SimpleSwap Review

What stood out when we checked SimpleSwap

When we opened SimpleSwap, we spent more time on the exchange screen than on the homepage. The BTC to ETH flow was direct: choose the coin to send, choose the coin to receive, enter the recipient Ethereum address, add a refund address if you want one, and continue. That is useful. It also puts real responsibility on the user. A clean screen does not fix a wrong address.

Our view: SimpleSwap is worth checking for wallet-to-wallet swaps, but fiat buy routes need provider comparison before you pay.

The floating rate was visible from the start — not buried in settings. The refund address field was there too, easy to skip. Worth filling in. If a swap cannot complete and no refund address is set, recovery becomes harder and support-dependent.

The Buy tab was a different picture from what the homepage suggests about SimpleSwap being crypto-only. It showed fiat-to-crypto routes via payment providers — EUR to BTC with Visa, Mastercard and Apple Pay logos visible. When we opened the provider offer screen for 300 EUR, the final BTC amount was not the same across all routes. The gap between the best and lowest offer was roughly 2.6%. We would compare that number first, not the provider name.

There was also a Sell tab, a promo code visible in our affiliate account materials, and a loyalty program with fee discounts and cashback. SimpleSwap is running more than a basic swap interface. See our best crypto swap platforms comparison for a side-by-side view.

What we checked

We checked the exchange interface up to the address and rate step, the Buy tab on a EUR to BTC example, the Sell tab on a BTC to EUR example, the provider offer screen with 300 EUR as input, the promo code and loyalty materials, and the top pairs section. We did not complete a real exchange, did not send funds, did not test support speed, and did not measure processing time.

Quick facts

How SimpleSwap works in practice

The exchange flow is direct. Select the input asset — BTC in our check — select the output asset (ETH), enter the recipient Ethereum wallet address, and optionally add a refund address. The refund address field is easy to scroll past. It is worth filling in. If the swap cannot complete for any reason, the refund goes back to that address. Without one, recovery depends on support.

The interface is clean. That is fine for experienced users who already know to check the network. What the clean screen does not do: prompt you to verify that the Ethereum address you entered is actually for the Ethereum network, and not for a different chain that uses the same address format. That check is on you.

Buy crypto with fiat on SimpleSwap

The Buy tab showed a fiat-to-crypto route on the EUR to BTC example we checked. The rate shown was floating — no fixed rate option was visible for the fiat buy flow. Payment logos including Visa, Mastercard and Apple Pay appeared on the screen.

EUR to BTC on the Buy tab. Floating rate shown. Visa, Mastercard and Apple Pay logos visible. The final BTC amount depends on the provider route — compare the offer screen before choosing.

The first offer shown is not always the one with the best final amount. We opened the provider offer screen and found a meaningful gap between providers for the same 300 EUR input — more detail in the next section.

Buy offers, providers and payment methods

We opened the EUR to BTC offer detail screen with 300 EUR as the input. Multiple providers appeared with different final BTC amounts for the same input.

Provider offer screen from our check — 300 EUR to BTC. Five providers listed with different final BTC amounts. Topper was marked BEST RATE in this screen. The gap between the best and lowest quote was roughly 2.6% on this example.

Providers we saw in the offer list: Topper, Mercuryo, MoonPay, Sardine and Stripe.

Payment methods shown: Credit Card, Revolut Pay, Apple Pay, Debit Card, Google Pay, SEPA Bank Transfer, PayPal, Bank, Open Banking and SEPA Instant.

Final BTC output amounts visible in our check for 300 EUR input — approximate, as seen on screen at the time of our review, not current rates:

The practical point: for the same 300 EUR input, the final BTC amount varied by roughly 2.6% between the best and lowest provider in our check. That gap widens in real terms on larger amounts. A recognisable logo — Revolut, Apple Pay, PayPal — does not mean the best output. The final amount column is what matters. Provider availability, supported payment methods and any KYC requirements also differ by country and account status.

