A New Standard for Self-Custody
A new standard
for self-custody
Start Bitcoin self-custody
with Coconut today
Why Coconut is different
Signing device and view-only wallet,
fully separated
We refused to trade security for convenience—or the other way around. By design, we split Coconut Vault from Coconut Wallet so you can manage Bitcoin as safely as possible.
Coconut Vault
Signing device
Install on a dedicated phone and use it fully offline. The moment it connects to the outside world, use is blocked.
Coconut Wallet
View-only wallet
Install on your everyday phone. It reads live data from your Bitcoin node.
Sending a transaction
The easiest way
to send a transaction
STEP 1
Build the transaction in Wallet
STEP 2
Scan with Vault
STEP 3
Sign in Vault
STEP 4
Scan the signed data back to Wallet
STEP 5
Broadcast to the network
Practice app
Practice first,
then go live
The Coconut practice app is built for anyone starting Bitcoin self-custody for the first time.
Learn the essentials hands-on—quickly and clearly—so you can move past fear and avoid losing Bitcoin to mistakes or gaps in understanding.

Start self-custody today!
coconut.onl uses the .onl TLD on purpose: it sounds like the Korean word 오늘 (oneul), meaning “today”—a small hint from our team in Seoul. Start self-custody today on your terms.
