Glossary
The words you’ll meet across DeepBookie — the markets it trades, the Sui transaction model, and the parts of the agent itself. One line each. Deeper pages are linked from Concepts and Surfaces.
Markets & instruments
| Term | Definition |
|---|---|
| Predict | Sui’s on-chain prediction market, and one of the two markets DeepBookie trades. You bet yes/no on a price by an expiry. On testnet it’s BTC-only, settled in dUSDC. |
| Spot | DeepBook V3’s order book, the other market DeepBookie trades. Real swaps and limit orders — not an automated pool. |
| Oracle / market | An oracle is the price feed a market settles against. A market is one oracle plus a strike and an expiry. |
| Strike | The price a bet is measured against. It wins up if the oracle is above the strike at expiry, down if below. |
| Expiry | The time a market settles (epoch milliseconds, matching Sui’s Clock). At expiry it reads the oracle and pays out. |
| Binary vs range | Binary: one side of a single price (up or down). Range: the price lands in a band (e.g. $68k–$72k). |
| dUSDC | The test settlement token (6 decimals). Operator-gated — get it from the in-app “Get dUSDC” button or the tally form, not a public faucet. |
Liquidity & pricing
| Term | Definition |
|---|---|
| PredictManager | Your on-chain account that holds your dUSDC and positions. You create one before betting or supplying liquidity. |
| PLP vault | The liquidity pool that takes the other side of every bet, so you trade against the pool instead of another person. |
| SVI | A math model of how option prices change across strikes. DeepBookie uses it to compute fair odds for any bet. |
| N(d2) | A standard formula (from Black-Scholes) that turns volatility into a 0–100% probability — e.g. “the chance BTC is above $70k.” |
Transactions & the agent
| Term | Definition |
|---|---|
| PTB (programmable transaction block) | Sui’s transaction format — several on-chain calls run as one. Every DeepBookie write returns one of these, unsigned. |
| Sign at the edge | DeepBookie builds the unsigned transaction but never holds a key. You sign in your wallet (web) or on your machine (CLI/MCP) — never in the cloud. |
| Receipt | The record returned after a signed transaction runs (digest and effects) — your proof a bet, deposit, or claim landed on-chain. |
| MCP | Model Context Protocol — the standard that exposes DeepBookie’s tools to clients like Claude Desktop, via the @deepbookie/mcp package. |
Note
Prices and strikes are stored as integers ×1e9 (FLOAT_SCALING); dUSDC uses 6 decimals (×1e6). Different scales — see Scaling & units before converting.
Tip
Reads are free and need no signature. Only writes return an unsigned transaction — nothing leaves your wallet until you sign it.
