Designed for high-conviction traders with limited capital.
The first leveraged trading platform for BTC prediction markets on Sui. Strike lets traders collateralize SUI to open leveraged positions on DeepBook Predict markets.
When a user deposits SUI, Strike executes the Margin Loop in a single Move transaction:
- Borrow — draw dBUSDC from DeepBook Margin against SUI collateral
- Swap — exchange dBUSDC for the target asset via DeepBook
- Deploy — open a leveraged position on DeepBook Predict
Positions are continuously scored by an on-chain kinked interest rate Health Factor. Undercollateralized positions can be liquidated by any permissionless keeper bot, which earns a 2% FIFO fee — no centralized clearinghouse required.
The core Move package. Manages the full position lifecycle (PENDING_OPEN → OPEN → CLOSED / LIQUIDATED), computes the on-chain health factor, and orchestrates cross-protocol calls across DeepBook Margin and Predict in a single atomic transaction.
User-facing Fastify API. Implements a server-custodial zkLogin flow via Enoki — the server holds the ephemeral key, builds the ZK proof, and sponsors every transaction so users never need gas. Handles auth, position intents, and delegates execution to the keeper.
Permissionless off-chain service that executes the Margin Loop and monitors open positions. On open: borrows dBUSDC, swaps, and deploys into Predict. On close: unwinds and repays. Also scans for undercollateralized positions and triggers liquidation to earn the protocol fee.
React 19 trading UI. Google sign-in (no wallet required), position dashboard, and market browser. Communicates exclusively with the backend — users interact with the chain without ever touching a transaction directly.
