Quantus · QTC · accounting, done honestly
Every satoshi of QTC,
accounted to the planck.
Ledger Desk watches your addresses, detects mining rewards from real chain snapshots, matches every disposal against FIFO / LIFO / HIFO lots with exact integer math, and builds a tax-year report you can hand to an accountant. Your keys, your data, your browser — nothing leaves this page.
1 · Wallet vault
Addresses you control. Each one is checksum-validated (SS58 prefix 189) and you read its human checkphrase back before it is stored.
2 · Auto-detect from chain snapshots
Scans the repo's chain snapshots for your vault addresses and proposes dated events for your review — nothing is added until you confirm it.
data/miners.json × the model reward at the bucket midpoint
(Rn+1 = Rn · (1 − 1/50,000,000), quantized to the
0.01 QTC leaf quantum, anchored at the indexer-observed 0.32 QTC reward at block 137536).
Bucket dates are interpolated from block height at the observed 13.2 s block time.
Pre-window mining (blocks 1–122,536) is one clearly-labeled aggregate — split it by
tax year from your miner logs. Transfers: every ≥ 1 QTC move touching your addresses
in data/flows.json (the snapshot floor — dust below 1 QTC is not captured).
3 · Event ledger
The single source of truth. Inflows create cost-basis lots; outflows consume them. Edit anything — the report recomputes instantly.
| Date | Type | Address | Amount | Price | Note | Source |
|---|
4 · Price table
QTC is not listed anywhere yet, so there is no market feed to pull. Enter the USD price you actually used — the price on your exchange receipt, your OTC trade, or your own good-faith estimate — and the desk applies the latest entry on or before each event's date. Events with no applicable price are flagged, never silently zeroed.
5 · Cost basis
Exact integer math on plancks and microdollars — no floating-point drift. Pick the method your jurisdiction expects; the report follows it.
| # | Acquired | Source | Qty (QTC) | Unit cost | Basis | Status |
|---|

7 · How crypto taxes work (U.S. primer)
Mining income
Under long-standing IRS guidance (Notice 2014-21), mined coins are ordinary income at their fair market value on the day you receive them — and that FMV becomes your cost basis for later disposals. Record the date, amount, and FMV of every payout.
Disposals
Selling, spending, or trading QTC is a disposal: gain or loss = proceeds − basis. Hold more than a year and it is generally long-term (lower rates); a year or less is short-term. Moving coins between your own wallets is not a disposal — mark it internal above.
Gifts
Gifting crypto generally does not trigger gain for you; your basis carries over to the recipient. The desk removes gifted lots with no gain recorded — keep the recipient's records too.
Record-keeping
- Every acquisition: date, amount, FMV, source (pool, buyer, block)
- Every disposal: date, amount, proceeds, which lots it came from
- Miner logs for pre-window rewards the snapshots cannot itemize
- Export this ledger yearly and keep it with your return
