Standard or read-only. Which one.

There is no lesser edition.

One generation engine, audited once, in every SOLANAkeystick we ship. Nothing about how your key is born is held back for a higher price — the difference buys a property of the object, never a better key. What is identical across every edition:

• The same entropy path — randomness drawn from the hardware at our own boundary, checked at runtime, blended with your own dice rolls. If the source fails its checks, every edition refuses to generate and says so loudly.
• The same standards — BIP-39 phrases, BIP-32 and SLIP-0010 derivation. Your phrase restores in any conformant wallet ever made.
• The same chains — receive addresses for Solana, and for Bitcoin and every EVM chain, shown once at the ceremony. One phrase covers all of them.
• The same unlimited use — the stick holds code, never keys. Every ceremony draws fresh randomness.
• The same sealed delivery — stick and card in one tamper-evident bag, inside a plain unbranded mailer.
• The same independent audit — every edition runs the same code, independently reviewed before we ship.

The difference: what happens in the drawer.

Your SOLANAkeystick never stores a key. So the risk it carries between ceremonies is not theft. It is substitution. The stick sits in a drawer for years; at some point you plug it into a computer that is already running. If that machine is infected, software on it can rewrite what is on the stick — and the next time you use it, you boot a ceremony that looks exactly like ours and produces a key somebody else can predict.

On the standard edition you close that gap yourself, by keeping the stick away from any running computer between ceremonies. Done carefully, that works. The read-only edition closes it with a physical switch: with the switch set, the drive refuses writes, so software on the host has nothing to write through. It turns a threat you meet constantly — an infected computer — into one that is rare: a person with your stick in their hand.

With the standard stick, integrity is a ritual you repeat. With the read-only stick, it is a fact that persists.

The editions, side by side.

Standard and for Mac are the same physical stick, as are the two read-only editions. You are choosing one thing: switch, or no switch.

Our recommendation: buy the read-only edition.

The standard stick is safe when used as directed. The trouble is that "as directed" is a rule you have to keep for as long as you hold the key — and the reason you generate offline is that you do not want your future self's memory to be load-bearing. Fifteen dollars turns a rule you must remember into a property of the object. Choose read-only if you expect more than one ceremony, you are generating for family or a business, or the balance is large enough that you would rather it not depend on your own discipline.

What read-only does not do.

• It stops software, not people. Anyone holding the stick can move the slider — which is also what makes new releases possible. It does not make the stick safe from someone who has it in their hand.
• It does not protect the ceremony. Your key is still born on your hardware. If the machine has a hardware implant, or a camera sees the screen, the switch is beside the point.
• It does not replace the seal. What proves the stick was ours is the tamper-evident bag it arrived in. Check it, on either edition.
• It is a claim we test. Every read-only stick has the switch set and a write attempted against it before the bag is sealed. If it does not refuse, it does not ship.
• It cannot recover anything. Neither edition can, and neither can we. If you lose your phrase the funds are gone.
