Creating Ethereum, Bitcoin and other accounts is complex and fraught
12+
with potential for loss of funds.
13+
14+
All Crypto wallets start with a "Seed": a large, random number used to
15+
generate all of the actual Bitcoin, Ethereum, etc. wallets.
16+
17+
The best practice for using these wallets is to load this "Seed" into a
18+
secure hardware device, like a Trezor hardware wallet. SLIP-39 Mnemonic
19+
cards contain the recovery words, which are typed directly into the
20+
Trezor device to recover the Seed, and all of its accounts.
21+
22+
The [macOS and win32 SLIP-39 App] helps you generate Mnemonic cards and
23+
back up this seed, securely and reliably, by distributing Mnemonic cards
24+
for the seed to partners, family and friends. Also, encrypted "Paper
25+
Wallets" can be output, to support software cryptocurrency wallets such
26+
as Metamask, Brave or various mobile phone wallets.
27+
28+
Later, if you (or your heirs!) need to recover the accounts, they can
29+
collect a sufficient threshold of the cards and regain access to all of
30+
the cryptocurrency accounts related to the seed.

For both BIP-39 and SLIP-39, a 128-bit or 256-bit random "Seed" is the
53+
source of an unlimited sequence of Ethereum, Bitcoin, etc. HD
54+
(Hierarchical Deterministic) Wallet accounts. Anyone who can obtain
55+
this Seed gains control of all Ethereum, Bitcoin (and other) accounts
56+
derived from it, so it must be securely stored.
57+
58+
Losing this Seed means that all of the HD Wallet accounts are
59+
permanently lost. Therefore, it must be backed up reliably, and be
60+
readily accessible.
61+
62+
Therefore, we must:
63+
64+
• Ensure that nobody untrustworthy can recover the seed, but
65+
• Store the seed in many places with several (some perhaps
66+
untrustworthy) people.
67+
68+
How can we address these conflicting requirements?

1.1 SLIP-39 Mnemonic Recovery Cards
72+
───────────────────────────────────
73+
74+
We don't recommend writing down one BIP-39 12-word or 24-word Mnemonic
75+
phrase, and hoping that *you* can find it, but that nobody else *ever*
76+
finds it!
77+
78+
Instead, generate a number of SLIP-39 Mnemonic cards, which can be
79+
collected to recover the Seed:

and recovery capability. Enter the words on the SLIP-39 cards
105+
directly into the screen of the Trezor to recover your Cryptocurrency
106+
accounts.
107+

wallet yet supports direct, on-screen SLIP-39 Seed recovery. This

exchanges is [Netcoins.app]; sign up with this referral link, and we
123+
both get some benefits.
124+
125+
They have higher than typical Interac e-transfer limits, which is very
126+
nice. However, they don't support a wide range of cryptocurrencies;
127+
presently, only BTC, ETH, XRP, LTC, BCH, USDC, and a few other
128+
lesser-known coins.

2.4 Protecting your SLIP-39 Cards
148+
─────────────────────────────────
149+
150+
Protect your printed SLIP-39 cards from water damage by laminating
151+
them in plastic or storing them in [zip-loc bags] before [mailing
152+
them].
153+
Print the SLIP-39 cards and cut them out, and then lay them out with
154+
1/2" margins (so you can cut them out after lamination and retain 1/4"
155+
borders), either with [self-adhesive full-page laminating sheets] - no
156+
machine required (or [index-card size]),
157+
or with a [heat-laminating machine] in [full-page pouches] (or in
158+
[index-card size pouches]).
