Reasonable rates and a long asset list, held back by thin support when a transaction goes sideways.

The short answer

StealthEX prices better than most of the mid-tier, supports a long tail of tokens without an account, and clearly separates fixed from floating quotes. Its weakness is support: when a transaction stalls, replies are slow and generic, which is exactly when a service needs to perform.

Usable, but there are better options for most people. The headline 6.7 is the weighted mean of these marks — see our methodology. Not financial advice.

What we liked

  • Competitive floating rates and hundreds of supported assets
  • No registration for standard swaps
  • Clear separation between fixed and floating quotes

Where it falls short

  • Support is slow and largely templated
  • Compliance holds follow the category norm

StealthEX occupies a useful position: rates closer to the transparent leaders than to the expensive incumbents, with coverage approaching the aggregators. For routine swaps it is one of the better-value direct services.

Pricing and coverage

Floating rates carry a margin of roughly 0.4%, with fixed rates priced higher, across several hundred assets and all major chains. The interface makes the rate type explicit, which matters more than it sounds — services that blur the distinction leave users surprised when the amount received differs from the quote.

Support is the weak point

User reports consistently describe slow, templated responses to stuck transactions, with limited ability to escalate. Since the entire value proposition of an instant exchanger rests on the transaction completing, a service that cannot help when it does not is failing at its core function even if the rates are good.

Custody and compliance

Standard for the category: funds are held between legs, screening applies, and a flagged deposit can be frozen pending documentation. StealthEX does not stand out in either direction on hold frequency.

Who should use StealthEX

Price-conscious users making routine swaps of modest size who are comfortable with limited support. For anything where a stall would be a serious problem, use a service with responsive support or an exchange with a redress process.

FAQ

What are StealthEX's fees?
Roughly 0.4% embedded in floating-rate quotes, with a premium on fixed rates — competitive for the mid-tier.
Is StealthEX anonymous?
No account is required for standard swaps, but compliance screening applies and flagged transactions require identification before release.
How is StealthEX support?
Slow and templated. Users report difficulty escalating stuck transactions, which is the service's main weakness.
Is StealthEX safe?
It has run since 2018 without a major breach. The custody-during-swap and compliance-hold risks common to the category still apply.