Sell crypto to fiat

The Sell tab showed a crypto-to-fiat route. We checked BTC to EUR. The floating rate was shown — the EUR payout estimate is visible on screen but not final until the provider confirms the route. Country, bank or card payout method, and any required identity verification can all affect what is actually available to you.

BTC to EUR on the Sell tab. Floating rate visible. The EUR payout estimate shown is not final — provider confirmation, route availability and verification requirements depend on your country and account status.

Sell routes work differently from buy routes. The payout goes to a bank account or card depending on the provider. Verification requirements for sell flows can be stricter than for crypto-to-crypto swaps.

SimpleSwap promo code and $50 USDT offer

While reviewing our SimpleSwap affiliate account materials, we saw a promo code connected to our account. The dashboard described a $50 USDT offer with these steps: sign up to SimpleSwap, complete a crypto exchange using the promo code, receive $50 in USDT in the customer account.

Promo code and $50 USDT offer as shown in our affiliate account at the time of review. Campaign status, eligibility and terms can change — not a guaranteed reward.

Promo code from our affiliate account: BuNTYynZF0DJXjS2

Eligibility depends on campaign rules, your country, account status, exchange amount and whether the campaign is still active when you use it. This offer is affiliate-linked — it comes from our account relationship with SimpleSwap. Check the current terms before using the code.

SimpleSwap loyalty program

SimpleSwap has a loyalty program visible in the interface. Based on what we saw, it offers a service fee discount of up to 20% and cashback of up to 0.4 USDT for finished swaps. Creating a SimpleSwap account moves you to Bronze level. The text we saw stated that once a loyalty level is reached, it does not expire.

The loyalty program is worth knowing about if you swap regularly. The fee discount compounds across many transactions. The cashback per swap is modest in absolute terms. Neither is the main reason to choose SimpleSwap — the rate on each swap still matters more — but they are a real extra for active users.

Popular pairs and asset coverage

SimpleSwap also showed a top-pairs screen with crypto-to-crypto and fiat-to-crypto examples such as ETH to SOL, BTC to ETH, BTC to USD and USDT MATIC to EUR. We would treat this as a sample of active routes, not as a full asset-coverage list. Check the platform directly for your specific asset and network. See our USDT networks guide for how network choice affects USDT transfers specifically.

SimpleSwap fixed rate vs floating rate

• Fixed rate: The rate shown when you start the swap is locked in. You know the output before sending. Fixed rates typically carry a slightly higher spread to account for locking in the rate.
• Floating rate: The rate follows the live market during processing. The final amount can be slightly more or less than the initial quote. Floating rates often have a lower spread.

For the fiat buy route we checked (EUR to BTC), only a floating rate was visible — no fixed rate option appeared for that flow. For crypto-to-crypto swaps, both options were available.

During volatile conditions or for larger amounts, the gap between a floating-rate quote and the actual output can be real money. If certainty over the output matters more than a slightly better rate, the fixed rate option is worth selecting when it is available.

Fees, rates and final received amount

SimpleSwap does not publish a separate stated fee for crypto-to-crypto swaps. The cost is embedded in the exchange rate — the output you receive is slightly lower than the mid-market rate. Network fees for sending the input asset come on top of that. Ethereum fees can be significant during congestion; Tron, Solana and BNB Chain fees are typically lower.

For fiat buy/sell routes, costs come from multiple sources: the swap spread, the payment provider's margin, and the payment network fee. The practical comparison is the final received amount on the offer screen — not the headline rate or the provider logo.

The 300 EUR to BTC example from our check showed roughly a 2.6% gap between the best and lowest provider quote. On 300 EUR that is a small nominal difference. On larger amounts it is worth the 30 seconds it takes to compare. The loyalty program's fee discount can reduce the swap spread for account holders on crypto-to-crypto swaps — but it does not change what payment providers charge on fiat routes.

KYC and account requirements

Basic crypto-to-crypto swaps do not require an account or identity verification. You provide a destination address, send the input asset, and receive the output. No email, no password, no profile needed.

