The SafePal app works on its own, with no device bought: the key then sits in the phone's memory, and the vendor calls that mode suitable for everyday and small amounts. The device is added to that same app and takes over keeping the key and signing.
How the models differ
The S1 and the S1 Pro have no Bluetooth, no Wi-Fi and no NFC, and the cable in the box is only there for charging: data travels between the phone and the device solely as QR codes through the camera. Signing looks like this — the app shows a code with the unsigned transaction, the device scans it, you enter the PIN, the device gives back a set of codes with the signature, the app sends the transaction to the network. On the X1 the scheme is the same, only over Bluetooth. The other side of it the vendor admits itself: a fully offline device does not see that the balance has changed.
A swap and a transfer between networks cost 0.2%
The rate is one and the same for both operations: for a swap between different tokens and for a transfer of the same token between networks — USDT from TRC20 to BEP20, say — the vendor's help pages as of 19.09.2026 name 0.2% of the order. There is no separate raised fee for cross-chain, the widespread claim notwithstanding. The “0 fee” promise from the vendor's blog of 2020 contradicts the help pages in force — 0.2% is the figure to go by. Buying crypto for fiat, on the other hand, is also an exchange inside the app, but its fee the vendor publishes nowhere, and the 0.2% cannot be carried over to it.
On top of the 0.2% come the network fee and the rate of the outside exchange provider: both items the vendor excludes from its own rate in plain words, and the size of the provider's rate it does not disclose. Slippage is shown on a separate screen before signing. How long a swap takes the vendor puts, on that same date, at 15–30 minutes.
EAL6+ — but whose certificate it is goes unsaid
The line “CC EAL6+ Chip” stands only in the model comparison table; on the page of the model itself the wording is different — “EAL6+ independent secure element” on the X1 and simply “EAL6+” on the S1 and the S1 Pro. The wording “EAL5+”, which goes round the reviews, the vendor gives nowhere. At the same time neither the chip maker, nor the certificate number, nor the certifying body is named — the reader cannot check the certificate against a document, and it is better to know that beforehand.
