Frequently Asked Questions

What is a seed recovery phrase ?

When you generate a crypto wallet, you are typically asked to write down a list of 12 or 24 words, also known as the seed, recovery phrase, or mnemonic. In case your wallet device gets stolen or becomes unusable, this list of words allows you to re-gain access to your digital funds.

The words used in the recovery phrase are selected from a list of 2048 English words. The BIP39 list has the feature that each word can be uniquely identified by its first four letters. As a result, instead of backing up each word as a whole, it is sufficient to back up the first four letters only (three letters for three letter words).


CRYPTOETCH is a metal cold storage solution for your crypto assets. The CRYPTOETCH Kit supplies all the ingredients you need to etch your seed recovery phrase into steel and protect it against fire and water.


The CRYPTOETCH Kit is the cheapest and most flexible solution to immortalize your wallet recovery phrases on steel. CRYPTOETCH is free form and allows you to engrave whatever you want.

We are particularly proud that the CRYPTOETCH Kit was announced test winner in one of Lopp’s famous cold storage stress test. Check it out here:

What is etching ?

Etching is the process of using acid to cut into unprotected parts of a metal surface to create individual designs. Since the Middle Ages, goldsmiths, metal-workers and artists applied etching in order to decorate metal items such as guns, cups or plates.

In etching, the metal plate is covered with an acid resistant material such as varnish. The lines to be etched are cut into the varnish by means of an engraving tip, revealing the plate underneath. The plate is then exposed to acid that “bites” into the unprotected metal leaving behind lines sunk into the plate.

Instead of dealing with potentially dangerous acids directly, the CRYPTOETCH Kit provides you with harmless ingredients including salt water solution and a battery to “burn” your letters into the metal by way of a chemical reaction.

Do I need additional equipment ?

Everything you need for the etching process is included in the package.

Please note that due to legal provisions the shipping of acetone is restricted. In that case you will just receive an empty bottle which you can fill for easier dosage.

This is not a problem as you don’t need it for the etching process. The acetone is only used to remove the varnish at the end. You can use any nail varnish remover instead which is available in any drug store.

What plate sizes / shapes are available ?

The default plate size is 85x50x5mm (the size of a credit card). We do not offer additional plate sizes at the moment

How many words can I store on one plate ?

The default plate CE Master (85x50x5mm) allows you to store 2-4x24 word word recovery phrases (1-2 on each side). This is significantly more than competitive offerings at a fraction of the price. Choose wisely ;-)

Note: it is sufficient to store the first four letters of each word (e.g., “Access” -> “ACCE”, “Winner” -> “WINN”) as they uniquely identify each seed word.

How much does it cost ?

The CRYPTOETCH Kit costs CHF 40 + CHF 10 standard shipping and allows you to store 2-4 x 24 seed recovery phrases.

Please note that shipping outside of the EU (e.g., US, Canada, South America, UK, Australia, New Zealand, etc.) is typically more expensive than the default rate of CHF 10. In those instances, please add the worldwide shipping item (CHF 12) to your basket.

Add the tracking number to your basket if you want to track your package (

Can I pay in crypto ?

Yes, please get in touch with us via email ( or by using the form below. If you decide to pay us in fiat, we will convert most of it back into crypto. This is our contribution to building the crypto economy.

Where do I enter my shipping address ?

Stripe checkout does currently not support separate shipping addresses. If your shipping address is not the same as the billing address, please write us an email (

Do you ship outside of Switzerland ?

Yes, we ship globally. Please note that shipping outside of the EU (e.g., US, Canada, South America, UK, Australia, New Zealand, etc.) is typically more expensive than the default rate of CHF 10. In those instances, please add the worldwide shipping item (CHF 12) to your basket.

Do you offer a tracking number ?

Not by default. If you wish to have one for your package, please add the tracking number item to your basket.

Can I order additional plates ?

Yes. Please get in touch with us via email ( or use the form below.

Please note that additional plates will increase the weight of the package and hence shipping will be more expensive than the default shipping rate of 10 CHF.

Can I order customized sizes/shapes?

Unfortunataley, we do not offer additional plate sizes / shapes at this stage.

How can I protect myself against loss or theft ?

Backing up your seed recovery phrases on metal will protect you against fire and water but not against loss or theft. To protect your crypto funds in case of loss or theft you should encrypt your keys using the technique that we describe in one of our publications:

The fact that you can protect your assets even in the case of loss or theft by means of simple encryption is just another example why digital assets are superior to physical assets like gold or silver.