The loyalty program and promo code require a SimpleSwap account. Fiat buy/sell routes involve third-party payment providers, and those providers apply their own checks based on amount, payment method and country. Even for crypto-to-crypto swaps, a compliance review can still appear for certain amounts, assets or jurisdictions. The accountless-looking flow does not mean no checks ever happen. See our crypto wallet mistakes guide for mistakes beginners make around KYC assumptions on swap platforms.

What if a SimpleSwap exchange is delayed?

We did not complete a real exchange, so we cannot speak to the support experience from personal testing. Based on user reports and the platform's own guidance, delayed swaps happen — and being prepared makes recovery easier.

Before closing the browser after initiating a swap, save: the exchange ID, the destination wallet address and network, the coin pair, the amount sent, the refund address you provided, and — for fiat routes — the payment route details. These are what support will ask for.

Common reasons for delays: network congestion on the input or output chain, a floating-rate shift that moved the output outside acceptable parameters, wrong network selected, a compliance or AML check triggered by the amount or asset. If a swap is stuck, contact support with the exchange ID rather than resending funds to the deposit address.

Recovery is not guaranteed. The refund address field on the exchange form exists precisely for these situations. Fill it in.

Before you use SimpleSwap

This is where we would slow down:

• Check the coin ticker — some coins share similar names or abbreviations across chains
• Check the network — USDT on Tron is not the same as USDT on Ethereum
• Check the recipient wallet address carefully before proceeding
• Add a refund address — do not leave it blank
• Compare the final output amount across providers for fiat routes, not just the rate percentage
• Understand that a floating rate can shift before the swap completes
• Read the promo code terms before counting on the reward
• Check loyalty program conditions if you plan to use the cashback
• Avoid rushing during market volatility — floating rates move faster when prices are moving

SimpleSwap alternatives

Changelly listed broad asset support at the time of review. The practical difference is that Changelly has fiat card buy and sell routes in more regions. For crypto-to-crypto swaps, compare the quoted rate on both at the time you want to swap — the better rate depends on the moment and the pair.

ChangeNOW listed broad pair support at the time of review and operates without registration for basic swaps. Neither has a loyalty program or promo in the same form. Rate comparison between SimpleSwap and ChangeNOW on your specific pair is the most useful check.

If you need to buy crypto with fiat regularly, or need order books and limit orders, a regulated exchange is a better fit than a swap platform. See our swap platforms comparison for a full side-by-side view.

Who SimpleSwap is for

• You hold crypto and want to swap between assets without creating a full exchange account
• You want broad coin selection among swap platforms and will verify the current pair before sending funds
• You swap regularly and want the loyalty fee discount to reduce costs over time
• You are comfortable checking wallet addresses, networks and final amounts before confirming

Who should avoid it

• You have not yet set up a self-custody wallet — understand addresses and networks before using any swap service
• You need to buy crypto with fiat regularly at low fees — a regulated exchange with a full account usually offers better fiat terms than provider routes through a swap platform
• You need order books, limit orders or advanced trading tools — a crypto exchange is the right product
• You want no-KYC on all routes as a certainty — fiat buy/sell flows involve provider checks, and even the crypto swap flow does not rule out compliance reviews

Our view after checking SimpleSwap

The exchange interface is clean and fast. For crypto-to-crypto swaps, SimpleSwap listed broad asset support at the time of review. The refund address field is a practical safety option that the clean interface makes easy to skip — it should not be skipped.

The fiat buy/sell routes are a real addition, but the provider offer comparison screen is where the useful information actually lives. A 2.6% gap between the best and lowest provider on a 300 EUR buy is worth the time it takes to open that screen. The first offer shown is not always the best one.

The promo code and loyalty program make SimpleSwap more than a plain swap utility. Neither is the reason to choose it over ChangeNOW or Changelly — but for users who plan to swap regularly, the loyalty fee discount has real long-term value. Check the rate on your specific pair before committing. See best crypto wallets if you need to set up a self-custody wallet before swapping.
