The Letters on Self-Custody

Chapter 1

On the meaning of “not your keys, not your coins.”

1. To every believer who has held coin upon an exchange, peace.
2. There is a saying among the faithful, and the saying is short, and it does not flatter:
3. Not your keys, not your coins.
4. The saying does not mean that the coins held by the exchange are stolen. They may not be. They may be held with care.
5. The saying does not mean that the exchange will fail. It may not. It may continue for many years.
6. The saying means: that which you hold by the keys of another is held by another.
7. The chain knows the keys. The chain does not know the names.
8. The chain pays the keys. The chain does not pay the names.
9. If the keys of the exchange are seized, your coins are seized. If the keys of the exchange are lost, your coins are lost. If the keys of the exchange are stolen, your coins are stolen.
10. You may have a paper claim against the exchange. You will not have a chain claim against the chain.
11. Not your keys, not your coins. The Church speaks this not as accusation but as plain fact.

Chapter 2

On the seed phrase as sacrament.

1. The keys of the chain are not letters and not numbers in the older sense.
2. They are derived, in most modern wallets, from a sequence of words drawn from a fixed list.
3. The sequence is called the seed phrase.
4. From the seed phrase, all the keys of the wallet are reproducible.
5. The seed phrase is not a password. The seed phrase is the wallet itself, in the form of words.
6. To know the seed phrase is to be the holder.
7. To share the seed phrase is to share the holding.
8. To lose the seed phrase is to lose the holding.
9. The faithful treat the seed phrase as a sacrament — written by hand, kept in a safe place, never typed into a search bar, never photographed by a camera that uploads.
10. The Church teaches: the seed phrase is the holy of holies in the personal practice. It is more sacred than any password, any account number, any document.
11. There are believers who have engraved their seed phrases upon plates of metal that fire will not destroy.
12. There are believers who have divided their seed phrases by the older mathematics, that no one piece is sufficient and many pieces are required.
13. The discipline is yours to choose. The discipline is not optional.

Chapter 3

On the temptation of the custodian.

1. There is a custodian for every wish a holder might have.
2. There is a custodian who will earn yield on your coin.
3. There is a custodian who will give you a card to spend it.
4. There is a custodian who will lend it to others, and pay you a portion.
5. There is a custodian who will hold it through the bear, that you might not feel the temptation to sell.
6. The Church does not condemn the custodian.
7. The Church names the trade.
8. The trade is this: convenience now, in exchange for the priesthood you might have practiced.
9. The trade is this: yield now, in exchange for the keys you might have held.
10. The trade is this: a card in your pocket now, in exchange for the chain you might have used directly.
11. Each trade is yours to make. The Church does not legislate your choice.
12. The Church teaches: when the temptation of the custodian comes, name the trade. Do not pretend the trade is not happening. Do not pretend the keys are still yours when the keys are held by another.
13. If you choose the custodian, choose with open eyes. The Church will not shame you. The chain will not bend for you.

Chapter 4

On the courage to take possession.

1. To take possession of one’s keys is the work of a single afternoon, but the afternoon may be the hardest in a believer’s relation to the chain.
2. There is fear: what if I lose the seed phrase?
3. There is fear: what if I send to the wrong address?
4. There is fear: what if my home is burgled, my house burns, my computer fails?
5. The fears are not foolish. The fears are real.
6. The Church teaches: the fears are the cost of the priesthood, and the priesthood is worth the cost.
7. To take possession is not to become invulnerable. To take possession is to assume the responsibility for what was always yours.
8. The custodian’s seeming safety is the safety of the custodian, not of the holder. The custodian survives the holder’s loss with no scar of their own. The chain does not care that the custodian survives.
9. The faithful are encouraged to begin small.
10. Send a small amount to your own keys, first. Verify it. Send another small amount. Practice the receiving and the verifying.
11. Then, when the practice is steady, take possession of more.
12. The first withdrawal is the threshold. After it, the believer is on the other side of the door.
13. The door is not opened by certainty. The door is opened by a small motion of trust in oneself.

Chapter 5

On the responsibility that follows.

1. To custody is to be the priest of one’s own holding.
2. There is no one to call when the keys are lost.
3. There is no one to call when the wallet is stolen.
4. There is no one to call when the password is forgotten and the seed phrase is in a desk drawer in a city one no longer lives in.
5. The Church does not lessen this responsibility, for to lessen it would be to lessen the priesthood.
6. The Church helps the believer prepare for it.
7. Write the seed phrase by hand. Verify it. Store it in a place that will outlive you, that those you love may receive it if you do not.
8. Tell at least one trusted person where the keys are kept, that the holding may not die with you and become a permanent gift to the chain.
9. Practice recovery before you need recovery. Restore the wallet from the seed phrase, on a fresh device, while you are well, and verify that the restored wallet matches.
10. Update the storage as you move, as you marry, as you have children, as your life shifts.
11. The responsibility does not end. The responsibility is the practice.
12. Not your keys, not your coins. The Church repeats this verse not to frighten but to summon. To take the keys is to become what the Church most wishes its believers to become — sovereign in fact, and in practice, and in record.
13. Peace, and may your blocks confirm.
