Instant swap exchanges are simple to use, but a handful of best practices will make your swaps safer, more private, and less likely to go wrong. This is a step-by-step guide to doing a swap from start to finish — choosing the coins, picking a rate type, entering your receiving and refund addresses, understanding confirmations and timing, and the privacy habits worth building from day one. The whole model is address-based: no account, no login, you just send and receive. If you're brand new to the concept, start with What is an Instant Swap Exchange?
Before you start: a quick checklist
- Have a self-custody wallet ready for the coin you want to receive (a wallet where you control the keys).
- Skim the service's terms and conditions — limits, restricted coins/regions, and what triggers any verification.
- Decide whether to use a VPN or Tor for privacy (and check the terms allow it).
- Know roughly how much you're swapping, so you stay within the service's minimum and maximum.
Step by step: how to do an instant swap
1. Choose the coin you're sending and the coin you're receiving
Pick your input (the coin you already have) and your output (the coin you want). Instant swaps are usually cross-chain, so you can go from, say, Bitcoin to Monero or Ethereum to Litecoin in one step. Enter the amount and the service will quote what you'll receive.
2. Pick a fixed or floating rate
Most services let you choose how the rate is set:
- Fixed rate: the amount you'll receive is locked when you start. Predictable, usually for a slightly higher fee — good when you want certainty or the market is volatile.
- Floating rate: the rate is finalized when your deposit confirms. Often cheaper, but it can move with the market while the transaction settles.
3. Enter your receiving wallet address
Paste the address of the wallet where you want the swapped coins delivered. Use a wallet you control — self-custody, not an address on a custodial exchange. Two things to triple-check:
- The address is correct (copy-paste, then verify the first and last characters).
- It's on the right network for that coin (e.g., a USDT address on the exact chain you selected).
Crypto transactions are irreversible, so an address mistake here means lost funds.
4. Set a refund address
Most services ask for a refund address — an address you control where funds are returned if the swap can't complete. Don't skip it. We cover why below, but in short: this is your safety net.
5. Send your deposit
The service generates a one-time deposit address (and sometimes a memo/tag for certain coins — include it if shown). Send the exact amount from your wallet. If you're using a wallet that needs to sync, let it finish syncing before you pay so it broadcasts cleanly.
6. Wait for confirmations, then receive
The swap begins once your deposit reaches the required number of network confirmations, then the service converts and pays out to your receiving address. You don't need to do anything during this — just wait.
How long does it take?
The number of confirmations needed before the swap starts varies by coin and service, and total time depends on network congestion. As rough estimates:
- Bitcoin: often 1–2 confirmations — roughly 10–30 minutes.
- Ethereum: a handful of blocks — usually a few minutes.
- Litecoin / others: typically a few minutes.
- Monero: around 10 confirmations — roughly 20 minutes.
After your deposit confirms, the conversion and payout usually complete within minutes. Treat these as ballpark figures, not guarantees.
The refund address: your safety net
A swap can occasionally fail to complete — for example if a floating rate moves outside the allowed range, if you send below the minimum or above the maximum, or if there's a network issue. When that happens, the service returns your funds to the refund address you provided. If you didn't set one (or set it wrong), getting your money back is slower and harder. Always set the refund address to a wallet you control, ideally for the same coin you're sending.
Best practices for privacy and safety
- Use self-custody wallets. Receive into a wallet whose keys you hold, not a custodial exchange address — it's safer and keeps the swap private.
- Use a fresh wallet/address for each swap. A brand-new receiving (and refund) address each time makes it much harder to link your swaps together, which meaningfully improves privacy.
- Read the terms and conditions. Check limits, supported coins and networks, any KYC/AML triggers, and which regions or behaviors are restricted.
- Use a VPN or Tor where allowed. These protect your network privacy — but confirm the service permits them, since a few restrict or flag certain traffic.
- Sync your wallet before paying if it requires syncing (common with Monero), so your balance and broadcast are current.
- Do a small test first with a new service before moving a large amount.
- Double-check everything — addresses, networks, memos/tags, and amounts. There's no undo button.
Putting it together: the framework
Every safe swap follows the same shape:
- Prepare a self-custody wallet and read the terms.
- Choose your send and receive coins, then a fixed or floating rate.
- Enter your receiving address (right coin, right network) and a refund address you control.
- Send the exact deposit to the one-time address, including any memo/tag.
- Wait for confirmations; receive your coins in self-custody.
- Use fresh addresses and VPN/Tor for privacy, and test small with new services.
