Fixed Rate vs Floating Rate — Which Should You Pick?

3 min read

Every swap on ff.io gives you two choices: fixed or floating. A fixed rate locks the price the moment you create the order — what you see is exactly what you get, regardless of market swings during confirmation. A floating rate follows the market; the final amount is determined when your deposit hits the required confirmations.

Use fixed when you need certainty — for example, paying an invoice for an exact amount. Use floating when you think the market might move in your favor and want to capture that upside. Both options are fully non-custodial and settle within minutes.

Pro tip: for large amounts during high volatility, fixed rate removes the stress of watching charts while you wait for block confirmations.

How to Buy Monero (XMR) Without KYC in 2026

4 min read

Monero is the top privacy coin — but most centralized exchanges now demand full identity verification to let you buy it. That defeats the purpose. With ff.io you can swap BTC, ETH, USDC or dozens of other coins directly into XMR with no registration whatsoever.

The process is simple: go to ff.io, select your source coin (e.g. USDC on Ethereum), choose XMR as the destination, paste your Monero wallet address, and send. The swap engine handles everything automatically. There's no account to create, no email to verify, and no documents to upload.

Because ff.io is non-custodial, your funds are never sitting on a centralized server waiting to be hacked. They go from your wallet, through the swap, and straight into your Monero wallet — usually within a few minutes.

Lightning Network & Layer 2 Swaps Explained

4 min read

On-chain Bitcoin transactions can take 10–60 minutes and cost several dollars in fees. The Lightning Network changes that: BTC transfers settle in seconds with fees measured in fractions of a cent. ff.io fully supports Lightning for both deposits and withdrawals.

Beyond Lightning, ff.io bridges tokens across Layer 2 networks like Arbitrum, Optimism, and Base — plus chains like Solana, Tron (TRC20), and BNB Chain. Need to move USDT from Tron to Ethereum? Or swap SOL for BTC on Lightning? It's all a single step on ff.io.

This is especially useful for DeFi users who frequently move assets between ecosystems. Instead of using multiple bridges with different interfaces and risks, you get one clean swap interface that handles the routing for you.

How long does a swap take?
Most swaps complete in 2–15 minutes depending on the blockchain's confirmation time. Lightning Network transactions are nearly instant.
What's the difference between fixed and floating rate?
Fixed rate locks the exchange rate when you create the order. Floating rate gives you the market rate at the time your transaction confirms. Fixed offers certainty; floating can sometimes give you more if the market moves in your favor.
