 minutes, which is significantly faster than many other exchanges I’ve used. I’ve never experienced any issues with failed transactions.
Security and Anonymity
Security is paramount when dealing with cryptocurrency. FixedFloat’s non-custodial nature is a huge plus in this regard. I never have to trust them with my funds. They also emphasize their military-grade security measures, which, while I can’t independently verify, gives me confidence. I also appreciate that FixedFloat doesn’t require KYC (Know Your Customer) verification for most transactions, offering a degree of anonymity.
Using the API (A Brief Dive)
I’m a bit of a tech enthusiast, so I also explored FixedFloat’s API. I’m primarily a Python developer, and I was pleased to find a Python library available. I used it to automate some of my smaller, more frequent swaps. The documentation was reasonably clear, and I was able to get a basic script up and running fairly quickly. I did have to generate an API secret and use HMAC SHA256 for signing requests, which is standard practice for secure API interactions. It’s definitely geared towards developers, but it’s a powerful tool for those who want to integrate FixedFloat into their own applications.
Here’s a very simplified example of how I used the Python library (Jobians/FixedFloatApi-Python):
from fixedfloat.fixedfloat import FixedFloat
api = FixedFloat("YOUR_API_KEY") # Replace with your actual API key
try:
order = api.create_order(
from_currency="BTC",
to_currency="ETH",
from_amount=0.01
)
print(f"Order created successfully! Transaction ID: {order['transaction_id']}")
except Exception as e:
print(f"Error creating order: {e}")
Fees and Rate Formation
FixedFloat’s fees are included in the rate you see upfront. I found this transparency very refreshing. I did some calculations and compared the effective fees to other exchanges, and they are generally competitive. The rate is formed based on the current market conditions and the fees required to process the transaction. I always pay attention to the estimated amount I’ll receive to ensure it meets my expectations.
