StealthEX lets you swap crypto-to-crypto without creating an account for the vast majority of trades — but that changes the moment you route fiat through its card on-ramp above a few hundred euros. This review breaks down what StealthEX actually charges (a spread-based service fee, not a flat line item), how its min/max limits scale by coin, when its automated compliance checks kick in, and what its Trustpilot record says about fund-hold complaints versus praise for execution speed. Whether you’re using StealthEX directly or via an aggregator like SwapZilla, here’s what to check before you commit a deposit.
What StealthEX actually is
StealthEX launched in 2018 as a non-custodial instant-exchange: you send crypto, it routes the trade through its own liquidity relationships, and sends back the destination asset — no persistent balance, no order book, no account required to place a trade. That’s a different model from a spot exchange like Kraken or Coinbase, where you deposit funds into a custodial account and trade against an order book.
Corporate registration is one area where public sources don’t fully agree — most listings point to the Marshall Islands, while a handful describe a different offshore jurisdiction. Either way, StealthEX doesn’t hold a license from a major regulator like the FCA or FinCEN, which is standard for instant-exchanges of this type rather than a red flag specific to StealthEX.
Because it’s non-custodial by design, StealthEX also plugs cleanly into aggregators. Route through SwapZilla and StealthEX becomes one quote among several on the same screen, so you can compare its spread against other providers before committing — instead of checking StealthEX’s site, then a competitor’s, then a third, separately.
StealthEX is an exchange, not an aggregator. It sources its own liquidity and settles the trade itself — routing through a service like SwapZilla just adds a side-by-side rate comparison on top.
Fees — what you’re actually paying
StealthEX doesn’t show a separate “fee” line at checkout. Instead, its service fee is baked into the quoted exchange rate: roughly 0.4% on floating-rate swaps. Fixed-rate swaps carry a somewhat wider spread, since the extra margin covers the price-lock risk StealthEX takes on for a short price-lock window (typically around 10–30 minutes, varies). Network fees for the destination chain are estimated and folded into the final amount you see before confirming, so the number displayed is meant to be the actual amount you receive.
The practical takeaway: don’t compare StealthEX to a competitor by fee percentage alone — compare the final quoted amount for the same pair and size, since that already nets out both the service fee and the estimated network cost. Rates also drift with market volatility between the moment you get a quote and the moment your deposit confirms, which is exactly where the floating-vs-fixed choice matters.
For exact current numbers, check StealthEX’s own fee and limits page — spreads move with market conditions and shouldn’t be treated as fixed indefinitely.
Limits — min and max per swap
There’s no universal cap. On floating-rate swaps, StealthEX doesn’t publish a maximum — you can move large amounts, and the constraint becomes liquidity depth on the specific pair rather than a platform rule.
Minimums are a different story, and they vary per coin, driven mostly by keeping the swap value comfortably above the destination network’s transaction fee. Typical ranges look like this:
| Coin | Typical minimum swap (approx.) | Maximum |
|---|---|---|
| BTC | ~$15–30 equivalent | No cap (floating) |
| ETH | ~$10–20 equivalent | No cap (floating) |
| SOL | ~$5–15 equivalent | No cap (floating) |
| XMR | ~$15–30 equivalent | No cap (floating) |
| USDT (TRC-20) | ~$10–20 equivalent | No cap (floating) |
These are illustrative ranges, not locked numbers — StealthEX recalculates the exact minimum live, based on current network fees, and shows it before you confirm a swap. Fixed-rate swaps sometimes carry a lower practical ceiling than floating, since StealthEX has to hedge the short price-lock window against its own liquidity.
Coins and networks supported
StealthEX lists over 2,000 assets, a number that keeps climbing as it adds new wallet and blockchain integrations. For privacy-focused users, the one that matters most is XMR — Monero support puts StealthEX (and aggregators that route through it, including SwapZilla) in a fairly short list of instant-exchanges still listing the coin after several centralized platforms delisted it under exchange-level pressure.
Breadth is only useful if you pick the right network. Several assets on StealthEX exist across multiple chains — USDT alone shows up as native, TRC-20, ERC-20, and other variants — and sending to the wrong network variant is one of the most common ways a swap gets stuck. Always match the network shown in the deposit instructions to the network your sending wallet is actually using, not just the coin ticker.
Verification policy — when StealthEX actually asks for ID
For a typical crypto-to-crypto swap, StealthEX doesn’t ask for identity verification — there’s no account to register, and the trade completes without a name, email, or document attached on StealthEX’s side. That’s the core of its “no account” pitch, and for straightforward BTC-to-XMR or ETH-to-SOL swaps at normal sizes, it holds up.
It changes on two fronts. First, StealthEX’s fiat-to-crypto on-ramp (via a card-payment partner) applies identity checks above a threshold in the low hundreds of euros — sources put it around €700–900, and it can shift, so treat it as a ballpark rather than a fixed line. Second, StealthEX runs automated AML screening on the crypto side too: a wallet flagged by chain-analysis tooling, or an unusually large single swap, can trigger a request for source-of-funds documentation regardless of whether you touched the fiat on-ramp at all.
“No verification” and “no verification, ever” are different claims. StealthEX skips identity checks for most crypto-to-crypto trades, but its automated compliance system can still flag a specific wallet or amount — read that as “verification triggers above a threshold,” not a blanket exemption.

Security and reputation — the balanced view
Because StealthEX is non-custodial, it isn’t sitting on a large hot-wallet balance the way a centralized exchange does — funds pass through in the time it takes to execute a swap rather than resting in a StealthEX-controlled account. That reduces, but doesn’t eliminate, the attack surface associated with large custodial breaches. No independently documented hack or systems breach of StealthEX turns up in public records as of this review — but the absence of a reported incident isn’t the same as a guarantee, and any service you’re sending funds to deserves that caveat.
Trustpilot paints a mixed but broadly positive picture: StealthEX sits around 4.0 out of 5 across roughly 440 reviews at last check. The praise clusters around execution speed and support responsiveness on straightforward privacy-motivated swaps. The complaints cluster around a specific pattern: funds held pending compliance escalation — source-of-funds requests, extended verification back-and-forth — with a handful of reviewers describing slow resolution. StealthEX’s public responses attribute these holds to standard AML procedures required by its liquidity partners rather than discretionary account freezes.
Read both sides before moving a size you’d be uncomfortable having tied up for days if a hold gets triggered.
Verdict — who StealthEX fits, and how routing through SwapZilla changes it
StealthEX is a solid fit if you want a straightforward crypto-to-crypto swap without creating an account, especially if XMR is part of the trade — it’s one of the more consistent Monero-supporting instant-exchanges still standing. For typical retail sizes, the fee spread is competitive and the flow is fast.
It’s a weaker fit if you’re planning to route a large single swap and can’t tolerate the possibility of a compliance hold, or if you specifically need a fiat on-ramp above a few hundred euros without any identity step.
Using StealthEX through SwapZilla doesn’t change how StealthEX itself executes or verifies a trade — that logic lives entirely on StealthEX’s side. What changes is visibility: instead of taking StealthEX’s quote on faith, you see it next to every other provider we route through, for the same pair and amount, before you commit. If StealthEX’s spread is off on a given day, you’ll see a better one instead of finding out afterward.
