Spec sheet

Bitcoin, described in full.

One asset, one address per account, one set of rules. Everything the wallet does with your money is on this page, including the parts that are less flattering than a listing page would put them.

BTC
The only asset listed
The unit
Asset
Bitcoin. Nothing else is listed, and nothing else is being prepared.
Ticker
BTC
Symbol
Base unit
1 BTC
Smallest unit
1 satoshi = 0.00000001 BTC. Every balance is a whole number of satoshis.
Precision
8 decimal places, stored exactly. Balances are never rounded for display — the tail digits step back a shade, they are not dropped.
Rounding
None on the way in or out. What you type is what leaves the balance.
The address
Issued
One address per account, created with the account. It does not rotate and there is no second one to keep track of.
Format
A bc1 address, shown in full only when you ask for it. Everywhere else it sits behind a bar.
Entry
Pasted in full. Nothing is auto-completed and nothing is guessed from a partial match.
Address book
There is none. No list of who you pay is kept, so none can be handed over.
Your own address
Not a valid destination. A mistaken paste that lands on it is refused rather than moving money in a circle.
Unknown address
Refused before anything leaves your balance. A destination has to be an account here for the transfer to be accepted.
Movement and cost

What a transfer actually does.

This wallet is custodial. A transfer is a pair of entries on our own ledger, not a transaction broadcast to the Bitcoin network, and the sheet says so rather than borrowing the network's language.

Custody
We hold the balance. It sits on our ledger against your account, not on a key that only you hold.
A transfer
Two entries, written together. Your balance falls by the amount plus both fees; the recipient's rises by the amount.
Timing
Immediate. There is no block to wait for and no confirmation count, because nothing is broadcast anywhere.
Destination
Another account on this platform. Addresses outside it are refused, so the wallet cannot pretend to reach them.
Record
Both sides get a row: amount, counterparty address, network fee, platform fee and timestamp. The arithmetic can be checked afterwards.
Reversal
None. Once the recipient's balance has risen we do not reach into it, so read the destination before you confirm.
Insufficient balance
A send is accepted only if the balance covers the amount and both fees together. Short of that it is refused and nothing moves.
Reference rate
$88,539.81 per BTC, configured rather than quoted. It is used to show a dollar equivalent beside a balance. Nothing is bought or sold at it, and BTC is the authoritative figure everywhere.

The flat network fee is 0.00010000 BTC per send and the platform fee is 1% of the amount. There are no tiers and no volume schedule, so this example scales in a straight line.

Other assets: none.

There is no waiting list and no roadmap. If a second asset is ever added it will appear here as another sheet, described to the same depth as this one, and until then this page is the whole listing.
