Scope of this review
This review concerns swaptozec.com. Its published material describes an exchange-style service rather than an account-based wallet: a customer supplies a destination address, sends assets to an address provided for an order, and receives the output at the address entered. That operational model makes the transfer details central.
Non-custodial does not mean risk-free
A blockchain transfer can be difficult or impossible to reverse. A wrong network, destination address, refund address, or order detail can therefore matter more than a polished interface. Before submitting an order, check the asset, network, quoted amount, fees, minimums, refund path, and the time at which a rate can change.
Know the company and complaint route
For a larger transaction, identify the legal operator, operating jurisdiction, terms, privacy policy, and practical support route before funds leave your wallet. A service can be non-custodial while still collecting transaction and contact information or setting conditions for a refund. Make sure you know which party would answer a dispute.
What you should check before you act
Use a small, fully understood transaction only if the documented terms and exact payment addresses have been independently verified. Never share a seed phrase or private key. Keep the order identifier, transaction hash, destination address, and current terms for your records.
