Chapter I
The Ledger
Every account, one book.
Exchanges, wallets and chains resolve into a single list of positions, valued in one currency at one moment. When an asset sits in four places, you see one number and the four places behind it.

The alphabet of the blockchain
Read the chain.
Everything that has ever happened in crypto is written on-chain, in public, forever. We build the tools that read it, for traders and for blockchain experts.
Block 0 · January 3, 2009
Page one.
An unknown author wrote the first page, and left a newspaper headline inside it: a government about to bail out its banks. It is still there. Anyone can read it.
Block 57,043 · May 22, 2010
The first price.
Ten thousand bitcoin bought two pizzas. Nobody thought it mattered. It is on the page forever.
Block 210,000 · November 28, 2012
The first halving.
The reward for writing a page fell from 50 bitcoin to 25, exactly on schedule. No meeting. No vote. The code simply kept its word.
Block 840,000 · April 2024
The fourth halving.
The reward fell to 3.125. Hundreds of thousands of pages in, the book has only ever gone one way: forward.
Block … · Now
The newest page.
Written minutes ago, in public, by no one in particular. It is the largest open book in history, and you are already in it.

The idea
A book this large needs an alphabet.
In the ninth century, two brothers set out to give the Slavic peoples a way to write their own language. The script that grew from their work carries one of their names: Cyrillic.
We took that name for the same reason. The chain is the largest public book ever written, and it needs letters of its own. Here are the first twelve. Each one is live.
Live public data from Blockstream, PublicNode, CoinGecko, Hyperliquid, Binance, Alternative.me and DefiLlama. For information only.
The twelve readers
Which letter are you?
Every trader reads the chain differently. Four questions will find the letter that reads like you.
Question 1 of 4
The market drops 8% while you sleep. Your first move?
You are .
What we build
Two kinds of reader. Two tools.
Traders read the market. Blockchain experts read the chain itself. We are building a tool for each, on the same exact, verifiable data.

The thirteenth letter
Twelve letters are the market. Я is you.
Я is the last letter of the alphabet and, in the languages that end with it, the word for I. It is the one letter no public chart can show, because it is your own book: every exchange, wallet and position, read as one page.
The Reader
Your whole book, on one page.
This one is running now. The portfolio is fictional, but the prices are real and moving as you read. Change the range, trace the curve, or hide every figure with a single touch.

Inside the Reader
Five things beyond the price.
An exchange shows you a balance. The Reader tells you what it means, in five chapters.
| Gross profit | +$2,400 |
|---|---|
| Trading fees | −$2,000 |
| Slippage | −$800 |
| Funding | −$90 |
| What you kept | −$490 |
A winning month that lost money.
Chapter II
The True Figure
What you actually kept.
Gross profit flatters. Fees, funding and slippage are drawn out of every trade, so the figure you read is the figure you kept, not the one you hoped for.
Chapter III
The Exposure
What you are really betting on.
Five tokens that move together are one bet wearing five names. Cyrillic Metrics measures concentration and correlation across the whole book, so hidden size stops being hidden.
Chapter IV
The Sentinels
Silent until it matters.
Set limits on what can actually hurt you: drawdown, concentration, distance to liquidation, a stablecoin leaving its peg. Everything else stays quiet.
Chapter V
Discretion
Your book is nobody’s business.
Read-only connections. No custody. No ability to trade or withdraw. A single touch hides every figure on your screen, wherever you happen to be sitting.

The chain, as data.
For analysts, quants and engineers who build on chain. Decoded blocks, mempool, contract events and wallet flows, as clean Python objects, an API and a live stream.
In development. This preview is already running on live chain data.

On-chain, live
Three chains. Three heartbeats.
Bitcoin writes a page about every ten minutes, Ethereum every twelve seconds, Solana several times a second. Here are all three as they happen, read straight from the chains by your own browser.

The mathematics of recovery
A loss is never the size it looks.
The climb back always grows faster than the fall. This is arithmetic, not opinion, and it is why seeing risk early matters more than any entry.

- +100%

The Scribes' Oath
Four things we will never do.
- I
We will never hold your assets.
- II
We will never place a trade.
- III
We will never sell your data.
- IV
We will never tell you what to buy.
