The biggest threat to writing your wallet recovery seed on paper is not necessarily from a house fire or flooding but from:
- What your seed was written on
- What was it written with, and
- How it was stored
What possibly can happen to a piece of paper?
Two types of deterioration can occur:
- Fading and discoloration can occur caused by exposure to light or ultraviolet (UV) radiation making your seed illegible
- Mold can develop if stored in humid conditions and can consume and/or discolor the paper
- Acid present either in the paper or other items the paper is in contact with (such as a storage container or other paper) can result in brittleness and staining of the paper.
- Acid present in ink used to write your seed can also cause deterioration
- Damage caused be handling such as tears, dents, punctures, abrasions, folds, creases, rubbing, etc. can damage the paper or smear the writing to be illegible
- Pests (such as insects or rodents) where paper is a food source can consume your seed
- Temperature and humidity fluctuations can cause deterioration of the paper's structural integrity and result in higher susceptibility to damage.
Okay, what can I do to avoid this deterioration?
That begins before you even write your seed. Take the following tips in consideration:
- Have clean hands when writing your seed or handling the paper your seed is on
- Use acid-free, lignin free paper (and avoid colored paper)
- Use a graphite pencil (preferably #3), not ink, to write your seed. (Inks can contain acid that deteriorate the paper)
- Record your seed on paper that is on a clean, hard surface, to avoid embossing the characters into the paper.
- Create multiple copies of your seed.
- This increases the risk of of being found by a third party but redundancy prevents having a single point of failure and promotes longevity of data.
- Place your document between two sheets of acid-free plastic.
- This process is called encapsulation: documents are sandwiched between stable, archival plastic sheets and sealed around the document by static electricity. Nothing is directly attached to the document or melted to the document during this process.
- Contrary to popular belief, do not laminate your seed:
- The heat and pressure during lamination damages the structural integrity of the paper.
- The plastics used in lamination is typically cellulose acetate which is inherently unstable and will deteriorate further damaging the paper. (That is why archival documents seen in museums and libraries are never laminated.)
- Store in a clean, dark, dry cool area (room temperature or below)
- Avoid unstable environments where temperature fluctuations, humidity, and risk of leaks are present (such as an attic, garage, or basement)
- Store away from radiators and vents
- Do not store it in a basement or attic
- Use supportive protective enclosures that can create a micro environment to avoid the full effects of fluctuating humidity and temperature.
- Store in a sealable, waterproof container of acid free material.
- Utilize a fire-proof safe
- Store above waist height to minimize damage from floods
- Do not store your seed with other items or materials.
