PLUG for iPhone

Stack sats.
Keep them.

A hardware wallet extension built for one thing: accumulating bitcoin with clear eyes and discipline. Receive, send, lock for the future, share with family. Never a key on the phone.

Your hardware wallet signs, over Bluetooth. Private testing now.

PLUG home screen: total in sats, the Stack card, an exchange balance, and the rows to add a multisig wallet or a vault
The idea

Accumulate with clear eyes.
Keep with discipline.

Most people lose bitcoin to themselves: addresses reused, coins they cannot see, a sale at the bottom. PLUG puts the discipline in the wallet, not in your willpower. A fresh address every time. A stack you can read at a glance. Locks you set when you are calm, that hold when you are not.

The letter is why you hold. PLUG is how you keep

Zero keys on the phone.

Your hardware wallet signs every transaction on its own screen. PLUG only ever holds public keys. Lose the phone, lose nothing.

0

Private keys stored

Balances, addresses and coin control all run watch-only from your public keys.

1

Address per deposit

A fresh address every time. Never reused, never mixed. Change goes to a fresh one too.

Fee guard

Anything above three times the fastest rate is refused. No accidental 500 sat/vB.

The Send screen: coin control, the UTXO list, fee in sats and sat/vB, change to a fresh address, and the transaction flow
Send

Sign with your eyes open.

Pick the exact coins. See the fee in sats and in sat/vB, the change going to a fresh address, the whole flow drawn out. Only then does your hardware wallet see it.

The stack

See your stack.

Clear eyes start here. Not a number, a picture: every coin is a tile, size is value, colour is age. You know what you own and what it costs to move before you decide anything. Freeze what you never spend. Dust stands out before it costs you fees.

The Stack screen: balance in sats, Receive and Send, the stack drawn as a treemap with its legend
Vault

For the day you're not here.

Lock the coins you never mean to touch. Pick a date: until then nobody can spend, not even you. Decide once, when you are calm, and the network holds the line for you. Add an heir: their key opens the vault a year after yours would. Inheritance without a lawyer, a company, or trust.

Every vault comes with its recovery kit. It opens in Bitcoin Core or Liana too, no PLUG required.

The New vault screen: opening date with 1 month to 1 year and halving shortcuts, the block height written in the script, and the heir key switch
The New multisig screen: signatures required, total keys, the quorum, and this Ledger as key 1
Multisig

With family.
For business.

Discipline you share: no single key, and no single mood, moves the money. Two, three, up to five keys, each on its own device, in its own place. A timelocked recovery key means one lost key never locks the funds forever.

Cosign from Sparrow, Coldcard or another PLUG. Every key gets the same kit.

Works with your hardware wallet.

Over Bluetooth, straight from your pocket. The phone shows, the device signs.
